Timeline of aging research

From Wikipedia, the free encyclopedia
(Redirected from 2023 in senescence research)

This timeline lists notable events in the history of research into senescence or biological aging, including the research and development of life extension methods, brain aging delay methods and rejuvenation.

People have long been interested in making their lives longer and healthier. The most anсient Egyptian, Indian and Chinese books contain reasoning about aging. Ancient Egyptians used garlic in large quantities to extend their lifespan. Hippocrates (c. 460 – c. 370 BCE), in his Aphorisms, and Aristotle (384 – 322 BCE), in On youth and old age, expressed their opinions about reasons for old age and gave advice about lifestyle. Medieval Persian physician Ibn Sina (c. 980 – 1037), known in the West as Avicenna, summarized the achievements of earlier generations about this issue.[1][2][3]

Background

[edit]

Descriptions of rejuvenation and immortality remedies are often found in the writings of alchemists. But all those remedies did not allow even alchemists themselves to live longer than a hundred years.[1][2][3]

Though the average lifespan of people through the past millennia increased significantly,[4] maximum lifespan almost did not change - even in ancient times there were fairly well and unbiasedly documented cases when some people lived for more than a hundred years (for example, Terentia who lived 103 or 104 years). While among the billions of people of the modern world, there is only one case of life over 120 years (Jeanne Calment, 122 years). The super-long lives of people that are mentioned in ancient books, apparently, are highly exaggerated, since archaeological data show that even the oldest of the ancient people lived no more than modern supercentenarians.[2] In some cases the exaggeration, possibly, is not intentional but occurs due to errors in translation between languages and synchronization of chronological systems. The species limit of human life is estimated by scientists at 125–127 years,[5][6] and even in the most ideal conditions a person will not live longer due to aging of the body.

Some scientists believe that, even if medicine learns how to treat all major diseases, that will increase the average lifespan of people in developed countries by only about 10 years.[2] For example, biogerontologist Leonard Hayflick stated that the natural average lifespan for humans is 92 years.[7] Meanwhile, the life expectancy for Japanese already now is more than 84 years,[8] and for Monaco it is reported to be more than 89 years.[9] It may not be possible to achieve further increases without development of new biomedical technologies and approaches. Searches of various equivalents of the elixir of youth happened yet in ancient times: people hoped to find a miraculous remedy in faraway territories, tried to use magic and alchemy. Scientific and technological attempts began at the end of the 19th century. For their intended purpose, all of them turned out to be inefficient at best, sometimes led to premature death, but they had many useful and sometimes unexpected consequences.

Timeline

[edit]

Ancient

[edit]
  • 350 BCE — The Greek philosopher Aristotle, arguably the first philosopher to make a serious attempt to scientifically explain aging, proposes his thesis on aging. He suggests that aging is a process by which human and animal bodies, which are naturally hot and wet, gradually become dry and cold, and theorizes that more moisture delays aging.[10][11]
  • 259–210 BCE — years of life of the Chinese emperor Qin Shi Huang, who united China under his rule. All his life he persistently searched for an elixir of youth and died trying, presumably taking "pills of immortality", containing mercury.
  • 15687 BCE — years of life of the Chinese emperor Wu of Han, who persistently tried to find a way to achieve immortality, mainly by means of magic. He used services of various magicians. But Wu of Han was not a naive person – he thoroughly rechecked their abilities and if he identified the person as a quack, he executed him.
  • 63 BC–14 CE — years of life of Caesar Augustus, the first Roman emperor, who is considered one of the most effective leaders of the Ancient Rome. For him an eternal youth was an obsession. In particular, contrary to the Roman tradition to create statues as realistic as possible, he always ordered to portray himself young. There are many of his "youthful" statues but researchers still do not know how he looked in old age.
  • 3rd–17th century — the period of alchemy. There are several directions in alchemy, and it was distributed over a huge territory. But almost everywhere, in one form or another, there was the concept of a "philosopher's stone" – some substance that is able to turn other metals into gold, and when taken internally in small doses, heal all diseases, rejuvenate an old body and even give biological immortality. Alternatively, there were attempts to prepare "pills of immortality". During centuries alchemy gradually transformed to chemistry, in parallel giving birth to many adjacent sciences or enriching them. It is worth noticing the direction of iatrochemistry – a rational direction of alchemy with the main goal of preparing medicinal products. The pioneers of iatrochemistry were Paracelsus (1493–1541), Jan Baptist van Helmont (1580–1644) and Franciscus Sylvius (1614–1672). The converging field of alchemy was transformed into pharmacy.
  • 1513 — searching for the Fountain of Youth is in popular culture thought to be one of the purposes of the expedition of the Spanish conquistador Juan Ponce de León, which lead to the discovery of Florida – however, there is no contemporary evidence of this, and this purpose is considered a myth by historians.[12]
  • 1550 — a Venetian nobleman Luigi Cornaro published the book The Art of Living Long, describing the style of life for the achievement of longevity.[13] The book was translated into many languages. The English version of the book till the 19th century went through more than 50 editions. The main idea of the book: in order to live many years, you need to live in moderation, eat simply and little. In his youth Cornaro led a free and immoderate life, as a result by the age of 35 he had many health problems. But by changing his lifestyle he was able to live to 98 (1467–1566).[14] (Though it is possible that he exaggerated his age by about 17 years to give his recommendations more weight.)

19th century to WWII

[edit]

From the end of the 19th century, systematic scientific and technical studies began on the processes of slowing down aging and possible rejuvenation. The period of world history between the two world wars is a very complicated, difficult and ambiguous time of world history. In many spheres of life, there were ideas that were radical-bold, but not always intelligent, ethical and moral from the point of view of modern knowledge, foundations and norms. This also affected the aging research, the spirit of which corresponded to the spirit of that time: attempting bold experiments, often on people, intensively implementing in practice treatments that we may now consider ridiculous. Those attempts had both bad and good consequences. But those researches were already scientific. As it often happens in science, it is often difficult to establish priority considering, who was the first person beginning to use one or another approach. Usually the first experiments are done by enthusiasts and have doubtful positive effects. Some researchers work in parallel. Then at some moment the persons emerge who developed the approaches and made them public.

  • 1825 The first publication of the Gompertz–Makeham law of mortality that in the simplest form is: p = a + bx. According to the law, the probability of death p is defined as the sum of age-independent component a and the component depending on age bx which with age increases exponentially. If we place organisms in an absolutely protected environment and in this way make the first component negligible, the probability of death will be completely defined by the second component which actually describes the probability to die from aging.
  • 1860s Alfred Russel Wallace writes down what is probably the first evolutionary theory of aging. In notes written sometime between 1865 and 1870, he proposed a wear and tear theory of aging, suggesting that older animals which continue to consume resources, competing with their offspring in an environment with limited food, were disfavored by natural selection. Therefore, he suggested that aging was an evolved trait which allowed an organism's descendants to thrive.[11]
  • 1882 August Weismann puts forward the wear and tear theory of aging independently of Wallace.[15][16]
  • 1889 Rejuvenation experiment conducted on himself by the French doctor Charles-Édouard Brown-Séquard. He made himself a few subcutaneous injections from the testicles of young dogs and guinea pigs and claimed that the injections were accompanied by significant and long pain, but then he observed an improvement of the physical condition of the organism and increase of mental activity. Experiments of other scientists, at first, produced the same results but later it became clear that the period of reinforced activity is followed by a period of decline. At the moment of the experiment Charles-Édouard Brown-Séquard was 72 years old. After the experiment he claimed he felt as if he became younger by 30 years. However, 5 years later he died. But other doctors picked up this method and it created the foundation for the development of hormone replacement therapy.[2][17][18][14]
  • 1903 Ilya Mechnikov coined the term "gerontology".[19][20][3] The term originates from the Greek γέρων, geron, "old man" and -λογία, -logia, "study of". From 1897 to 1916 Mechnikov conducted many studies on the effect of acidified dairy products (especially Bulgarian yogurt and bacteria used for its production) on longevity and quality of life in old age. He developed the concept of probiotic diet that promotes long healthy life.[17][18] In 1908 Mechnikov received the Nobel Prize for his work on immunology (adjacent area of his research).[21] Adhering to his diet, Mechnikov lived a very long life compared to his short-lived relatives.[22]
  • 1914 Dr. Frank Lydston from Chicago performed human testis transplants on several patients, including himself, and said that there were some rejuvenating consequences (such as returning his gray hair to its original color and improving of sexual performance).[14] These works remained little known. The work of Leo L. Stanley, that he began to do since 1919, received much more prominence (see further).
  • 1915–1917 Experiments to find out the effects of food restriction on the life duration of rats, conducted by Thomas Osborne. Apparently, these were the first systematic experiments in this direction.[2][23] These experiments remained little known. The method was popularized by Clive McCay in 1934–1935 (see further).
  • 1910s–1930s Austrian physiologist Eugen Steinach was trying to achieve rejuvenation effects by means of different surgical operations such as partial vasectomy for men, ligation of fallopian tubes for women, transplantation of testicles, etc. And although later these operations were found to be ineffective, they allowed the researchers to recognize the role of the sexual glands and sexual hormones in the formation of the first and secondary sex characteristics, enriched physiology, laid the foundation for the science of sexology, formed the basis for sex reassignment surgeries. From 1921 to 1938, Eugen Steinach was nominated for the Nobel Prize many times (according to various sources, from 6 to 11 times), but never received it.[17][18][24][25][26]
  • 1910s–1930s Numerous experiments for obtaining rejuvenating effects by means of transplantation of organs and tissues. Among the most notable researchers who worked in this direction, there were Alexis Carrel (who developed the technology of anastomosis of blood vessels and advanced asepsis, a Nobel laureate of 1912[27]), Mathieu Jaboulay, Emerich Ullmann, Jacques Loeb, John Northrop, Porfiry Bakhmetiev. And although such interventions were later found to be ineffective for their intended purposes, those works led to the creation of tissue engineering, techniques for cardiopulmonary bypass and dialysis, established the foundation for the technologies for storing organs extracted from a person outside the body (which now are used, for example, during organ donation), the emergence of cryobiology.[17][18]
  • 1920s–1930s In medical practice, sex gland transplants were introduced to obtain rejuvenating effects. (Though separate experiments in this direction were done even earlier, even in antiquity.) The earlier mentioned operations of Dr. Frank Lydston in 1914 remained almost unnoticed. But the works of Leo Leonidas Stanley quickly received widespread scientific notice. Stanley was a physician at a prison in California and began to do these operations since 1919, using glands of executed criminals.[14] In the following years, such operations were done by dozens of physicians (including Eugen Steinach) but they became most famous due to the activity of the French surgeon of Russian extraction Serge/Samuel Voronoff. It was believed that transplantation of sex glands provides more durable effects than injection of a suspension of ground glands. In case of transplantation from human to human, the glands of executed criminals were usually used. But due to a shortage of materials, the sex glands of young healthy monkeys were widely used, which were specially grown for this purpose (usually thin sections of the glands were implanted). In some cases soon after the operation, there were indeed noticeable positive changes in appearance and behavior (with a rapid senility of the body soon following). There were many messages about wonderful results of the operations that, apparently, were false advertising of unscrupulous doctors. But numerous failures became apparent, for which the method was sharply criticized and banned.[2] Serge Voronoff and some other doctors, who claimed producing wonderful results after the operations, got bad reputation. However, despite the failure in the main direction, the conducted research led to the emergence of allotransplantation and xenotransplantation directions in surgery, brought significant knowledge about the effect of sex hormones on the body, stimulated their study.[17][18] It may be just a coincidence but in 1929–33 several varieties of estrogen were discovered, and testosterone was isolated in 1935. Also these experiments formed the basis for several works of public culture (for example, Heart of a Dog by Mikhail Bulgakov, The Adventure of the Creeping Man from the series about Sherlock Holmes, a song Monkey-Doodle-Doo of Irving Berlin).
  • 1926–1928 Experiments on rejuvenation by blood transfusion, conducted by Alexander Bogdanov in the world's first Institute for Blood Transfusion especially created for that purpose. Bogdanov himself died during one of the experiments, because at that time little was known about the factors of blood compatibility of different people.[2][18] The institute, having undergone several renames, exists and is still actively working. The second head of the institute was Alexander Bogomolets (see further).
  • 1930s Beginning of attempts of rejuvenation by methods of cell injections. A special role belongs here to the Swiss physician Paul Niehans – he was not the first but he was the one who developed this approach the most. Among his patients there were many famous people (including Winston Churchill, Charles de Gaulle, Pope Pius XII).[2][17] So, in 1952, about 3000 injections of about 10 cm3 of cell suspension were reported. As a consequence, cell therapy and regenerative medicine were formed. Since the 1960s, attempts have been made to inject not only whole cells but also their constituent parts (such as isolated DNA and RNA).[17][18] But usage of embryonic drugs sometimes caused serious complications, so the American association of physicians recognized the method of cell therapy as dangerous.[2]
  • 1930 The first world's journal about aging and longevity. It was established in Japan and has the name Acta Gerontologica Japonica (Yokufuen Chosa Kenkyu Kiyo).[28]
  • 1933 The first institute in the world dedicated to study of aging. It was created in Kishinev (at that time inside the Kingdom of Romania) by Dimu Kotsovsky. Initially the institute was maintained by his own means, and was subsequently recognized by the Romanian government. The name is Romanian: Institutul Pentru Studierea si Combaterea Batranetii = German: Institut für Altersforschung und Altersbekämpfung = Institute for The Study and Combat of Aging.[29]
  • 1934 The first widely known scientific publication on the impact of dietary restriction on life expectancy, authored by Clive McCay.[30][31][32] McCay's group carried out intensive research in this direction in 1930–43, soon other scientists began to do related research.[2] The effect of increasing life expectancy by starvation is usually observed in rats and mice, whose development until puberty is very labile (growth retardation and puberty, decreased metabolism and body temperature). In larger animals, such as rabbits, dogs and monkeys, the effect is less pronounced. The impact of fasting on human life expectancy still remains a question where not everything is clear and is unambiguous.[2]
  • 1936 The first European (and Western) journal about aging and longevity. It was published in Kishinev by Dimu Kotsovsky. During the first year of existence it was called Monatsberichte,[33] then got the name German: Altersprobleme: Zeitschrift für Internationale Altersforschung und Altersbekämpfung = "Problems of Aging: Journal for the International Study and Combat of Aging". The journal published materials mostly in the German language, less in French and English.[29]
  • 1937 A Ukrainian Soviet pathophysiologist Alexander Bogomolets created antireticular cytotoxic serum in the hope to extend life of people to 150 years. Although the drug did not achieve its main goal, it has become widely used for the treatment of a number of diseases, especially infectious diseases and fractures.[2][17][18] The serum of Bogomolets was actively used in Soviet hospitals during WWII. For his work, Alexander Bogomolets received in 1941 the Stalin Prize,[34] which for Soviet scientists of those years was even more important than the Nobel Prize.
  • 1938 The first specialized society dedicated to the study of aging. It was formed in Germany, Leipzig and was named the German Society for Aging Research (German: Deutsche Gesellschaft für Altersforschung, soon renamed to Deutsche Gesellschaft für Alternsforschung). The founder is Max Bürger [de]. He also established the specialized journal Zeitschrift für Altersforschung – it is already the third such journal in the world after the previously mentioned Japanese and Romanian journals.[35]
  • 1938 The world's first scientific conference on aging and longevity in 1938 in Kiev, that was convened by Alexander Bogomolets.[1][36]
  • 1939 In the United Kingdom, the British Society for Research on Ageing is formed. The founder is Vladimir Korenchevsky who emigrated there from the former Russian Empire.[1]

After WWII

[edit]

After World War II, research tools and technologies of another level appeared. Thanks to these technologies, it became understandable what really occurs inside cells and between them (for example, the model of the DNA double helix was created in 1953). At the same time, changed ethical norms did not allow cardinal experiments to be performed on humans, as had been possible in previous decades. Consequently, the influence of different factors could be estimated only indirectly.

  • 1945 In the US, the Gerontological Society of America is formed. The founder is Edmund Vincent Cowdry.[1]
  • 1950 Largely thanks to the collaborative efforts of Korenchevsky and Cowdry, the International Association of Gerontology is formed, later renamed to the International Association of Gerontology and Geriatrics (IAGG). The organization was registered in Belgium, and that is where its first conference took place. Slowly, gradually, the ideas began to spread that the problems of aging cannot be solved within the framework and efforts of one nation – therefore the international interaction is necessary.[1]
  • 1952 Peter Medawar proposed the mutation accumulation theory to explain how the aging process could have evolved.[15][37][4]
  • 1954 Vladimir Dilman formulated the hypothesis of aging that at first become known only in the USSR, as the elevation hypothesis. In 1968 it took the form and became known as the neuroendocrine theory of aging.[38][39][40]
  • 1956 Denham Harman proposed the free-radical theory of aging and demonstrated that free radical reactions contribute to the degradation of biological systems.[41] The theory is based on the ideas of Rebeca Gerschman and her colleagues put forward in 1945.[42]
  • 1957 George Williams proposed the antagonistic pleiotropy hypothesis for the explanation of the emergence of aging.[4][43]
  • 1958 Physicist Gioacchino Failla proposed the hypothesis that aging is caused by the accumulation of DNA damage.[44] The next year the hypothesis was developed by the physicist Leo Szilard,[45] resulting in a number of related theories under the general name DNA damage theory of aging.
  • 1961 Discovery by Leonard Hayflick of the limit of divisions for somatic cells, named the Hayflick limit. Hayflick found that normal human cells, extracted from fetus, are able to divide only about 50 times, after that they enter a senescence phase.
  • 1969 Immunological theory of aging proposed by Roy Walford.[46]
  • 1974 Formation of the National Institute on Aging (NIA) – the aging of the population began to be perceived as a problem deserving state attention (and not as a problem of separate scientific societies). Since 1984, the NIA has begun to contribute in every way to the work of the National Archive of Computerized Data on Aging (NACDA).
  • 1977 To explain aging, Thomas Kirkwood proposed the disposable soma theory. According to the theory, the organism has only a limited amount of resources that it has to allocate between different purposes (such as growth, reproduction, repair of damage). Aging occurs due to the limitation of resources that the body can afford to spend on repair.[4]
  • 1985 The discovery of telomerase, a ribonucleoprotein that is able to restore shortened telomeres. The discovery was made by Elizabeth Blackburn and Carol Greider.[47][48] This research is based on the theoretical works of Alexey Olovnikov.[48][49][50] The study of telomeres and telomerase required many more years and the work of many scientists around the world. For this work, in 2009, Elizabeth Blackburn, Carol Greider and Jack Szostak received the Nobel prize,[51] in the same year Alexey Olovnikov was awarded the Demidov Prize.[52]
  • 1986 Reliability theory of aging and longevity proposed by Leonid Gavrilov and Natalia Gavrilova. At first it was published only in the USSR.[53] In English language the theory was published five years later, in 1991.[54][55][56]
  • 1990 Formation of the Gerontology Research Group (GRG) which searches for supercentenarians around the world and verifies their age. Whenever possible, the organization tries to collect data on why these people live significantly longer than the average person. The organization regularly publishes a list of the oldest verified living supercentenarians.[57]
  • 1992 National Archive of Computerized Data on Aging (NACDA) published in the Internet the first 28 datasets related to aging. Gradually the number of published datasets has grown to over 1600 and continues to grow. These datasets are available to any researcher around the world at no charge, so they can search in them for new patterns. The site also provides some tools to facilitate analysis.[58]
  • 1993 Cynthia Kenyon and Ramon Tabtiang doubled the lifespan of C. elegans nematodes by partially disabling a gene, with the nematodes remaining relatively healthy for significantly longer. The discovery was a revolutionary breakthrough in aging research, demonstrating that the aging process could be controlled in the laboratory, and sparked more research into the molecular biology of aging.[59][60]
  • 1995 Method for detection of senescent cells using a cytochemical assay.[61]
  • 1997 The absolute record for the duration of human life. The French woman Jeanne Calment lived 122 years and 164 days (the record is still held).
  • 1998 A record for the duration of life among males. The Danish-American Christian Mortensen lived 115 years and 252 days.
  • 1998 Scientists managed to extend, in a laboratory environment, the life of normal human cells beyond the Hayflick limit using telomerase.[48][62]
  • 1999 Establishment of the Buck Institute for Research on Aging – the first institute originally established primarily to study intervention into the aging process.
  • 1999 Sierra Sciences, a biotechnology company focused on aging research with the goal of curing human aging, was founded by William H. Andrews.

21st century

[edit]

The research activity has increased. There is a shift of focus of the scientific community from the passive study of aging and theorizing to research aimed at intervening in the aging process to extend the lives of organisms beyond their genetic limits. Scientific-commercial companies appear, which aim to create practical technologies for measuring the biological age of a person (in contrast to chronological age) and extend the life of people to a greater extend than the healthy lifestyle and preventive medicine can provide. In society and media there are discussions not only about whether a significant prolongation of life is physically possible, but also whether it is appropriate, about the possibility of officially classifying aging as a disease, and about the possibility of mass testing on human volunteers.

  • 2003 First evidence that aging of nematodes is regulated via TOR signaling.[30][63]

  • 2018 The World Health Organization included in the international classification of diseases ICD-11 a special additional code XT9T, signaling the relationship of a disease with age. Due to this, after the final approval of the ICD-11 in May 2019, aging began to be officially recognized as a fundamental factor that increases the risk of diseases, the severity of their course and the difficulty of treatment.[96][109][110][111][112]

  • Scientists report, using public biological data on 1.75 m people with known lifespans overall, to have identified 10 genomic loci which appear to intrinsically influence healthspan, lifespan, and longevity – of which half have not been reported previously at genome-wide significance and most being associated with cardiovascular disease – as well as haem metabolism as a promising candidate for further research within the field.[125][79]
  • Scientists report that after mice exercise their livers secrete the protein GPLD1, which is also elevated in elderly humans who exercise regularly, that this is associated with improved cognitive function in aged mice and that increasing the amount of GPLD1 produced by the mouse liver in old mice could yield many benefits of regular exercise for their brains – such as increased BDNF-levels, neurogenesis, and improved cognitive functioning in tests.[126][127]
  • Scientists report that yeast cells of the same genetic material and within the same environment age in two distinct ways, describe a biomolecular mechanism that can determine which process dominates during aging and genetically engineer a novel aging route with substantially extended lifespan.[128][129]
  • Reprogramming progress[130]

  • Researchers demonstrate antibody-mediated depletion of myeloid-biased hematopoietic stem cells against immune system aging with mice.[272][273]
  • An experiment by researchers at Imperial College London, the MRC London Institute of Medical Sciences, and Duke–NUS Medical School found that reduction in levels of the protein interleukin 11, which increases in the body with age and in excess is responsible for increased inflammation, reversed some aspects of aging in mice. The experiment, which involved genetically engineering some mice to block the production of the protein and allowing others to reach middle age before giving them a drug to eliminate it from their bodies, increased their lifespans by 20-25% and reversed numerous effects of aging.[274]
  • Precious3GPT, an artificial intelligence model designed to assist in aging research and drug discovery, is launched.[275]
  • A study by scientists at Stanford University found that rather than being a solely gradual and linear process, aging accelerates dramatically at two points in a human lifetime. The study, which tracked thousands of different molecules in 108 people aged between 25 and 75, found that age-related changes rise substantially in two waves, with the first occurring at around age 44 and the second at around age 60.[276][277]
  • Researchers at the IRB Barcelona demonstrated that senescent cells release mt-dsRNA into the cytosol driving the SASP via RIGI/MDA5/MAVS/MFN1, and in turn are hypersensitive to mt-dsRNA-driven inflammation due to reduced levels of PNPT1/ADAR1. Moreover, senescent cells within fibrotic and aged tissues also present increased dsRNA foci, and inhibition of mitochondrial RNA polymerase reduces systemic inflammation associated to senescence.[278]
