Half a Century of Stress Research: a Tribute to Hans Selye by His Students and Associates* EXPERIENTIA Volume 41/No. 5 Pages 55%700 15 May 1985 Reviews Half a century of stress research: a tribute to Hans Selye by his students and associates* Hans Selye died in 1982 in Montreal, Canada, at the age of 75. A native of Austria and Hungary, he did a fellowship at Johns Hopkins University, then went to McGill University for more than a decade of research and subsequently he founded the Institute of Experimental Medicine and Surgery at the University of Montreal in 1945. He remained at the Institute until his forced retirement one year prior to his death. Towards the end of his career he established the International Institute of Stress where he was active virtually until the last few weeks of his life. By his own account, his ideas and early experiments substantially preceded the historical short report on 'A syndrome produced by diverse nocuous agents' published in the 4 July 1936 issue of'Nature'. Hence, it is appropriate to label his efforts as a half a century quest for the characterization and elucidation of biologic stress. On the first anniversary of Dr Selye's death his former students and coworkers gathered in Montreal to commemorate the scientific achievements that can be associated with Dr Selye's institute. The program of this two-day Symposium Hans Selye consisted of historical interludes and brief reviews on ongoing research by those who are still active in investigative work. Two special lectures were presented by Dr Julius Axelrod of the National Institutes of Health and Dr Judah Folkman of Harvard Medical School. Both of these prominent scientists knew Dr Selye quite well personally and they contributed significantly to the success of the symposium. The organizing committee of the symposium consisted of Drs Andr6 Robert, Sandor Szabo and Yvette Tach6. The present tribute consists of a few historical reviews by graduates of Dr Selye's institute and a series of brief scientific overviews by his former students and associates. The breadth and diversity of these presentations also illustrate the wide scientific basis of research related to biologic stress as well as the flexibility guaranteed by training in Dr Selye's famous institute.

His most important scientific contributions include in 1936 the evidence that the pituitary–adrenal–thymus axis was activated by vari- ous nocuous stimuli, which led to the involution of the thymus and of the lymphoid organs; in 1946, the theory of general adaptation syndrome (GAS), pointing out that this is a general reaction that leads to resistance of the organism to various insults. This review article is focused on the general interest of Selye on the important role played by mast cells in different pathological conditions and in particular in calciphylaxis and calcergy, summarized in a classic book, which is a lasting contribution on the subject.

His experiments with rats led to recognition of the “general adaptation syndrome”, later renamed by Selye “stress response”: the triad of enlarged adrenal glands, lymph node and thymic atrophy, and gastric erosions/ulcers. Because of the major role of glucocorticoids (named by Selye), he performed extensive structure–activity studies in the 1930s–1940s, resulting in the first rational classification of steroid hormones, e.g. corticoids, testoids/androgens, and folliculoids/estrogens. During those years, he recognized the respective anti- and pro-inflammatory actions of gluco- and mineralocorticoids in animal models, several years before demonstration of anti-rheumatic actions of cortisone and adrenocorticotrophic hormones For personal use only.

  • Stress and the Brain: Individual Variability and the Inverted-U
    Stress and the brain: individual variability and the inverted-U Robert M Sapolsky Nature Neuroscience 18, 1344–1346 (2015) doi:10.1038/nn.4109 Published online 25 September 2015 It is a truism that the brain influences the body and that peripheral physiology influences the brain. Never is this clearer than during stress, where the subtlest emotions or the most abstract thoughts can initiate stress responses, with consequences throughout the body, and the endocrine transducers of stress alter cognition, affect and behavior. For a fervent materialist, few things in life bring more pleasure than contemplating the neurobiology of stress. The early years of the field of stress biology were dominated by the first half of the neuroendocrine loop, namely the ability of the brain to initiate the body's stress response. Stress physiology was born early in the last century, in the Paleolithic era of Walter Cannon implicating the sympathetic nervous system in the 'fight or flight' response, and in Hans Selye identifying glucocorticoids as the other main mediator of the stress response. These foundational findings took the field in many directions. One was the revolutionary work of Geoffrey Harris, Roger Guillemin and Andrew Schally showing that the brain is an endocrine gland, secreting releasing and inhibiting hormones into the hypothalamic-pituitary portal system; in many ways, the decades-long arc of that revolution was bracketed by stress research, in that corticotropin-releasing hormone was the first of the principal hypothalamic hormones whose existence was inferred physiologically and the last to be isolated and biochemically characterized. The half of the loop concerning the brain regulating the body also encompasses the historic welcoming of psychologists into the field; this came with the demonstration that the stress response, conceptualized in the context of acute physical crisis, can be robustly activated by purely psychological states, such as loss of control, predictability and social support.
