Hans Selye and the stress response: 80 years after his “letter” to the Editor of Nature

The effects of chronic stress are being investigated in a number of domains-including cardiovascular diseases. Depressive state is prevalent in coronary heart disease CHD patients and increases risk for acute coronary syndrome ACS recurrence and mortality despite optimal medical care.

Research has shown that psychological stress can trigger ACS and sudden cardiac death. The pathways underlying this risk remain non-elucidated [9]. He showed that rats develop similar hypertrophy of the adrenals, involution of lymphatic organs and gastric erosions in response to exposure to harmful agents independently of their chemical or physical nature. As we reported CRF was one of the first hypothalamic releasing factors to be named and characterized.

Convicting evidence established that CRF receptors mediates the peripheral effects of the CRF signaling system on the heart and blood vessels; CRF2 being densely expressed in the cardiovascular system [10].

In contrast to short-term stressors, chronic stress has been shown to suppress or dysregulate immune function [11]. Hans Selye has also a historic role in the classification of steroids.

He had a focused research on steroid hormones originating from the adrenal cortex that play a crucial role in stress response. He performed the chemical and structural approach to steroids in the s and s. Selye was also one of the firsts to demonstrate that stress is associated with induction or exacerbation of ulcers in the stomach; and duodenum. In s it is demonstrated that compounds such as propionitrile or cysteamine selectively induced duodenal ulcer in the rat [13].

Now, with the development of biochemistry and cellular fields, biological formulations of stress appeared; extending the initial stress concept established by Hans Selye.

Hans Selye MD PhD

There are few data available at present that implicate the different stress psychological, cellular: oxidative, mitochondrial, reticular. Eighty years later, more than , published articles discuss the contributions of the stress in PubMed data. Numerous applications have been proposed for the concept of stress, each focusing on aspects of an internal or external challenge, on stimulus perception by an organism; or on a physiological and cellular response to the stressors Both mitochondria and the endoplasmic reticulum ER are suitable of adaptive responses.

Mitochondrial stress and ER stress are central to the maintenance of cellular homeostasis.

Indeed, an evidence of considerable cross-talk between the two organelles exists. Now there is increasing recognition of an interaction between the functions of mitochondria and ER with oxidative metabolism validated via oxidative stress [14,15]. Concerning the whole aspects of oxidative stress, the cumulative number of papers published exceeds , since The term began to appear in the s, coincident with superoxide and superoxide dismutase discovers [16].

In conclusion, now, the concept of stress is extended to biological parameters. Physiological homeostasis is a dynamic equilibrium of the body maintained by the interplay of various biological process associated to the live. Isolation and amino acid sequence of alpha2-corticotropin-releasing factor alpha2-CRF from hog pituitary glands.

Endocrinology ;— This, paired with his observation that people with different diseases exhibit similar symptoms, led to his description of the effects of "noxious agents" as he at first called it. He later coined the term " stress ", which has been accepted into the lexicon of most other languages. Selye conceptualized the physiology of stress as having two components: a set of responses which he called the " general adaptation syndrome ", and the development of a pathological state from ongoing, unrelieved stress.

Hans Selye

Selye discovered and documented that stress differs from other physical responses in that stress is stressful whether one receives good or bad news, whether the impulse is positive or negative. He called negative stress " distress " and positive stress " eustress ".

The system whereby the body copes with stress, the hypothalamic-pituitary-adrenal axis HPA axis system, was also first described by Selye. He also pointed to an "alarm state", a "resistance state", and an "exhaustion state", largely referring to glandular states. Later he developed the idea of two "reservoirs" of stress resistance, or alternatively stress energy. Feb 09, Gerard Bakker rated it it was amazing. It is very interesting for those with a background in medicine and biology.

The book provides an insight in the development of medical thought, even though that was not its aim when it was written 60 years ago. Also, Selye tries to erect an actual scientific model of the body and disease. Even though some of his findings are invalidated by newer science, it is an interesting proposal.

And something that even the current state of medical science isnt able to come up with. If one isnt well versed in It is very interesting for those with a background in medicine and biology.

Still the later chapters are interesting and very non technical. Oct 12, Andrew rated it it was amazing. Mar 01, Mariam rated it really liked it.

It took me a while to finish this book. I am not sure why it took me this long because I actually enjoyed every single bit of it. Selye recited everything down from the very thing that started him on his year stress journey to the scientific details of the journey laid in a very professional but simplified manner for everyone to read to the very personal implication of the concept he discovered not just on society but on himself as well.

See a Problem?

He even shared how his concept was attacked and he di It took me a while to finish this book. He even shared how his concept was attacked and he did not ridicule those who criticized his theory but he admitted that those people were of major positive influence to his work. It is quite rare to find such graceful attitude from a scientist towards the criticism of his colleagues and teachers.

One of the strengths of this book is that Selye mapped out the book in such a way that it is possible to skim quickly through all the scientific details if someone is not interested very much in understanding the technical work involved and get to what exactly the reader wants to find or extract from this book.

I could go on and on about how great this book is. I do know, however, that for me, that I will be coming back to this book again and again. Jul 20, Dr. Rae Baum rated it it was amazing. A classic to read, and re-read!!!
