Résumé
Nous montrons dans cet article que l’expression des récepteurs de l’angiotensine dans le cerveau est modulée lors d’un stress systémique ou psychologique. Cette plasticité a des caractéristiques distinctes selon la nature de l’agent stresseur, et pourrait contribuer à la genèse des réponses physiologiques compensatoires visant à maintenir l’intégrité de l’organisme.
Summary
In this short review, we hypothesize that the central renin-angiotensin system might participate to the initiation of compensatory responses to a stressor agent. Regulation of the expression of the brain angiotensin receptors might constitute a primary molecular mechanism by which this protecting action would take place. We illustrate this possibility by investigating the expression of the angiotensin type 1 receptor in the hypothalamus in response to systemic and neurogenic stressors.
