Our major research interest at the Centre for Neuroendocrinology is in the neuroendocrinology of stress.
Current research focuses on two major areas. First, understanding the complex regulation of the adrenal medullary chromaffin cell, specifically how it regulates its secretory output of catecholamines and peptides in response to multiple stress-activated inputs. Much recent work has been directed at understanding how cytokines interact with this stress response.
Our second major interest concerns the role of another cytokine, prolactin, on the stress axis. Specifically we are interested in how stressors alter prolactin secretion from the pituitary and what role this prolactin then plays in stress adaptation under different physiological states.

Impaired or inappropriate adaptation to stress contributes to many major disease states.
