Unique biology of gliomas: challenges and opportunities.

abstract：:Patients suffering from severe depression often show an increased activity of the hypothalamic-pituitary-adrenocortical (HPA) system, a premature escape from the cortisol suppressant action of dexamethasone, and a number of other neuroendocrine changes. This might be explained by defective glucocorticoid feedback inhi...
