Retrospective data on the pituitary gland response during immune and neoplastic processes

A synthesis of many experimental works performed during the last ten years regarding the nonspecific response of the pituitary gland during some immune and neoplastic processes is presented. Different modalities of the response of pituitary gland cell that vary depending on the antigen type were observed. The TAB vaccine inducing a humoral immune response determined an increased secretory activity of STH and FSH cells which are involved by their secretions in the activation of protein synthesis also including antibodies. The tumoral antigens also representing a stressing factor brought about a more intense activity besides the FSH cells, the ACTH and TSH cells.
