Conditioned medium of pinealocytes (CMP, 18-20%) added to primary cultures of rat pituitary cells for 1.5 h changed neither the basal rate of PRL secretion nor dopamine-inhibited release. However CMP markedly attenuated PRL secretion induced by thyroliberin or isobutyl-menthylxanthine. Besides CMP reduced basal PRL release during 18-h-incubation. The results obtained indicate possible involvement of the pineal gland in direct inhibitory control of PRL secretion in male rats.

Type 1 diabetes (T1D) is a complex disease driven by the immune system attacking the insulin-producing beta cells in the pancreas. Understanding the role of different T cell subpopulations in the development and progression of T1D is crucial. By employing flow cytometry to compare the characteristics of T cells, we can pinpoint potential indicators of treatment response or therapeutic inefficacy.
