IntroductionPrimary autoimmune hypophysitis (PAHs) is a rare inflammatory disease of the pituitary gland. Although largely investigated, the pathogenesis of PAH is not completely clarified. We aimed to investigate the immune response in PAHs.Material and methodsSerum anti-pituitary and anti-hypothalamus antibodies (respectively APAs and AHAs) were investigated though an indirect immunofluorescence on monkey h...

Introduction: Somatotropinomas are benign pituitary tumors with heterogeneous biological and clinical behavior. The tumor microenvironment (TME) is an environment generated by the interaction between tumor cells and the host immune system. It affects both the behavior of the tumor and the outcome of the therapy. The GNAS gene encodes the alpha subunit of G proteins associated with hormone receptors such as TSH, PTH, GHRH, FSH/lH, ACTH. Mutation of this gene has been associated...
