Abstract
Pituitary-specific transcription factor 1 (PIT-1; POU domain, class 1, transcription factor 1 (POU1F1)) is an essential transcription factor for the differentiation of somatotrophs, lactotrophs, and thyrotrophs, and for the expression of growth hormone (GH), prolactin (PRL), and thyroid-stimulating hormone (TSH). Mutations in PIT-1 cause congenital defects in GH and PRL secretion and severe TSH insufficiency. Anti-PIT-1 antibody syndrome, firstly reported in 2011, is characterized by acquired GH, PRL, and TSH deficiencies without PIT-1 mutation and is associated with the presence of the circulating antibody against PIT-1 protein as a marker. Various autoantibodies are detected with multiple endocrine organopathies in this syndrome; therefore, it meets the criteria of autoimmune polyglandular syndrome. Mechanistically, cytotoxic T lymphocytes specifically reacting with PIT-1 protein play an important role in the development of this syndrome.
期刊介绍：
A series of integrated overviews on cutting-edge topics
New sophisticated technologies and methodological approaches in diagnostics and therapeutics have led to significant improvements in identifying and characterizing an increasing number of medical conditions, which is particularly true for all aspects of endocrine and metabolic dysfunctions. Novel insights in endocrine physiology and pathophysiology allow for new perspectives in clinical management and thus lead to the development of molecular, personalized treatments. In view of this, the active interplay between basic scientists and clinicians has become fundamental, both to provide patients with the most appropriate care and to advance future research.
