ENDOCRINOLOGY: Hormone deficiency is the pits
The pituitary is a gland at the base of the brain that produces a number of hormones that regulate growth, reproduction, and metabolism. PIT-1 is a gene that controls the expression of many of those hormones, including growth hormone (GH), prolactin (PRL), and thyroid-stimulating hormone (TSH). Human mutations in PIT-1 are linked to short stature and multiple hormone deficiency. In new research, Yukaka Takahashi and colleagues at Kobe University Graduate School of Medicine in Kobe, Japan, investigated several patients who exhibited normal growth but adult-onset deficiency of GH, PRL, and TSH. They found that although these patients did not have mutations in PIT-1, each had PIT-1specific antibodies in their blood. The researchers believe that these patients suffer from a unique autoimmune disorder that results in the immune system attacking PIT-1expressing cells in the pituitary.
