Abstract

Vitamin D is a steroid hormone synthesized in the skin, which is involved in many physiological processes (homeostasis of phosphorus and calcium, modulation of the immune system) and pathological (autoimmune diseases such as type 1 diabetes mellitus). This disease is characterized by destruction of beta cells through the action of pancreatic B lymphocytes, macrophages, T cells, CD4 + and CD8 + T cells that culminates in slow, progressive loss of insulin secretion. Studies have been demonstrated that vitamin D stimulates phagocytosis of the bacteria by macrophages as well as production of interleukin (IL)-1 and prostaglandin (PG)-E2. The aim of this work is to study the relationship between vitamin D supplementation, the expression of the vitamin D receptor (VDR - Western blotting) of peritoneal lavage macrophages (LP) and bronchoalveolar lavage (BAL) and the immune response in diabetic mice (alloxan 60 mg / kg, iv) and healthy. Thus, this project aims to expand the knowledge of the action of vitamin D in immunity, thereby improving the quality of life of diabetic patients, allowing better control of the disease, since this hormone replacement therapy is easy to perform and inexpensive.
