There is increasing evidence that the alterations of function and/or level of adhesion molecules play a key role in the pathogenesis of autoimmune diseases, such as Graves' disease or type 1 diabetes. The aim of the present study was to evaluate the expression of lymphocyte function-associated antigen 1 alpha (LFA-1 alpha, CD11a) and L-selectin (CD62L) molecules on peripheral mononuclear cells in Graves disease and type 1 diabetes in comparison to healthy controls, since they were shown to play an important role in lymphocytes and/or monocytes migration into the organs affected by immune process and are suggested to contribute to the pathogenesis of Graves disease and type 1 diabetes. The percentages of monocytes/lymphocytes expressing LFA-1 alpha antigen and lymphocytes expressing L-selectin antigen and the fluorescence intensity of the studied molecules were measured by flow cytometry. At the onset of both autoimmune diseases the percentage of highly CD11a positive lymphocytes and the mean fluorescence intensity were statistically higher than in the healthy controls and patients with Graves' disease after thyreostatic therapy. The fluorescence intensity of LFA-1 alpha on monocytes was also increased in type 1 diabetic patients, but not in Graves' disease. The analysis of CD62L antigen expression on peripheral blood lymphocytes revealed decreased percentages of L-selectin positive cells in patients with Graves' disease (before and after treatment) and insulin-dependent diabetes in comparison to the controls. Our study suggests that the alterations of the expression of CD11a and/or CD62L molecules on peripheral blood lymphocytes could be the markers of ongoing autoimmune process in Graves disease and type 1 diabetes.

UI	MeSH Term	Description	Entries
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D003922	Diabetes Mellitus, Type 1	A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.

D006111	Graves Disease	A common form of hyperthyroidism with a diffuse hyperplastic GOITER. It is an autoimmune disorder that produces antibodies against the THYROID STIMULATING HORMONE RECEPTOR. These autoantibodies activate the TSH receptor, thereby stimulating the THYROID GLAND and hypersecretion of THYROID HORMONES. These autoantibodies can also affect the eyes (GRAVES OPHTHALMOPATHY) and the skin (Graves dermopathy).

D016169	Lymphocyte Function-Associated Antigen-1	An integrin heterodimer widely expressed on cells of hematopoietic origin. CD11A ANTIGEN comprises the alpha chain and the CD18 antigen (CD18 ANTIGENS) the beta chain. Lymphocyte function-associated antigen-1 is a major receptor of T-CELLS; B-CELLS; and GRANULOCYTES. It mediates the leukocyte adhesion reactions underlying cytolytic conjugate formation, helper T-cell interactions, and antibody-dependent killing by NATURAL KILLER CELLS and granulocytes. Intracellular adhesion molecule-1 has been defined as a ligand for lymphocyte function-associated antigen-1.

D018845	CD11 Antigens	A group of three different integrin alpha chains (CD11a, CD11b, CD11c) that are associated with an invariant integrin beta-2 chain (CD18 ANTIGENS).
