CD18


Also found in: Wikipedia.

CD18

a type I transmembrane protein found on lymphocytes, neutrophils, monocytes, macrophages, some B cells, dendritic cells, and natural killer cells that appears active in signal transduction; expressed in some patients with B-cell chronic lymphocytic leukemia, most with acute nonlymphocytic leukemia, and some with hairy cell leukemia.

CD18

This term is generally preferred by immunologists; the preferred HUGO symbol for the gene is ITGB2, see there.

Leukocyte Adhesion Deficiency-I (LAD-I) is a rare, autosomal recessive pediatric disease caused by a mutation of the ITGB2 gene that encodes for the Beta-2 Integrin component CD18. CD18 is a key protein that facilitates leukocyte adhesion and enables their extravasation from blood vessels to combat infections.

Leukocyte adhesion deficiency (LAD) is a rare primary immunodeficiency disorder with autosomal recessive inheritance which is characterized by presence of a defect of phagocytic function resulting from a lack of leukocyte cell surface expression of b2 integrin molecules (CD11 and CD18) that are essential for chemotaxis.

The subunit coded by [beta]2 (CD18) is a typical leukocyte marker (e.g., also on microglia), and also the absence of [alpha]6 in NCCs is consistent with other findings, e.g., in the chicken a6 expression is downregulated at the onset of NCC migration and re-expressed upon neuronal differentiation (Bronner-Fraser et al., 1992; Testaz et al., 1999).
