Adhesion molecules are critical for leukocytes migration to the skin. Leukocytes must first be captured or tethered from the flowing blood allowing them to roll along the skin vessels. Leukocytes are activated by chemoattractants, which results in firm adhesion and arrest and ultimately transendothelial migration into the tissue. Selectin family which consists of L-selectin, P-selectin, E-selectin is critical for capture and rolling. Deficiency of these molecules leads to the diminution of cutaneous inflammation. Firm adhesion is governed by β2 integrin and α4 integrin. Inhibition of β2 integrin and its ligand ICAM-1 also reduce cutaneous inflammation. Similarly, blocking of α4 integrin and its ligand VCAM-1 alleviate inflammation of the skin. Transmigration and diapedesis are mediated by various molecules such as PECAM-1, CD99, and JAM, whose inhibition also leads to amelioration of skin inflammation. Manipulating adhesion molecules might lead to novel therapy to treat dermatitis by controlling leukocytes migration into cutaneous sites of inflammation.

D015815 Cell Adhesion Molecules Surface ligands, usually glycoproteins, that mediate cell-to-cell adhesion. Their functions include the assembly and interconnection of various vertebrate systems, as well as maintenance of tissue integration, wound healing, morphogenic movements, cellular migrations, and metastasis.

D016023 Integrins A family of transmembrane glycoproteins (MEMBRANE GLYCOPROTEINS) consisting of noncovalent heterodimers. They interact with a wide variety of ligands including EXTRACELLULAR MATRIX PROTEINS; COMPLEMENT, and other cells, while their intracellular domains interact with the CYTOSKELETON. The integrins consist of at least three identified families: the cytoadhesin receptors (RECEPTORS, CYTOADHESIN), the leukocyte adhesion receptors (RECEPTORS, LEUKOCYTE ADHESION), and the VERY LATE ANTIGEN RECEPTORS. Each family contains a common beta-subunit (INTEGRIN BETA CHAINS) combined with one or more distinct alpha-subunits (INTEGRIN ALPHA CHAINS). These receptors participate in cell-matrix and cell-cell adhesion in many physiologically important processes, including embryological development; HEMOSTASIS; THROMBOSIS; WOUND HEALING; immune and nonimmune defense mechanisms; and oncogenic transformation. Integrin

D019087 Selectins Transmembrane proteins consisting of a lectin-like domain, an epidermal growth factor-like domain, and a variable number of domains that are homologous to complement regulatory proteins. They are important cell adhesion molecules which help LEUKOCYTES attach to VASCULAR ENDOTHELIUM. Selectin
