LAD1 occurs due to defects in CD18, a critical protein that makes up the LFA-1 and MAC-1 integrins. Defects in these integrins then impair the ability of leukocytes to stick or adhere to the walls of blood vessels. Ultimately, this failure of adhesion leads to failure of migration, leading.

Abstract. Leukocyte adhesion deficiency type 1 (LAD-1) is a rare, inherited immunodeficiency that affects one per million people yearly and usually presents with recurrent, indolent bacterial infections of the skin, mouth, and respiratory tract and impaired pus formation and wound healing The leukocyte adhesion deficiency (LAD) syndromes are primary immunodeficiency disorders that are classified as defects in adhesion-dependent functions of myeloid phagocytes, principally polymorphonuclear leukocytes (PMNs; neutrophils) and monocytes . Although rare (≤1 : 1 000 000 births), their investigation has yielded fundamental insights. Leukocyte adhesion deficiency is a rare inherited immunodeficiency which develops because a group of immune cells called phagocytes fail to bind to the blood vessel wall, and therefore cannot get to the site of inflammation or tissue injury.. Normally, phagocytes, which are mostly neutrophils, circulate in the blood waiting for a signal that something's wrong somewhere in the body
