Leukocyte Extravasation - Leukocyte Adhesion Deficiency

Leukocyte Adhesion Deficiency

Leukocyte adhesion deficiency (LAD) is a genetic disease associated with a defect in the leukocyte extravasation process, caused by a defective integrin β2 chain (found in LFA-1 and Mac-1). This impairs the ability of the leukocytes to stop and undergo diapedesis. People with LAD suffer from recurrent bacterial infections and impaired wound healing. Neutrophilia is a hallmark of LAD.
