Leukocyte adhesion--a fundamental process in leukocyte physiology.
Leukocyte adhesion is of pivotal functional importance. The adhesion involves several different adhesion molecules, the most important of which are the leukocyte beta 2-integrins (CD11/CD18), the intercellular adhesion molecules, and the selectins. We and others have extensively studied the specificity and binding sites in the integrins and the intercellular adhesion molecules for their recepto...
متن کاملNeutrophil Adhesion in Leukocyte Adhesion
We have previously reported a newly discovered congenital disorder of neutrophil adhesion, leukocyte adhesion deficiency syndrome type 2 (LAD II). The clinical manifestations of this syndrome are similar to those seen in the classic leukocyte adhesion deficiency syndrome, now designated type 1 (LAD I), but the two syndromes differ in the molecular basis of their adhesion defects. LAD I is cause...
متن کاملLeukocyte Adhesion Deficiency Type 1 Presenting as Leukemoid Reaction
The hallmarks of leukocyte adhesion deficiency (LAD) are defects in the leukocyte adhesion process, marked leukocytosis and recurrent infections. These molecular and clinical manifestations result from an impaired step in the inflammatory process, namely, the emigration of leukocytes from the blood vessels to sites of infection, which requires adhesion of leukocytes to the endothelium. Over las...
متن کاملLeukocyte adhesion defect.
Leukocyte adhesion defect (LAD) is a rare, autosomal recessive primary immunodeficiency disorder of phagocytes, in which there is defective aggregation at the site of infection due to the absence of surface integrins. Diagnosis is based primarily on flowcytometric analysis of neutrophils for the surface expression of CD11, CD18 and CD15s. We describe here a case of a 7-months-old boy who presen...
متن کاملPeriodontal Involvement in Leukocyte Adhesion Deficiency: Review of the Literature and a Case Report
Objective: Leukocyte adhesion deficiency(LAD) is a scarce, autosomal recessive inherited disorder . LAD-I which is the most common type occurs due to mutations on the CD18 gene. This mutation leads to absence or severe reduction of leukocyte cell surface expression of ß2 integrin molecules which are necessary for the adhesion of the leukocytes to the endothelial cells, transendothelial mi...
