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...

The surface microtexture of an orthopaedic device can regulate cellular adhesion, a process fundamental in the initiation of osteoinduction and osteogenesis. Advances in fabrication techniques have evolved to include the field of surface modification; in particular, nanotechnology has allowed for the development of experimental nanoscale substrates for investigation into cell nanofeature intera...

Objective—High-shear perfusion of blood over collagen results in rapid platelet adhesion, aggregation, and procoagulant activity. We studied regulation of 2 1 and IIb 3 integrin activation during thrombus formation on collagen. Methods and Results—Blockade of glycoprotein (GP) VI by 9O12 antibody or of P2Y purinergic receptors permitted platelet adhesion but reduced aggregate formation, fibrino...

Invasion and metastasis are aggressive cancer phenotypes that are highly related to the ability of cancer cells to degrade extracellular matrix (ECM). At the cellular level, specialized actin-rich structures called invadopodia mediate focal matrix degradation by serving as exocytic sites for ECM-degrading proteinases. Adhesion signaling is likely to be a critical regulatory input to invadopodia...
