Here, we define an endothelial cell (EC) lumen signaling complex involving Cdc42, Par6b, Par3, junction adhesion molecule (Jam)-B and Jam-C, membrane type 1-matrix metalloproteinase (MT1-MMP), and integrin alpha(2)beta(1), which coassociate to control human EC tubulogenesis in 3D collagen matrices. Blockade of both Jam-B and Jam-C using antibodies, siRNA, or dominant-negative mutants completely...

Background: Hemodialysis is a process of removing waste and excess fluid from blood when kidneys cannot function efficiently. It often involves diverting blood to the filter of the dialysis machin to be cleared of toxic substances. Fouling of pores in dialysis membrane caused by adhesion of plasma protein and other toxins will reduce the efficacy of the filtre.Objective: In This study, the infl...

Formation of axonal pathways involves a variety of molecules that influence cell-cell interactions. The polysialic acid (PSA) moiety of the neural cell adhesion molecule (NCAM) is present on neuronal surfaces during process outgrowth. Our studies reveal that the removal of PSA causes a decrease in the rate of elongation of retinal cell processes on a substrate of neuronal membranes derived from...

The I domain of lymphocyte function-associated antigen (LFA)-1 contains an intercellular adhesion molecule (ICAM)-1 and ICAM-3 binding site, but the relationship of this site to regulated adhesion is unknown. To study the adhesive properties of the LFA-1 I domain, we stably expressed a GPI-anchored form of this I domain (I-GPI) on the surface of baby hamster kidney cells. I-GPI cells bound solu...

In the present study, variation among different bacterial strains was observed in the plaques of tobacco chewers (TC) as compared to those from normal persons (non tobacco chewers) (NTC). Bacterial strain J1 (dominant in the plaques of NTC) did not initiate the process of adhesion (biofilm formation) until it appeared to have reached a required population density necessary for the production of...

The cell-cell and cell–basement membrane adhesion in the epidermis provides the skin with its resistance against environmental influences; epidermal integrity is required for protection of the entire organism against mechanical, physical, or microbial noxae. The major cellular structures involved are the desmosomes at cell-cell junctions in the epidermis and the hemidesmosome–basement membrane ...

background: inflammation is involved in development, progression, and complications of atherosclerotic disease. clinical studies have indicated that the level of monocyte chemoattractant protein 1 (mcp-1), il-18, and adhesion molecules correlates with the severity of atherosclerosis and can predict future cardiovascular events. experimental studies have shown pentoxifylline (ptx) reduces these ...
