... initially thought to be solely located in the cytoplasm are increasingly being found on the surface of bacterial cells. Adhesion to host epithelia and extracellular matrices, recruitment and activation of plasminogen and modulation of host immune responses are some of the alternative functions exhibited...

... review, I summarize and discuss the present investigations of biofilm-forming archaeal species, i.e. their diverse biofilm architectures in monospecies or mixed communities, the identified EPSs (extracellular polymeric substances), archaeal structures mediating surface adhesion or cell–cell connections...

... responses and can be regulated through the formation of multimolecular complexes. Tetraspanins as facilitators and building blocks of specialized microdomains may be involved in this process. In the present study, we demonstrated that, in contrast with previous reports, integrin-mediated adhesion did...

... recurrences of urinary tract infections compared with women without diabetes. Type 1 fimbriae are the most important virulence factors used not only for adhesion of E. coli in the urinary tract, but also for the colonization by E. coli in patients with Crohn's disease or ulcerative colitis. It appears...

... through epithelium to monitor mucosal tissues and microenvironments. A number of adhesion molecules are known to regulate transmigration of leucocytes through epithelial and endothelial layers. Paracellular and transcellular leucocyte transmigration are regulated by adhesion molecules such as PECAM-1...

...Srabasti J. Chakravorty; Katie R. Hughes; Alister G. Craig Cytoadherence of PRBCs ( Plasmodium falciparum -infected red blood cells) to host endothelium has been associated with pathology in severe malaria, but, despite extensive information on the primary processes involved in the adhesive...

..., the mechanisms by which synovial fibroblasts influence leucocyte recruitment remain poorly understood. We recently demonstrated that synovial fibroblasts from RA patients were capable of activating co-cultured endothelial cells so that they supported capture and adhesion of flowing neutrophils in vitro [ 10...

... interactions links the intracellular environment through cell-surface receptors to multimolecular extracellular assemblies. These interactions not only control the behaviour of individual cells, but also determine tissue architecture. Adhesion receptor function is partly determined by an ability to tether...

... that integrins form physical complexes at the cell membrane with growth factor receptors, giving rise to signalling platforms at the adhesive sites. It is probable that at these sites integrins regulate adhesion and at the same time physically constrain and direct the response to soluble growth factors towards...

.... However, based on in vitro studies using wortmannin and LY294002, there is evidence for an important role for PI 3-kinases in regulating a broad range of functional platelet responses, including primary platelet adhesion, cytoskeletal remodelling and platelet aggregation. One of the critical platelet...

...M.J. Humphries The integrins are a family of α,β heterodimeric receptors that mediate dynamic linkages between extracellular adhesion molecules and the intracellular actin cytoskeleton. Integrins are expressed by all multicellular animals, but their diversity varies widely among species...
