Adhesive interactions between integrin receptors and the extracellular matrix (ECM) are intimately involved in regulating development of a variety of tissues within the organism. In the present study, we have investigated the relationships between beta(1) integrin receptors and focal adhesion associated proteins during eye development. We used specific antibodies to examine the distribution of ...
pneumococcal autolysins are enzymes involved in cell wall turnover and cellular division physiologically. they have been found to be involved in the pneumococcus pathogenesis. the aim of this study was to identify the autolytic activity of spr1754 as a novel protein of streptococcus pneumoniae . moreover, the binding of the recombinant protein to plasma proteins was also determined. the spr1754...
Propionibacterium freudenreichii is a beneficial bacterium traditionally used as a cheese ripening starter and more recently for its probiotic abilities based on the release of beneficial metabolites. In addition to these metabolites (short-chain fatty acids, vitamins, and bifidogenic factor), P. freudenreichii revealed an immunomodulatory effect confirmed in vivo by the ability to protect mice...
Ca(2+)-dependent cell-cell adhesion is regulated by the cadherin family of cell adhesion proteins. Cadherins form trans-interactions on opposing cell surfaces which result in weak cell-cell adhesion. Stronger cell-cell adhesion occurs by clustering of cadherins and through changes in the organization of the actin cytoskeleton. Although cadherins were thought to bind directly to the actin cytosk...
Mast cells are inflammatory and immunoregulatory cells resident in tissues. They develop from bone marrow-derived progenitor cells that enter the tissue through the blood circulation. The specific localization and migration of mast cells in tissues is dependent on their interaction with extracellular matrix (ECM) proteins. Adhesion of human mast cells isolated from intestinal mucosa and culture...
Cell adhesion plays a central role in multicellular organisms helping to maintain their integrity and homeostasis. This complex process involves many different types of adhesion proteins, and synergetic behavior of these proteins during cell adhesion is frequently observed in experiments. A well-known example is the cooperation of rolling and stationary adhesion proteins during the leukocytes e...
The murine monoclonal antibodies TURP-27 and HNK-1 have been shown to detect antigens which are heavily expressed by benign prostatic hyperplasia and carcinoma of the prostate. Western blot analysis of prostate extracts showed that monoclonal antibodies TURP-27 and HNK-1 bound glycoproteins with molecular weights of 180,000,140,000, 120,000,100,000,90,000, and 69,000. Studies have shown that th...
One of the most exciting discoveries in biological adhesion is the recent and counter-intuitive observation that the lifetimes of some biological adhesive bonds, called catch bonds, are enhanced by tensile mechanical force. At least two types of adhesive proteins have been shown to form catch bonds--blood proteins called selectins and a bacterial protein called FimH. Both mediate shear-enhanced...
Chondroadherin (the 36-kD protein) is a leucine-rich, cartilage matrix protein known to mediate adhesion of isolated chondrocytes. In the present study we investigated cell surface proteins involved in the interaction of cells with chondroadherin in cell adhesion and by affinity purification. Adhesion of bovine articular chondrocytes to chondroadherin-coated dishes was dependent on Mg2+ or Mn2+...
Eukaryotic cells adhere to extracellular matrix during the normal development of organism, forming static adhesion as well cell motility. We study this process by considering a simplified coarse-grained model vesicle that has uniform energy with flat substrate, mobile-curved membrane proteins and active forces. find high concentration curved alone increases spreading vesicle, self-organization ...
