objective(s):to examine the expressions of cd11a, cd11b, and cd11c integrins in the myocardial tissues of rats with isoproterenol-induced myocardial hypertrophy. this study also provided morphological data to investigate the signal transduction mechanisms of myocardial hypertrophy and reverse it. materials and methods: a myocardial hypertrophy model was established by subcutaneously injecting i...

Our previous study showed that the cross-linking of very late antigen (VLA)/beta1 with anti-CD29 monoclonal antibody (MoAb), or interactions with extracellular matrix (ECM) proteins through VLA/beta1, failed to induce T-cell costimulation via the CD3/T cell receptor (TCR) pathway for over 1 year after allogeneic bone marrow transplantation (allo-BMT), although normal CD29 and CD3 expression was...

Our previous study showed that the cross-linking of very without the stimulation through VLA/b1 integrin. The high late antigen (VLA)/b1 with anti-CD29 monoclonal antibody tyrosine phosphorylation pattern gradually disappeared and (MoAb), or interactions with extracellular matrix (ECM) proit was finally returned to normal tyrosine phosphorylation teins through VLA/b1, failed to induce T-cell co...

The focus of this study is the characterization of human T cell blood-brain barrier migration and corresponding molecular trafficking signatures. We examined peripheral blood and cerebrospinal fluid immune cells from patients under long-term anti-very late antigen-4 (VLA-4)/natalizumab therapy (LTNT) and from CNS specimens. LTNT patients' cerebrospinal fluid T cells exhibited healthy central-/e...

To identify the mechanisms that cause monocyte localization in infarcted myocardium, we studied the impact of ischemia-reperfusion injury on the surface expression and function of the monocyte fibronectin (FN) receptor VLA-5 (alpha(5)beta(1) integrin, CD49e/CD29). Myocardial infarction was associated with the release of FN fragments into cardiac extracellular fluids. Incubating monocytes with p...

there is some evidence supporting the reduced activity of integrins following chronic administration of morphine. this reduction might play a role in morphine tolerance development. manganese binds to the extracellular domain of integrins and makes them to be activated. the effect of integrins activation using manganese on tolerance development to the analgesic effect of morphine was investigat...

A new channel assignment algorithm, called the Viterbi-like algorithm (VLA), is proposed to solve the channel assignment problem in cellular radio networks. The basic idea of the proposed algorithm is step-by-step (sequential) channel assignment with the objectives of minimum bandwidth required at every step, subject to adjacent channel and cochannel separation constraints. The VLA provides the...

Abstract The bladder undergoes large shape changes as it fills and empties experiences complex mechanical forces. These forces become abnormal in diseases of the lower urinary tract such overactive bladder, neurogenic retention. As primary mechanosensors linking actin cytoskeleton to extracellular matrix (ECM), integrins are likely play vital roles maintaining smooth muscle (BSM) homeostasis. I...

Epithelial to Mesenchymal Transition The cover image shows that the malignant cells generated by epithelial-mesenchymal transition (EMT) are breaking away from benign ones and spreading elsewhere. In article number 2106498, using single-particle tracking of β1-integrins labelled with fluorescent quantum dots, Yan Wei, Peng-Ye Wang, Hui Li, co-workers discover a significantly enhanced diffusion ...

Human fibronectin receptor (VLA-5) alpha and beta chain probes were used to identify their mouse homologues in a thioglycollate-elicited peritoneal exudate cell cDNA library. Sequence analysis of both alpha and beta chain-related murine clones revealed approximately 90% homology to their human counterparts by both nucleotide and derived amino acid sequence comparisons. Detectable alpha chain tr...
