The Rap1-RIAM Pathway Regulates the Expression of Integrins αEβ7(CD103) and α4β7, Which Guide T Cell Homing to Intestinal Compartments

contribution of setting to the study of characters and the main idea in e. brontes: wuthering heights and t. hardys: return of the native.

this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...

IL-7 induces expression and activation of integrin α4β7 promoting naive T-cell homing to the intestinal mucosa.

Interleukin-7 (IL-7) is a nonredundant cytokine that plays a critical role in T-cell homeostasis and promotes immunologic reconstitution in lymphopenic hosts. Here, we show that IL-7, at doses that reflect suprahomeostatic concentrations achieved in lymphopenic hosts, is a potent and selective inducer of the gut-homing integrin α4β7 in human T cells, as documented both ex vivo and in vivo in pa...

Control of α4β7 Integrin Expression and CD4 T Cell Homing by the β1 Integrin Subunit

The WAVE2 complex regulates T cell receptor signaling to integrins via Abl- and CrkL–C3G-mediated activation of Rap1

WAVE2 regulates T cell receptor (TCR)-stimulated actin cytoskeletal dynamics leading to both integrin clustering and affinity maturation. Although WAVE2 mediates integrin affinity maturation by recruiting vinculin and talin to the immunological synapse in an Arp2/3-dependent manner, the mechanism by which it regulates integrin clustering is unclear. We show that the Abl tyrosine kinase associat...

a synchronic and diachronic approach to the change route of address terms in the two recent centuries of persian language

terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...
