Homeostatic cytokines
WebHsp60 expression was found to be enhanced in response to cytokines as diverse as IL-1beta, TNF-alpha, IL-4, IL-6 and IL-10. Upregulation of hsp27, however, was primarily induced by immunoregulatory cytokines like IL-4, IL-6 and TGF-beta whereas alphaB-crystallin expression was found to be enhanced by the pro-inflammatory cytokine TNF … WebDescription: Cytokines are intracellular messengers that activate multiple signaling pathways and regulate cell survival, differentiation, migration, apoptosis and immune responses. We are investigating the homeostatic control of cytokine-mediated cell signaling using interleukin-4 (IL-4) as a model cytokine.

Web10 jul. 2001 · To investigate the role of cytokines, we have devised an approach for studying homeostatic proliferation in excised lymphoid organs (LOs) cultured in vitro. Of the various cytokines tested, only IL-4, IL-7, and IL-15 had the capacity to enhance homeostatic proliferation of naïve CD8+cells in vitro. Web3 okt. 2005 · Surprisingly, enhanced antitumor efficacy and autoimmunity was caused by increased function rather than increased numbers of tumor-reactive T cells, as would be expected by homeostatic mechanisms. The γC cytokines IL-7 and IL-15 were required for augmenting T cell functionality and antitumor activity.
WebHomeostasis of T cells can be defined as the ability of the immune system to maintain normal T-cell counts and to restore T-cell numbers following T-cell depletion or expansion. These processes are governed by extrinsic signals, most notably cytokines.
Web23 apr. 2010 · Several lines of evidence support a role for the integrin α4β7 and its ligand MAdCAM-1 in mediating homing of lymphocytes to the gut, since MAdCAM-1 is expressed on intestinal lamina propria venules. 6 First, β7-deficient mice have severely impaired formation of their gut-associated lymphoid tissue throughout the gastrointestinal tract, … Web4 apr. 2024 · The spontaneous peripheral proliferation of mature T cells relies on the support of homeostatic cytokines as well as allogeneic antigens encountered in the host. In the model, both spontaneous peripheral proliferations of donor-derived Teff and Treg cells are considered to be autocatalytic with rate constants a E and a R.
Web1 apr. 2024 · For example, boosting homeostatic cytokines in the intratumoral environment might be achievable by using bispecific therapeutic approaches such as IL-7 or IL-15 tethered to a tumor Ag-directed mAb. Such an approach may help to maintain sufficient survival signals to sustain an expanded population and effectively keep the pressure on …
