Fasl induced apoptosis
WebApr 14, 2004 · Fas ligand- (FasL) mediated apoptosis is an important element of tissue-specific organ damage. We have developed biologically active small exocyclic peptide mimetics that disable apoptotic functions of Fas. The most effective mimetic binds to both its receptor and FasL with comparable affinity. WebJul 13, 2024 · The Fas and DR5 signaling pathways were necessary for TCR-induced CART cell apoptosis, as shown by the significant rescue of CART cells in spleen and liver upon systemic treatment with the cocktail of recombinant Fas-Fc and DR5-Fc proteins (Fig. 1f ).

WebFas pathway can also be regulated at the transcriptional level, such as by the tumor suppressor p53. p53 positively regulates genes, including Fas and Bax, that are involved … WebExpressed FasL increases activity of caspases and induces cell death. Although AGE increases the amount of reactive oxygen intermediate, accompanying cell death is not …
WebFeb 1, 2005 · As a consequence, they are insensitive to FAS-induced apoptosis when soluble FASL or an agonistic anti-FAS monoclonal antibody is added to the cells. However, upon incubation with NK cells, RMA-S tumor cells express FAS. RMA-S cells explanted from tumors growing in vivo also express FAS ( Screpanti et al., 2001 ). WebFeb 15, 2005 · Physiologic regulation of immune responses by Fas/FasL-induced apoptosis. (A) Activation of T cells by the engagement of T-cell receptors (TCR) with the peptide/major histocompatibility complex (MHC) bimolecular complex in conjunction with the transduction of secondary signals (not shown) leads to the up-regulation of both Fas and …
WebFas-induced apoptosis is important in the removal of cancer cells by cytotoxic T cells and NK cells which express FasL. DcR3 blocking of this cytotoxicity may enable some tumors to escape this cytotoxic attack. Quantitative PCR from genomic DNA has been used to show elevated DcR3 gene copy number in some primary tumors, including lung and colon. WebAug 7, 2013 · To examine whether blocking Fas/FasL activation can prevent Phe-induced apoptosis, neurons were pre-incubated with a neutralizing antibody against Fas for 2 h and then treated with Phe. The anti-Fas antibody significantly decreased both the number of apoptotic cells ( Fig. 4A ) and the expression levels of cleaved caspase-8 and cleaved …
