Nkt activation

The best-known subset of CD1d-dependent NKT cells expresses an invariant T-cell receptor (TCR) α chain. These are referred to as type I or invariant NKT cells (iNKT) cells. They are notable for their ability to respond rapidly to danger signals and pro-inflammatory cytokines. Once activated, they engage in effector functions, like NK transactivation, T cell activation and differentiation, B cell activation, dendritic cell activation and cross-presentation activity, and macrop… WebbActivated NKT cells secrete interferon-γ, kill tumor cells in a CD1d-dependent manner, and suppress tumor growth in the liver. Inhibition of conversion from primary to secondary bile acid via administration of vancomycin can induce NKT cell recruitment and suppress tumor growth, which can be reversed by oral supplementation with secondary bile acid. …

Anti-PD-1 therapy enhanced the expression of activating molecules CD69, NKp46, and NKG2D in NKT cells of the tumor and spleen. This therapy activated NKT cells directly and indirectly via DCs. Activated NKT cells acquired tumoricidic properties directly, by secreting perforin, and indirectly by stimulating M1 macrophages polarization. Webb11 apr. 2024 · Abstract. During chronic hepatitis B virus (HBV) infection, hepatic fibrosis is a serious pathological condition caused by virus-induced liver damage.

WebbWe found that the incorporation of the synthetic NKT activating glycolipid α-galactosylceramide (α-GC) into rBCG-SIV gag significantly enhanced CD8 + T cell responses against an immunodominant Gag epitope, compared to responses primed by unmodified rBCG-SIV gag. Webb2 maj 2005 · Activation of NKT cells by α-GalCer in vivo leads to rapid release of cytokines and activation of other immune effectors. Recent studies in mice suggest that α-GalCer–mediated NKT activation can provide an adjuvant function, and enhance T cell immunity to coadministered antigen, which is mediated by induction of DC maturation …

Webb14 apr. 2024 · This approach induces adjuvant effects by combining NKT cell activation with delivery of tumor antigen to DCs in vivo. In addition to linking innate and adaptive immunity, aAVC therapy can lead to efficient trafficking of specific anti-tumor CD8 + T cells to the tumor site and also the formation of long-term memory T cells. WebbNKT cells in mice, Nieuwenhuis et al. [38] reported that activation of NKT cells in vivo induced macrophage-mediated clearance of Pseudomonas aeruginosa from lung. Although they did not provide evidence that V §14 NKT cells could respond directly to the pathogen, this may be the case with the activation observed after infec-
