WebFeb 24, 2024 · Here, we discover that T cell-derived interferon (IFN)γ in combination with arachidonic acid (AA) induces immunogenic tumor ferroptosis, serving as a mode of action for CD8 + T cell (CTL)-mediated tumor killing. Web1 day ago · Many of the findings of this study may hold true in the context of cancer as well. For instance, cancer-associated fibroblasts can cross-present antigens to CD8 + cells, while simultaneously suppressing CD8 + T cell immunity and restricting T cell tumor entry. 9.

WebIFN-γ is a glycosylated protein of 25 kDa that is produced by NK cells and by type 1 CD4 and CD8 T cells (immune IFN). Although IFN-γ induces antiviral activity, it is structurally unrelated to IFN-α/β and uses a distinct receptor. However, IFN-γ shares some components of the intracellular signaling pathways for type 1 IFN.
