WebThe induction of major histocompatibility complex (MHC) class II proteins by interferon gamma (IFN-γ) in macrophages play an important role during immune responses. Here we explore the signaling pathways involved in the induction by IFN-γ of the MHC II transactivator (CIIta) required for MHC II transcriptional activation. WebApr 10, 2024 · IFN-γ can upregulate the expression of IRF-1 by activating the JAK/STAT1 signaling pathway, which is a transcription factor for IL-7 [41,42]. Then, we hypothesized that the increased proliferative T cells would be mediated by IL-7, which would be regulated by IFN-γ produced by CD4 + Th1 cells after combination therapy.
