Web10 Aug 2015 · Th1-produced IFN-γ activates macrophages, enhances activity of cytotoxic T cells, mediates antiviral immune activity, and induces differentiation of naive T cells into Th1 cells. IFN-γ is also able to upregulate its own expression . The role of IFN-γ in development and persistence of CLE lesions is also supported by findings in transgenic ... WebStimulation of M1 macrophages results in high secretion levels of IL-1b, TNF-α, IL-12, IL-18, and IL-23. Moreover, the M1 macrophage phenotype has been shown to express high levels of major histocompatibility complex class II (MHC II), CD68, CD80, and CD86, as well as of the Th1 cell-attracting chemokines, including CXCL9 and CXCL12 [ 12 ].

WebThe interplay between macrophages and Th1 cytokines in COPD is well established. IFN-γ is the main cytokine responsible for the activation of macrophages, and the Th1/Tc1-associated chemokines are produced by macrophages. 38. The present study provides evidence for a Th1-dominated immune process, particularly through the CCR5 chemokine ... Web28 Nov 2014 · As an essential component of innate immunity, macrophages have multiple functions in both inhibiting or promoting cell proliferation and tissue repair. Diversity and plasticity are hallmarks of macrophages.
