Abstract IFNγ is considered the primary mediator of adaptive immunity to Mycobacterium tuberculosis (Mtb) infection. In mice, control of Mtb requires IFNγ. In humans, IFNγ is critical for resistance to infection with non-tuberculous mycobacteria (NTM), but its relative requirement for control of pulmonary tuberculosis (TB) is less clear. Here we block IFNγR1 signaling in macaques at different times following Mtb infection.

Keywords: Th1 cell responses complement complosome C5aR2 prostaglandin prostacyclin IL-1β Crohn’s disease rheumatoid arthritis cryopyrin-associated periodic fever syndrome CAPS Introduction Timely contraction of successful T helper 1 (Th1) cell responses, characterized by the downregulation of interferon (IFN)-γ production and co-expression of the anti-inflammatory cytokine interleukin-10 (IL-10), is essential in limiting Th1 cell-driven tissue pathologies1 and preventing autoimmune disease.2...

Abstract Type-1 and type-3 interferons (IFNs) are important for control of viral replication; however, less is known about the role of Type-2 IFN (IFNγ) in anti-viral immunity. We previously observed that lung infection with Mycobacterium bovis BCG achieved though intravenous (iv) administration provides strong protection against SARS-CoV-2 in mice yet drives low levels of type-1 IFNs but robust IFNγ.
