PKM2 promotes Th17 cell differentiation and autoimmune inflammation by fine-tuning STAT3 activation

2019

Th17 cells undergo metabolic reprogramming towards glycolysis to support their differentiation and pathogenicity. Damasceno et al. report that PKM2, a glycolytic enzyme, plays a nonmetabolic role in mediating Th17 cell differentiation and autoimmune neuroinflammation by fine-tuning STAT3 activation.

TLR4 abrogates the Th1 immune response through IRF1 and IFN-β to prevent immunopathology during L. infantum infection

2020

A striking feature of human visceral leishmaniasis (VL) is chronic inflammation in the spleen and liver, and VL patients present increased production levels of multiple inflammatory mediators, which contribute to tissue damage and disease severity. Here, we combined an experimental model with the transcriptional profile of human VL to demonstrate that the TLR4-IFN-β pathway regulates the chronic inflammatory process and is associated with the asymptomatic form of the disease. Tlr4-deficient mice harbored fewer parasites in their spleen and liver than wild-type mice. TLR4 deficiency enhanced the Th1 immune response against the parasite, which was correlated with an increased activation of de…
