Metabolic Regulation by PPARγ Is Required for IL-33-Mediated Activation of ILC2s in Lung and Adipose Tissue

Scientists found that the metabolic sensor peroxisome proliferator-activated receptor gamma was highly expressed in ILC2s of the lung and adipose tissue and increased responsiveness to IL-33.

Early Emergence of T Central Memory Precursors Programs Clonal Dominance During Chronic Viral Infection

By mapping the long-term development of CD8+ T cell families derived from single naive precursors, scientists found that fate decisions made during the acute phase of murine cytomegalovirus infection could alter the level of memory inflation by more than 1,000-fold.
