Thwarting dyskinesia by targeting mTORC1.

abstract：:Cross-linking of proteins by mammalian transglutaminases (TGs) plays important roles in physiological phenomena such as blood coagulation and skin formation. We show that Drosophila TG suppressed innate immune signaling in the gut. RNA interference (RNAi) directed against TG reduced the life span of flies reared under...

abstract：:Insulin receptor substrate 2 (IRS2) is an adaptor protein that becomes tyrosine-phosphorylated in response to the cytokines interleukin-4 (IL-4) and IL-13, which results in activation of the phosphoinositide 3-kinase (PI3K)-Akt pathway. IL-4 and IL-13 contribute to allergic lung inflammation. To examine the role of IR...
