Due to the rapid development of antiretroviral therapy (ART), HIV patients can live longer than before. But even if it is a very effective long-term ART, the HIV virus remains stubbornly incurable, so patients need medication for life. Scientists have been convinced that this is because the HIV virus has created a stubborn virus-infected cell nest that allows HIV to survive indefinitely. A recent study done by researchers at Brigham…

PNAS: A Key Switch in Biological Clocks Found
Multipoint phosphorylation of the PERIOD 2 (PER2) protein is a critical step in determining the mammalian clock cycle. Previous studies have suggested that the phosphorylation of PER2 by casein kinase 1 (CK1) requires the initiation of an undiscovered protein kinase. CK1 is an essential circulatory protein that is highly conserved from algae to humans. These phosphorylation processes stabilize the PER2 and delay its degradation to extend the circadian clock cycle….
