In tumor cells , the treatment induces destructive autophagy and cy...

This review identifies protein lactylation as a transformative "metabolic translator" that converts high lactate levels in the tumor microenvironment into stable programs of cancer treatment resistance . The authors explain how this post-translational modification occurs through both enzymatic pathways, involving writers like AARS1/2 and KATs , and non-enzymatic processes driven by glycolytic bypr...

This scientific study investigates the protective role of the protein ANGPTL2 in managing rheumatoid arthritis (RA) by regulating immune cell behavior. The researchers discovered that a deficiency in ANGPTL2 accelerates joint destruction and inflammation by allowing macrophages to undergo pyroptosis , a form of inflammatory cell death. Mechanistically, ANGPTL2 maintains cellular health by interact...

Modern scientific research has overturned the traditional view of the brain as an isolated, "immune-privileged" organ, instead revealing it to be a dynamic immunological interface . Key discoveries such as the meningeal lymphatic vessels and the glymphatic system demonstrate that the central nervous system actively drains waste and communicates with the peripheral immune system. The blood-brain ba...
