Fc-null anti-CTLA-4 antibody: a novel strategy to facilitate cancer immunotherapy by ridding the colitis-inducing mishap.

Writing recently in Science, Lo and coworkers characterized a critical role of the gut microbiota in CTLA-4 blockade-induced colitis, revealing that an Fc domain deficient anti-CTLA-4 antibody can elicit antitumor responses effectively while avoiding the induction of colitis-like disease.1 This research opens up novel avenues for employing anti-CTLA-4 antibody therapy to circumvent the onset of colitis, which is often considered the Achilles' heel of what is arguably the most efficacious treatment for certain blood cancers and/or solid tumors.

Gastrodin ameliorates acute pancreatitis by modulating macrophage inflammation cascade via inhibition the p38/NF-κB pathway.

Direct effect of protein kinase A on four putative phosphorylation sites of aquaporin 2 in vitro.

The water channel aquaporin 2 (AQP2) has four phosphorylation sites at Ser256, Ser261, Ser264, and Ser269 in the C-terminus and these sites are important for AQP2 bioactivity.

Atypical hemolytic uremic syndrome induced by CblC subtype of methylmalonic academia: A case report and literature review.

Rationale: Methylmalonic acidemia (MMA) is a common organic acidemia, mainly due to methylmalonyl-CoA mutase (MCM) or its coenzyme cobalamin (VitB12) metabolic disorders.

Synthesis of Au-SiO2 Composite Nanospheres and Their Catalytic Activity.

We report a simple and environmentally friendly approach to the synthesis of Au-SiC2 composite nanospheres.
