文献和实验A small molecule binding HMGB1 inhibits caspase-11-mediated lethality in sepsis.
Caspase-11, a cytosolic lipopolysaccharide (LPS) receptor, mediates lethal immune responses and coagulopathy in sepsis, a leading cause of death worldwide with limited therapeutic options. We previously showed that over-activation of caspase-11 is driven by hepatocyte-released high mobility group box 1 (HMGB1), which delivers extracellular LPS into the cytosol of host cells during sepsis. Using a phenotypic screening strategy with recombinant HMGB1 and peritoneal macrophages, we discovered that FeTPPS, a small molecule selectively inhibits HMGB1-mediated caspase-11 activation. The physical interaction between FeTPPS and HMGB1 disrupts the HMGB1-LPS binding and decreases the capacity of HMGB1 to induce lysosomal rupture, leading to the diminished cytosolic delivery of LPS. Treatment of FeTPPS significantly attenuates HMGB1- and caspase-11-mediated immune responses, organ damage, and lethality in endotoxemia and bacterial sepsis. These findings shed light on the development of HMGB1-targeting therapeutics for lethal immune disorders and might open a new avenue to treat sepsis.
一般-20度保存半年应该没问题 DMSO是无菌的啊 chenfengyiguo 关于PMA溶解分装的帖子好多,据我所知的包括园里和文献,有以下需要解决的问题: 1:PMA作为一种PKC激动剂,常用于THP-1或者U937细胞的诱导为巨噬细胞。分子量616.8 2:一般是买sigma的,1mg包装,使用浓度有100nm/L~160nm/L(指上述细胞),那么1mg可处理10L细胞(160nm/L),故一般买1mg包装就足够
实验91 聚丙烯酰胺凝胶电泳(PAGE) 原理 聚丙烯酰胺(polyacrylamide,PAA)凝胶是丙烯酰胺(acry—lamide,Acr),在交联剂甲叉双丙烯酰胺(bisacrylamide,Bis)的作用下经聚合而形成的一种大分子化合物。 Acr的聚合作用只有在自由基存在时才能发生,需要一个催化诱发剂系统产生自由基,过硫酸铵—TEMED(四甲基乙二胺)和核黄素—TEMED
