General description
丝氨酸蛋白酶的不可逆抑制剂。其作用机理类似于氟磷酸二异丙酯。PMSF引起活性位点丝氨酸残基的磺酰化。还报告抑制未成熟胸腺细胞中的核小体间DNA片段化。有关更稳定的相关抑制剂，请参见AEBSF（目录号101500）。

Adipose triacylglycerol lipase (ATGL) is a dynamic lipid droplet-associated protein involved in cellular lipolysis, which is conserved from bacteria to humans. Recent methods that measure the enzymatic activity of ATGL in vitro are established using lipid emulsions. However, the lipid

Gastric CD4+T cells contribute to Helicobacter pylori (H. pylori)-induced gastritis by amplifying mucosal inflammation and exacerbating mucosal injuries. However, the pathogenic CD4+ T cell subset involved in gastritis and the potential regulators are still unclear. Here we identified an IL-21-producing
