Gasdermin

Definition / 释义

gasdermin(常指 gasdermin family,气皮素/气德明蛋白家族):一类在免疫与炎症反应中起关键作用的蛋白质家族,典型功能是在细胞膜上形成孔洞,从而促进细胞发生焦亡(pyroptosis)并释放炎症因子(如 IL1β)。

Pronunciation / 发音

/sdrmn/

Examples / 例句

Gasdermin D forms pores in the cell membrane during pyroptosis.
Gasdermin D 在焦亡过程中会在细胞膜上形成孔洞。

Researchers found that blocking gasdermin activation can reduce excessive inflammation in some disease models.
研究人员发现,在某些疾病模型中抑制 gasdermin 的激活可以减轻过度炎症反应。

Etymology / 词源

Gasdermin 是生物医学命名中的新词,通常解释为由 “gas-”(常被理解为与 gastrointestinal 胃肠相关的缩写/来源)与 “-dermin”(与 dermis 皮肤相关)组合而来,反映该家族早期研究中与胃肠道和皮肤组织表达/表型有关的背景;后续研究则将其功能核心定位为膜孔形成与炎症性细胞死亡
