c-Fos is a component of transcription factor AP-1. We show that macrophages lacking c-Fos exhibit enhanced production of proinflammatory cytokines, potentiated NF-kappaB phosphorylation, and increased cell death following Salmonella enterica serovar Typhimurium infection. Furthermore, mice lacking c-Fos are highly susceptible to infection, suggesting that c-Fos confers resistance to Salmonella infection in mice.
c-Fos是转录因子AP-1的一个组成部分。我们发现,缺乏c-Fos的巨噬细胞在感染鼠伤寒沙门氏菌后,促炎细胞因子的产生增加、NF-κB磷酸化增强且细胞死亡增加。此外,缺乏c-Fos的小鼠对感染高度敏感,这表明c-Fos赋予小鼠对沙门氏菌感染的抵抗力。
