2022年2月18日 · GBP1 identifies gram-negative bacteria such as the enteric pathogen, Salmonella enterica serovar Typhimurium, that enter the cytoplasm of the host cell. GBP1 then quickly connects to LPS and stimulates the assembly of more GBPs in the order of GBP2, GBP3, and GBP4. Subsequently, inflammatory caspase-4 arrives at the GBP1–4 activation platform.

2019年7月1日 · Here we report that Toxoplasma-induced death of human macrophages requires GBP1 and its ability to target Toxoplasma parasitophorous vacuoles through its GTPase activity and prenylation. Mechanistically, GBP1 promoted Toxoplasma detection by AIM2, which induced GSDMD-independent, ASC-, and caspase-8-dependent apoptosis.
