RHBDL4 – A Novel Regulatory Mechanism for Controlling the Body’s Immune System

Toll-like receptor 4 (TLR4) is a central regulatory factor of innate immunity in the body, mainly able to recognize the lipopolysaccharide cell wall components of bacteria and induce cytokine release.   Recently, a research report titled “RHBDL4-triggered downregulation of COPII adaptor protein TMED7 suppresses TLR4-mediated inflammatory signaling” was published in Nature Communications. Scientists from institutions such as the University of Cologne found through their research that the membrane protease RHBDL4…

The Release of Special Inhibitory Pathways May Promote the Body’s Immune Response against HIV Infection

During antiretroviral therapy, the persistent presence of HIV-1 may be due to its establishment of a long-lived virus library in quiescent immune cells. Recently, an article titled “TGF-β blockade drives a transitional effector phenotype in T cells reversing SIV latency and decreasing SIV reservoirs in vivo” was published in the international journal Nature Communications. In the research report, scientists from institutions such as Northwestern University in the United States used…

Regulatory Mechanism of RAS Palmitoyltransferase

RAS participates in multiple signaling pathways, and post-translational modifications regulate the subcellular localization of RAS to regulate downstream signal transduction. Among them, palmitoylation is a necessary modification of HRAS and NRAS signal transduction. The acyltransferase DHHC9 binds to the helper protein GCP16 to catalyze palmitoylation of HRAS and NRAS, but the interaction between GCP16 and DHHC9, as well as the molecular mechanism by which GCP16 regulates the palmitoylation activity of…
