UNC93B1 mediates differential trafficking of endosomal TLRs
UNC93B1, a multipass transmembrane protein required for TLR3, TLR7, TLR9, TLR11, TLR12, and TLR13 function, controls trafficking of TLRs from the endoplasmic reticulum (ER) to endolysosomes. The mechanisms by which UNC93B1 mediates these regulatory effects remain unclear. Here, we demonstrate that UNC93B1 enters the secretory pathway and directly controls the packaging of TLRs into COPII vesicl...
متن کاملMouse model of MYD88L265P-dependent DLBCL.
The frequent detection of a highly recurrent, oncogenic, gain-of-function mutation that substitutes a leucine (L) residue at position 265 of the adapter protein myeloid differentiation primary response gene 88 (MYD88) with a proline (P) residue has implicated the mutant MYD88 allele in the natural history and clinical outcome of an important subset of diffuse DLBCL. However, a genetically engin...
متن کاملPrimary development and participation in a foreign antigen-driven immune response of a chromatin-reactive B cell clonotype are not influenced by TLR9 or other MyD88-dependent TLRs.
Recent findings support a central role for TLRs in both foreign Ag-driven immune responses and systemic autoimmune diseases mediated by B lymphocytes. In vitro studies have shown that the Ag receptors (BCRs) on B cells specific for nuclear autoantigens can facilitate the delivery of these autoantigens to the endocytic compartment, resulting in activation of the nucleic acid-specific TLRs presen...
متن کاملCutting edge: the UNC93B1 tyrosine-based motif regulates trafficking and TLR responses via separate mechanisms.
Sensing of nucleic acids by TLRs is crucial in the host defense against viruses and bacteria. Unc-93 homolog B1 (UNC93B1) regulates the trafficking of nucleic acid-sensing TLRs from the endoplasmic reticulum to endolysosomes, where the TLRs encounter their respective ligands and become activated. In this article, we show that a carboxyl-terminal tyrosine-based sorting motif (YxxΦ) in UNC93B1 di...
متن کاملInterleukins adapt to parasites
TLR choreography Pathogen-sensing Toll-like receptors (TLRs) must be deployed accurately. Here, Fukui et al. show how finely tuned these receptors are. Tweaking a single amino acid in a TLR-trafficking molecule determined whether the signal was green or red for nucleic acid–sensing TLRs (page 1339). TLR7 and TLR9 recognize viral nucleic acids—RNA and DNA, respectively—in endolysosomes. By seque...
