Mass spectrometry analysis of proteins interacting with Fbxw7 in T cells


ABSTRACT: To elucidate how gut microbiota (GM) downregulated Fbxw7, we treated CD4+ T cells with GM-lysates and pulled down Fbxw7 in the cell lysates. Then, the precipitated proteins were analyzed by mass spectrometry, and eight E3 ligases were revealed to interact with Fbxw7.

Segmented filamentous bacteria are essential for intestinal T helper 17 (Th17) cell induction, but their colonization in the adult intestine is controversial. Therefore, whether there are gut microbiota (GMs) that mediate Th17 cell generation in humans of different ages is elusive. Here, we reported that colonization of ubiquitous Alcaligenes faecalis was sufficient to induce intestinal Th17 cells. Alcaligenes faecalis proteins were endocytosed by CD4<sup>+</sup> T cells in a manner dependent on  ...[more]
