Autophagy is a key degradative pathway coordinated by external cues, including
starvation, oxidative stress, or pathogen detection. Rare are the molecules known
to contribute mechanistically to the regulation of autophagy and expressed
specifically in particular environmental contexts or in distinct cell types.
Here, we unravel the role of RUN and FYVE domain-containing protein 4 (RUFY4) as
a positive molecular regulator of macroautophagy in primary dendritic cells
(DCs). We show that exposure to interleukin-4 (IL-4) during DC differentiation
enhances autophagy flux through mTORC1 regulation and RUFY4 induction, which in
turn actively promote LC3 degradation, Syntaxin 17-positive autophagosome
formation, and lysosome tethering. Enhanced autophagy boosts endogenous antigen
presentation by MHC II and allows host control of Brucella abortus replication in
IL-4-treated DCs and in RUFY4-expressing cells. RUFY4 is therefore the first
molecule characterized to date that promotes autophagy and influences endosome
dynamics in a subset of immune cells.
