Activation of lysophagy by a TBK1-SCFFBXO3-TMEM192-TAX1BP1 axis in response to lysosomal damage by Na Yeon Park, Doo Sin Jo, Jae-Yoon Yang, Ji-Eun Bae, Joon Bum Kim, Yong Hwan Kim, Seong Hyun Kim, Pansoo Kim, Dong-Seok Lee, Tamotsu Yoshimori, Eun-Kyeong Jo, Eunbyul Yeom, Dong-Hyung Cho

“…We also identify TAX1BP1 as a critical autophagic adaptor that recognizes ubiquitinated TMEM192 during lysophagy and find that TBK1 activation is crucial for lysophagy, as it phosphorylates FBXO3 in response to lysosomal damage. Knockout of FBXO3 significantly impairs lysophagy, and its reconstitution with a loss-of-function mutant (V221I) further confirms its essential role in lysophagy regulation. …”

MAPK4 inhibits the early aberrant activation of B cells in rheumatoid arthritis by promoting the IRF4-SHIP1 signaling pathway by Pei Huang, Guangli Yang, Pingping Zhang, Yin Zhu, Yaning Guan, Jian Sun, Qian Li, Yang An, Xiaoqi Shi, Juanjuan Zhao, Chaohong Liu, Zhixu He, Yan Chen, Zuochen Du

“…In this study, we identified a significant reduction in MAPK4 expression in both RA patients and collagen-induced arthritis (CIA) mouse models, which correlates with disrupted B cell activation. Using MAPK4 knockout (KO) mice, we demonstrated that MAPK4 intrinsically promotes the differentiation of marginal zone (MZ) B cells. …”
