The Nox2 NADPH oxidase regulates neutrophilic inflammation in the oral cavity

Shunying Jin, Richa A. Singhal, Jianzhu Luo, Yasmine H. Higgins, Kelley N Cooper, Marina Terekhova, Katherine Carey, Audrey F. Duff, Maxim N. Artyomov, Venkatakrishna Rao Jala, Rachel A. Idol, Michael T. Bailey, Mary C. Dinauer, Richard John Lamont, Juhi Bagaitkar

This study shows that Nox2 oxidase regulates neutrophilic inflammation in the oral cavity through Nrf2-dependent mechanisms, independent of its antimicrobial role.

Tyrosine phosphorylation coupling of one carbon metabolism and virulence in an endogenous pathogen

Kendall S. Stocke, Satya Deo Pandey, Shunying Jin, John D. Perpich, Lan Yakoumatos, Hirofumi Kosaki, Daniel Wade Wilkey, Zackary R. Fitzsimonds, Aruna Vashishta, Ian Snider, Mukesh K. Sriwastva, Hong Li, Jiu‐Zhen Jin, Daniel P. Miller, Michael L. Merchant, , Richard John Lamont

This study shows that tyrosine phosphorylation regulates the coupling between one carbon metabolism and virulence in Porphyromonas gingivalis by controlling gingipain protease localization and activity.

Episymbiotic Saccharibacteria suppresses epithelial immunoactivation through Type IV pili and TLR2 dependent endocytosis

Deepak Chouhan, Alex S. Grossman, Kristopher A. Kerns, Kendall S. Stocke, Maya Kim, Pu‐Ting Dong, Ajay Kumar, Lei Lei, Richard John Lamont, Jeffrey S. McLean, Xuesong He, Batbileg Bor

This study shows Saccharibacteria suppress epithelial immune activation by clustering TLR2 via Type IV pili and endocytosis, reducing cytokine signaling and enabling long-term persistence in the oral microbiome.
