Carbohydrate ligand engagement with CD11b enhances differentiation of tumor-associated myeloid cells for immunotherapy of solid cancers by Mei Zhang, Veronique Roche, Victor Sandoval, Claire Wolford, Zachary Senders, Julian Anthony Kim, Susan Pereira Ribeiro, Alex Yicheng Huang, Rafick-Pierre Sekaly, Joshua Lyons

“…Importantly, we observed that the BG34-200-CD11b engagement triggered endocytosis of the binding complexes in TAIMs, which induced intracellular F-actin cytoskeletal rearrangement, effective phagocytosis, and intrinsic ICAM-1 (intercellular adhesion molecule I) clustering. …”

Development of a Recombinant Fusion Vaccine Candidate Against Lethal <i>Clostridium botulinum</i> Neurotoxin Types A and B by Eun-Sun Choi, Seong-Wook Pyo, So-Hyeon Kim, Jun-Ho Jeon, Gi-Eun Rhie, Mi-Ran Yun, Hwajung Yi, Yoon-Seok Chung

“…The HC_C domain is critical for binding to neuronal cell membrane receptors and facilitating BoNT internalization via endocytosis. Accordingly, it may serve as a vaccine candidate, inducing anti-BoNT-neutralizing antibodies in animals. …”

Gαi1/3 signaling mediates IL-5-induced eosinophil activation and type 2 inflammation in eosinophilic chronic rhinosinusitis by Huanxia Xie, Jiang Ji, Zhichen Liu, Ning Lu, Yuqian Wei, Aina Zhou, Jisheng Liu, Qingqing Jiao, Qingqing Jiao

“…In EoL-1 cells, Gαi1/3 was associated with IL-5-activated IL-5Rα, promoting IL-5Rα endocytosis and transducing downstream signaling. IL-5-induced EoL-1 cell proliferation and degranulation were suppressed after Gαi1/3 silencing. …”

Tumor CEMIP drives immune evasion of colorectal cancer via MHC-I internalization and degradation by Ying Zhu, Jiao Li, Tao Zhang, Lei Zhao, Min Jin, Jinghua Ren, Jing Tang, Haihong Wang, Zhenyu Lin, Qing Liang, Ruiqi Li, Biying Zhang, Qingling Hua, Guojie Xu, Jiayuan Chen, Lanqing Wang, Dejun Zhang, Dandan Yu

“…Mechanistically, CEMIP acted as an adaptor for the interaction betweenMHC-I and clathrin, which drove MHC-I internalization via clathrin-dependent endocytosis. Furthermore, CEMIP anchored internalized MHC-I to lysosomes for degradation, disrupting the recycling of MHC-I to the cell surface.Conclusion Overall, our study unveils a novel regulatory mechanism of MHC-I on tumor cell surfaces by CEMIP-mediated internalization and degradation. …”
