Brucella suis ΔmapB outer membrane vesicles as an acellular vaccine against systemic and mucosal B. suis infection by Florencia Muñoz González, Florencia Muñoz González, Magali G. Bialer, Maria L. Cerutti, Silvia M. Estein, Lila Y. Ramis, Pablo C. Baldi, Pablo C. Baldi, Ángeles Zorreguieta, Ángeles Zorreguieta, Mariana C. Ferrero, Mariana C. Ferrero

“…Serum antibodies from both OMVs groups reduced B. suis adherence and invasion of lung epithelial cells and enhanced its phagocytosis by macrophages. Upon in vitro antigen stimulation, spleen cells from mice immunized with ΔmapB OMVs secreted higher levels of interleukin-17 and especially gamma interferon compared to cells from mice immunized with wt OMVs, suggesting the induction of a stronger T helper 1 response in the ΔmapB OMVs group. …”

Retinoblastoma-binding Protein 9 Suppresses Intestinal Inflammation and Inflammation-induced Tumorigenesis in MiceSummary by Kensuke Hamada, Yuki Nakanishi, Yu Muta, Mayuki Omatsu, Kosuke Iwane, Munehiro Ikeda, Jiayu Chen, Yoko Masui, Naoki Aoyama, Nobukazu Agatsuma, Go Yamakawa, Takahiro Utsumi, Hiroki Kitamoto, Makoto Okabe, Yoshiro Itatani, Takumi Adachi, Koubun Yasuda, Shuji Yamamoto, Akihisa Fukuda, Etsushi Kuroda, Masaki Ohmuraya, Kazutaka Obama, Seiichi Hirota, Hiroki Ikeuchi, Kenji Nakanishi, Hiroshi Seno

“…A positive feedback loop involving epithelial cell apoptosis, commensal microbiome invasion, and activation of submucosal immune activity was identified in Rbbp9-/- mouse intestines through enhanced JAK/STAT1 signaling in RBBP9-deficient epithelial cells and macrophages. The genetic inhibition of STAT1 or treatment with the JAK/STAT inhibitor reversed epithelial cell apoptosis and mitigated the enhanced susceptibility to DSS-induced colitis in Rbbp9-/- mice. …”

Single-cell multiomics reveal divergent effects of DNMT3A- and TET2-mutant clonal hematopoiesis in inflammatory response by Wazim Mohammed Ismail, Jenna A. Fernandez, Moritz Binder, Terra L. Lasho, Minsuk Kim, Susan M. Geyer, Amelia Mazzone, Christy M. Finke, Abhishek A. Mangaonkar, Jeong-Heon Lee, Liguo Wang, Kwan Hyun Kim, Vernadette A.

Wieben, Nicholas Chia, Alexandre Gaspar-Maia, Mrinal M. Patnaik

“…Using single-cell multiomics sequencing, we identify cell-specific gene expression changes associated with DNMT3A mutations, along with significant epigenomic deregulation affecting enhancer accessibility, resulting in overexpression of interleukin-32 (IL-32), a proinflammatory cytokine that can result in inflammasome activation in monocytes and macrophages. Finally, we show with single-cell resolution that the loss of function of DNMT3A is directly associated with increased chromatin accessibility in mutant cells. …”
