Multi-omics unveils strain-specific neuroactive metabolite production linked to inflammation modulation by Bacteroides and their extracellular vesicles by Basit Yousuf, Walid Mottawea, Galal Ali Esmail, Nazila Nazemof, Nour Elhouda Bouhlel, Emmanuel Njoku, Yingxi Li, Xu Zhang, Zoran Minic, Riadh Hammami

“…Additionally, extracellular vesicles (EVs) produced by Bacteroides harbor multiple neuroactive metabolites, mainly GABA, and related key enzymes. We used CRISPR/Cas12a-based gene engineering to create a knockout mutant lacking the glutamate decarboxylase gene (gadB) to demonstrate the specific contribution of Bacteroides finegoldii-derived GABA in modulating intestinal homeostasis. …”

An oligodendrocyte silencer element underlies the pathogenic impact of lamin B1 structural variants by Bruce Nmezi, Guillermo Rodriguez Bey, Talia DeFrancesco Oranburg, Kseniia Dudnyk, Santana M. Lardo, Nathan Herdman, Anastasia Jacko, Sandy Rubio, Emanuel Loeza-Alcocer, Julia Kofler, Dongkyeong Kim, Julia Rankin, Emma Kivuva, Nicholas Gutowski, Katherine Schon, Jelle van den Ameele, Patrick F. Chinnery, Sérgio B. Sousa, Filipe Palavra, Camilo Toro, Filippo Pinto e Vairo, Jonas Saute, Lisa Pan, Murad Alturkustani, Robert Hammond, Francois Gros-Louis, Michael S. Gold, Yungki Park, Geneviève Bernard, Raili Raininko, Jian Zhou, Sarah J. Hainer, Quasar S. Padiath

“…Utilizing data from recently identified families that carry LMNB1 gene duplications but do not exhibit demyelination, ADLD patient tissues, CRISPR edited cell lines and mouse models, we have identified a silencer element that is lost in ADLD patients and that specifically targets expression to oligodendrocytes. …”
