Gut Microbiota and Derived Metabolites Mediate Obstructive Sleep Apnea Induced Atherosclerosis

Jin Xue, Celeste Allaband, Simone Zuffa, Orit Poulsen, Jason D. Meadows, Dan Zhou, Pieter C. Dorrestein, Rob D. Knight, Gabriel George Haddad

This study shows that gut microbiota and their metabolites contribute to OSA-induced atherosclerosis, particularly in the aorta, through specific bacterial imbalances and bile acid dysregulation.

Non cell-autonomous effect of astrocytes on cerebral cavernous malformations

Miguel Alejandro Lopez‐Ramirez, Shady Ibrahim Soliman, Preston Hale, Catherine Chinhchu Lai, Angela Pham, Esau J. Estrada, Sara McCurdy, Romuald Girard, Riya Verma, Thomas Moore, Rhonda Lightle, Nicholas Hobson, Robert Shenkar, Orit Poulsen, Gabriel George Haddad, , Mark H. Ginsberg

The paper shows that astrocytes contribute to cerebral cavernous malformations (CCMs) through VEGF production driven by endothelial NO, highlighting non-cell-autonomous mechanisms.
