Great work, Karthi @KarthikeyaniC and Melanie @dr_ohsopretty! Check out our collaborative work with the Rabinowitz lab in Cell Metabolism about NAD precursors in the gut microbiome. @Cell_Metabolism

Chellappa et al. show that the gut microbiome primarily obtains its NAD from host-derived circulating nicotinamide. Deamidation of nicotinamide to nicotinic acid by microbes maintains circulating...

We had a blast writing this mini-review on the recent discovery of the mito-NAD transporter in mammalian cells, & what it could mean for the broader field of NAD biology. @alexjbott @Yeyunouyang @giuliosf @KoryLab @timluongo @e_girardi @TrendsBiochem
