So we blocked IFNγ in Mtb infected macaques and….the animals were fine. Turns out mice overestimate the importance of IFNγ in TB because IFNγ drives iNOS in mice but not macaques or humans. This means we don’t actually know how T cells suppress Mtb. rdcu.be/ff9GB #tuberculosis #immunology

📣Huge preprint 🔔 Today we share something our group has been working toward for a long time, led by @lucasmoriniere.bsky.social We asked can we predict which receptor a phage targets from its genome sequence alone? For most phages, we couldn’t. So Lucas set out to do something I had only dreamed of.
