Congratulations to newly minted Dr. S. Erandika Senvirathe on a successful PhD defense! Next, she'll head to a postdoc in Dr. Durga Singer's group at Univ. of Michigan, Ann Arbor.

Join us Friday, Jan. 16, 2026, for Erandika Senevirathne's Final Ph.D. Defense: "Steady-state phosphorylation of SHIP1 by Lyn restricts macrophage activation in the absence of a phagocytic synapse."
Advisor: Tanya Freedman(@tfreedmanlab.bsky.social),
9:00 am, 1-125 CCRB

Lyn expression in macrophages promotes TLR activation and restricts proliferation in an isoform-independent manner RNA sequencing and functional assays demonstrate that both LynA and LynB restrict macrophage proliferation and drive TLR-induced ECM remodeling and inflamm

New publication: "Lyn expression in macrophages promotes TLR activation and restricts proliferation in an isoform-independent manner" is out now in JLB. MD/PhD student Anders Lindstedt led with an assist from @lab-williams.bsky.social. academic.oup.com/jleukbio/art... @cfi-umn.bsky.social 🧪

Can we improve peer review? We think we can! Check out an experiment I helped with as part of @solvingforsci.bsky.social 's mission to make science better.
And if you don't want to read the whole bioRxiv manuscript, here's an overview of the main findings:

Just said goodbye to my NIH MIRA award. Really hurts to see the word “terminated” in writing. Even worse to see it next to the F31 awarded to a fantastic PhD student in my lab @aybv.bsky.social. I REFUSE to let this stop us!!!

Writing in solidarity. For whatever that's worth.

Steady-state phosphorylation of SHIP1 by Lyn restricts macrophage activation in the absence of a phagocytic synapse Microscale engagement of the hemi-ITAM-containing receptor Dectin-1 by a fungus-derived particle initiates signaling through the Src-family kinases (SFKs) and Syk that leads to downstream Erk and Akt ...

Preprint alert from the Freedman lab! PhD student Erandika Senevirathne reveals a unique role for the Src-family kinase Lyn in maintaining steady-state signaling in macrophages and a role for the phagocytic synapse in protecting against negative feedback by SHIP1. 🧪

Not nlm, but grant submissions/reviews and institute websites

The NIH eRA Commons website has been down all afternoon. Does anyone have insight on whether this is a glitch or a plan? 🧪

I think people both within science and outside science don’t fully appreciate the miracle that were the Covid-19 vaccines. How much courage it took to get the sequence out, how much work had already gone into figuring out the best viral antigen and how best to present it. 1/
