Dr. Sarah Holton from @UWMedicine is the recipient of a K23 award to support her efforts to define the immune cell populations that lead to progression of fibrosis in Interstitial Lung Disease. Congratulations Dr. Holton! bit.ly/4g0cHq4

It's that time of year again! Have you published an insightful paper about microbiome science as a post-doc? Think you can explain it clearly in 1000 words or fewer? You should enter the Science/Noster Microbiome Prize competition - science.org/content/page/n…

Ok, also going to try something new - hoping for the science engagement of old - @harrison-lab.bsky.social

@LakliHurathu Thanks Lakmali! Awesome seeing you!

Join our team at the NIH to explore immune cell interactions in the CNS and meninges! We are investigating molecular pathways that drive neuroinflammation and neurodegenerative diseases. #PostDocJobs #ScienceJobs #NeuroImmunology drive.google.com/file/d/1kCiwjw…

@rohamparsa @czbiohub Congrats Roham! Looking forward to seeing the cool science that comes from your lab!

I’m very happy to announce that I’ll soon become a Principal Investigator and Group Leader at the Chan Zuckerberg Biohub in New York (@czbiohub)! I’m really looking forward to this new chapter in my life and I’m incredibly excited to get things moving in the lab. #CZBiohubNY🧵1/

@CarlaTheNove Honestly, before the summary statement it’s more painful, after the summary statement it’s less!

@PhilipAhern @d_bayik Honestly we throw it all in at once, i.e. we have Fc block in our staining cocktail because 1) it’s higher affinity and 2) we save 30 mins, we throw the live dead in there too, and it works great. And personally I think our staining looks just fine 👍🏻

@d_bayik Yeah, I can't see any situation where it hurts, so I think we may just start keeping it in too.

Another flow question. I was taught to Fc block cells, remove Fc block, & stain. But I see lots of people keep the Fc block in during the staining too. The latter makes sense (staining ab. could displace Fc), but is there a reason the former is advisable? Does it actually matter?

@Caroline_Bartma @DrYihuiShen Maybe Doreen Cantrell?

🎉#JI_TopRead ➡️ This study by @LorantAlina et al. @cstefani06 @adamlacyhulbert @BRIseattle investigates the role of integrins in the regulation of responses by plasmacytoid DCs. Check it out now! #ReadTheJI #immunology ow.ly/Kicz50Sh1cj

Antigen-level resolution of commensal-specific B cell responses can be enabled by phage display screening coupled with B cell tetramers dlvr.it/T883df

🦠 @BRIseattle scientists have created a high-throughput approach that enables researchers to conduct antigen-level studies of the immune system’s interactions with the intestinal microbiome. Abstract: bit.ly/4bVL7HI Press release: bit.ly/3XcT1YR

@AiingLim Oh me too!

@harrison_oj Thank you so much Ollie my bay-mate😊 Looking forward to collaborating again!

First of many awards and much fantastic science to come! Congrats @AiingLim!!

Congratulations to Dr. John O’Shea, NIAMS Scientific Director, for being formally inducted into the National Academy of Sciences! This designation – one of the highest honors a scientist can achieve – recognizes distinguished and continuing achievements in original research.

@jakob_moltke @gabebarron @TBillipp Congratulations @jakob_moltke @TBillipp, great to see this in its final form, and out in the wild. Well done!

The final version of @TBillipp's graduate school work is now published! Tyler uncovered an epithelium-intrinsic response unit that couples tuft cell sensing of the lumen to Cl-/fluid secretion from neighboring enterocytes cell.com/immunity/fullt…

@LionakisLab @sheenamverma30 @BRIseattle @ImmunityCP Cheers Mihalis!

@harrison_oj @sheenamverma30 @BRIseattle @ImmunityCP many kudos, mate!

Today, I am delighted to share @SheenamVerma30’s work, and the ^ first paper ^ from the Harrison Lab @BRISeattle, published in @ImmunityCP -cell.com/immunity/fullt… (1/16)

@ArnonGroup Thanks Tal! And there’s nothing better than a good pun - excellent work!

This one is definitely a ‘Phage’ turner! @harrison_oj lab used phage display screening to identify antigen-specific BCRs in mLN and PPs & used tetramer stain to track these cells! A much-needed advance in the field to fish specific B cell clones and study them in depth #Immunity
