Congrats to Dr. Melamed, the 1st @scripps.edu PhD student to join the lab! 🥂 #PhDone

@scripps.edu PhD candidate Dom Haas received the @societymucosalimm.bsky.social Young Investigator Award to present his work at #ICMI2026 👏

It was a pleasure to co-host @belkaidlab.bsky.social from @pasteur.fr with Shika Ramanan @salkinstitute.bsky.social. Great dinner conversation with @johntchang.bsky.social & Ananda Goldrath!

For @mikerobe.bsky.social, science is more than a search for answers—it’s a chance to guide others along the way. In a Q&A with Scripps Research Magazine, he shares how he mentors young scientists and studies innate immune cells that protect barrier tissues like skin and gut.

Antibiotic use in early life impairs MAIT cell–mediated immunity in adulthood, say Gabrielle LeBlanc, Adam Sobel, Michael Constantinides (@mikerobe.bsky.social) and colleagues @scripps.edu: rupress.org/jem/article/... #InfectiousDisease #HostDefense #MucosalImmunology #LymphocyteBiology #Microbiome

Research from Assoc. Prof. @mikerobe.bsky.social's lab identifies a probiotic-based solution to antibiotic-linked MAIT cell depletion. In preclinical models, pairing necessary antibiotics with a riboflavin-producing gut bacterium restored MAIT cell development during a key early-life window.

Study reveals high stakes of early immune development—and a potential probiotic fix

Excited to share research co-led by Gabby & Adam in @jem.org! Grateful to the NIH & @scripps.edu for support.

LeBlanc, Sobel, Constantinides et al. @scripps.edu show that antibiotic treatment in early life can deplete riboflavin-synthesizing commensals & impair #MAIT cell development, rendering adult animals more susceptible to bacterial #pneumonia. rupress.org/jem/article/... #Microbiome

Thankful for this talented group!

Nice to catch up with fellow @belkaidlab.bsky.social alum @michelenamorado.bsky.social in sunny San Diego!

Mini golf to celebrate my promotion to associate professor. Grateful to the past & present trainees that made this possible!

Our work co-led by @scripps.edu students Dominic & Jonathan shows that microbial tropism determines how metabolites are presented to #MAIT cells!

MAIT cell responses to intracellular and extracellular pathogens are mediated by distinct antigen presenting cells https://www.biorxiv.org/content/10.1101/2025.05.03.652000v1

Congrats to @scripps.edu PhD candidate Dom Haas, who was offered a Canada Graduate Scholarship, the highest doctoral award from NSERC! 🗡️🍾🥂
