Look who stopped by NYC from across the globe! Felt like worlds colliding having my PhD PI @elimelb.bsky.social and postdoc PI @karapedsgastrodoc.bsky.social in the same room. So fitting on Intl Day of Women&Girls in Science to celebrate two brilliant women who paved the way for me!

Happy holidays from the Margolis lab! Pic after a hard core karaoke party😂

👉 We generated a starter pack for #neurogastroenterology and enteric #neuroscience!

Let's connect and bring gut-brain research and clinical neurogastroenterology to the next level! 🌐

The Margolis Lab had a great time at #ANMS2025 in Minneapolis! Postdocs Sarah, Lin & Chalystha gave abstract talks, PRC Director Kara closed the conference, and we met Keynote Speaker & 2021 Nobel Laureate David Julius and his team! #ANMS225

PRC Highlight: #MargolisLab making strides again! Congrats to Chalystha Lee who received the 2025 ISSR Travel Award at the #ISSR2025 hosted in Vienna! With mentorship from Dr. Kara Margolis & Dr. Michael Gershon lighting the way. #mentorship #ISSR #womeninresearch @chalysthalee.bsky.social

Alt text (expanded version for web or accessibility-focused platforms): Vertical infographic titled “Why Gabapentin Works Differently for Different People.” Section 1 explains that 10% of adults live with neuropathic pain and gabapentin doesn't help everyone. Section 2 shows that researchers used donated human dorsal root ganglia (DRG) neurons to study gabapentin’s effects, combining electrophysiology and RNA sequencing. Section 3 illustrates how gabapentin reduced excitability in some donors’ neurons but not others, and those differences matched gene expression profiles. Section 4 highlights how this could lead to more personalized pain treatment that adds life to the years of people living with chronic pain. Footer credits the donors and includes the study DOI

Gabapentin is widely prescribed for nerve pain, but it doesn’t work the same for everyone.

We studied actual human sensory neurons from donors and found that some responded strongly - and others hardly at all.

Just back from a great week in Vienna for #ISSR2025. I am grateful for the travel award and the opportunity to share my work. Big thanks to @karapedsgastrodoc.bsky.social and Mike Gershon for their steady support in the lab and my career. Loved connecting with 5-HT researchers from around the world!

#ISSR2025

@karapedsgastrodoc.bsky.social gave a fantastic talk on the lab's important work on SSRI use in the gastrointestinal tract
@margolislabnyu.bsky.social highlighting @linyhung.bsky.social and @sarahanajjar.bsky.social 's work!
@nyupainresearch.bsky.social

Excited to learn about all things Serotonin / 5HT at #ISSR2025 in Vienna!

What do you think these #painresearch results from Ullrich et al. in Science Advances may mean for finding the patterns behind ligand bias? bit.ly/4elhYYE

And just like that, AMPIRS takes its final bow! 🎬Huge cheers to our grand finale presenters and a confetti cannon 🎉 of congrats to all the Flash Talk, Poster and Oral Presentation champs! 🏆 You dazzled, you delivered, you definitely deserve it! #PRCpride #MPBpride

Congratulations @tonelloraquel.bsky.social and @mariafialho.bsky.social !! Fantastic work!

Congratulations @sarahanajjar.bsky.social & @linyhung.bsky.social !! 🙌🥳

Aging and injury drive neuronal senescence in the dorsal root ganglia - Nature Neuroscience The authors describe a susceptibility of the peripheral nervous system to neuronal senescence with age or injury relevant for sensory dysfunction, such as chronic pain.

BOOM! www.nature.com/articles/s41... I think this is a big step forward for the field. Congrats to Lauren Donovan and @vivtawfik-mdphd.bsky.social and the whole Tawfik lab team.

I am looking for a postdoc with an immunology background interested in joining a Yale neuroscience lab to study how the brain controls immunity. At Yale, we have a wonderful interdisciplinary & collaborative #neuroimmune community. Please reach out or share with anyone who might be interested!

Meet our 2025 AGA Council section leaders Introducing the five members elected to join the AGA Institute Council and lead specialty-based sections.

Congrats to @karapedsgastrodoc.bsky.social on becoming part of the 2025 AGA Council section leaders!! Read more👉 gastro.org/news/meet-ou...

Definitely something important to consider wrt our studies in rodent preclinical models!

🔬 Exciting discovery! We've been curious about the function of unique IBA1+ cell staining we observed around healthy human DRG neurons in the lab (indicated by red arrows). A new paper @cellpress.bsky.social finally provides some answers. Link: www.cell.com/cell/fulltex...

Well done, Woo-Tae! 🙌

We have slots for 2-3 postbacs! Get in touch if you’re interested in joining the Affective Neuroscience and Pain lab & contributing to our studies of pain, emotion, and social processing in the 🧠
