This started in 2019 as daydreamy PhD student musings with Tatsuya Araki. We're as excited as ever about germinal centers as a platform for experimental evolution. Many thanks to PIs @victora.bsky.social @matsen.bsky.social, co-1st authors Ashni Vora and Tatsuya, and many other key collaborators!

Read our latest preprint. A window into GC clonal evolution upon boost.

Happy to share our latest preprint on the clonal dynamics of GC “refueling.” We asked what happens at the clonal level after the simple (and ubiquitous) step of delivering a second vaccine dose during an ongoing GC response. www.biorxiv.org/content/10.6...

One more trick pulled off by antibody-mediated feedback www.cell.com/immunity/ful...

I am excited to share that our work, in which we have dissected the signals driven by the nucleoside-modified mRNA and LNP components of mRNA vaccines that regulate germinal center (GC) responses, is now published in Cell! www.cell.com/cell/fulltex...

Check out our latest preprint on the effects of antibody-mediated feedback on ongoing germinal center reactions, led by Alex Barbulescu and @janabilanovic.bsky.social www.biorxiv.org/content/10.1...

I'm stoked to have this long-term and highly collaborative effort out in the wild. We present an experimental evolution system to quantitatively study the rapid evolutionary dynamics of B-cell affinity maturation. These evolutionary mechanisms underpin antibody responses and immune memory formation.

Wanted to highlight our latest preprint--a huge effort by multiple people and labs, but led primarily by @wsdewitt.github.io, Tatsuya Araki, and Ashni Vora, in a very close wet-dry collaboration with @matsen.bsky.social’s lab at the Hutch www.biorxiv.org/content/10.1...

Happy #DayofImmunology! Congrats @ramadhenni.bsky.social & Alexandra Carey Hoppé it's out (finally!) @cp-cell.bsky.social! Incredibly grateful to co-leads @mlmunier.bsky.social, Vanessa Venturi & Tony Kelleher & all brilliant folks @garvaninstitute.bsky.social & Kirby Inst. for fantastic collab! 🧵

Hi, we are looking for two motivated postdocs to join our group! job-boards.greenhouse.io/chanzuckerbe... job-boards.greenhouse.io/chanzuckerbe...

How can B cells rapidly proliferate and have mutations suppressed? A longstanding mystery solved involving transient mutation suppression capability of germinal centers nature.com/articles/s41... www.nature.com/articles/s41...

New imaging from @victora.bsky.social's lab reveals a built-in safeguard that allows B cell populations to rapidly expand in germinal centers without introducing deleterious mutations. #RockefellerScience

Check out our last pub. from @mfgrp.bsky.social al lab! We discovered that skin commensal microbes induce systemic and local B cell responses upon colonization and took advantage of this knowledge to create topical vaccines using engineered skin microbes. Please read the thread for details.

Today we report that an engineered skin bacterium, swabbed gently on the head of a mouse, can unleash a potent antibody response against a pathogen. Could lead to topical vaccines that are applied in a cream. @djenetbousbaine.bsky.social led the charge... @natureportfolio.bsky.social 1/55

I’ve tried to put together a starter pack of immunologists/scientists exploring B Cell Repertoires and Antibody Affinities. Please feel free to share/join! go.bsky.app/4P64DmM
