Pat put an exceptional amount of work into this project over the past several years. The B cell immunology in the paper is a real tour de force.

Our exciting new HIV vaccine paper was published in Nature today. Thanks to Shane for the amazing opportunity to lead this study!

Excited to share our new Nature paper published today: Vaccination elicits HIV broadly neutralizing antibodies in primates www.nature.com/articles/s41... A project 14 years in the making with an outstanding team at @lji.bsky.social, @scrippsresearch.bsky.social and many collaborating institutions

Thanks Eric! I worked to make this review of human immune memory to vaccines comprehensive and accessible. And I made an accompanying video lecture for those desiring a different format: www.youtube.com/watch?v=8DeZ...

The capacity of vaccine induced immunological memory, a stellar open-access review by @profshanecrotty.bsky.social www.cell.com/immunity/ful...

My new comprehensive review of Immune Memory to Vaccines is out! It has an emphasis on human vaccines. It is also accompanied by a full video lecture. Enjoy! @lji.org @cp-immunity.bsky.social authors.elsevier.com/sd/article/S...

In our latest study in @cp-immunity.bsky.social, we followed dynamics of vaccine-specific Tfh cells for 60+ weeks after immunization. authors.elsevier.com/a/1m3mV3qNrU... We captured >500,000 CD4 T cells including >36,000 vaccine-specific Tfh by scRNAseq, giving an unprecedented longitudinal detail.

thanks!

In our latest vaccine immunology study we tested whether it is possible to simultaneously prime multiple classes of broadly neutralizing antibodies (bnAbs) against HIV using a combination of germline-targeting (GT) immunogens. www.science.org/doi/10.1126/... @scienceimmuno.bsky.social @lji.org

A good news article in Nature today following up on these papers www.nature.com/articles/d41...

mRNA vaccines for HIV trigger strong immune response in people

Results from early-stage trial show that 80% of participants who received one of two HIV vaccine candidates produced antibodies against viral proteins.

One of our obsessions in the Crotty lab is to better understand B-cell immunology in the context of vaccines. Rare B cells can have antibody specificities particularly important for protection against some diseases. In our most recent paper… @cp-immunity.bsky.social www.cell.com/immunity/ful...

Diverse priming outcomes under conditions of very rare precursor B cells

B cells that give rise to neutralizing antibody responses can be extremely rare in the naive B cell repertoire. Madden et al. show that delivery strategy and adjuvant selection affect the recruitment ...
