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...

New in Nature Immunology: @rohamparsa.bsky.social & @danmucida.bsky.social / @rockefeller.edu reveal that where a T cell gets activated shapes what it becomes, foundational to our mission of programming immunity for early disease detection. Read more ▶️ biohub.org/blog/track-t...
Illustration showing how T cells, when activated, turn on a red fluorescent protein and migrate through the bloodstream to three organs - lungs, lymph node, spleen – taking on different roles in different tissues.

A new tool from Rockefeller's @danmucida.bsky.social and @czbiohub.bsky.social allows scientists to closely follow newly activated T cells as they travel and change during an infection—it may inform future therapies for infection, cancer, and autoimmunity. 🔗: bit.ly/3NjZEWD

Excited to share our new preprint! We studied how T cells are functionally & clonally shaped across organs over time. With the new TRACK mice, we genetically label recently activated T cells with tdTomato and track their migration across tissues. #immunology #science www.biorxiv.org/content/10.1...

I’m looking for a postdoc to join my group here at Chan Zuckerberg Biohub NY! This position offers the chance to delve deeply into the dynamic and functional behavior of T cells, exploring how their fate decisions shape immune responses in health and disease. More information at parsalab.science
parsalab.science
The Parsa Laboratory at CZ Biohub New York
The Parsa laboratory investigates the functional and clonal dynamics of T cells during various immune responses. Using innovative genetic approaches, we will precisely track and analyze the behavior of polyclonal perturbation-specific T cells over time and space. We seek to uncover the rules governing the development of effector and memory T cells, ultimately enhancing our understanding of adaptive immunity and advancing therapies for various diseases, including cancer and autoimmunity.

I’m very fascinated about this study showing stem cell-like effector CD4 T cells that can become the classic T helper subsets. In tumors, Tregs suppress these cells, blocking Th1 seeding and anti-tumor effects! Jenkins lab also recently described a similar CD4 phenotype with different implications.

Differentiation fate of a stem-like CD4 T cell controls immunity to cancer - Nature
A population of tumour-specific PD1+TCF1+ CD4 T cells in tumour-draining lymph nodes is capable of self-renewal and differentiation into CD4 effector cells, thereby controlling CD8 T cell activity.
