Fibroblasts are key structural cells & some types are associated with cancer progression. In @Nature, @akshayk25, @SorenMuller1, @TurleyLabGNE & team found that depleting a subset of these cells in tumors can improve responsiveness to cancer immunotherapy: go.nature.com/3RmlnJm

Using novel genetic tools, we show TGFβR2 signaling in healthy Dermatopontin (DPT)+ universal fibroblasts is essential for LRRC15+ CAF formation in mouse models of pancreatic cancer. These data validate prior in silico predictions that TGFβ is the key driver of these CAFs. 3/

Previous scRNAseq studies in cancer identified a predominant population of activated LRRC15+ myofibroblasts, that express high levels of immunosuppressive genes and associate with immunotherapy resistance. How LRRC15+ CAFs develop and function has remained unanswered 🤔2/

Once LRRC15+ CAFs form, how do they impact tumor immunity? We made an LRRC15-DTR mouse to selectively ablate LRRC15+ CAFs from the TME🎯. Upon depletion, total tumor fibroblasts are diminished and tumor growth is significantly impaired. 4/

Kinetic scRNAseq of LRRC15+ CAF depleted tumors showed a recalibration of the tumor fibroblast compartment back towards a universal fibroblast-like state, highlighting the push and pull between universal fibs and LRRC15+ myofibroblasts in dictating tumor progression. 5/

Immunologically, depletion of CD8+ T cells in LRRC15+ CAF depleted tumors reversed the improved tumor control. Additional analysis of tumor CD8+ T cells, in the absence LRRC15+ CAFs, displayed enhanced effector function, indicating LRRC15+ CAF suppression of T cell activity. 6/

Ultimately, this enabled us to ask if LRRC15+ CAFs limit response to immunotherapy. Here we find depletion of LRRC15+ CAFs markedly improved response to aPDL1 treatment, validating prior clinical associations between LRRC15+ CAFs and resistance to immune checkpoint blockade. 8/

Imaging of tumors showing CD8s in close proximity to LRRC15+ CAFs further suggested cross-talk between these cells. And when co-cultured directly with LRRC15+ CAFs, CD8+ T cell functionality was suppressed, indicating LRRC15+ CAFs can directly limit their effector potential. 7/

Most importantly, these exciting findings (and many more in the paper) were only possible b/c of the contributions of our incredible team of scientists. A big thank you 🙏🏾 to our co-authors and incredibly supportive community @genentech! There is still so much more to learn! /end

Together, our findings tie together computational inferences, clinical associations, and now, in vivo validation, to support targeting of LRRC15+ CAFs to improve cancer immunotherapy💊. Such strategies may also be relevant in other diseases where similar myofibroblasts exist 9/

the first paper of the lab has been published. I feel the luckiest in the universe🤩 we found a sub-population of tumor cells that survive T cell attack and did scRNA-seq specifically in their niche. authors.elsevier.com/a/1exmgL7PXio3…
