Thanks for a lovely time in Cambridge - great to see you all again. Already looking forward to next time.
Great to welcome former PhD student, now Assistant Professor @krishaurum.bsky.social of the DTU back to the Department of Pathology. Excellent presentation on TIL TCRs, peptide-MHC complexes and his recent paper on AI-designed pMHC binders (artificial TCRs).

Our paper is now out with peer review!

This was such a fast paced and fun project to be involved in and thanks to all the co-authors involved.

Read about it below in Tims breakdown!
Thrilled to announce our paper, "De novo-designed pMHC binders facilitate T cell-mediated cytotoxicity toward cancer cells," is officially out in @science.org!

We used generative AI to build a 'GPS' for immune cells to hunt cancer.

It's not the models, it's the data!

We show that a substantial proportion of a widely used TCR-pMHC database does not functionally validate, causing underestimation of performance of TCR-pMHC prediction models.

A functionally validated TCR-pMHC database for TCR specificity model development
Accurate prediction of TCR specificity forms a holy grail in immunology and large language models and computational structure predictions provide a path to achieve this. Importantly, current TCR-pMHC ...
