I wonder how it works for <pathogen name> <vaccine type> in general.. actually could be checked with reasonable effort

Nature - mRNA vaccines targeting SARS-CoV-2 also sensitize tumours to immune checkpoint inhibitors.

The majority of exploratory T-cell receptor (TCR) repertoire studies search for TCRs enriched in samples and donors under a certain condition/pathology. But what if we swap the background (control) and test samples? Turns out, this trick can help us to identify and characterize

The final version of our "Thrifty" paper is up now: https://t.co/pgoV81pKjp . We were motivated to fit wide-context mutation models based on previous analyses showing "mesoscale" effects and a position-specific effect. But, how to avoid exploding the number of parameters? 🧵

Convolutional embedding models efficiently capture wide sequence context in antibody somatic hypermutation, avoiding exponential k-mer parameter scaling and eliminating the need for per-site modeling.

1/ My first time tweeting preprint since March 2020... Analysis of >600 CAR-T recipients from two 🇺🇸 time zones. Earlier infusions (before 3pm) seem to be better! 😳 ⚠️ Still needs peer review. I don't see breakdown of specific CAR products by ≤2:59p vs ≥3:00p, for instance.

Perhaps we can finally evaluate stability of receptor-antigen complexes without spending days of MD simulations?
Researchers have developed a #DeepLearning system called BioEmu that rapidly generates diverse protein conformations, enabling fast, accurate insights into protein flexibility and function. Learn more this week in Science: https://t.co/Pe15hm9F52

🚀 What do Bayesian inference and skydiving have in common? Both demand trust under uncertainty. Our CTO @bvdmitri used RxInfer to clean up noisy pose estimates from his 500th skydive — showing how probabilistic inference fills the gaps where standard ML fails #Bayes #Skydiving
