AI could speed up discovery of new medicines sheffielduni NatMachIntell
Predicting drug–target interaction is key for drug discovery. Recent deep learning-based methods show promising performance, but two challenges remain: how to explicitly model and learn local interactions between drugs and targets for better prediction and interpretation and how to optimize generalization performance of predictions on novel drug–target pairs.
Here, we present DrugBAN, a deep bilinear attention network framework with domain adaptation to explicitly learn pairwise local interactions between drugs and targets, and adapt in response to out-of-distribution data. DrugBAN works on drug molecular graphs and target protein sequences to perform prediction, with conditional domain adversarial learning to align learned interaction representations across different distributions for better generalization on novel drug–target pairs.

Deletion of SNX9 alleviates CD8 T cell exhaustion for effective cellular cancer immunotherapy - Nature CommunicationsThe efficacy of T-cell-based cancer immunotherapies can be compromised by T cell exhaustion. Here the authors develop a human ex vivo exhaustion model and, based on a CRISPR-Cas9 screen, identify SNX9 as a regulator of T cell exhaustion, showing that SNX9 knockout is associated with improved T cell function and anti-tumor activity in preclinical cancer models.
