Cell-autonomous control of CAR signaling and receptor shedding via ADAM17-mediated proteolysis
AIR, a minimal 15-amino acid motif, enables rapid, activation-dependent shedding of surface receptors through ADAM17, allowing T cells to autonomously tune receptor expression. AIR reduces tonic CAR s...

Environmental exposure trains the immune system to dampen allergic responses
Clean living conditions that lessen exposure to microorganisms are linked to an increase in allergies. Mouse data reveal how the environment affects allergic immune responses.

IL-9 as a naturally orthogonal cytokine with optimal JAK/STAT signaling for engineered T cell therapy
Cytokines optimize and fine-tune effector T cell responses. Here, Jiang et al. utilize IL-9, with scarce receptor expression in normal tissues, to boost IL-9R engineered T cells for cancer therapy. IL...

Glad to see our work on an advanced CAR-T cell therapy for prostate cancer out now @natbiomedeng.nature.com (www.nature.com/articles/s41...). We will continue to work on developing safer and more efficacious immunotherapies!
