Glycan shielding enables TCR-sufficient allogeneic CAR-T therapy
SPPL3 deletion modifies glycosylation on primary T cells, reducing allogeneic immune
responses without impairing tumor control by anti-CD19 allogeneic CAR-T cells. SPPL3-null,

Bad news — the effective freeze at the NIH’s Center for Scientific Review hits a major chemical biology study section. Not good. @jeremymberg.bsky.social
🚨 Chemical Biology & Probes study section (formerly SBCB, one of two NIH panels that reviews chemistry #chemsky 🧪) was abruptly POSTPONED w/no specific plans for rescheduling, less than 24h before start.
If this affects you call your reps & senators, talk to local news, make your voice heard 📢 👩🔬
