NewLimit finds 19 payloads that restore regulatory activity in old T cells

NewLimit/T cell rejuvenation

NewLimit's January-February 2026 update reported 19 payloads that rescue regulatory activity in old T cells, alongside 50 that make old hepatocytes look young and progress in clinical-grade chemistry for lead compounds.

• 19 transcription factor sets restore regulatory T cell activity; 50 payloads restore youthful function in hepatocytes.
• AI system Ambrosia achieved >2X faster payload discovery through multi-task modeling across programs.
• Lead liver medicine moved to clinical-grade lipid chemistry; preclinical kidney disease model shows age-related vulnerability.
