Expanding T cells in the presence of mannose can generate T cells with progenitor like properties www.cell.com/cancer-cell/...
cell.com
Mannose metabolism reshapes T cell differentiation to enhance anti-tumor immunity
Qiu et al. identify that reduced mannose metabolism is a key characteristic of T cell dysfunction. Enhancing mannose metabolism in T cells through D-mannose supplementation boosts anti-tumor activity, limits exhaustion differentiation, and maintains T cell stemness. Mechanistically, D-mannose promotes the OGT-mediated O-GlcNAcylation and stabilization of β-catenin, enhancing T cell stemness.
