AI-guided discovery of the IRF4-PAICS-LDHA axis as a multitarget hub linking tumor metabolism to CD8+ T cell exhaustion in DLBCL

A metabolic pathway controlling immune evasion in aggressive lymphoma responds to existing drugs, suggesting a new combination therapy approach.

An AI-guided integrative analysis of DLBCL single-cell transcriptomics identified the IRF4-PAICS-LDHA metabolic-immune axis as a multi-targetable hub linking glycolytic reprogramming to CD8+ T cell exhaustion and immune evasion. Functional validation showed that metabolic intervention (methotrexate or LDHA knockdown) reversed T cell exhaustion and suppressed tumor growth, suggesting a new combination immunotherapy strategy for DLBCL.
