Dai Y., Aizenbud L., Qin K. et al. Nature. 644: 527–536 . (2025).
doi: 10.1038/s41586-025-09188-4.

Summary of the findings

This study systematically mapped autoantibody (AAb) responses against 6,172 extracellular and secreted proteins in a large cohort of checkpoint immunotherapy (CPI)-treated patients. The authors found that cancer patients harbor remarkably diverse AAb repertoires that distinguish them from healthy individuals. While AAbs showed limited association with immune-related adverse events, many AAbs were strongly linked to treatment response, either favorably or unfavorably. Key targets included cytokines such as type I interferons, IL-6, and OSM, as well as the TNF superfamily member TL1A and BMP receptor components. Functional experiments confirmed that several of these AAbs neutralize their targets, and preclinical mouse models validated that antibodies neutralizing IFN-I or TL1A improved CPI efficacy. These results establish AAbs as an underappreciated source of inter-patient variability in immunotherapy outcomes.

Future impact

These findings open several promising directions. Because AAbs effectively act as naturally occurring biologic drugs, the targets they highlight can serve as a shortlist for therapeutic development or drug repurposing. For instance, existing agents like anifrolumab (an IFNAR-blocking antibody approved for lupus) could be explored in combination with CPIs. Conversely, AAbs that impair treatment point to pathways that should be preserved or enhanced, such as BMP receptor signaling. More broadly, the “autoantibody-wide association study” framework introduced here could be applied across diseases to uncover functional roles of humoral autoreactivity, much as genome-wide association studies have done for genetic variation. Larger cohorts and prospective clinical trials will be needed to confirm causal relationships and translate these findings into improved patient stratification and combination treatment strategies.
