Promising but preliminary

ARID1B mutations promote immune evasion in acute myeloid leukemia through upregulating VISTA expression.

Blocking a specific immune checkpoint in AML cells with ARID1B mutations restores the immune system's tumor-fighting ability.

ARID1B loss-of-function mutations in AML cells upregulate the immune checkpoint VISTA, enabling immune evasion; pharmacological VISTA blockade restores T-cell-mediated antitumor immunity in ARID1B-mutant AML models. This record was retained from the prior triage attempt for PubMed pipeline handoff.

Why it surfaced

Novel chromatin-to-immunocheckpoint mechanism in AML with therapeutic implications; VISTA is increasingly targeted in clinical trials; ARID1B mutation frequency in AML makes this actionable for patient stratification.
