Abstrakt: •Despite an unprecedented response with anti-BCMA CAR-T therapy, the majority of patients will ultimately relapse.•The T cell compartments of patients with relapsed/refractory multiple myeloma (RRMM) differ from those of patients with normal bone marrow and patients with newly diagnosed multiple myeloma.•Novel double-negative CD3+T cells were found in RRMM and CAR-T relapsed cases.•Most T cells in RRMM, and significant subsets of T cells in post-CAR-T relapsed cases, expressed multiple coinhibitory markers, including PD1, TIGIT, 2B4, and KLRG1.
