    Multiple myeloma is characterized by malignant plasma cell proliferation and a profoundly immunosuppressive tumor microenvironment.

  • 2

    CAR-T therapy targeting BCMA has shown deep responses in relapsed/refractory multiple myeloma but is limited by cytokine release syndrome (CRS).

  • 3

    Cytokine release syndrome is a hyperinflammatory process driven by CAR-T-derived cytokines and monocyte/macrophage activation.

  • 4

    IL-37 and IL-38 are emerging as anti-inflammatory regulators that may modulate CAR-T-associated hyperinflammation.

    Leveraging IL-37 and IL-38 could improve the safety and efficacy of CAR-T therapies in multiple myeloma.
