Corticosteroids ameliorate CAR T-cell-induced cytokine-release syndrome without inhibiting multiple myeloma treatment

Background <p>Cytokine-release syndrome (CRS) is a common toxicity of chimeric antigen receptor (CAR) T cells. CRS is often treated with corticosteroids such as dexamethasone. Dexamethasone is also used to treat multiple myeloma. To model CRS after CAR T-cell treatment of multiple myeloma (MM), three cell types are required: monocyte-lineage cells, CAR T cells, and MM cells. Some cytokines important in…
