Q

CAR T-Cell Therapy mechanism

A

customized to each patient
collect T-cells from patient → re-engineer to produce chimeric antigen receptors (CARs) → CARs recognize/bind specific Ags on cancer cells → revamped T-cells are infused back into patient → CAR T-cells continue to multiply and recognize/kill cancer cells that have target on cell surface

137
Q

CAR T-Cell adverse effects

A

tumor lysis syndrome
cytokine release syndrome (managed with steroids, tocilizumab blocks IL-6 activity also helps)
neurologic effects: severe confusion, seizure-like activity, impaired speech (responds to steroids but not tocilizumab)
