The participants will be divided in two cohorts: 81 participants in Cohort 1: Large B-Cell Lymphoma (LBCL) 24 participants in Cohort 2: Follicular Lymphoma (FC) and Marginal Zone Lymphoma (MZL) The main questions it aims to answer are: 1. Can UF-KURE19 achieve a clinically meaningful complete response rate (CRR) of ≥ 45% in patients with relapsed/refractory LBCL at Day 90 post-infusion, per Lugano Revised Response Criteria? 2. Can UF-KURE19 achieve a CRR of ≥ 60% in patients with relapsed/refractory Follicular or Marginal Zone Lymphoma at Day 90 post-infusion? There is no comparison group. This is a single-arm study, (all participants receive UF-KURE19) with 2 cohorts as outlined above. Participants will: 1. Undergo leukapheresis for collection of their own T cells, which will be used to manufacture UF-KURE19. 2. Subsequently they will receive a single intravenous infusion of UF-KURE19 (10×10⁶ cells for patients ≥50kg; 7×10⁶ cells for patients \<50kg) Complete disease response assessments at Day 90 post-infusion per Lugano criteria 3. Undergo safety monitoring including adverse event collection, laboratory tests, neurological exams, CAR-T persistence assays, and replication-competent lentivirus (RCL) testing throughout the study 4. Be followed long-term for up to 15 years post-infusion for gene therapy safety surveillance per FDA requirements
