Cord Blood-derived CMV/AdV/EBV/BKV-specific Cytotoxic T-lymphocytes

**Semantic type:** Cell|Pharmacologic Substance

**Definition:** A population of allogeneic expanded cord blood (CB)-derived cytotoxic T-lymphocytes (CTLs) that are specifically reactive to cytomegalovirus (CMV), Epstein-Barr virus (EBV), adenovirus (AdV), and human polyomavirus type I (BKV), with potential antiviral activity. Infusion of the CB-derived CMV/AdV /EBV/BKV-specific CTLs into CB hematopoietic stem cell transplant (HSCT) recipients may provide virus-specific cellular immunity, thereby preventing the infection or reactivation of certain viral-associated diseases.

**Synonyms:** - Allogeneic Cord Blood-derived CMV/AdV/EBV/BKV-specific CTLs - Cord Blood-derived CMV/AdV/EBV/BKV-specific T-cells - UCB-derived CMV/AdV/EBV/BKV-specific T-cells
