Allogeneic Cytomegalovirus-Specific Cytotoxic T lymphocytes

**Semantic type:** Cell|Pharmacologic Substance

**Definition:** A population of allogeneic cytotoxic T lymphocytes (CTLs) specifically reactive to the herpes virus cytomegalovirus (CMV) with potential immunomodulating and antiviral activities. Upon immunoprophylactic adoptive cell therapy infusion with allogeneic cytomegalovirus-specific cytotoxic T lymphocytes, these CTLs may help reconstitute CMV-specific CTL responses in CMV-infected immunocompromised hosts after allogeneic hematopoietic stem cell transplant, thereby potentially preventing the occurrence of CMV viral disease or reducing the amount of antiviral drug therapy.
