Allogeneic AdV/CMV/EBV-specific T-lymphocytes

**Semantic type:** Cell|Pharmacologic Substance

**Definition:** A preparation of human leukocyte antigen (HLA)-matched or HLA-mismatched, allogeneic CD4+ and CD8+ T-lymphocytes, ex vivo incubated with synthetic peptides of the viral antigens of the three human viruses adenovirus (AdV), cytomegalovirus (CMV) and Epstein-Barr virus (EBV), with potential antiviral activity. Upon administration of the allogeneic AdV/CMV/EBV-specific T-lymphocytes after allogeneic hematopoietic stem cell transplantation (HSCT), these T-lymphocytes may kill AdV, CMV, and/or EBV-infected cells, and may prevent or reduce the severity of viral infections by these pathogens.

**Synonyms:** - Allogeneic AdV/CMV/EBV Multi-virus-specific T Lymphocytes
