Autologous Dendritic Cells Transduced with Wild-type p53 Adenovirus Vaccine

**Semantic type:** Cell|Immunologic Factor|Pharmacologic Substance

**Definition:** A cancer vaccine consisting of autologous dendritic cells (DCs) transduced with a recombinant replication-defective adenoviral (Ad) vector encoding the full-length wild-type (wt) cancer tumor antigen p53 protein (TP53; p53), with potential immunomodulating activity. Intradermal vaccination with the autologous DCs transduced with wt p53 Ad vaccine may stimulate the host immune system to mount a cytotoxic T-lymphocyte (CTL) response against tumor cells overexpressing wt and mutant forms of p53, resulting in tumor cell lysis. p53, a tumor suppressor gene, is overexpressed and/or mutated in many tumor cells, resulting in the loss of apoptosis regulation and abnormal cell proliferation.

**Synonyms:** - Ad.p53-DC - Autologous DCs Transduced with Ad.p53 Vaccine - Autologous DCs Transduced with wt p53 Ad Vaccine - Dendritic Cell Based p53 Vaccine - Dendritic Cell-based p53 Vaccine
