Induction of HIV-1-specific cellular and humoral immune responses following immunization with HIV-DNA adjuvanted with activated apoptotic lymphocytes

Abstract Delivery of DNA encoding foreign antigens into mammalian cells can induce adaptive immune responses. There are currently many DNA-based vaccines in clinical trials against infectious diseases and cancer but there is a lack of adjuvants for improvement of responses to DNA-based vaccines. Her...

Description
Summary:Abstract Delivery of DNA encoding foreign antigens into mammalian cells can induce adaptive immune responses. There are currently many DNA-based vaccines in clinical trials against infectious diseases and cancer but there is a lack of adjuvants for improvement of responses to DNA-based vaccines. Here, we show augmented systemic and mucosa-associated B cell responses after immunization with a cocktail of seven different plasmids (3 env , 2 gag , 1 rev , 1 RT ) combined with mitogen activated apoptotic syngeneic lymphocytes in mice. In addition we show that apoptotic cells can function as adjuvant for induction of cellular immune responses in a magnitude comparable to the cytokine adjuvant GM-CSF in mice. These data suggest that activated apoptotic lymphocytes can act independent as adjuvants to improve antigen-specific DNA vaccines.
