Abstract [en]

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.
