Dendritic cells infected with a vaccinia virus interleukin-2 vector secrete high levels of IL-2 and can become efficient antigen presenting cells that secrete high levels of the immunostimulatory cytokine IL-12
Dendritic cell (DC) therapies using DC presenting tumor antigen/s can induce CD8+ CTL that mediate tumor eradication, nonetheless many patients remain unresponsive. Thus, cytokine gene vectors applied to DC may amplify these responses. Herein, we examined the responses that monocyte-derived DC (at different maturational stages) make when infected with a vaccinia virus-interleukin-2 (VV-IL-2) vector in vitro. VV-IL-2-infected DC secreted significant levels of bioactive IL-2 and maintained their...[Show more]
