Rapid release encapsulated bioactive agents for inducing or potentiating an immune response and methods of using thereof.

摘要

A composition for inducing or potentiating an immune response, preferably a CTL, T helper cell, or neutralizing antibody response in a subject, comprising an antigen and/or a non-antigen bioactive agent capable of inducing or potentiating such an immune response encapsulated in a polymeric composition, wherein the polymeric composition comprises a blend of (a) a polymer present in an amount sufficient to provide structural integrity to the polymeric composition, and (b) a rapidly biodegradable component, a rapidly dissolving component, a rapidly swelling component, or a component that causes osmotic rupture of the encapsulated polymeric composition is disclosed. Single polymer compositions for achieving such an immune response are also disclosed. Methods for inducing or potentiating a CTL, T helper cell or neutralizing antibody response using the above-identified compositions are disclosed.
