CD40 ligand enhances immunogenicity of vector-based vaccines in immunocompetent and CD4+ T cell deficient individuals

Highlights ► Vector-expressed CD40L functions as a vaccine adjuvant for circulating and lung mucosal T cell responses. ► CD40L adjuvant activity in booster immunizations is route-dependent. ► CD40L adjuvant activity enhances the magnitude of vaccine-induced polyfunctional T cell responses. ► CD40L c...
