Preclinical studies have shown that photodynamic therapy (PDT) of tumors augments the host antitumor immune response. However, the role of the PDT effect on tumor cells as opposed to the host tissues has not been determined. To test the contribution of the direct effects of PDT on tumor cells to the enhanced antitumor response by the host, we examined the immunogenicity of PDT-generated murine ...
Current acellular pertussis vaccines have various shortcomings, which may contribute to their suboptimal efficacy and waning immunity in vaccinated populations. This calls for the development of new pertussis vaccines capable of inducing long-lived protective immunity. Immunization with whole cell pertussis vaccines and natural infection with Bordetella pertussis induce distinct and more protec...
In this article we discuss the following: (1) acellular vaccines are immunogenic, but responses vary by vaccine; (2) pertussis antibody levels rapidly wane but promptly increase after vaccination; (3) whole-cell vaccines vary in immunogenicity and efficacy; (4) whole-cell vaccines and naturally occurring pertussis generate predominantly T-helper 1 (Th1) responses, whereas acellular vaccines gen...
