Increasing Cellular Immune Response in Liposomal Formulations of DOTAP Encapsulated by Fusion Protein Hspx, PPE44, And Esxv, as a Potential Tuberculosis Vaccine Candidate

Background: Due to the ineffectiveness of the BCG vaccine, especially in adult pulmonary tuberculosis (TB), and variable efficacies against childhood forms of TB, developing an effective TB vaccine is a major priority in controlling this disease. The aim of this study was to evaluate the immunogenicity of a DOTAP liposome formulation containing a fusion protein (FP) containing Mycobacterium tuberculosis HspX, PPE44, and EsxV.
