Abstract

Compositions and methods for treating immune cells and activating immune responses are disclosed. The compositions comprise one or more optically active chiral cationic lipids.

Claims (4)

1. A method of enhancing a DOTAP induced immunostimulatory effect in an immune system of a mammal, said method consisting of the step of administering a chiral cationic lipid consisting of R-DOTAP to the mammal.

2. The method of claim 1 , wherein the immunostimulatory effect includes production of immune system regulatory molecules.

3. The method of claim 2 , wherein the immune system regulatory molecules include at least one cytokine or chemokine.

4. The method of claim 3 , wherein the at least one cytokine or chemokine is selected from CCL-3, CCL-4, CCL-5, CCL-19, IL-2, IL-8, IL-12, or combinations thereof.
