Effects of Surfactants on the Innate Immune System

Completed · Not applicable

Conditions studied: Healthy

In brief

In this study we will test the ability of different commercially available hand soaps to effect the amount of anti-microbial peptides present on the surface of the human skin after washing with these soaps. Based on our experiments on pig skin, we expect the amount of antimicrobial peptide expression to decrease after using these different soaps.
