The importance of IgA in the protection and control of infectious diseases

Project Details

The human body produces more IgA than any other immunoglobulin, especially in mucosal secretions. However, the importance of IgA in both protection from HIV-1 and control of HIV-1 disease progression is highly controversial. Results from the only protective human HIV vaccine trial associated plasma IgA with reduced vaccine efficacy. In contrast, recent studies suggest that mucosal HIV-specific IgA may be protective. This project aims to further explore the mechanisms behind both the protective and immunomodulatory role of IgA in the control of HIV-1 and other infectious diseases.
