Who could benefit from this research

Could help

Patients at risk for or affected by Mycobacterium tuberculosis or Francisella tularensis infections could benefit from advances deriving from this research.

Less likely to help

Individuals not at risk for these infections may not directly benefit from this study.

What this research studies

MAIT cells are a first line of defense against certain bacterial infections and are activated by unique metabolite antigens presented by MR1. This research will identify specific antigens and the presentation pathways that best stimulate MAIT cells to protect against Mycobacterium tuberculosis and Francisella tularensis. The team will explore how different infections load these metabolites onto MR1 and how to optimally deliver the right antigen through the correct pathway. The project is conducted at Texas Biomedical Research Institute in San Antonio, led by Shouxiong Huang, and includes studies in relevant models to understand protective MAIT cell responses.

Why it matters

Potential benefit: If successful, the work could guide new approaches to prevent or mitigate serious bacterial infections by promoting MAIT cell–mediated immunity.

How similar studies have gone: Previous work shows MAIT cells respond to certain bacterial antigens, with ongoing efforts to identify protective antigen pathways.
