How tuberculosis bacteria make and send key sugar-fat molecules

Assembly and export of mycobacterial lipoglycans

NIH-funded research Colorado State University · NIH-10862546

Researchers are working to understand how TB bacteria build and move certain surface sugar-fat molecules that help them infect people so future treatments can target them.

What this research studies

This project focuses on PIM, LM and LAM, special sugar-fat molecules on the surface of tuberculosis and leprosy bacteria that affect how they interact with human cells. Scientists will determine the detailed structures of these molecules, identify the bacterial genes and enzymes that make them, and study how the molecules are transported to the cell surface using genetic and biochemical methods. They will generate and examine bacterial mutants missing specific biosynthesis or export steps to see how those changes affect bacterial survival and immune interactions. The goal is to reveal bacterial weak points that could guide new drugs or vaccines.

Who could benefit from this research

Good fit: People with active tuberculosis or leprosy, or individuals willing to provide clinical samples or bacterial isolates, would be most relevant to this work.

Not a fit: People without mycobacterial infections or those with unrelated conditions are unlikely to see direct benefit from this laboratory-focused research.

Why it matters

Potential benefit: Understanding these surface molecules could point to new drug or vaccine targets to help people with tuberculosis or leprosy.

How similar studies have performed: Researchers have clarified parts of PIM/LM/LAM structure and biosynthesis over the past 25 years, but key steps in their complete biogenesis and export are still unresolved.
