How the BrkB protein helps tuberculosis bacteria grow

Characterizing the requirement of the mycobacterial BrkB ortholog in TB pathogenesis

['FUNDING_OTHER'] · LAKE FOREST COLLEGE · NIH-11182684

What this research studies

Researchers will study a mycobacterial protein called BrkB that may be important for TB growth and transmission. In the lab they will purify the BrkB protein and test whether it acts as a channel and interacts with other proteins. They will use a related bacterium (Mycobacterium marinum) in a zebrafish model and cell-based tests to see how BrkB mutations change bacterial growth inside and outside host cells, including conditions that mimic late-stage infection. The findings are intended to reveal whether blocking BrkB could weaken TB bacteria and guide development of new drugs.

Who could benefit from this research

Good fit: Adults with active pulmonary tuberculosis, especially those with drug-resistant or late-stage disease, would be the most relevant eventual candidates for therapies developed from this research.

Not a fit: People without tuberculosis, those with non-mycobacterial infections, and most children (under 21) are unlikely to benefit directly from this laboratory-focused work.

Why it matters

Potential benefit: If successful, this work could identify a new bacterial target that leads to drugs shortening treatment and helping people with drug-resistant or late-stage TB.

How similar studies have performed: Scientists have successfully used zebrafish and Mycobacterium marinum to study TB-like infection, but directly targeting BrkB is a new and untested approach for therapy development.
