Indiana CTSI ACCELERATING CLINICAL AND TRANSLATIONAL RESEARCH Indiana C linical and T ranslational S ciences I nstitute Mycobacterium tuberculosis One third of the world population is currently infected. Over 8 million new cases of TB in % of those infected become sick or infectious at some time in their lives. An estimated 1.6 million TB deaths occurred in Drug-resistance is on the rise No effective vaccine against pulmonary TB

Indiana CTSI ACCELERATING CLINICAL AND TRANSLATIONAL RESEARCH Indiana C linical and T ranslational S ciences I nstitute Lines of Investigation– Schorey laboratory Molecular and cellular basis of TB pathogenesis. Exosomes as TB vaccine candidates Diagnostic tools for TB. Supported by: National Institutes of Health - R01 AI R01 AI Gates Exploration Grant

Indiana CTSI ACCELERATING CLINICAL AND TRANSLATIONAL RESEARCH Indiana C linical and T ranslational S ciences I nstitute What is available: Acid-fast smear test using sputum Culturing approaches using sputum as the source of bacilli Detection from patient blood antibodies or T cells specific for mycobacterial components Detection of M.tb DNA or RNA in patient bodily fluids or sputum Detection of other mycobacterial components in patient bodily fluids Diagnostic needs: High specificity and sensitivity as well as a test which is rapid, requires minimum manipulation, easy to use and is of minimal cost.

Indiana CTSI ACCELERATING CLINICAL AND TRANSLATIONAL RESEARCH Indiana C linical and T ranslational S ciences I nstitute Isolation of M. tuberculosis Lipoarabinomannan (LAM) from urine of TB patients using an antibody-based microfluidic detection platform TB Detection Project Couple LAM antibodies to chip/sensor substrate using micro-stamping techniques. Converting current glass microfluidic platform to hard plastic, including synthesis of on-chip membranes Develop and assemble hand-held chip reader and design large-scale hard polymer chip production methods. Test chip prototypes first using urine “spiked” with LAM, then urine samples from TB patients (Kenya) and control samples.
