New Vulnerabilities Uncovered in Tuberculosis Germs by Indian Scientists

UPDATE - follow-up to CSIR-CCMB team identifies potential new targets to fight Tuberculosis: Researchers in Hyderabad have pinpointed new vulnerabilities in the germ responsible for Tuberculosis. India bears a heavy burden for this illness, holding nearly twenty-five percent of worldwide cases and roughly thirty-three percent of drug-resistant infections based on figures from the World Health Organisation's Global TB Report 2025.

Research Details

Heading the study was Vinay Kumar Nandicoori, who directs the CSIR-Centre for Cellular and Molecular Biology. The work was executed by Priyadarshini Sanyal and Jagadeeshwari Uppada alongside partner teams from the Institute of Mathematical Sciences in Chennai, headed by Areejit Samal, and the Translational Health Science and Technology Institute in Faridabad. By merging computer models with lab tests, the group mapped out ninety-two core parts and nearly two hundred molecular reactions powering the germ's protein delivery system.

Methodology and Impact

The investigators targeted the SecA1 and Tat pathways using CRISPR-based gene-silencing tools to lower their function. Slowed pathogen growth showed up both in lab dishes and inside immune cells. Dr Uppada noted that this delivery network is crucial for the germ to stay alive. Further study led by Dr Sanyal showed that breaking these systems stopped the transport of over one hundred proteins for SecA1 and about one hundred forty for Tat, causing visible damage and leaks in the cell wall.

Context

Tuberculosis remains a major global public health concern requiring months of antibiotic treatment, and new drug-resistant strains make healing increasingly difficult. While these findings in Molecular & Cellular Proteomics point toward prospective paths for future treatments, turning this discovery into ready medicines will demand several more years of scientific work.
