Mycobacterial DNA-binding protein 1 is critical for BCG survival in stressful environments and simultaneously regulates gene expression.

Survival of the live attenuated Bacillus Calmette-Guérin (BCG) vaccine amidst harsh host environments is key for BCG effectiveness as it allows continuous immune response induction and protection against tuberculosis. Mycobacterial DNA binding protein 1 (MDP1), a nucleoid associated protein, is essential in BCG. However, there is limited knowledge on the extent of MDP1 gene regulation and how this influences BCG survival.

Antibodies against native proteins of Mycobacterium tuberculosis can detect pulmonary tuberculosis patients.

Accurate point-of-care testing (POCT) is critical for managing tuberculosis (TB). However, current antibody-based diagnosis shows low specificity and sensitivity. To find proper antigen candidates for TB diagnosis by antibodies, we assessed IgGs responsiveness to Mycobacterium tuberculosis proteins in pulmonary TB (PTB) patients.

Monitoring IgG against Mycobacterium tuberculosis proteins in an Asian elephant cured of tuberculosis that developed from long-term latency.

Tuberculosis (TB) is fatal in elephants, hence protecting elephants from TB is key not only in the conservation of this endangered animal, but also to prevent TB transmission from elephants to humans. Most human TB cases arise from long-term asymptomatic infections. Significant diagnostic challenges remain in the detection of both infection and disease development from latency in elephants due to their huge bodies.

Demonstration of Mitochondrial Damage and Mitophagy in Cisplatin-Mediated Nephrotoxicity.

Cisplatin is a chemotherapeutic widely used in the treatment of various types of solid tumors. Acute kidney injury is the most critical dose-limiting factor in cancer patients treated with cisplatin; mitochondrial dysfunction and resultant cell damage by reactive oxygen species released from damaged mitochondria are suspected to be involved in the kidney injury. Pathological features of mitochondrial damage in relation to cisplatin-mediated nephrotoxicity, however, is not fully described.
