Trojan Horse Strategy: How A Prodrug For Moxifloxacin Kills TB Persisters

When the TB drug moxifloxacin was masked as a prodrug form, the prodrug’s permeability into the bacteria improved significantly. Once inside the bacteria, the prodrug is activated by an enzyme leading to the generation of the active drug moxifloxacin within the bacteria. This strategy significantly enhanced the lethality against TB persisters, thus effectively reducing the population of persisters

The Lancet ERCP Data Controversy Highlights The Limitations of India’s AMR Surveillance

India’s AMR surveillance network is primarily built on a few dozen tertiary-care hospitals. The problem is not the quality of data from these tertiary centres; it is the narrowness of the sample. A surveillance system built only on a few dozen largest hospitals cannot speak for the entire country

Reprogramming Macrophages: A New Hope for Tuberculosis Therapy

Why does TB therapy take six-nine months, and why do some Mycobacterium tuberculosis inside macrophages survive antibiotics better than others? Rigorous experiments have now revealed that macrophage’s own metabolism and the host cell where the bacteria live play a key role in shaping drug tolerance

The Silent Pandemic: How Antibiotic Resistance Threatens Us All

Genomic surveillance reveals resistance among key pathogens like Escherichia coli, Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Vibrio cholerae is rising rapidly, with susceptibility to commonly used antibiotics often falling below 20%

Disarming a Tough Brain Cancer: How to Tackle Drug Resistance in Glioblastoma

Rather than trying to develop even stronger chemotherapy drugs, our approach aims to make cancer cells more sensitive to existing treatments by blocking their defence mechanisms. In this case, blocking TLK1 protein’s activity weakens the ability of cancer cells to survive, making it easier to kill them
