Nanotechnology combats fatal brain infections
Minute Antibacterial Particles Destroy Drug-Resistant Germs
Doctors may get a new arsenal for meningitis treatment and the war on drug-resistant bacteria and fungal infections with novel peptide nanoparticles developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN) of Singapore and reported in Nature Nanotechnology.
Study suggests antibiotic may prevent dreaded brain fever

Two researchers from National Brain Research Center (NBRC) suggest that a common antibiotic called minocycline may prevent children from death due to Japanese encephalitis (JE), or commonly known as brain fever. Japanese Encephalitis virus is the causative agent for JE. Although there is no consolidated official figure for JE cases in India, a rough estimate would indicate a few thousands fatalities every year. The team found that minocycline, an USFDA approved drug, often used to treat acne, limits the death by reducing the microglial activation, neuronal death as well as viral replication. Microglia are cells that act as the “cleanup crew” for the Central Nervous System (CNS). They destroy damaged cells by releasing toxins and engulfing them. Should they become activated and release their toxins in the CNS, the toxins will kill the healthy neurons critical for normal function of brain.
