How Bacteria Invade the Brain

By March 6, 2023No Comments

A new study led by researchers at Harvard Medical School details the step-by-step cascade that allows bacteria to break through the brain’s protective layers — the meninges — and cause brain infection, or meningitis, a highly fatal disease.

The research, conducted in mice and published March 1 in Nature, shows that bacteria exploit nerve cells in the meninges to suppress the immune response and allow the infection to spread into the brain.
