Bacterial Nanosyringes Deliver Drugs and Gene Therapy to Human Cells.

Researchers have repurposed tiny syringe-like structures produced by some bacteria to deliver molecules directly into human cells, potentially overcoming a challenge in modern medicine of ensuring therapeutics are delivered into the precise cells that need to be treated. Meanwhile, chronic pain affects millions of people worldwide, but despite advances in research, this knowledge hasn't necessarily resulted in better outcomes for those with chronic pain.
