Deborah Persaud, of Johns Hopkins University Medical School, is the lead author of a report recounting the child's treatment. The identity of the little girl, who was born to an HIV-positive woman in rural Mississippi, has yet to be released. What we do know is that she is only the second person in the world — and the first child — to be cured of HIV in its devastating 32-year history. If the case is confirmed, it is truly unprecedented.

A new study, published in Nature Communications, highlights the role of a protein called PCAF, which seems to successfully trigger a series of chemical and genetic events that allow nerves to regenerate. When we injected PCAF into mice with damage to their central nervous system, this significantly increased the number of nerve fibres that grew back, indicating that it may be possible to chemically control the regeneration of nerves in the central nervous systems.

How the treatment worked:

1) One of the patient's two olfactory bulbs was removed and the olfactory ensheathing cells (OECs) were grown in culture

2) 100 micro injections of OECs were made above and below the damaged area of the spinal cord

3) Four strips of nerve tissue were placed across an 8mm gap in the spinal cord. The scientists believe the OECs acted as a pathway to stimulate the spinal cord cells to regenerate, using the nerve grafts as a bridge to cross the severed cord

Darek Fidyka, who was paralysed from the chest down in a knife attack in 2010, can now walk using a frame.

The treatment, a world first, was carried out by surgeons in Poland in collaboration with scientists in London.

Details of the research are published in the journal Cell Transplantation.

"The first bionic hand that allows an amputee to feel what they are touching will be transplanted later this year in a pioneering operation that could introduce a new generation of artificial limbs with sensory perception.
