Zebrafish study reveals insights into spinal cord injuries
The immune system plays a key role in helping zebrafish nerve cells to regenerate after injury.
Macrophages are vital for fish to repair damaged connections 

New research into how zebrafish repair their damaged nerve connections could help in the creation of treatments for people with spinal cord injuries.

Scientists at the University of Edinburgh found that the immune system plays a key role in helping zebrafish nerve cells to regenerate after injury. It is hoped the discovery could eventually help people with spinal cord injuries regain control over their movement.

In the study, researchers found that large immune cells, known as macrophages, are vital for fish to repair damaged connections. Whilst these cells normally help the body with of infections, they also have a vital role to play in wound healing.

The team found that macrophages produce key molecules that deepen inflammation at the site of the spinal cord injury, enabling nerve cells to bridge the gap and repair lost connections. Researchers say the next step will be to ascertain how these molecules function in human beings.

Researchers at the University’s Centre for Discovery Brain Sciences have established a system to examine the complex interactions between immune cells at the site of spinal injury and how they contribute to the repair of damaged nerve connections in zebrafish.

“Zebrafish are interesting to us because they can regain full swimming ability after spinal cord injury,” said Professor Catherina Becker, of the University of Edinburgh’s Centre for Discovery Brain Sciences. “Our research is focused on understanding the factors involved in this process so that we can look for potential ways of developing treatments for people.”

The study was published in Nature Communications and funded by the Biotechnology and Biological Sciences Research Council.

RCVS carries out annual VN CPD audit

News Story 1
 The RCVS is carrying out its annual veterinary nurse CPD audit and has sent out requests for the CPD records of more than 1,100 nurses this week.

Under the RCVS Code of Professional Conduct, nurses are required to carry out at least 45 hours of CPD over a rolling three-year period. This year, 1,130 nurses have been asked to share their records from 2016-2018 to show that they have complied with the requirements.

Earlier this year, the VN Council decided to expedite the referral process for nurses who have not complied with the CPD requirement for three or more years. In such cases nurses will have their records sent to the CPD Referral Group.

Kew Gardens seeking vets for Ethnoveterinary Medicine Project

A new project at the Royal Botanical Gardens, Kew, is seeking the help of vets to find out how plants were traditionally used to treat animals.

The Ethnoveterinary Medicine Project is aiming to record the remaining knowledge from across the British Isles, before it disappears.

Visit the Kew Gardens website for more information or email ethnovet@kew.org to share data.
