Shetland ponies help allergy sufferers
Shetland
“To our knowledge, this is the very first study of a natural allergic disease in which we can show that immune responses to allergens can take two directions."

Horse immune system acts in two different ways in response to midge bites

Shetland ponies are helping researchers understand how people could be prevented from developing allergies, according to a new study.

Researchers at the University of Edinburgh said that the horse immune system responds to midge bites in a way that prevents, rather than triggers, allergic reactions.

The study of Shetland ponies found that their immune system acts in two different ways in response to midge bites.

One of these responses triggers allergy symptoms, such as itching and inflammation, while the other prevents an allergic reaction.

The team found that after being exposed to midges, the horse immune system releases various types of factors, known as cytokines, which affect the behaviour of other cells.

Ponies that react to midge bites release cytokines, known as IL-4, which trigger allergy symptoms.

In ponies not sensitive to bites, another cytokine, INF-g, is released, blocking different immune cells that would otherwise trigger allergic reactions.

The researchers say that by priming the human immune system to respond to allergens in a way that does not trigger reactions, it could be possible to prevent people developing allergies.

Lead author of the study, Dr Dietmar Zais from the University of Edinburgh's School of Biological Sciences, said:  “To our knowledge, this is the very first study of a natural allergic disease in which we can show that immune responses to allergens can take two directions, either leading to allergy or to tolerance.

"We believe this finding could have direct practical implications, for example by helping immune responses to choose the 'right' direction in individuals who we would like to protect from developing occupation-associated allergies.”

The study, published in the journal PLOS ONE, was funded by the Dutch Foundation for Technical Sciences (STW) and was carried out in collaboration with researchers in the Netherlands.

Vets to run marathon for World Animal Protection

News Story 1
 Two recently graduated veterinary surgeons will be running the London Marathon in April to raise money for the charity World Animal Protection.

Alex Bartlett and Maeve O'Neill plan to run the race together if they are given the same start times.

Dr O'Neill said: "You're always limited in what you can do to help animals, so it is nice to raise money for a charity that helps animals around the world."

Dr Bartlett added: "I have never run a marathon before and am excited to run my first one for such a good cause!"

Both Dr Bartlett and Dr O'Neill have fundraising pages online.

BSAVA releases new Guide to Procedures

The British Small Animal Veterinary Association (BSAVA) has published a new edition of its Guide to Procedures for Small Animal Practice.

It has added four new procedures; cystostomy tube placement, endotracheal intubation, point-of-care ultrasound and wet-to-dry dressings.

BSAVA says that it is an essential step-by-step guide to diagnostic and therapeutic procedures performed in practice. The textbook includes new images and illustrations, as well as high-definition videos for use prior to procedures.

Nick Bexfield and Julia Riggs, editors of the new edition, said: "We have built upon the success of the previous editions by responding to the feedback received from the BSAVA readership, and hope this new guide helps to further increase the confidence and accuracy with which these procedures are performed."

Print copies are available in the BSAVA store, with a digital version in the BSAVA library.
