Peanut allergy vaccine tested in rats

Peanut allergy vaccine tested in rats

On Wednesday (11) it was reported in the Journal of Allergy and Clinical Immunology, a study by researchers at the University of Michigan, USA, who developed a vaccine that could end peanut allergy.

The experiment was performed with mice, which received three monthly doses of a nasal vaccine to protect them from allergic reactions after peanut exposure. The vaccine was developed during two decades of study.

Most allergies occur when the immune system "recognizes" a food as an attacker to be attacked, that is, as if the peanut was a virus.

The aim of the researchers with the study is to understand how immune cells responded to peanuts in allergic rats. In this way, they could develop a new immunotherapy that could alter the immunological reactions to foods.

According to the research, the laboratory mice that participated in the test have the same symptoms of allergy of humans, including itchy skin and difficulty breathing. Studies are underway to determine the duration of the vaccine. However, the researchers believe the protection will last and will continue to follow the guinea pigs. Although studies in mice are still ongoing, the next step is to evaluate the effectiveness of the vaccine in humans.

What is Food Allergy?

Food allergy is a reaction of the immune system that occurs soon after ingestion of food. Even a small amount of the food that causes allergy in some people can trigger signs and symptoms, which often vary in severity. In some cases, food allergy can cause severe symptoms or even a life-threatening reaction - known as anaphylaxis. Understand the problem here!

Brazil studies classification of syndromes linked to Zika

Brazil studies classification of syndromes linked to Zika

Identifying babies who were not born with microcephaly but who have problems related to Zika virus are the challenge for Brazil to provide assistance to all affected children, according to the director of the Department of Epidemiological Surveillance of the Ministry of Health, Eduardo Hage Carmo. According to the Ministry, from 13% to 19% of the children examined have a false negative result, that is, they do not have a perimeter of the head smaller than standard, characteristic of microcephaly, as they develop other consequences attributed to Congenital Syndrome Associated with Infection by Zika virus.
