Fofinhos, espertos e encantadores, os gatos são, depois dos cães, os animais de estimação mais comuns. Contudo, muitas pessoas desenvolvem alergia a esses bichinhos, ficando com olhos lacrimejantes, coceira pelo corpo e espirrando o tempo todo. Agora, pesquisadores da School of Medicine at McMaster University, no Canadá, desenvolveram uma vacina que promete acabar com esses sintomas.
Cute, smart and charming cats are after the dogs, the most common pets. However, many people develop allergies to these pets, getting watery eyes, sneezing and itching in the body all the time. Now researchers at the School of Medicine at McMaster University in Canada developed a vaccine that promises to end with these symptoms.

Os cientistas descobriram uma molécula de proteína na pele dos gatos que causa a alergia. A partir dessa, identificaram regiões curtas dentro da proteína, que ativam as células T - células auxiliares que combatem a infecção - no sistema imunológico humano. Usando o código de aminoácidos da proteína total, os pesquisadores fizeram versões sintéticas dessas regiões e, em seguida, encontraram sete peptídeos. "Os peptídeos sintéticos se misturam para fazer a vacina. Nós escolhemos os peptídeos que iria trabalhar como em grande parte possível da população", diz Mark Larche, autor da pesquisa.
Scientists have discovered a protein molecule in the skin of cats that causes the allergy. From this, we identified short regions within the protein, which activates T cells - T helper cells that fight infection - the human immune system. Using the code of amino acids of the total protein, the researchers made synthetic versions of these regions and then found seven peptides. "The synthetic peptides are mixed together to make the vaccine. We chose peptides that would work in as much as possible of the population, " says Mark Larche, author of the study.
