Many long for a man’s most faithful friend, but as they approach him, they experience health complications instead of joy. Others avoid him with a big arc. This discomfort also has a name.
It is an unpleasant allergy accompanied by rhinitis, and this condition is associated with conjunctivitis, eczema, exhaustion and even bronchial asthma. All of this is caused by allergens found in the blood, skin, saliva, sweat, urine and skin scales of dogs.
However, scientists are working to make such allergy manifestations a distant memory and bring the first promising information! Experts say they are closer to a revolutionary goal – to create a vaccine against dog allergies. The portal informs about it Science Alert.
“Japanese scientists have been able to identify certain parts of the molecules that are likely to cause allergic reactions in humans when a dog appears near them.” writes Science Alert.
It is likely that they are finally on the trail of the dog allergy vaccine itself. Once they have identified and isolated these specific parts of the molecules, a team of experts can focus on a vaccine that will alleviate the responses of the immune system.
As the Science Alert further explains, these parts of the molecules are known as epitopy – the chains of amino acids that make up part of the protein and our body can begin to perceive them as a threat.
The researchers focused on a specific dog allergen called Can f 1. “It is one of seven such allergens that have been previously identified and are thought to be responsible for 50 to 75% of reactions in people allergic to dogs.” supplies the local portal.
These allergens can cause severe allergic reactions such as asthma, allergic rhinitis and in 5 to 10% of the population can cause allergic conjunctivitis.
However, the problem may be exacerbated. “As dog-to-human contact becomes more frequent and intimate, allergies are becoming more pronounced worldwide, especially in developed countries.” scientists accentuate.
The researchers examined the entire structure of the protein using a special technique Can f 1which no one has succeeded before.
Hope for others as well
If Japanese experts manage to develop a vaccine that turns with a hair allergy, it will be a hope for other allergy sufferers as well. Why? Epitopes are already mentioned behind everything.
“The development of this vaccine is by no means common, and if scientists succeed, there is hope that the same process could be used in the future to develop other types of vaccines.” concludes Science Alert.
