In a person with allergic reactions, the body has grown to be hypersensitive to innocent substances. It’s include pollen and grass, so the immune system need to deal with them as if they are pathogens. Hypersensitivity in the attention is called allergic conjunctivitis and it can range from mild to critical. While an allergen comes into touch with the attention. It binds to the antigen molecules on the surface of the mast cells Histamine. Then turns on particular itch nerve cells by binding to histamine receptors at the surface of those cells. Scientists are still uncertain about how precisely this works. But a whole lot progress has been made in recent years to similarly our know-how of the mechanism and biological motive of itch.
Signals travel to the brain
What is known today about the science of itch comes mostly from studies on skin. Here, the purpose of itch is thought to be to encourage us to scratch.
