Sydney : Scientists in Japan have identified the gene that triggers allergic reactions.
Some people are allergic to common allergens such as dust and pollen although sensitivities vary from person to person and it is possible to be allergic to just about anything.
Scientists at the RIKEN Research Centre for Allergy and Immunology at Yokohama used specially bred mice and found that they were resistant to stimuli normally capable of provoking severe allergic reactions, reported the online edition of News Australia.
Prior studies have established that allergens cause a build-up of calcium in what are called mast cells, located near the skin, kick starting the process that leads to rashes, sneezing, itching and swelling.
