ASTHMA WITH­OUT ASTHMA?

Friday - - HEALTH NEWS -

Re­searchers in the United States have iden­ti­fied a pro­tein that may be caus­ing asthma-like cough­ing and wheez­ing in chil­dren, with­out those kids hav­ing any kind of al­lergy to trig­ger the dis­ease. The World Health Or­ga­ni­za­tion es­ti­mates around 235 mil­lion peo­ple suf­fer from asthma world­wide; the dis­ease is of­ten linked to al­ler­gies, such as a re­ac­tion to dust, pollen, smoke or pol­lu­tion. The new study found that the pro­tein TRPV1 – tran­sient re­cep­tor po­ten­tial vanil­loid 1, a pro­tein that plays a role in air­way dis­ease through mu­cus pro­duc­tion, cough re­flex stim­u­la­tion and air­way nar­row­ing – may also be re­spon­si­ble for asthma-like symp­toms in chil­dren even in the ab­sence of al­ler­gies. By un­der­stand­ing bet­ter the mech­a­nism by which these chan­nels are reg­u­lated, the chan­nels can then be tar­geted with a new gen­er­a­tion of mol­e­cules and new drugs to con­trol cough and wheez­ing in child­hood.
