Could this jab stop al­ler­gies for good?

Irish Daily Mail - - Good Health -

SCI­EN­TISTS at the Univer­sity of Queens­land say a jab could soon of­fer life-long pro­tec­tion from se­vere al­ler­gies such as asthma.

The jab is a form of gene ther­apy, where a healthy gene is in­jected to re­pair a faulty im­mune re­sponse. Re­searchers say in many cases of al­lergy, symp­toms re­sult from im­mune cells called T-cells re­act­ing to pro­teins in the al­ler­gen; these cells re­tain the ‘mem­ory’ to re­act again.

In the study, mice were in­jected with a healthy gene that reg­u­lates al­ler­gen re­sponses; this ‘wiped’ the T-cells’ mem­ory, so the im­mune sys­tem tol­er­ates the pro­tein, ac­cord­ing to the jour­nal JCI In­sight.
