Could this jab stop allergies for good?
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.
