New Class of Effective Drugs on the Anvil for Asthma and Allergy
The researchers found an important target that holds significant promise for millions of people suffering from allergies, asthma, rheumatoid arthritis
and a range of other inflammatory diseases.
The study showed that a key component of the body’s own response to allergy-causing agents (allergens) can be targeted to reduce allergic reactions in mice.
In the study, the researchers found that by targeting a molecule called p110delta it is possible to interfere in the allergic reaction before symptoms occur, and without shutting down the immune system.
p110delta is a member of a family of eight proteins called PI3Ks, which control important biological functions. Their activity is implicated in many different diseases including cancer, and they are an important target for drugs.
However, drugs that act on all PI3K family members tend to be toxic in the body. For this reason the researchers used genetic techniques to find out which PI3K family members are linked to specific diseases.
By gaining a better understanding of each PI3K researchers hope to target drugs more specifically and reduce the potential for side effects.
The p110gamma member of the PI3K family had earlier been implicated in allergic reactions and was thought to be more important than p110delta.
However, in the current study, it has been confirmed that p110delta, but not p110gamma, is important for allergic reactions in a mouse model.
