Prevention & Treatment of Viral Infections


Cohort studies have identified viral infections occurring against a background of allergic sensitization to aeroallergens. A combination of recent experimental and human studies have suggested that underlying this bipartite process are a series of interactions between antiviral and atopic inflammatory pathways.

These pathways are mediated by local activation of myeloid cell populations in the airway mucosa and the parallel programming and recruitment of their replacements from bone marrow.

Targeting key components of these pathways

at the appropriate stages of asthma provides new opportunities for the treatment of established asthma but, more crucially, for primary and secondary prevention of asthma during childhood.
