To determine whether RSV, pneumonia virus of mice, and influenza A virus similarly modify the respiratory allergic response during allergen provocation.
Sensitized and challenged BALB/c mice with ovalbumin (OVA), inoculating them with RSV, PVM, or influenza A virus during the challenge phase.
Assessed pulmonary inflammation, lung Th2 cytokine mRNA expression (IL-4, IL-5, IL-13), and serum IgE levels following the final allergen challenge.
PVM, like RSV, enhanced OVA-induced pulmonary IL-4, IL-5, and IL-13 mRNA expression and increased perivascular inflammation.
PVM promoted eosinophil influx into lung tissue, whereas influenza A virus suppressed Th2 cytokine mRNA expression while still augmenting pulmonary eosinophilic infiltration.

No takes yet. Share an insight, caveat, or question.

Implication

Animal study demonstrates that paramyxoviruses enhance allergic Th2 responses while influenza A decreases them in mice, indicating virus-specific mechanisms drive post-viral allergy exacerbation.
