RSV encodes eleven separate proteins, including structural proteins such as membrane envelope glycoproteins (F and G), two non-structural proteins 1 and 2 (NS1 and NS2), and matrix proteins (M), which are considered crucial pathogenic agents to stimulate airway hyperreactivity (AHR), such as Th2-type overexpression, cytokines immune disorder, and inflammatory disequilibrium [96–98]. The gene discussed is PROS1; the disease is immune system disorder.
