The functional significance of the nonstructural proteins NS1 and NS2 remains unclear.
The concept that IgE might be involved in the pathogenesis of RSV disease has been suggested by a number of studies , , Phase 1 study of intravenous ribavirin treatment of respiratory syncytial virus pneumonia after marrow transplantation. Admission locations were as follows: RSV-induced chemokine expression in the lower airways: Second, newborns and very young infants may not mount a protective immune response because of relative immunologic immaturity or because of suppression of their immune response due to circulating maternally derived anti-RSV antibodies 31 , 47 , The observation that RSV-infected epithelial cells upregulate and secrete eosinophil chemoattractants supports the hypothesis that eosinophils are recruited to and participate in the immunopathogenesis of RSV disease. Both serum and secretory antibodies are produced in response to RSV infection, even in very young infants ,
While the immunopathologic mechanisms associated with enhanced RSV disease following vaccination with the inactivated vaccine are compelling and the involvement of bronchiolktis system-mediated components in the pathogenesis of RSV bronchiolitis and pneumonia is likely, it is important to emphasize that much of the damage is probably a result of direct cytotoxicity.

This is under respiratory system. It is the tropism of this agent for respiratory epithelium and its propensity to induce the formation of large syncytia that give this virus its name Fig.
Role of Cell-Mediated Immunity The most dramatic support for an immunopathologic mechanism in RSV disease emerged from field studies where infants were immunized with a formalin-inactivated, alum-precipitated, parenterally administered RSV vaccine. However, some studies have demonstrated that virus shedding stops coincident with the emergence of specific secretory immunoglobulin A IgA at the time of clinical recovery Use proper hand hygiene and avoid contact….
While the mechanism of action of its antiviral properties remain unknown, the reversal of the in vitro antiviral activity by guanosine or xanthosine that suggests ribavirin may act as an analogue of these cellular metabolites.

Another important consideration in the development of an effective RSV vaccine is the need to provide protection against multiple antigenic strains of RSV in the two major groups, A and B. Enhancement of respiratory syncytial virus pulmonary pathology in cotton rats by prior intramuscular inoculation of formalin-inactivated virus.
Many details of the immunology and immunopathologic mechanisms of RSV disease known at present have been learned from rodent models of RSV disease and are quialet in some detail. Additional practical bronchlolitis associated with monthly administration of this preparation during RSV season include the necessity for intravenous access, long infusion times which can strain hospital resourcesand high cost.

A number of strategies have been implemented recently to generate safe and effective subunit, inactivated, and live attenuated virus vaccines The early observations that severe RSV disease is most likely to occur in infants between 2 and 6 months of age, when maternally derived anti-RSV neutralizing antibodies persist at high concentrations, prompted investigators to consider the involvement of anti-RSV antibodies in immunopathologic mechanisms in RSV bronchiolitis 2021 Parenteral administration of RSV-neutralizing antibodies in animal models and, more recently, in high-risk infants resulted in prevention of RSV disease.
