Rotavirus, the primary etiological driver of severe pediatric enteric inflammation in children under five years, instigates a clinical triad of projectile emesis, profuse secretory diarrhea, and electrolyte derangement. This fulminant pathophysiological trajectory precipitates hypovolemic shock and small intestinal brush border atrophy, mandating urgent parenteral rehydration—particularly in regions with fragmented healthcare infrastructure where case-fatality rates surge 20-fold absent intervention.

Taxonomically nested within Reoviridae, these non-enveloped pathogens (~70 nm diameter) encapsulate an 11-segment dsRNA genome within a triple-layered capsid. The outermost tier, critical for cellular invasion, incorporates two viral glycoproteins: VP4 (protease-cleaved spike) and VP7 (calcium-binding glycoprotein). These surface antigens govern the P/G genotypic classification system, with VP4’s hemagglutinin activity and VP7’s T-cell epitopes jointly directing strain-specific neutralizing antibody responses. Crucially, their antigenic drift facilitates evasion of humoral immunity despite vaccine-induced cross-reactive immunity.
While VP4/VP7-specific antibodies dominate neutralizing activity post-infection or live-attenuated vaccination, nonstructural proteins like NSP4 synergistically modulate enterotoxic effects. The intermediate capsid, composed of VP6 hexamers, exhibits conserved epitopes driving robust IgA/IgG responses—though whether these antibodies sterically hinder viral uncoating or simply mark recent exposure remains contentious. Recent crystallographic analyses reveal VP6’s metastable trimers undergo pH-dependent conformational shifts during endosomal escape, suggesting potential protective roles beyond serological biomarkers.
The protective response to rotavirus (RVA) infection and illness is now understood to involve both antibody-mediated and cell-mediated mechanisms, both of which are critical for resolving active infection and conferring future protection. The host's initial encounter with RVA primarily elicits a specific, serum-neutralizing antibody response. Subsequent infections, however, trigger a broader, more diverse response. In humans, local gut immunity, especially IgA antibodies, is crucial for protection. Furthermore, safeguarding children from rotavirus-induced diarrhea appears to be serotype-specific and linked to levels of neutralizing antibodies directed at matching viruses, with local IgA antibodies likely having a significant function.

Studies in germ-free pigs infected with HRV have revealed that those recovering from a severe HRV infection completely clear the virus upon re-exposure. The degree of protection in these pigs was positively related to the quantity of IgA antibody-secreting cells and B cell responses in the intestinal lamina propria. Mice serve as another experimental model for investigating RV infection. Murine RV can cause illness in mouse pups, but adult mice are resistant to RV diarrhea, only exhibiting viral shedding. In adult mice, the production of IgG and IgA antibodies, whether systemic or mucosal, is crucial for clearing rotavirus (RV) infections. Studies involving mice with different deficiencies in their immune systems have shown that various antibody-based and innate immune mechanisms work together to provide protection against RV infection. Administering virus-neutralizing antibodies orally presents a promising strategy for providing passive protection against gastrointestinal pathogens in both humans and animals. Investigations using immune bovine colostrum have shown that this preventive passive treatment markedly decreased the occurrence of RVA gastroenteritis outbreaks in children and the duration of RVA-associated diarrhea.
