Rhinovirus Infects B and CD4 T Lymphocytes in Hypertrophic Tonsils in Children.

ABSTRACT: Prolonged detection of rhinovirus (RV) in secretions after a typical cold and asymptomatic shedding are frequently reported. Although RV has been detected in human hypertrophic tonsils, its replicative status and host cell range remain unclear. In this study, we analyzed RV replication, infected cell types, and recovery of infectious virus in adenoids, palatine tonsils, and respiratory secretions from 293 children with tonsillar hypertrophy undergoing tonsillectomy. Samples were screened by real-time RT-PCR, and RV-positive samples were analyzed using immunohistochemistry (IHC), chromogenic in situ hybridization (CISH), flow cytometry, and RV isolation in cell culture. RV genotypes from species A, B, and C were identified in adenotonsillar samples. RV antigenome and structural proteins wer
