Respiratory syncytial virus (RSV) is the most important cause of severe, lower respiratory tract infections in infants, and RSV infections have been associated with chronic wheezing and asthma during childhood. However, the mechanism of RSV-induced airway inflammation and airway hyperresponsiveness (AHR) is poorly understood. Furthermore, there are(More)
This study aimed to determine whether the protective effects of the Mycobacterium bovis Bacillus Calmette–Guérin (BCG) vaccination on allergic asthma are associated with the T helper (Th) 17/Th1 balance in a murine asthma model. BALB/c neonates were vaccinated with BCG on the first day after birth, sensitized with ovalbumin, and then challenged with(More)
Respiratory syncytial virus (RSV) causes respiratory tract infection, particularly acute lower respiratory tract infection (ALRTI), in early childhood. The RSV fusion protein (F protein) is an important surface protein, and it is the target of both cytotoxic T lymphocytes (CTL) and neutralizing antibodies; thus, it may be useful as a candidate for vaccine(More)
The human bocavirus 1 (HBoV1) parvovirus causes respiratory disease and primarily affects children. Despite its worldwide prevalence, the mechanisms of HBoV1 replication and pathogenesis remain largely undefined. In this study of 846 children hospitalized at the Children's Hospital of Chongqing Medical University in China for respiratory tract infection(More)
BACKGROUND Regulatory T cells (Treg cells), which are essential for regulation of immune response to respiratory syncytial virus (RSV) infection, are promoted by pharyngeal commensal pneumococcus. The effects of pharyngeal microflora disruption by antibiotics on airway responsiveness and relative immune responses after RSV infection have not been clarified.(More)
Multiple sclerosis starts with increased migration of auto-reactive lymphocytes across the blood-brain barrier, resulting in persistent neurodegeneration. Clinical and epidemiological studies indicated upper respiratory viral infections are associated with clinical exacerbation of multiple sclerosis. However, so far there is no any direct evidence to(More)
