• An antibody, SIgA, found in breast milk alters the kinds of bacteria that colonize the infant gut. • The SIgA antibody also appears to change “turn on” and “turn off” genes involved in the rapid growth of the intestines that is normal in early life, as well as genes specifically linked to intestinal bowel disease. • These findings suggest a potential new role for the antibody in treating bowe...
The concept of a common mucosal immune system in man was tested by examining the concurrent presence of specific-secretory IgA (SIgA) antibodies in human milk and saliva from three groups of subjects: 64 Sri Lankan women living in Sri Lanka; 20 immigrant Asian women living in Birmingham (median duration of residence in the United Kingdom five years); and 75 Caucasian women living in Birmingham ...
Athletes engaged in strenuous training might experience transient immune suppression that could lead to greater incidence of upper respiratory tract infections (URTI). Since interleukin 21 (IL-21) stimulates immunoglobulin A (IgA) secreting cells and a low level of this immunoglobulin is associated with increased incidence of URTI, the aim of the present study was to investigate the effect of a...
This study examined relationships among physical activity, body composition, and stress- and immunity-related variables in fifth grade children (10-11 yr) in Southern Ontario. The 29 boys and 32 girls, who participated in the study, performed a 20-m shuttle run for prediction of aerobic fitness. Bioelectrical impedance was used to assess relative body fat. Standardized questionnaires were used ...
Lactobacillus paracasei K71 was shown to be effective in alleviating the severity of atopic dermatitis in a randomized controlled trial, and a preliminary open-label trial suggested that strain K71 intake enhanced secretory immunoglobulin A (sIgA) release in the saliva. This study investigated the effect of K71 on sIgA release in a randomized, double-blind, placebo-controlled, parallel-group tr...
BACKGROUND Early Childhood Caries (ECC) is one of the most common chronic childhood diseases. In spite of the global decrease in dental caries in the past decades, ECC has become a significant problem in many developing countries and also in a few industrialized nations. Saliva as a host factor can play an important role in the process of dental caries. OBJECTIVE The aim of this study was to ...
BACKGROUND Saliva contains a number of protective factors such as mucins, immunoglobulins (e.g., IgA, IgG, and IgM), and enzymes (e.g., lysozyme and lactoperoxidases) that play an important role in the maintenance of oral health. The aim of this study was to compare levels of sIgA, histatin-5, and lactoperoxidase in saliva of adolescents with dental caries. MATERIAL AND METHODS Thirty-five ad...
A Emenda Constitucional nº 19/98 incluiu o Princípio da Eficiência no art. 37 Constituição Federal, sendo de observância obrigatória pela administração pública. Além disso, diante tendência redução contingente, sem perspectivas mudança, é fundamental que gestor polícia conheça e aplique metodologias qualifiquem emprego do seu efetivo. O objetivo deste estudo apresentar a aplicação Sistema Geren...
Secretory immunoglobulin A (SIgA) enhances host-microbiota symbiosis, whereas SIgM remains poorly understood. We found that gut IgM+ plasma cells (PCs) were more abundant in humans than mice and clonally related to a large repertoire of memory IgM+ B cells disseminated throughout the intestine but rare in systemic lymphoid organs. In addition to sharing a gut-specific gene signature with memory...
26 Understanding psychological factors that affect immunity in sport might help to reduce 27 infection risk in athletes. The present study examined within-person changes and individual 28 differences in perceived coach control, intentions to drop-out, and saliva secretory 29 immunoglobulin A (SIgA). Thirty-two field hockey players completed questionnaires and 30 provided saliva samples over a t...
