UNLABELLED In the field of athletics, acupuncture has been used for treatment of injury, reduction of fatigue and management of physical condition. However, there is little information on the effect of acupuncture on the immune function in response to exercise. PURPOSE The aim of this study was to examine the effect of acupuncture treatment on the mucosal immune function after a single period...

This study examined whether cardiorespiratory fitness (CRF) and body composition are associated with salivary secretory immunoglobulin A (SIgA), a mucosal immunity marker, and salivary alpha-amylase (sAA), a marker of stress-related sympathetic nervous system (SNS) activity, in South African children. Morning (7:30-8:00 a.m.) saliva samples were collected from 132 children (10.05 ± 1.68 years o...

Streptococcus pneumoniae, also known as the pneumococcus, contains several surface proteins that along with the polysaccharide capsule function in antiphagocytic activities and evasion of the host immune system. These pneumococcal proteins interact with the host immune system in various ways and possess a wide range of biological activities that suggests that they may be involved at different s...

Pneumococcal surface protein C (PspC) binds to both human secretory immunoglobulin A (sIgA) and complement factor H (FH). FH, a regulator of the alternative pathway of complement, can also mediate adherence of different host cells. Since PspC contributes to adherence and invasion of host cells, we hypothesized that the interaction of PspC with FH may also mediate adherence of pneumococci to hum...

THE AIM OF THIS STUDY WAS to describe typical training load (TL) carried out by a professional female futsal team for a period of 5 weeks; and to verify the relationship between TL, stress symptoms, salivary secretory immunoglobulin A (SIgA) levels, and symptoms of upper respiratory infections (URI). Over 45 sessions, the TL of the athletes was monitored daily by means of session-RPE method dur...

There is growing evidence that strains of Mycobacterium tuberculosis differ in pathogenicity and transmissibility, but little is understood about the contributory factors. We have previously shown that increased expression of the principal sigma factor, SigA, mediates the capacity of M. tuberculosis strain 210 to grow more rapidly in human monocytes, compared with other strains. Strain 210 is p...

INTRODUCTION Both reactive arthritis (ReA) and undifferentiated spondyloarthritis (uSpA) belong to the group of autoinflammatory diseases called spondyloarthritis (SpA). Hypotheses have been proposed about a relationship between the intestinal mucosa and inflammation of joint tissues. The role of immunoglobulin IgA or secretory immunoglobulin A (SIgA) in the inflammatory and/or clinical activit...

Background: Little is known about pulmonary complications induced by Sulfur Mustard (SM), as a chemical warfare agent,especially considering its long term effects. The present study was carried out to investigate the association of α1-antitrypsin(A1AT), Complement component C5a, and Secretory Immunoglobulin A (sIgA) with long-term pulmonary complications on SMexposedindividuals, 20 years after ...

Purpose The purpose of this study was to evaluate mechanisms controlling secretory IgA (SIgA) production, thereby ensuring maintenance of ocular surface health. Methods To determine whether the presence of specific gut commensal species regulates SIgA levels and IgA transcripts in the eye-associated lymphoid tissues (EALT), specific-pathogen-free (SPF) Swiss Webster (SW) mice were treated wit...

An in vitro mucus assay was developed to study the role of mucus gel and secretory immunoglobulin A (sIgA) in preventing attachment of Campylobacter jejuni to INT 407 cells. An overlay of rabbit small intestinal mucus was found to impede the attachment of C. jejuni to a monolayer of INT 407 cells. Mucus from rabbits previously colonized with C. jejuni was found to completely inhibit bacterial a...
