27] Secretory immunoglobulin A (IgA) A is the predominant Immunoglobulin in mucosal secretions.
The evidence that exhaustive exercise may compromise the immune response is mainly confirmed by upper respiratory tract infections which are probably related to the decrease in secretory immunoglobulin A in the upper airway mucosa and/or profile changes of systemic cytokines as well as local cytokines of the upper respiratory tract.
The new system, which consists of a lab-on-a-chip, laser-induced fluorescence detection device and analysis method based on antigen-antibody reaction and electrophoresis, can rapidly measure stress-related substances secretory immunoglobulin A (S-IgA) and cortisol in salivary samples.
