Equine Immunoglobulin A (IgA) is a critical antibody isotype found in mucosal secretions, such as saliva, respiratory and gastrointestinal secretions, as well as in serum. IgA plays a central role in the immune defense of horses by neutralizing pathogens at mucosal surfaces, preventing their adherence and invasion, and modulating immune responses to maintain mucosal homeostasis. Changes in IgA levels can reflect immune system activity, mucosal health, or responses to infection, vaccination, and inflammatory conditions, making it a valuable biomarker for both systemic and local immune function in horses.
Horse IgA ELISA (enzyme-linked immunosorbent assay) enables the sensitive and specific measurement of IgA concentrations in serum, plasma, or mucosal secretions. In research settings, this assay is used to study equine immunology, including vaccine responses, mucosal immunity, and the role of IgA in infectious diseases or allergic conditions. It is also employed in comparative studies to understand immune mechanisms and monitor immune modulation in experimental therapies.
In clinical settings, horse IgA ELISA can assist in evaluating immune status, diagnosing immunodeficiencies, or monitoring recovery from infections and inflammatory diseases. It is particularly useful for assessing mucosal immune responses in respiratory or gastrointestinal conditions and for guiding vaccination strategies. Monitoring IgA levels over time can help veterinarians assess disease progression, treatment efficacy, or the overall health of the equine immune system.
