Immuglobulin A (IgA) is an antibody that plays a crucial role in mucosal immunity.
Chronic fatigue syndrome[edit | edit source]
A study of 128 ME/CFS patients found significantly increased IgA response to lipopolysaccharides (LPS) from the cell walls of commensal bacteria. Increased IgA response was associated with increased serum IL-1, TNFα, neopterin and elastase. The study concluded that increased translocation of commensal bacteria may be responsible for the disease activity in some ME/CFS patients.

antibody - Antibodies or immunoglobulin refers to any of a large number of specific proteins produced by B cells that act against an antigen in an immune response.
chronic fatigue syndrome (CFS) - A fatigue-based illness. The term CFS was invented invented by the U.S. Centers for Disease Control as an replacement for myalgic encephalomyelitis (ME). Some view CFS as a neurological disease, others use the term for any unexplained long-term fatigue. Sometimes used as a the term as a synonym of myalgic encephalomyelitis, despite the different diagnostic criteria.
