The Epstein-Barr virus is one of the most common and persistent human viruses in the world, according to the CDC.

The most abundant type of antibody in our intestine is immunoglobulin A (IgA) which, once released, recognizes, and binds specific gut bacteria. On average, about 35% of the gut bacteria are ...

A new study of more than 150 COVID-19 patients shows that IgA antibodies dominate the early response to the SARS-CoV-2 virus, coming on more quickly and strongly than IgG and IgM antibodies.

IgA antibodies are the second-most common antibody family and form a core component of responses in the adaptive immune system, the portion of the immune response dominated by B cells and T cells.

Scientists found that this bacteria would strip IgA antibody of its sugar in mice altered to carry human immune genes and in human cells grown in the lab, leaving the antibody in the same form ...

One group, who had IgA antibodies only, never succumbed to COVID-19. Participants in the other group had both IgG antibodies and T cells, and contracted the disease.

Antibodies to erythrocytes or leukocytes could not be found, but a precipitating antibody reactive with IgA in donor and normal human serum was discovered in the patient's serum.
