Furthermore, while the retention of antibody-mediated functional responses, despite the waning of neutralization, has been demonstrated in the blood, its potential at the mucosal surface remains understudied [7]. Pre-existing vaccine-induced immunity may also modulate immune responses … WitrynaAn antibody, also known as an immunoglobulin (Ig), is a protein that is produced by plasma cells after stimulation by an antigen. Antibodies are the agents of humoral immunity; they are the weapons the B cells use in their attacks on pathogens. Antibodies occur in the blood, in gastric and mucus secretions, and in breast milk.
