WebAs a third line of defense, cell-mediated immunity—part of adaptive immunity—involves various types of cells that fight a specific pathogen and recognize antigens, which are molecules that trigger a response from the adaptive immune system, for example, surface proteins of bacteria or viruses. WebPlasma cells then release antibodies (also called immunoglobulins, or Ig). There are 5 classes of antibodies—IgM, IgG, IgA, IgE, and IgD.
