The soluble somatic antigens of Syngamus trachea were studied by gel electrophoresis and by immunoelectrophoresis, including staining for enzyme activity. Rabbit antiserum prepared by repeated injections of parasite material was used to demonstrate the antigens. Serum obtained after 12-15 weekly injections produced up to 16 precipitation arcs with the S. trachea preparation. Two of the arcs represented reactions against contaminating host material, and enzyme activity was detected in seven arcs. Cross reactions occurred with extracts of Trichinella spiralis (two arcs) and Ascaris lumbricoides (one arc).

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Antibody Structure

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Hypersensitivity Reactions: Immune-Complex Reactions

Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
