Characterization of an idiotype-binding helper cell required for the formation of timothy grass pollen
Experiments were conducted using an excess of biosynthetically labeled timothy grass pollen antigen-B-specific (AgB-specific) T helper factor (THF) with enriched T cells, enriched B cells, or normal spleen cells to determine the site of the THF action. These studies indicated that the labeled THF bound preferentially to T cells, and analysis of the cell surface characteristics suggested that these T cells were Lyt 123+ cells. A panning technique using partially purified AgB-specific THF-coated Petri dishes depleted a population of idiotype-binding T cells that appears to be required for the formation of AgB-specific IgE antibody.

Antibody Structure
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.

Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
Antigens Involved in Adaptive Immunity
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.
T Cell Activation and Clonal Selection
Naive T cells that have not yet encountered an antigen express two primary CD...
B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
