title: Regulatory structures on the V and C regions of immunoglobulin molecules.
abstract: As well as antibody-combining sites, an immunoglobulin (lg) molecule has several other structural features which permit it to bind to lymphoid cells, certain of their factors and other lg molecules. Here, Paolo del Guercio reviews these interactions and suggests that they help to regulate the production of lg molecules to extrinsic antigens and internal self structures.
