Induction and maintenance of the antibody response by different forms of human serum albumin.
Various forms of human serum albumin (HSA) were compared in their ability to induce and maintain the antibody response. In an in vitro model system, antibody synthesis was induced spontaneously during the maintenance phase of the immune response--presumably by persisting antigen. When different lymph nodes (LN) of the same rabbit were primed simultaneously with different forms of HSA, the spontaneous responses obtained in cell cultures prepared from LN primed with high molecular weight forms of HSA were greater than the responses obtained in cell cultures prepared from similar LN primed with lower molecular weight forms of HSA. This difference in response was consistent regardless of the method employed in antigen preparation and persisted for many months. The in vitro results indicating that the antibody response would be maintained at a higher level in animals immunized with high molecular weight forms of antigen and that the method of preparation would not be of major significance were confirmed in vivo in a mouse system.
