[Relationship between dose of injected serum albumin and appearance of cells synthesizing immunoglobulins or antibodies].

Mice were given increasing doses of sheep serum albumin emulsified with Freund's complete adjuvant in hind footpads. The kinetics of development of cells which synthesize antibody or immunoglobulins without antibody function was studied in the draining lymph nodes. Results show the relationship between the two cell populations: as the number of antibody synthesizing cells increased, the number of immunoglobulin synthesizing cell increased, and conversely. Between 0.050 and 2.5 mg of antigen, the number of cells of each population increased with the dose injected whereas with 5 and 10 mg, this number is smaller than that obtained with smaller doses and decreased with an increasing dose.
