The process of immunological BcellBcell maturation involves transformation from an undifferentiated Bcell to one that secretes antibodies with particular specificity ref Nossal, G. J. V. & Lederberg, J. 1958. Antibody production by single cells. Nature 181 1419 1420 ref . This differentiation and activation of the Bcell occurs most rapidly after exposure to antigen by antigen presenting cell s in the reticuloendothelial system reticuloendothelial system, and under modulation by T cell s, and is closely intertwined with affinity maturation . Bcell s that respond most avidly to antigen are preferentially allowed to proliferate and mature, a process known as clonal selection . In lymphocyte lymphocytic neoplasm neoplastic diseases such as multiple myeloma and lymphoma , but also other illnesses, there can be a massive expansion of a single Bcell clone, detectable by measuring the excessively produced antibodies, measured in a serum protein electrophoresis test or peripheral blood flow cytometry . Such an expansion is said to be monoclonal , and monoclonal antibodies produced by such a group of B cells can cause illnesses such as amyloidosis and systemic lupus erythematosus lupus , or can be indicative of an underlying malignancy .
