摘要:The mouse thymus contains cells that synthesize and secrete minute amounts of immunoglobulin (Ig). These cells were studied by a combination of cytotoxic tests (with alloantisera prepared in congenic strains of mice) followed by pulse labeling of the surviving cell population with [3H]tyrosine. The immunoglobulin-synthesizing cells constitute less than 2% of the total cell population and are [theta] -, TL-, Ly-B-, Ig+, H-2+, and PC+. Since this phenotype is not characteristic of cells of the thymocyte lineage, the Ig+ cells are probably plasma cells and/or bone marrow-derived (B) lymphocytes. Similar studies of spleen cells indicate that immunoglobulin-synthesizing and secreting cells are [theta] -.
