title: The immune response of the mouse to lymphocytic choriomeningitis virus. IV. Enumeration of antibody-producing cells in spleens during acute and persistent infection.
abstract: The solid-phase immunoenzymatic technique for the enumeration of single rat cells producing antibodies against ovalbumin has been adapted to mouse cells producing antibodies against lymphocytic choriomeningitis (LCM) virus. After intravenous (i.v.) infection with 10(3) infectious units, IgM- and IgG-producing cells appeared on days 4 and 5, respectively. They rose to high numbers on days 7, 8, and 9 and were still detectable on day 38. After a second i.v. inoculation of 10(7) infectious units, antibody-producing cells (APC), most of which made IgG, appeared faster and reached much higher numbers. Mutatis mutandis, very similar results were obtained with mice inoculated with vesicular stomatitis virus. Antibodies were specific as to virus, but probably corresponded to more than one viral antigen. Relatively low numbers of APC were also detected in the spleens of NMRI strain carrier mice, which develop severe immune complex disease in later life, but not in spleens of persistently infected young mice of strains that remain free of late immune complex disease, namely CBA/J, C3H/HeJ, and gray house mice; APC were detected in spleens of aging CBA/J but not gray house mice.
