Abstract
Summary
A substantial proportion (47%) of apparently healthy old mice possessed significantly greater numbers of spleen cells capable of autoimmune hemolytic plaque production than did middle-aged or young adult mice of the same genotype. The average plaque counts obtained with old (C57B1/ 10 X B10.LP)F1 male mice 4 to 5 times higher than those obtained with comparable younger mice. This evidence supports earlier suggestions of a meaningful association between autoimmunity and aging.
