Natural autoantibodies (NAAbs) are an important constituent of circulating immunoglobins. Some demonstrate polyspecific reactivity and high idiotypic connectivity. For example, they are reactive with DNA and cytoskeleton protein; others exhibit restricted binding specificity. Among several hypotheses, we have explored the possibility that NAAbs constitute a physiologic system in the organism that participates in the elimination of dead tissues and cellular debris by opsonization and phagocytosis.

UI MeSH Term Description Entries
D004905 Erythrocyte Aging The senescence of RED BLOOD CELLS. Lacking the organelles that make protein synthesis possible, the mature erythrocyte is incapable of self-repair, reproduction, and carrying out certain functions performed by other cells. This limits the average life span of an erythrocyte to 120 days. Erythrocyte Survival,Aging, Erythrocyte,Survival, Erythrocyte
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D001323 Autoantibodies Antibodies that react with self-antigens (AUTOANTIGENS) of the organism that produced them. Autoantibody
