Anti-Aβ antibodies in serum detected with ELISA. A. Anti-Aβ1-15 antibodies were in highest levels among the epitopes in both AD (n=53) and NC (n=60) groups. B. Distribution patterns of Aβ1-15 antibodies in AD (n=53) and NC (n=60) groups and its levels are significantly lower in AD than NC groups (p < 0.02). C. Age-associated Aβ1-15 antibody reduction in AD patients in 66-75 years of age (n = 27) compared with those of 55-65 (n = 8) or 76 - 89 (n = 19) years of age (p = 0.03 and 0.08 respectively). No age-related differences in NC among 66-75 (n = 30) than 55-65 (n = 19) and 76-89 (n = 11) years old subjects (p = 0.9). D. Isotyping ELISA showed that IgG2 was the major isotype of Aβ1-15 antibodies among IgG1-3. Shown are Mean ± SE.
