Elevated iron and zinc in Alzheimer hippocampus: A postmortem study using neutron activation analysis

concomitant AD pathology. Findings that TL is shorter even in substantially non-mitotic brain tissue suggests that telomere shortening might in part be an innate feature of individuals, either owing to congenitally shortened telomeres, or an inherited tendency for reduction in telomere length. Additional experiments examining longitudinal decline in blood leukocyte DNA may be able to further clarify the degree to which telomere length is environmental or acquired versus innate.
