    Elevated VEGF-A <t>and</t> <t>EDN1</t> associated with cerebral hypoperfusion in early-stage Alzheimer's disease. Concentrations of ( A ) VEGF-A and ( B ) EDN1, measured by sandwich <t>ELISA,</t> in Braak tangle stage groups BS0–II, BSIII–IV and BSV–VI, across brain regions. Each data-point represents the average of a duplicate measurement in a single brain region. Z -scores were calculated to combine data from two independent cohorts. Mean ± standard error of the mean are shown. Correlation analysis between ( C ) VEGF-A and ( D ) EDN1 with the MAG:PLP1 ratio in the different brain regions. Solid linear regression lines are used to indicate brain regions with significant correlations, dashed lines indicate brain regions with non-significant relationships. Trigone is not shown as it did not fit within the range of the graph. * P < 0.05, ** P < 0.01, *** P < 0.001 indicate statistical strength of correlations within respective brain regions.

    Techniques Used: Sandwich ELISA

    Mediators of angiogenesis are dysregulated in early-stage/intermediate pathology Alzheimer's disease. ( A and B ) Levels of endoglin (CD105), a marker of neoangiogenesis, measured first using the angiogenesis proteome profiler and then independently by commercial ELISA kit.

( C and D ) Levels of pro-angiogenic ( C ) and anti-angiogenic ( D ) mediators in early-stage/intermediate pathology [Braak tangle stage (BS) III–IV] (blue) and late-stage AD (BSV–VI) (red), relative to the levels in minimal pathology BS0–II cases.

    Article Snippet: The EDN1 level was measured using a commercially available ELISA kit (QET00B, R&D systems), as reported previously., Brain tissue homogenates were diluted 1:50 in assay diluent and 100 μl was added to the plate in duplicate.

    Techniques: Marker, Enzyme-linked Immunosorbent Assay
