Task: Intent Identification
Input (English): To demonstrate that in APPswe/PS1DeltaE9 transgenic mice, gene gun mediated Abeta42 gene vaccination elicits a high titer of anti-Abeta42 antibodies causal of a significant reduction of Abeta42 deposition in brain.', 'Gene gun immunization is conducted with transgenic mice using the Abeta42 gene in a bacterial plasmid with the pSP72-E3L-Abeta42 construct. Enzyme-linked immunoabsorbent assays (ELISA) and Western blots are used to monitor anti-Abeta42 antibody levels in serum and Abeta42 levels in brain tissues. Enzyme-linked immunospot (ELISPOT) assays are used for detection of peripheral blood T cells to release gamma-interferon. Immunofluorescence detection of Abeta42 plaques and quantification of amyloid burden of brain tissue were measured and sections were analyzed with Image J (NIH) software.', 'Gene gun vaccination with the Abeta42 gene resulted in high titers of anti-Abeta42 antibody production of the Th2-type. Levels of Abeta42 in treated transgenic mouse brain were reduced by 60-77.5%. The Mann-Whitney U-test P=0.0286.
