APP transgenic mice: the effect of active and passive immunotherapy in cognitive tasks.

摘要

Various immunotherapy strategies for APP transgenic mice have emerged in recent years. Specifically, active immunization with beta-amyloid (A beta) or passive immunization with anti-A beta-antibodies in APP transgenic mice has appeared most promising. Recent studies have shown that treatment of APP transgenic mice either with A beta(40/42) or A beta-specific antibodies can have beneficial effects in cognitive tasks. Active as well as passive immunization have been shown to affect spatial, non-spatial, emotional and object-related learning and memory. Such effects can be observed when treatments are applied prophylactically (before apparent A beta pathology) or therapeutically (after the development of A beta pathology) in APP transgenic mice. This review focuses on such cognitive outcomes of different active and passive immunization strategies in APP transgenic mice.
