Amyloid precursor protein processing and Aβ 42 deposition in a transgenic mouse model of Alzheimer disease Altered amyloid‐beta metabolism and deposition in genomic‐based beta‐secretase transgenic mice. Studies on the implication of this event in the propagation of AD are underway. Transgenic mouse technology has contributed much to our understanding of the function and dysfunction of the nervous system. Whereas most of these models are characterized by extensive amyloid plaque pathology, inflammatory changes and often behavioral deficits, modeling of neuron loss was much less successful. This book answers that question and many more, including what tests are available to discover an aberrant behavioral phenotype? Together they form a unique fingerprint. Transgenic mouse models have been used extensively to model the cognitive impairments arising from Alzheimer’s disease (AD)-related pathology. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. 33, 1024–1037 (2013). 2020 Dec 30;13(1):E117. 2003 Jul 31;39(3):409-21. Since the generation of the first AD transgenic mouse model in the mid-'90s, there has been an outburst of new transgenic animals, each showing AD-related phenotypes but failing to recapitulate crucial aspects of the disease, such as the extensive neuronal cell loss observed in postmortem tissue of AD patients. Abstract This study assessed the therapeutic utility of the autophagy enhancing stable disaccharide trehalose in the Tg2576 transgenic mouse model of Alzheimer's disease (AD) via an oral gavage of a 2% trehalose solution for 31 days. Conclusion: These data suggest that monomeric and oligomeric forms of Aβ and tau are secreted into serum via brain exosomes, most likely derived from astrocytes in the transgenic mouse model of AD with CAA. This Mini Review discusses the merits and shortfalls of transgenic (tg) rodents modeling aspects of the human Alzheimer’s disease (AD) pathology and their application to evaluate experimental therapeutics.
