Importantly, the mice live normally, in contrast to previous APP overexpression-based models which are aggressive and often die of unknown cause(s).<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<table width=\"700\">\n<tbody>\n<tr>\n<td style=\"border: 5px; background-color: #ffffff; text-align: left; white-space: normal; text-indent: 1em;\" valign=\"top\">Alzheimer&#8217;s disease (AD), which is the major form of dementia, is a syndrome caused by a number of progressive illnesses that affect memory and cognitive capacity. The number of people living with dementia worldwide is estimated at 44 million, and is set to almost double by 2030 if preventive therapies are not found [1]. Researchers have generated a number of transgenic (Tg) mouse models that overexpress human \u03b2 amyloid (A\u03b2) precursor protein (APP); however, these APP-Tg mice showed artificial phenotypes that may have little to do with the human disease.<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 5px; background-color: #ffffff; text-align: left; white-space: normal; text-indent: 1em;\" valign=\"top\">\n<p align=\"left\">Takaomi C. Saido, Takashi Saito, and colleagues at RIKEN Brain Science Institute generated <i>App<\/i> knock-in mice with the Swedish mutation (<i>App<sup>NL\/NL<\/sup><\/i>, RBRC06342); Swedish and Iberian mutations (<i>App<sup>NL-F\/NL-F<\/sup><\/i>, RBRC06343); and Swedish, Iberian, and Arctic mutations (<i>App<sup>NL-G-F\/NL-G-F<\/sup><\/i>, RBRC06344) [2-4]. The Swedish KM670\/671NL mutation<i> <\/i>increases the total amount of A\u03b2, while the Beyreuther\/Iberian I716F mutation increases the ratio of A\u03b2<sub>42<\/sub> to A\u03b2<sub>40<\/sub>. <i>App<sup>NL-F\/NL-F<\/sup><\/i> mice, which carry the Swedish and Iberian mutations, show A\u03b2 deposition in the cortex and hippocampus at 6 months and memory impairment at 18 months, whereas <i>App<sup>NL\/NL<\/sup><\/i> mice, which carry only the Swedish mutation, are normal. The last group of generated mice, <i>App<sup>NL-G-F\/NL-G-F<\/sup><\/i>, mice carry the Swedish mutation, Iberian mutation, and Arctic E693G mutation, which accelerates A\u03b2 aggregation starting at 2 months and memory impairment at 6 months.<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 5px; background-color: #ffffff; text-align: left; white-space: normal; text-indent: 1em;\" valign=\"top\">\n<p align=\"left\"><i>App<sup>NL-F\/NL-F<\/sup><\/i> and <i>App<sup>NL-G-F\/NL-G-F<\/sup><\/i> mice show typical A\u03b2 pathology, neuroinflammation, and memory impairment, without overexpressing APP or interrupting other mouse genes. These mouse strains will stimulate further research identifying the mechanisms and pathways involved in A\u03b2 amyloidosis.
