Microglia appear activated in the vicinity of amyloid beta (Aβ) plaques, but whether microglia contribute to Aβ propagation into unaffected brain regions remains unknown. Using transplantation of wild-type (WT) neurons, we show that Aβ enters WT grafts, and that this is accompanied by microglia infiltration. Manipulation of microglia function reduced Aβ deposition within grafts. Furthermore, in vivo imaging identified microglia as carriers of Aβ pathology in previously unaffected tissue. Our data thus argue for a hitherto unexplored mechanism of Aβ propagation.

小胶质细胞有助于 Aβ 传播到未受影响的脑组织中

小胶质细胞似乎在β淀粉样蛋白 (Aβ) 斑块附近被激活,但小胶质细胞是否有助于 Aβ 传播到未受影响的大脑区域仍然未知。使用野生型 (WT) 神经元的移植,我们显示 Aβ 进入 WT 移植物,并且伴随着小胶质细胞浸润。小胶质细胞功能的操纵减少了移植物中的 Aβ 沉积。此外,体内成像将小胶质细胞鉴定为以前未受影响的组织中 Aβ 病理学的载体。因此,我们的数据证明了一种迄今为止尚未探索的 Aβ 传播机制。
