ABCA1-Labeled Exosomes in Serum Contain Higher MicroRNA-193b Levels in Alzheimer’s Disease

Figure 3

Levels of exosomal ABCA1 in the serum of WT mice at different points in time after injection of CSF exosomes from WT mice, APP/PS1 AD model mice of different ages, or PBS. After 2 h of injection, the serum exosomal ABCA1 levels of the CSF exosome injection groups were significantly higher than those of the 0-hour groups; the serum exosomal ABCA1 levels of the PBS group were significantly lower than those of the experimental groups.
