DcR3 suppressed Aβ-induced neurotoxicity in primary neuronal cultures. a Schematic of in vitro Aβ and DcR3 treatment conditions. Microglia were stimulated with b, d, e oligomeric and c, f fibrillar Aβ for 72 h with the addition of DcR3 at different time points, and their conditioned media (CM) were collected for treating onto primary neurons. The survival rates of primary neurons after 72 h incubating with different CM were determined by MTT assay. b-c The survival rate of primary neuron treated with CM from microglia exposing to DcR3 at 8 h before stimulating with Aβ. d The survival rate of primary neuron treated with CM from microglia exposing to DcR3 at 0, 24 and 48 h after stimulating with Aβ. e, f The survival rate of primary neuron treated with Aβ-CM in addition with DcR3.
