Immunostaining of primary neuronal cells from rat brain. Primary neuronal cells were incubated with 2 μM 7 d WT and acetylated Aβ42 peptides for 24 h at 37 °C. Control indicates cells that are untreated and incubated under conditions identical to cells treated with Aβ42 peptides for comparison. The cells were fixed and then stained for immunofluorescence with antibodies for tubulin (green) and tau (red). The images were acquired using Leica DMIL LED at 20× magnification. Scale bar = 50 μm.
