Exogenous FGF1 alleviates diabetes-induced Aβ1–42 deposition and synaptic dysfunction. a The immunohistochemical staining of Aβ1–42 and immunofluorescence staining of p-Tau in the CA1 of hippocampus (Scale bar = 15 μm); b Western blotting and quantitative analysis of synaptic function related protein expressions (PSD95, synaptophysin and synapsin-1) in the hippocampus; c Co-immunofluorescence staining of PSD95 and synaptophysin in the CA1 of hippocampus (Scale bar = 15 μm). *p < 0.05, **p < 0.01 vs. the other two groups, n = 3
