Figure Lengend Snippet: Figure 2. DM mice exhibit synaptic deficits and increased neuroinflammation in the HIP. (A) Repre- sentative WB images showing the expression levels of the presynaptic protein synapsin I (SYN1) and the postsynaptic protein postsynaptic density protein 95 (PSD95) in the HIP of CTL and DM mice. β-actin was used as an internal control. (B) Semi-quantitative analysis of PSD95 and SYN1 expression levels from immunoblot experiments. n = 6. (C) Representative images of Iba1 immunostaining in the HIP of CTL and DM mice. The area within the dashed box is magnified and displayed in the insets. Scale bars: 100 µm (main images) and 20 µm (insets). (D) Quantitative analysis of Iba1-positive microglia in the HIP of CTL and DM mice. n = 5. (E) qPCR analysis of iNOS and Arg1 mRNA levels in the HIP of CTL and DM mice. n = 6. (F) qPCR analysis of IL-6, IL-1β, and TNF-α mRNA levels in the HIP of CTL and DM mice. n = 6. (G) ELISA measuring IL-6, IL-1β, and TNF-α levels in the serum of CTL and DM mice. n = 3. Data are presented as mean ± SEM. Statistical significance was determined using a one-tailed unpaired t-test. * p < 0.05, ** p < 0.01, *** p < 0.001.

Article Snippet: The membranes were blocked and incubated overnight with the following antibodies: PSD95 (SYSN, Toronto, ON, Canada, 124002, 1:1000); SYN1 (SYSN, 106011, 1:1000); Cldn5 (Invitrogen, 35-2500, 1:1000); Ocln (Invitrogen, 71-1500, 1:1000); and MMP9 (Boster, Shanghai, China; PB9669, 1:1000).

Techniques: Expressing, Control, Western Blot, Immunostaining, Enzyme-linked Immunosorbent Assay, One-tailed Test

Figure Lengend Snippet: Figure 6. MSC treatment attenuated DM-induced neuroinflammation and synaptic deficits. (A) Representative immunofluorescence images of Iba1 staining in the HIP of mice from the CTL, MSC, DM, and DM+MSC groups. The dashed box indicates the magnified region shown in the insets. Scale bars: 100 µm (main images) and 20 µm (insets). (B) Quantitative analysis of Iba1+ microglia in the HIP. n = 4. (C) qPCR analysis of iNOS and Arg1 mRNA levels in the HIP of mice from the CTL, MSC, DM, and DM+MSC groups. n = 9. (D) qPCR analysis of mRNA levels of IL-6, IL-1β, and TNF-α in the HIP of mice from the CTL, MSC, DM, and DM+MSC groups. n = 9. (E) ELISA results showing serum levels of IL-6, IL-1β, and TNF-α in CTL, MSC, DM, and DM+MSC mice. n = 4. (F) Representative WB images of PSD95 and SYN1 expression in the HIP. β-actin was used as a loading control. (G) Semi-quantitative analysis of PSD95 and SYN1 protein levels. n = 6. Data are presented as mean ± SEM. Two-way ANOVA followed by Tukey’s post hoc test. ** p < 0.01, *** p < 0.001.
