(B–D) Statistics of GluN1 (B) , GluN2A (C) and PSD-95 (D) protein levels in the hippocampus of T2D (Goto Kakizaki-vehicle) and control (Wistar-vehicle). (E) Western blot analysis of selected glutamate receptors and postsynaptic density protein 95 (PSD-95) in the hippocampus of Goto Kakizaki-vehicle and Goto Kakizaki-dorzagliatin rats. (F–H) Statistics of GluN1 (F) , GluN2A (G) and PSD-95 (H) protein levels in the hippocampus of Goto Kakizaki-vehicle group and Goto Kakizaki-dorzagliatin group. Data are expressed as mean ± SEM.

Article Title: Disrupted maternal care alters neural-microglia interactions in the primate paralaminar (PL) nucleus of the amygdala

doi: 10.64898/2026.01.06.697965

Figure Lengend Snippet: A. Low-magnification (4x) overview of the paralaminar nucleus (PL) ventral to the basal amygdala, highlighting the location of the analysis identified by (DCX+) neurons. Scale bar: 300 µm. B. High-magnification (60x) photomicrograph of the PL neuropil depicting SYN1(green) and PSD95 (red) immunoreactivity. Scale bar: 10 µm. C. Spot rendering of SYN1 (green) and PSD95 (red) puncta at low power. Scale bar: 10 μm. D. Putative synaptic contacts (SYN1 and PSD95 overlap, greater than 50%) in yellow, double arrow. Single arrows show SYN1 and PSD95 puncta pairs that are non-overlapping. Scale bar = 2 μm. E. Mean number of SYN1-single labeled puncta across groups. F. mean number of PSD95-single labeled puncta across groups. G. Mean number of putative synaptic contacts (SYN1-PSD95 colocalized) across groups. H. Percentage of SYN1 contacts per total available SYN1+ puncta. I. Percentage of PSD95 contacts per total available PSD95+ puncta. Statistical significance: *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
