doi: 10.1016/j.jbc.2026.111141

Figure Lengend Snippet: Interaction between STRAP and three NOS memebers. A – C , coimmunoprecipitation analysis of STRAP interaction with iNOS ( A ), eNOS ( B ), or nNOS ( C ). HEK293 cells were cotransfected with FLAG-STRAP and iNOS, eNOS, or nNOS expression plasmids. Cell lysates were immunoprecipitated with anti-FLAG antibody or control mouse immunoglobulin G, followed by immunoblotting with anti-iNOS, anti-eNOS, or anti-nNOS antibodies. n = 2. D , detection of S-nitrosylated STRAP (SNO-STRAP) in HEK293 cells overexpressing iNOS, eNOS, or nNOS. Reaction without ascorbate (−Ascorbate) was included as a negative control. n = 3. E , expression levels of iNOS, eNOS, and nNOS in HEK293 cells. eNOS, endothelial nitric oxide synthase; HEK293, human embryonic kidney 293 cell line; iNOS, inducible nitric oxide synthase; NOS, nitric oxide synthase; nNOS, neuronal nitric oxide synthase; SNO, S-nitrosolthiol; STRAP, serine–threonine kinase receptor–associated protein.

Article Snippet: Eluted proteins were separated by SDS-PAGE on 4% to 20% Criterion Precast Midi Protein Gels (Bio-Rad), transferred to PVDF membranes, and probed with the following antibodies: rabbit anti-eNOS (Cell Signaling, 32027S), rabbit anti-nNOS (Cell Signaling, 4231S), rabbit anti-iNOS (Santa Cruz, sc-8310), and rabbit anti-myc (Cell Signaling, 2278S).

Article Title: Blood–brain barrier disruption and neuroinflammation in the hippocampus of a cardiac arrest porcine model: Single-cell RNA sequencing analysis

doi: 10.4103/NRR.NRR-D-24-01269

Figure Lengend Snippet: Enhanced intercellular communication drives neuroinflammatory responses following cardiac arrest. (A) Heatmap illustrating the numbers of inferred interactions between different cell types based on LR pairs. (B) Chord diagram of the top 30 LR pairs between cell types. (C, D) Network diagrams of the changes in the number of intercellular communications between the Sham and ROSC6h groups (C) and the Sham and ROSC24h groups (D). Red represents an increase, and blue represents a decrease, in the number of interactions. (E) Visualization of enhanced LR pairs involved in microglia–neutrophil communication after cardiac arrest in the ROSC6h and ROSC24h groups vs. the Sham group. Each dot represents an LR pair, with its position indicating the group. Dot size corresponds to the P value (larger dots indicate lower P values), while the color represents the interaction probability, with the gradient ranging from purple (low probability) to yellow (high probability). (F) Secretion of resistin into the supernatant of the neutrophil–microglia co-culture system over time. (G) Comparison of resistin secretion, with and without OGD/R and the presence of neutrophils. (H) Immunofluorescence analysis and quantification of iNOS expression in microglia. The left panel shows representative images of iNOS (red), IBA1 (green, microglia marker), and DAPI (blue, nuclei), with merged images in the bottom row. The bar graph shows quantification of relative iNOS fluorescence intensity. Statistical significance determined by one-way analysis of variance followed by Tukey’s post hoc test; **** P < 0.0001. Scale bars: 20 μm. IBA1: Ionized calcium binding adaptor molecule 1; iNOS: inducible nitric oxide synthase; LR: ligand receptor; ns: not significant; OGD/R: oxygen-glucose deprivation/reperfusion; ROSC: return of spontaneous circulation.
