Article Title: Inhibition of peripheral VEGF signaling rapidly reduces leucocyte obstructions in brain capillaries and increases cortical blood flow in an Alzheimer’s disease mouse model

doi: 10.1101/2021.03.05.433976

Figure Lengend Snippet: ELISA measurements of VEGF1R receptor ( A ), VEGF2R receptor ( B ) from brain lysates, and soluble VEGF1R receptor ( C ), and soluble VEGF2R receptor ( D ) from plasma samples after 1 week of anti-VEGF-A treatment or saline injections in APP/PS1 and WT mice (n=3 mice per group). Kruskal-Wallis test with multiple comparison correction to compare across groups. In all graphs each point represents the ELISA measurement from one mouse, red horizontal line represents the median; * indicates p = 0.05.

Article Snippet: After the measuring the concentrations ELISAs were performed following the manufacture’s protocol (VEGF1R (MVR100) and VEGF2R (MVR200B), R&D Systems).

Article Title: Cross-family Signaling: PDGF Mediates VEGFR Activation and Endothelial Function

doi: 10.1101/2025.02.27.640684

Figure Lengend Snippet: HBMECs were starved with low-serum medium for 6 hours and stimulated with growth factors at the indicated concentrations for 30 min (VEGFR1) or 10 min (VEGFR2). The receptor activation was picked up either by ELISA detecting the pan-tyrosine phosphorylation of VEGFR1 (A–C) or VEGFR2 (D) , or by immunoblotting and probed with primary antibody targeting VEGFR2 phosphorylation at tyrosine site 1175 (E) .

Article Snippet: After being briefly vortexed and centrifuged at 12,000× g for 10 min at 4 °, the cell lysates went through the protocol of Human Phospho-VEGFR1/Flt-1 DuoSet IC ELISA kit (R&D Systems, DYC4170), Human Phospho-VEGFR2/KDR DuoSet IC ELISA kit (R&D Systems, DYC1766), or Human Phospho-PDGFRβ DuoSet IC ELISA kit (R&D Systems, DYC1767) to assess the phosphorylation levels of VEGFR1, VEGFR2, or PDGFRβ, respectively.

Article Title: Cross-family Signaling: PDGF Mediates VEGFR Activation and Endothelial Function

doi: 10.1101/2025.02.27.640684

Figure Lengend Snippet: (A– G) HDMEC ( PDGFRA −/− and PDGFRB −/− ) were starved with low-serum medium for 6 hours and stimulated with growth factors at the indicated concentrations for 30 min (VEGFR1) or 10 min (VEGFR2). (A–C) The fold changes of VEGFR1 phosphorylation induced were assessed via ELISA. (D–G) The fold changes of VEGFR1 phosphorylation induced were assessed via immunoblotting. (H) The fold changes of PDGFRβ phosphorylation in HDFs induced by 30-min VEGF-A or PDGF-BB treatment were measured via ELISA.
