Overlay histogram showing HL60 cells stained with ab81719 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab81719, 1μg/1x10⁶ cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2μg/1x10⁶ cells) used under the same conditions. Unlabelled sample (blue line). Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in HL60 cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Supplementary information

PLVAP also known as PV-1 is a transmembrane protein that plays a significant role in organizing the stomatal and fenestral diaphragms of endothelial cells. It weighs approximately 60 kDa. This protein is mainly expressed in fenestrated capillaries and sinusoidal endothelium where it forms diaphragms and contributes to the permeability and ultrastructure of capillary beds. PLVAP's role in endothelial cells highlights its importance in maintaining vascular permeability and cellular structures.

Biological function summary

The functions of PLVAP are significant in maintaining an organized structure within endothelial cells. It forms part of the complex structure that comprises the diaphragms of endothelial fenestrae transendothelial channels and caveolae. These structures are necessary for regulating fluid exchange and molecular transport between blood and tissue. The presence of PLVAP at these sites signals its role in modulating vascular barrier functions essential for efficient blood-tissue communication.

Pathways

Researchers have identified PLVAP's involvement in important vascular and endothelial pathways. It plays a critical part in the VEGF signaling pathway which regulates vascular permeability and endothelial cell behavior. PLVAP is closely associated with other proteins like VE-cadherin and claudin-5 that ensure cohesion and permeability in endothelial cells. In pathways regulating vascular permeability PLVAP's presence helps mediate fluid exchange and maintain tissue homeostasis.

PLVAP associates with conditions involving vascular dysregulation. Hypo- or hyper-expression of PLVAP can relate to the pathogenesis of cancer and inflammatory diseases. In cancer changes in PLVAP expression might contribute to altered tumor vasculature and metastasis often in association with proteins like VEGF and VEGFR-2. Furthermore inflammatory diseases such as atherosclerosis see changes in the protein expression levels that might disrupt vascular integrity linking them with proteins involved in inflammatory responses like ICAM-1 and VCAM-1.

Target data

Endothelial cell-specific membrane protein involved in the formation of the diaphragms that bridge endothelial fenestrae. It is also required for the formation of stomata of caveolae and transendothelial channels. Functions in microvascular permeability, endothelial fenestrae contributing to the passage of water and solutes and regulating transcellular versus paracellular flow in different organs. Plays a specific role in embryonic development.
