  • Function
    Cooperates with MD-2 and TLR4 to mediate the innate immune response to bacterial lipopolysaccharide (LPS). Acts via MyD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Up-regulates cell surface molecules, including adhesion molecules.
  • Tissue specificity
    Expressed strongly on the surface of monocytes and weakly on the surface of granulocytes; also expressed by most tissue macrophages.
  • Sequence similarities
    Contains 11 LRR (leucine-rich) repeats.
  • Post-translational
    N- and O- glycosylated. O-glycosylated with a core 1 or possibly core 8 glycan.
  • Cellular localization
    Cell membrane.

  • Flow Cytometry analysis of Human monocyte cells labeling CD14 with ab25625 at 1 μg/106 cells (purple). A Goat Anti-Mouse IgG1, Human ads-CY5 was used as the secondary antibody. Grey - Isotype Control, Mouse IgG1-UNLB, followed by Goat Anti-Mouse IgG1, Human ads-CY5.

  • Human peripheral blood cells stained with ab25625 (red line). Human whole blood was processed using a modified protocol based on Chow et al, 2005 (PMID: 16080188). In brief, human whole blood was fixed in 4% formaldehyde (methanol-free) for 10 min at 22°C. Red blood cells were then lyzed by the addition of Triton X-100 (final concentration - 0.1%) for 15 min at 37°C. For experimentation, cells were treated with 50% methanol (-20°C) for 15 min at 4°C. Cells were then incubated with the antibody (ab25625, 0.01μg/1x106 cells) for 30 min at 4°C. The secondary antibody used was Alexa Fluor® 488 goat anti-mouse IgG (H&L) (ab150113) at 1/2000 dilution for 30 min at 4°C. Acquisition of >30,000 total events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

  • Effect of CD14 neutralisation by ab25625 on LPS-induced cytokine release from alveolar macrophages, ATII and TT1 cells.

    Cells were incubated for 1 hr with 10 µg/ml ab25625 prior to addition of 100 ng/ml LPS for 24 hrs. The corresponding IgG isotypes were used as negative controls.
