Recombinant Tp0751 interacts with endogenously expressed LamR in brain endothelial cells (bECs). Live hCMEC/d3 monolayers were left untreated (bEC lysate) or coincubated with exogenous recombinant Tp0751 (bEC Lysate + Tp0751). (A) Lysates were incubated with magnetic beads in the absence of antibodies (Lysate + Bead Controls) to control for nonspecific interactions between LamR and the beads. LamR was immunoprecipitated (IP) from lysates using mouse anti-LamR antibody (α-LamR) covalently coupled to magnetic beads, and coimmunoprecipitation of Tp0751 was evaluated by immunoblotting (IB) against Tp0751 (aa 115–237) and LamR. Representative results from three independent experiments are shown. (B) Quantitative immunoblot of LamR (red) and internal control protein GAPDH (green) from untreated or Tp0751-treated bEC lysates (C) LamR band intensity normalized to GAPDH band intensity from untreated or Tp0751-treated bEC lysates. Results representative of two independent experiments.
