Human apolipoprotein E (is the main genetic risk factor of Alzheimer’s disease (AD). 112 and 158, leading to alterations in apoE structure and in its affinity toward its ligands and receptors, and thus in its role in neuropathologic conditions.5 However, despite massive research effort in recent years, the exact AD-relevant loss or gain of function resulting from apoE4 expression remains poorly defined.1 It is increasingly acknowledged that AD and cerebrovascular diseases (CVD) share key risk factors such as hypertension, cerebral hypoperfusion, diabetes, hypercholesterolemia, TOK-001 and or tau AD-like neuropathology.13, 14, 15 Finally, BBB-expressed transporters such as the receptor for advanced glycation end products (RAGE) and LRP1 are thought to regulate Atransport in and out of the brain.2,16 Incidentally, an upregulation of RAGE and a downregulation of LRP1 were shown in the AD brain where both changes could contribute to the accumulation and deposition of Adeposition in cerebral parenchyma and microvessels, in an isoform-dependent manner.1 In addition, accumulating evidence suggest that apoE, through its binding to LRP1, mediates the clearance of Aacross the BBB, and that the impairs the morphology and functional properties of the Mouse monoclonal to Rab10 BBB. To verify this, we quantified by brain perfusion the passage of diazepam and glucose through the BBB in mice carrying the different alleles of human (E2, E3, and E4) targeted replacement mice were purchased from Taconic (Hudson, NY, USA) and then reproduced in our laboratory. In these models, the murine gene of C57BL6 mice was replaced by one of three human alleles (E2, E3, or E4).21 Animals were killed at 2, 4, or 12 months of age, or 5 months for the mice used in the human immunoglobulins (hIgG) biodistribution study. All mice had free access to standard laboratory food and water and were kept on a 12-hour light-dark cycle at 223C. All experiments were performed in accordance with the Canadian Council on Animal Care and were approved by the Institutional Committee of the Centre Hospitalier de CHU de Qubec. Brain Perfusion The brain perfusion technique steps the volume of distribution and transport coefficient (Clup) of compounds in the brain after an intracarotid perfusion. Since 100% of the perfusate reaches the BBB, distribution and transport parameters can be readily decided. The cerebrovascular volume is assessed in parallel during the same experiment using a vascular space marker such as [14C]-sucrose (412?mCi/mmol, Moravek Biochemicals, Brea, CA, USA) (0.3?(dpm/(seconds) is the perfusion time. Tissue total radioactivity was corrected for vascular’ contamination with:for 10?minutes at 4C, the supernatant was excluded and the pellet was homogenized in 5?mL of ice-cold DMEM containing 25% bovine serum albumin (BSA) and centrifuged at 1,500?for 45?minutes at 4C. The pellet made up of the microvessels was washed in ice-cold TOK-001 0.1?mol/L PBS and centrifuged again at 12,000?for 20?minutes at 4C. The supernatant was discarded and the pellets TOK-001 were stored at ?80C until processed for western blotting analysis. Protein Extraction The protein extraction was adapted from previous studies.4,8,24 Briefly, the pellet containing the microvessels was weighed and total proteins were extracted by homogenization in eight volumes of lysis buffer (150?mmol/L NaCl, 10?mmol/L NaH2PO4, 1% Triton X-100, 0.5% SDS, and 0.5% deoxycholate, pH 7.4) containing Complete protease inhibitors (Roche, Indianapolis, IN, USA), 10?mg/mL pepstatin A, and phosphatase inhibitors (1?mmol/L sodium pyrophosphate, 50?mmol/L sodium fluoride). The obtained suspension system was sonicated briefly (3 10?secs) and centrifuged.
