An in situ mouse brain perfusion model predictive of passive and carrier-mediated transport across the blood-brain barrier (BBB) was developed and applied to mdr1a P-glycoprotein (Pgp)-deficient mice [mdr1a(-/-)]. Cerebral flow was estimated from diazepam uptake. Physical integrity of the BBB was assessed with sucrose/inulin spaces; functional integrity was(More)
P-glycoprotein (P-gp) and organic anion transporting polypeptides (Oatp) are expressed at the blood-brain barrier (BBB). There is little functional evidence for Oatp-mediated transport at the BBB. The peptidic delta opioid-receptor agonist [D-penicillamine(2,5)]-enkephalin (DPDPE) is a substrate of mdr1a P-gp and Oatp2. The present study evaluated the(More)
We previously reported that CD21(+) B cells purified from bovine blood do not respond to CpG-ODN stimulation unless either CD14(+) monocytes or B-cell Activating Factor (BAFF), a cytokine produced by activated monocytes, are present. In this report, we present evidence that CD14(+) monocytes are critical for CpG-specific lymphocyte proliferation within the(More)
