A New Study Shows Small-molecule Drug through Blood-Brain Barrier

Mayo clinic researchers demonstrated within a mouse model that a synthetic peptide carrier works to deliver brain cancer chemotherapy drugs, as well as neurological medications. Neuroscientist Gobinda Sarkar, Ph.D, of the Mayo Clinic and corresponding author of the study discussed that they were able to transport eight different molecules, and much less disruptively through the […]

Characterization and use of human brain microvascular endothelial cells to examine β-amyloid exchange in the blood-brain barrier. Bachmeier C, Mullan M, Paris D.

Alzheimer’s disease (AD) is characterized by excessive cerebrovascular deposition of the β-amyloid peptide (Aβ). The investigation of Aβ transport across the blood-brain barrier (BBB) has been hindered by inherent limitations in the cellular systems currently used to model the BBB, such as insufficient barrier properties and poor reproducibility. In addition, many of the existing models […]

Selective antihypertensive dihydropyridines lower Aβ accumulation by targeting both the production and the clearance of Aβ across the blood-brain barrier.

Several large population-based or clinical trial studies have suggested that certain dihydropyridine (DHP) L-type calcium channel blockers (CCBs) used for the treatment of hypertension may confer protection against the development of Alzheimer disease (AD). However, other studies with drugs of the same class have shown no beneficial clinical effects. To determine whether certain DHPs are […]

Selective dihydropyiridine compounds facilitate the clearance of β-amyloid across the blood-brain barrier.

Increasing evidence suggests that the soluble form of the β-amyloid peptide (Aβ) plays a critical role in the pathogenesis of Alzheimer’s disease. Previously, we reported that treatment with certain antihypertensive dihydropyridine (DHP) compounds can mitigate Aβ production in whole cells and reduce brain Aβ burden in a mouse model of Alzheimer’s disease. As Aβ clearance […]

Alzheimer’s beta-amyloid peptide blocks vascular endothelial growth factor mediated signaling via direct interaction with VEGFR-2

By Patel NS, Mathura VS, Bachmeier C, Beaulieu-Abdelahad D, Laporte V, Weeks O, Mullan M, Paris D. Published in J Neurochem. 2010 Jan;112(1):66-76. Roskamp Institute, Sarasota, Florida, USA. npatel@scripps.edu Abstract Beta-amyloid peptides (Abeta) are the major constituents of senile plaques and cerebrovascular deposits in the brains of Alzheimer’s disease patients. We have shown previously that […]

Roskamp Institute-LECOM collaboration

Dr. Corbin Bachmeier of the Roskamp Institute is currently investigating the drug efflux transport interactions of various antidepressants in collaboration with Dr. Gary Levin of the Lake Erie College of Osteopathic Medicine (LECOM) in Bradenton, FL.  Dr. Bachmeier and Dr. Levin are co-investigators of a grant, provided by Wyeth Pharmaceuticals, which examines the interactions of […]
