Anti-Tumoral Activity of a Short Decapeptide Fragment of the Alzheimer’s Abeta Peptide.

The inhibition of angiogenesis is regarded as a promising avenue for cancer treatment. Although some antiangiogenic compounds are in the process of development and testing, these often prove ineffective in vivo, therefore the search for new inhibitors is critical. We have recently identified a ten amino acid fragment of the Alzheimer Abeta peptide that is […]

Impaired orthotopic glioma growth and vascularization in transgenic mouse models of Alzheimer’s disease.

Alzheimer’s disease (AD) is the most common form of dementia among the aging population and is characterized pathologically by the progressive intracerebral accumulation of beta-amyloid (Abeta) peptides and neurofibrillary tangles. The level of proangiogenic growth factors and inflammatory mediators with proangiogenic activity is known to be elevated in AD brains which has led to 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 […]

Depletion of CXCR2 inhibits γ-secretase activity and amyloid-β production in a murine model of Alzheimer’s disease.

Alzheimer’s disease (AD) is a neurodegenerative disorder that leads to progressive cognitive decline. Recent studies from our group and others have suggested that certain G-protein coupled receptors (GPCRs) can influence the processing of the amyloid precursor protein (APP). Earlier, we demonstrated that stimulation of a chemokine receptor, CXCR2, results in enhanced γ-secretase activity and in […]

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 […]

Induction of drug efflux protein expression by venlafaxine but not desvenlafaxine.

Venlafaxine and its metabolite desvenlafaxine are serotonin-norepinephrine reuptake inhibitors currently prescribed for the treatment of depression. Previously, it was reported that venlafaxine is an inducer of MDR1, the gene responsible for P-glycoprotein (P-gp). The present study expanded upon these findings by examining the effect of venlafaxine and desvenlafaxine on the expression of both P-gp and […]

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 […]

Feasibility of Predicting MCI/AD Using Neuropsychological Tests and Serum β-Amyloid.

We examined the usefulness of brief neuropsychological tests and serum Aβ as a predictive test for detecting MCI/AD in older adults. Serum Aβ levels were measured from 208 subjects who were cognitively normal at enrollment and blood draw. Twenty-eight of the subjects subsequently developed MCI (n = 18) or AD (n = 10) over the […]

Flavonoids lower Alzheimer’s Aβ production via an NFκB dependent mechanism.

Alzheimer’s disease (AD) is characterized by the brain accumulation of Aβ peptides and by the presence of neurofibrillary tangles. Aβ is believed to play an important role in AD and it has been shown that certain flavonoids can affect Aβ production. Recently, it was suggested that the Aβ lowering properties of flavonoids are mediated by […]

Mike Mullan Alzheimer Researcher Comments on: Nicotine May Help Combat Memory Loss study by Dr. Newhouse

A recent study at Vanderbilt University Medical Center conducted by Dr. Paul Newhouse and colleagues suggests that Nicotine patches may be very beneficial in individuals with mild cognitive impairment (MCI).

Identification of Plasma Biomarkers of TBI Outcome Using Proteomic Approaches in an APOE Mouse Model.

Abstract The current lack of diagnostic and prognostic biomarkers for traumatic brain injury (TBI) confounds treatment and management of patients and is of increasing concern as the TBI population grows. We have generated plasma proteomic profiles from mice receiving TBI by controlled cortical impact at either 1.3 mm or 1.8 mm depth, comparing these against those of […]

Anatabine lowers Alzheimer’s Aβ production in vitro and in vivo

Brain Aβ accumulation represents a key pathological hallmark in Alzheimer’s disease. In this study, we investigated the impact of anatabine, a minor alkaloid present in plants of the Solanacea family on Aβ production in vitro using a cell line overexpressing the human amyloid precursor protein (APP) and in vivo using a transgenic mouse model of […]

Elevated CSF levels of TACE activity and soluble TNF receptors in subjects with mild cognitive impairment and patients with Alzheimer’s disease.

Expression levels of tumor necrosis factor (TNF) receptors, TNFR1 and TNFR2, are significantly changed in the brains and cerebrospinal fluid (CSF) with Alzheimer’s disease (AD). Moreover, we also found that, in an Alzheimer’s mouse model, genetic deletion of TNF receptor (TNFR1) reduces amyloid plaques and amyloid beta peptides (Aβ) production through β-secretase (BACE1) regulation. TNF-α […]

Genetic deletion of TNF receptor suppresses excitatory synaptic transmission via reducing AMPA receptor synaptic localization in cortical neurons.

The distribution of postsynaptic glutamate receptors has been shown to be regulated by proimmunocytokine tumor necrosis factor α (TNF-α) signaling. The role of TNF-α receptor subtypes in mediating glutamate receptor expression, trafficking, and function still remains unclear. Here, we report that TNF receptor subtypes (TNFR1 and TNFR2) differentially modulate α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptor (AMPAR) clustering […]

Proteomic CNS profile of delayed cognitive impairment in mice exposed to gulf war agents.

Gulf War Illness (GWI) is a chronic multisymptom condition with a central nervous system (CNS) component, for which there is no treatment available. It is now believed that the combined exposure to Gulf War (GW) agents, including pyridostigmine bromide (PB) and pesticides, such as permethrin (PER), was a key contributor to the etiology of GWI.
