β-amyloid and Oxidative Stress: Perspectives in Drug Development

Current Pharmaceutical Design
Giuseppe CarusoSara Merlo


Alzheimer's Disease (AD) is a slow-developing neurodegenerative disorder in which the main pathogenic role has been assigned to β-amyloid protein (Aβ) that accumulates in extracellular plaques. The mechanism of action of Aβ has been deeply analyzed and several membrane structures have been identified as potential mediators of its effect. The ability of Aβ to modify neuronal activity, receptor expression, signaling pathways, mitochondrial function, and involvement of glial cells have been analyzed. In addition, extensive literature deals with the involvement of oxidative stress in Aβ effects. Herein we focus more specifically on the reciprocal regulation of Aβ, that causes oxidative stress, that favors Aβ aggregation and toxicity and negatively affects the peptide clearance. Analysis of this strict interaction may offer novel opportunities for therapeutic intervention. Both common and new molecules endowed with antioxidant properties deserve attention in this regard.

Astrocytes and Neurodegeneration

Astrocytes are important for the health and function of the central nervous system. When these cells stop functioning properly, either through gain of function or loss of homeostatic controls, neurodegenerative diseases can occur. Here is the latest research on astrocytes and neurodegeneration.


Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.

Astrocytes & Huntington’s Disease

Astrocytes are abundant within the central nervous system and their dysfunction has been thought to be an important contributor to some neurodegenerative diseases, in particular Huntington’s disease. Damage to these cells may make neurons more susceptible to degeneration. Here is the latest research on astrocytes and Huntington’s disease.

Alzheimer's Disease: Abeta

Alzheimer's disease (AD) is a chronic neurodegenerative disease associated with accumulation of amyloid plaques, which are comprised of amyloid beta. Here is the latest research in this field.
