چکیده

Proteolytic processing of the amyloid-beta precursor protein (APP) generates the Abeta amyloid peptide of Alzheimer's disease. The biological function of APP itself remains, however, unclear. In the current review, we study in detail the different subdomains of APP and try to assign functional significance to particular structures identified in the protein.

P 102: The Study of Some Factors Which Effect on Beta-Amyloid Signaling in Neuroinflammation

Neurological inflammatory diseases are developing rapidly. Different factors involved in the pathogenesis of these diseases. In this article, we discuss some of the mechanisms are dealt with. An aberrant procedure of beta-amyloid precursor protein (BAPP) to form neurotoxic beta-amyloid peptides and an accumulated insoluble polymer of beta –amyloid (BA) that forms the senile plaque. The ab...

Proteolytic processing and cell biological functions of the amyloid precursor protein.

Recent research has identified some key players involved in the proteolytic processing of amyloid precursor protein (APP) to amyloid beta-peptide, the principal component of the amyloid plaques in Alzheimer patients. Interesting parallels exists with the proteolysis of other proteins involved in cell differentiation, cholesterol homeostasis and stress responses. Since the cytoplasmic domain of ...

Minocycline blocks c-terminal fragments of amyloid precursor protein-induced neurotoxicity by inhibition of cytochrome c release and caspase-12 activation

Minocycline is a second-generation tetracycline that effectively crosses the blood-brain barrier. It has remarkable neuroprotective qualities in models of cerebral ischaemia, traumatic brain injury, Huntington’s and Parkinson’s diseases. However, there is no evidence about neuroprotective effects of minocycline on AD. Alzheimer’s disease (AD) is a neurodegenerative disorder characterized neurop...

Amyloid precursor protein trafficking, processing, and function.

Intracellular trafficking and proteolytic processing of amyloid precursor protein (APP) have been the focus of numerous investigations over the past two decades. APP is the precursor to the amyloid beta-protein (Abeta), the 38-43-amino acid residue peptide that is at the heart of the amyloid cascade hypothesis of Alzheimer disease (AD). Tremendous progress has been made since the initial identi...
