Abstract
Alzheimer's disease (AD) is a chronic neurodegenerative disorder marked by gradual cognitive deterioration and distinct neuropathological characteristics. The abnormal accumulation of amyloid-β (Aβ) and neurofibrillary tangles (NFTs) are the hallmarks of AD. In fact, synaptic loss and damage occur earlier than amyloid plaques and NFTs in the progression of AD and are most closely associated with the cognitive deficits exhibited by AD patients. In this review, we discuss the expression level, localization, posttranslational modification and interaction proteins of PSD-95, as well as their roles in synaptic plastisity. We also review the mechanisms through which PSD-95 contributes to synaptic dysfunction in AD. Moreover, the potential of PSD-95 as an early biomarker for AD is also discussed, along with the therapeutic approaches that target PSD-95 for patients afflicted with the disease. The objective of this review is to offer comprehensive insights into the early pathogenesis of Alzheimer's disease and to aid in the development of novel diagnostic and treatment methodologies grounded in this understanding.
期刊介绍:
Biochemical Pharmacology publishes original research findings, Commentaries and review articles related to the elucidation of cellular and tissue function(s) at the biochemical and molecular levels, the modification of cellular phenotype(s) by genetic, transcriptional/translational or drug/compound-induced modifications, as well as the pharmacodynamics and pharmacokinetics of xenobiotics and drugs, the latter including both small molecules and biologics.
The journal''s target audience includes scientists engaged in the identification and study of the mechanisms of action of xenobiotics, biologics and drugs and in the drug discovery and development process.
All areas of cellular biology and cellular, tissue/organ and whole animal pharmacology fall within the scope of the journal. Drug classes covered include anti-infectives, anti-inflammatory agents, chemotherapeutics, cardiovascular, endocrinological, immunological, metabolic, neurological and psychiatric drugs, as well as research on drug metabolism and kinetics. While medicinal chemistry is a topic of complimentary interest, manuscripts in this area must contain sufficient biological data to characterize pharmacologically the compounds reported. Submissions describing work focused predominately on chemical synthesis and molecular modeling will not be considered for review.
While particular emphasis is placed on reporting the results of molecular and biochemical studies, research involving the use of tissue and animal models of human pathophysiology and toxicology is of interest to the extent that it helps define drug mechanisms of action, safety and efficacy.
