Alzheimer's disease (AD) is the most common form of dementia characterized by the presence of amyloid-beta (A beta) plaques and neurofibrillary tangles. The mechanisms leading to AD are not completely understood; however, recent evidence suggests that alterations in Fyn, a Src family kinase, might contribute to AD pathogenesis. A number of studies have demonstrated that Fyn is involved in synaptic plasticity, a cellular mechanism for learning and memory. In addition, Fyn plays a role in the regulation of A beta production and mediates A beta-induced synaptic deficits and neurotoxicity. Fyn also induces tyrosine phosphorylation of tau. Although many studies have implicated a role for Fyn in AD, the precise cellular and molecular mechanisms require further investigation. Novel insights into the role of Fyn in AD may help identify alternative pharmacological approaches for the treatment of AD.
