Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the progressive loss of memory. The neurodegeneration induced by AD has been linked to oxidative damage. However, little is known about the involvement of NADPH oxidase 2 (Nox2), a multisubunit enzyme that catalyzes the reduction of oxygen to produce reactive oxygen species, in the pathogenesis of AD. The main purpose of this...
The Phoneutria nigriventer spider toxin Tx2-6 causes priapism in humans and mice. This toxin produces a delay in Sodium channel inactivation, generalized vascular congestion and death by respiratory failure. NO-Synthase inhibitors seem to abolish toxin-induced priapism. The understanding of the ultimate molecular mechanism involved in toxin-induced priapism may shed light on aspects of erectile function/dysfunction...
Streptozotocin has been widely used to mimic some aspects of Alzheimer’s disease (AD). However, especially in mice, several characteristics involved in the streptozotocin (STZ)-induced AD pathology are not well known. The main purpose of this study was to evaluate temporally the expression of AD-related proteins, such as amyloid-β (Aβ), choline acetyltransferase (ChAT), synapsin, axonal neurofilaments,...
