Mechanisms of Neuronal Death in Synucleinopathy

alpha-synuclein is a key molecule in the pathogenesis of synucleinopathy including Parkinson's disease and multiple system atrophy. In this mini-review, we mainly focus on recent data obtained from cellular models of synucleinopathy and discuss the possible mechanisms of neurodegeneration. Recent progress suggests that the aggregate formation of alpha-synuclein is cytoprotective and that its pr...

Oxidative Stress Mechanisms during Flower Senescence

Free radicals and other active derivatives of oxygen are inevitable by-products of biological redox reactions and universal under stress situations. Reactive oxygen species inactivate enzymes and damage important cellular processes and subsequently cell components also. Plants and other organisms have evolved a wide range of mechanisms to contend with this problem by promoting the synthesis of ...

Mechanisms of Ischemic Induced Neuronal Death and Ischemic Tolerance

Stroke is the second leading cause of death and the primary cause of disability in humans. The phenomenon of ischemic tolerance perfectly describes the quote: “What does not kill you makes you stronger.’’ Ischemic preor postconditioning is actually the strongest known procedure to prevent or reverse delayed neuronal death. It works specifically in sensitive vulnerable neuronal populations, whic...

Molecular Mechanisms of Phosphorus Metabolism and Transport during Leaf Senescence

Leaf senescence, being the final developmental stage of the leaf, signifies the transition from a mature, photosynthetically active organ to the attenuation of said function and eventual death of the leaf. During senescence, essential nutrients sequestered in the leaf, such as phosphorus (P), are mobilized and transported to sink tissues, particularly expanding leaves and developing seeds. Phos...
