O papel do estresse oxidativo e do exercí­cio fí­sico na doença de Parkinson

Abstract: A Doença de Parkinson (DP) é uma desordem neurodegenerativa que compro­mete os neurônios dopaminérgicos da substância nigra da pars compacta, a qual leva a uma debilitante disfunção motora. O estresse oxidativo tem sido constantemente associado com o desenvolvimento da DP devido às elevadas condições oxidativas que predomina nos neurônios dopaminérgicos. Acredita-se que o exercício físico regular exerça um efeito neuroprotetor sobre a resposta neuroquímica e comportamental. Pretende-se com este estu­do verific… Show more

“…In PD, oxidative stress causes damage to substantia nigra, due to its highly susceptible to contain a high population of dopaminergic neurons that produces significant amounts of ROS. In addition, being post-mitotic, neurons in the brain, once damaged, may be permanently dysfunctional (Tsang & Chung, 2009;Tuon, 2012).…”

“…Although the nature of the neurodegenerative process seen in PD is not known, the involvement of the high oxidative potential of dopamine in H 2 O 2 generation and other ROS has been suggested, as well as the high concentration of iron and its altered homeostasis, and low levels of glutathione (Barbosa et al, 2006;Perfeito et al, 2012;Tsang & Chung, 2009;Tuon, 2012). Another characteristic of PD is the accumulation of iron in the substantia nigra (Perfeito et al, 2012).…”
