General description

Solutions should be freshly prepared and protected from exposure to light.

Application

6-Hydroxydopamine hydrobromide has been used:
  • to induce Parkinson′s disease (PD) in mouse models to study the effects of tubastatin A (TBA) on nucleotide-binding oligomerization domain and leucine-rich repeat pyrin 3 domain (NLRP3) activation and cell injury in SH-SY5Y cells
  • to induce pharmacological ablation of the sympathetic nerves to study the effect of hepatic sympathetic nerve activity (SNA) on hepatic steatosis during diet-induced obesity in mice
  • to induce oxidative stress in mesencephalic cells to study its effect on p75NTR signaling in neuronal cells of the ventral mesencephalon

Biochem/physiol Actions

6-Hydroxydopamine hydrobromide (6-OHDA) is a neurotoxin that elicits oxidative damage and destroys catecholaminergic or sympathetic terminals. It is commonly used to induce Parkinson′s disease in the experimental model. 6-OHDA exerts cytotoxicity by generating reactive oxygen species, initiating cellular stress and cell death.

6-Hydroxydopamine (6-OHDA) is a neurotoxin that generates an experimental model of Parkinson's disease in rodents and is commonly employed to induce a lesion in dopaminergic pathways. The characterization of those molecular mechanisms linked to 6-OHDA-induced early toxicity is needed to

Physical exercise is known to produce beneficial effects to the nervous system. In most cases, brain-derived neurotrophic factor (BDNF) is involved in such effects. However, little is known on the role of BDNF in exercise-related effects on Parkinson's disease (PD).
