Paris Pizarro, Irmgard; Muñoz, Patricia; Huenchuguala, Sandro; Couve, Eduardo; Sanders, Laurie H.; Greenamyre, John Timothy; Caviedes, Pablo; Segura Aguilar, Juan (2011)Aminochrome, the precursor of neuromelanin, has been proposed to be involved in the neurodegeneration neuromelanincontaining dopaminergic neurons in Parkinson's disease. We aimed to study the mechanism of aminochrome-dependent ...

Huenchuguala, Sandro; Muñoz, Patricia; Graumann, Rebecca; Paris Pizarro, Irmgard; Segura Aguilar, Juan (Elsevier, 2016)Astrocytes are exposed to aminochrome via the oxidation of dopamine that is taken up from the synaptic cleft after its release from dopaminergic neurons. Glutathione transferase M2-2 (GSTM2) has been shown to protect ...

Huenchuguala, Sandro; Muñoz, Patricia; Zavala, Patricio; Villa, Mónica; Urriola Cuevas, Carlos; Ahumada, Ulises; Graumann, Rebecca; Nore, Beston F.; Couve, Eduardo; Mannervik, Bengt; Paris Pizarro, Irmgard; Segura Aguilar, Juan (Taylor and Francis Inc., 2014)U373MG cells constitutively express glutathione S-transferase mu 2 (GSTM2) and exhibit 3H-dopamine uptake, which is inhibited by 2 μM of nomifensine and 15 μM of estradiol. We generated a stable cell line (U373MGsiGST6) ...

Novel Alpha-Synuclein Oligomers Formed with the Aminochrome-Glutathione Conjugate Are Not Neurotoxic Huenchuguala, Sandro; Sjödin, Birgitta; Mannervik, Bengt; Segura-Aguilar, Juan (Springer New York LLC, 2019)© 2018, Springer Science+Business Media, LLC, part of Springer Nature.Aminochrome induces neurotoxic alpha-synuclein oligomer formation relevant to the etiology of Parkinson’s disease. Oxidative stress produces aminochrome ...
