The identification of α-synuclein overexpression and aggregation as a contributor to METH-induced neurotoxicity may provide a novel therapeutic target for the treatment of the deleterious effect of this drug and drug addiction.The enzyme glutathione transferase M2-2, expressed in human astrocytes, increases its expression in the presence of aminochrome and catalyzes the conjugation of aminochrome, preventing its toxic effects. Secretion of the enzyme glutathione transferase M2-2 from U373MG cells, used as a cellular model for astrocytes, has been reported, and the enzyme is taken up by neuroblastoma SYSH-S7 cells and provide protection against aminochrome. The present study provides evidence that glutathione transferase M2-2 is released in exosomes from U373MG cells, thereby providing a means for intercellular transport of the enzyme. With particular relevance to Parkinson disease and other degenerative conditions, we propose a new mechanism by which astrocytes may protect dopaminergic neurons against the endogenous neurotoxin aminochrome.The vast majority of (BRCA1/2) genetic testing has been conducted in White women, in particular Ashkenazi Jewish women, with limited information available for Black and Hispanic women. Understanding perspectives of those who are underserved is critical to developing interventions to support inclusive approaches to genetic testing. This qualitative study explored knowledge and perceptions of BRCA1/2 genetic testing among diverse women in South Florida. We also explored participants' information needs. Convenience sampling was used to recruit a diverse group of 15 women with a personal or family history of breast cancer. We conducted semi-structured interviews and used
