Glycation modulates glutamatergic signaling and exacerbates Parkinson’s disease...
Chegão, Ana; Guarda, Mariana; Alexandre, Bruno M.; Shvachiy, Liana; Temido Ferreira, Mariana; Marques-Morgado, Inês; Fernandes Gomes, BárbaraAlpha-synuclein (aSyn) is a central player in the pathogenesis of synucleinopathies due to its accumulation in typical protein aggregates in the brain. However, it is still unclear how it contributes to neurodegeneration. Type-2 diabetes mellitus is a risk factor for Parkinson's disease (PD). Interestingly, a common molecular alteration among these disorders is the age-associated increase in protein glycation. ...
Insulin-degrading enzyme: an ally against metabolic and neurodegenerative diseases
Sousa, Luís; Guarda, Mariana; Meneses, Maria João; Macedo, M. Paula; Vicente Miranda, HugoInsulin-degrading enzyme (IDE) function goes far beyond its known proteolytic role as a regulator of insulin levels. IDE has a wide substrate promiscuity, degrading several proteins such as amyloid-β peptide, glucagon, islet amyloid polypeptide (IAPP), and insulin-like growth factors, which have diverse physiological and pathophysiological functions. Importantly, IDE plays other non-proteolytic functions such a...
