As shown in the 2007 Pyo study, copper peptides reduce the cell death enzyme caspase-3 by 42.7% and shift the Bcl-2/Bax survival balance toward cell protection

This process is mediated by glutaredoxins (GLRXs, also known as GRXs), which catalyze both glutathionylation and deglutathionylation, as well as by sulfiredoxins (SRXs) 9,10

Neurofibrillary tangles are pathological, entangled structures in the cytoplasm of neuron cell bodies, dendrites, and axons (Metaxas and Kempf, 2016)

Other investigations relate bacterial LPS, altered bile acids, and tryptophan-derived metabolites to microglial priming, BBB malfunction, and worsening of -synuclein aggregation, giving multi-modal evidence of microbiota-driven neurotoxicity [55]
