In preclinical and in-vitro settings, the combined set has been used to examine dual-peptide interactions, signalling behaviour and structural responses within controlled experimental models
Indirect antioxidant effects of NAC were demonstrated in a human ex vivo model of COPD exacerbation induced by lipopolysaccharide (LPS) [69, 70], and confirmed in patients with COPD who showed increased GSH levels in plasma and BAL after NAC treatment [71]
This overload of ROS directly causes lipid peroxidation of the mitochondrial membranes, leading to the persistent opening of the inner membrane permeability transition pores and resulting in a decline in adenosine triphosphate (ATP) synthesis efficiency ( 2+ , resulting in the viability of nucleus pulposus cells recovering from 41% to 78% ( Mitochondrial dysfunction constitutes a core mechanism of energy metabolism imbalance, characterised by decreased activity of mitochondrial complexes I and III and increased electron leakage ( Dysregulation of epigenetic regulation exacerbates oxidative stress, as evidenced by increased methylation of the nuclear factor erythroid 2-related factor 2 (Nrf2) promoter, resulting in reduced Nrf2 expression
