Study 1

The promise of N‐acetylcysteine in the treatment of obsessive‐compulsive disorder

Journal:
CNS Neurosci Ther. 2024 Feb 22;30(2):e14653. | PMID: 38385640
Summary:
This letter to the Journal is intended to raise awareness within the scientific community about the potential use of N‐acetylcysteine (NAC) as an alternative treatment for obsessive‐compulsive disorder (OCD), primarily targeting glutamatergic system dysfunctions and modulating inflammatory cytokines.

Study 2

The antioxidant N-acetylcysteine promotes immune response and inhibits epithelial-mesenchymal transition to alleviate pulmonary fibrosis in chronic obstructive pulmonary disease by suppressing the VWF/p38 MAPK axis

Journal:
Molecular Medicine, Volume 27, article number 97, (2021)
Summary:
Collectively, NAC could ameliorate COPD-induced pulmonary fibrosis by promoting immune response and inhibiting EMT process via the VWF/p38 MAPK axis, therefore providing us with a potential therapeutic target for treating COPD.

N-Acetylcysteine Improves Liver Function in Patients with Non-Alcoholic Fatty Liver Disease

Journal:
Hepat Mon. 2010 Mar 1;10(1):12–16. | PMID: 22308119
Summary:
The current study described the effectiveness of a three-month consumption of NAC in patients with NAFLD, which resulted in a decrease in the level of ALT and in the size of the spleen, compared to those patients taking vitamin C. To our knowledge, few studies have been carried out to examine the implication of NAC on liver function in patients with NAFLD, and in particular on liver hemodynamics.

The role for N-acetylcysteine in the management of COPD

Journal:
Int J Chron Obstruct Pulmon Dis. 2006 Jun;1(2):99–106 | PMID: 18046886
Summary:
Oxidative stress is considered to be an important part of the inflammatory response to both environmental and internal signals. Transcription factors like NF-kb and AP-1 are activated by oxidative stress and in turn amplify the inflammatory response to noxious stimuli. In this way, both oxidative stress and inflammation are involved in the complex pathophysiology of COPD, both in terms of pathogenesis and progression of the disease.
