Abstract
Parkinson's disease (PD) is a progressive neurodegenerative disease characterized by resting tremor, bradykinesia, rigidity, and postural instability that also includes non-motor symptoms such as mood dysregulation. Dopamine (DA) is the primary neurotransmitter involved in this disease, but cholinergic imbalance has also been implicated. Current intervention in PD is focused on replenishing central DA, which provides remarkable temporary symptomatic relief but does not address neuronal loss and the progression of the disease. It has been well established that neuronal nicotinic cholinergic receptors (nAChRs) can regulate DA release and that nicotine itself may have neuroprotective effects. Recent studies identified nAChRs in nonneuronal cell types, including glial cells, where they may regulate inflammatory responses. Given the crucial role of neuroinflammation in dopaminergic degeneration and the involvement of microglia and astrocytes in this response, glial nAChRs may provide a novel therapeutic target in the prevention and/or treatment of PD. In this review, following a brief discussion of PD, we focus on the role of glial cells and, specifically, their nAChRs in PD pathology and/or treatment.

Skok M. The role of α7 nicotinic acetylcholine receptors in post-acute sequelae of covid-19. Int J Biochem Cell Biol 2024; 168:106519. [PMID: 38218363 DOI: 10.1016/j.biocel.2024.106519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 12/25/2023] [Accepted: 01/08/2024] [Indexed: 01/15/2024]
Abstract
Post-Acute Sequelae of COVID-19 or Long COVID becomes evident some weeks to months following acute COVID-19. Symptoms include cognitive impairment and varying degrees of memory loss with no definitive etiologies or efficacious therapies forthcoming even after four years of the SARS-Cov2 pandemic virus. The aim of this review is to demonstrate the important role of α7 nicotinic acetylcholine receptors in both acute COVID-19 and Long COVID. Evidence presented implicates immune mechanisms stimulated by SARS-Cov-2 S-protein fragment 674-685 that possesses homology with α7-specific ligands. Cognitive dysfunctions observed in Long COVID patients may be derived from anti-idiotypic α7-specific antibodies stimulated by (674-685)-specific antibodies. Therapeutic interventions capable of neutralizing these antibodies and restoring full functions of α7 nicotinic acetylcholine receptors appear to be of paramount importance in post-acute sequelae of COVID-19.

Neoplasia 2023; 46:100950. [PMID: 37976568 PMCID: PMC10685044 DOI: 10.1016/j.neo.2023.100950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 11/10/2023] [Accepted: 11/10/2023] [Indexed: 11/19/2023]
Abstract
OBJECTIVE This study aimed to investigate the causal relationship between mitochondrial biological function and lung cancer, including its subtypes, via MR. METHODS SNPs significantly associated with lung cancer and its subtypes were employed as instrumental variables. MR-Egger regression, simple mode, weighted mode, simple median, and weighted median, were utilized to determine the causal relationship between the exposure factor and the occurrence of lung cancer and its subtypes. RESULTS NADH dehydrogenase (ubiquinone) flavoprotein 2 and transmembrane protein 70 were found to have a causal relationship with lung adenocarcinoma, acting as protective factors. The causal relationship between mitochondrial import inner membrane translocase subunit and NADH dehydrogenase (ubiquinone) iron-sulfur protein 4 and small-cell lung cancer was established as a risk factor. NADH dehydrogenase (ubiquinone) 1 beta subcomplex subunit 8 exhibited a causal relationship with small-cell lung cancer, acting as a protective factor. Furthermore, NAD-dependent protein deacylase sirtuin-5 was causally linked to lung squamous cell carcinoma, serving as a protective factor. A funnel plot demonstrated the symmetrical distribution of the SNPs. Thew pleiotroy test (P > 0.05) and "leave-one-out" test validated the relative stability of the results. CONCLUSION This study established a causal relationship between mitochondrial biological function and lung cancer, including its subtypes.
