Anti-neuroinflammatory effects of conjugated linoleic acid isomers, c9,t11 and t10,c12, on activated BV-2 microglial cells.

Conjugated linoleic acid (CLA) isomers exhibit anti-inflammatory properties within the central nervous system (CNS). This study investigated the effects of CLA isomers c9,t11 and t10,c12 on fatty acid (FA) and acylethanolamine (NAE) profiles and their association with pro-inflammatory molecule expression in BV-2 microglia cell line, the CNS's resident immune cells responsible for maintaining neuronal activity and immune homeostasis. BV-2 cells were treated with 25 μM of c9,t11-CLA, t10,c12-CLA, or oleic acid (OA) for 24 h, followed by lipopolysaccharide (LPS) stimulation.

Immune responses to oligomeric α-synuclein in Parkinson's disease peripheral blood mononuclear cells.

Parkinson's disease displays clinical heterogeneity, presenting with motor and non-motor symptoms. Heterogeneous phenotypes, named brain-first and body-first, may reflect distinct α-synuclein pathology starting either in the central nervous system or in the periphery. The immune system plays a prominent role in the central and peripheral pathology, with misfolded α-synuclein being placed at the intersection between neurodegeneration and inflammation.

Extract: Inhibition of Skin Aging-Related Enzymes and Nanoformulation.

Plant extracts have long served as important sources of bioactive compounds, and they are currently the focus of extensive research in the development of novel preventive and therapeutic strategies. However, their health benefits are often limited by low bioavailability. Nanoparticle delivery systems can represent a solution to such limitations.

A Liposomal Formulation to Exploit the Bioactive Potential of an Extract from Grape Pomace.

Antioxidant compounds with health benefits can be found in food processing residues, such as grape pomace. In this study, antioxidants were identified and quantified in an extract obtained from Graciano red grape pomace via a green process. The antioxidant activity of the extract was assessed by the DPPH and FRAP tests, and the phenolic content by the Folin-Ciocalteu test.
