Anti-melanogenic and Antioxidant Activities of Lactiplantibacillus plantarum Strains in Skin Cells via the CREB/MITF and Nrf2/HO-1 Pathways.

This study evaluated the probiotic characteristics of Lactiplantibacillus plantarum strains, revealing strong acid and bile salt tolerance and significant adhesion to HT-29 cells. In addition, the anti-melanogenic and antioxidant properties of their cell-free supernatants (CFS) were investigated in vitro. Melanogenesis assays were performed in α-melanocyte-stimulating hormone (α-MSH)-stimulated B16F10 melanoma cells, while antioxidant activity was evaluated in HO-stimulated HaCaT keratinocytes.

Probiotic Pediococcus acidilactici Strains Exert Anti-inflammatory Effects by Regulating Intracellular Signaling Pathways in LPS-Induced RAW 264.7 Cells.

This study investigated the anti-inflammatory effects of Pediococcus acidilactici strains isolated from fermented vegetables on lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. In addition, the probiotic characteristics and safety were evaluated.

Heat-Treated Paraprobiotic KU15041 and KU15003 Show an Antioxidant and Immunostimulatory Effect.

The lactic acid bacteria, including and , have been widely studied for their preventive and therapeutic effects. In this study, the underlying mechanism of action for the antioxidant and immunostimulatory effects of two strains of heat-treated paraprobiotics was examined. Heat-treated KU15041 and KU15003 showed higher radical scavenging activity in both the 2-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and 2,2-diphenyl-1-picryl-hydrazyl (DPPH) assays than the commercial probiotic strain LGG.

Anti-inflammatory activities of KU15147 in RAW 264.7 cells stimulated with lipopolysaccharide on attenuating NF-κB, AP-1, and MAPK signaling pathways.

Unlabelled: Probiotics confer many beneficial effects on several illnesses, ranging from microbial diarrhea to inflammatory diseases. This study was conducted on whether KU15147 obtained from kimchi has anti-inflammatory effects in RAW 264.7 cells stimulated with lipopolysaccharide (LPS) and antioxidant potential.
