Abstract
Acne vulgaris is a type of chronic skin disorder caused by Propionibacterium acnes (P. acnes). Neutrophil extrinsic traps (NETs) play key role in many types of inflammatory skin diseases. Adipose-derived stem cells (ADSCs) was reported modulate immune responses and neutrophil activity. Here, we explored the potential role of ADSCs and the potential mechanism associated with neutrophil extracellular traps (NETs) in relieving acne vulgaris. In the P. acnes-infected ear skin model, histological staining was used to evaluate the inflammatory infiltration and NET formation in control, P. acnes, and P. acnes + ADSCs groups. Besides, western blot was used to detect the expression levels of cit-H3, MPO, and Nrf2 in ear tissue. In vitro, the immunofluorescence staining of MPO and cit-H3, and SYTOX green staining were performed to measure the NET formation. CCK-8 assay, EdU staining, and wound healing assay were used to detect the proliferation and migration abilities of keratinocytes. ELISA assay was utilized to detect the secretion of inflammatory cytokines. In P. acnes-infected ear skin, ADSC treatment significantly attenuated inflammation and NET formation via activating Nrf2 signaling pathway. In vitro, the conditioned medium of ADSCs reduced the formation of P. acne-induced NETs. Besides, ADSCs could inhibit that the NETs efficiently promoted the proliferation, migration, and inflammatory cytokine secretion of keratinocytes. Our study suggested that ADSCs could attenuate P. acne-related inflammation by inhibiting NET formation. This study provides a novel therapeutic perspective of ADSCs in combating acne vulgaris.

Sci Rep 2023; 13:11070. [PMID: 37422509 PMCID: PMC10329718 DOI: 10.1038/s41598-023-38215-5] [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: 12/24/2022] [Accepted: 07/05/2023] [Indexed: 07/10/2023] Open
Abstract
Microbial fuel cells (MFCs) serve two main purposes: clean energy production and wastewater treatment. This study examines the impact of different carbon sources on MFC performance and develops a mathematical model to replicate the polarization curve. The biological reactor employed three types of carbon sources: glucose as a simple feed, microcrystalline cellulose (MCC), and a slurry of the organic component of municipal solid waste (SOMSW) as complex feeds. The MFCs were operated in both open and closed circuit modes. The maximum open circuit voltages achieved were 695 mV for glucose, 550 mV for MCC, and 520 mV for SOMSW as substrates. The influence of the substrate in closed circuit mode was also investigated, resulting in maximum power densities of 172 mW/m2, 55.5 mW/m2, and 47.9 mW/m2 for glucose, MCC, and SOMSW as substrates, respectively. In the second section, a mathematical model was developed to depict the polarization curve while considering voltage losses, namely activation, ohmic, and concentration loss, with an average relative error (ARE) of less than 10%. The mathematical models demonstrated that the activation loss of voltage increased with the complexity of the substrate and reached its peak value when SOMSW was used as the substrate.
