Megjegyzések:	Investigating the molecular composition of small extracellular vesicles (sEVs) for tumor diagnostic purposes is becoming increasingly popular, especially for diseases for which diagnosis is challenging, such as central nervous system (CNS) malignancies. Thorough examination of the molecular content of sEVs by Raman spectroscopy is a promising but hitherto barely explored approach for these tumor types. We attempt to reveal the potential role of serum-derived sEVs in diagnosing CNS tumors through Raman spectroscopic analyses using a relevant number of clinical samples. A total of 138 serum samples were obtained from four patient groups (glioblastoma multiforme, non-small-cell lung cancer brain metastasis, meningioma and lumbar disc herniation as control). After isolation, characterization and Raman spectroscopic assessment of sEVs, the Principal Component Analysis?Support Vector Machine (PCA?SVM) algorithm was performed on the Raman spectra for pairwise classifications. Classification accuracy (CA), sensitivity, specificity and the Area Under the Curve (AUC) value derived from Receiver Operating Characteristic (ROC) analyses were used to evaluate the performance of classification. The groups compared were distinguishable with 82.9?92.5% CA, 80?95% sensitivity and 80?90% specificity. AUC scores in the range of 0.82?0.9 suggest excellent and outstanding classification performance. Our results support that Raman spectroscopic analysis of sEV-enriched isolates from serum is a promising method that could be further developed in order to be applicable in the diagnosis of CNS tumors.

Megjegyzések:	Propionibacterium acnes is an important member of theskin microbiome. The bacterium can initiate signallingevents and changes in cellular properties in keratinocytes.The aim of this study was to analyse the effect ofthe bacterium on an immortalized human keratinocytecell line. The results show that various P. acnes strainsaffect the cell-growth properties of these cells differentially,inducing cytotoxicity in a strain-specific and dosedependentmanner. We propose that bacterially secretedpropionic acid may contribute to the cytotoxic effect.This acid has a role in maintaining skin pH and exhibitsantimicrobial properties, but may also have deleteriouseffects when the local concentration rises due to excessivebacterial growth and metabolism. These results, togetherwith available data from the literature, may provide insightinto the dual role of P. acnes in healthy skin andduring pathogenic conditions, as well as the key moleculesinvolved in these functions. Key words: immortalizedkeratinocyte cell line (HPV-KER); Propionibacterium acnes;acne vulgaris; short-chain fatty acid; propionic acid.
