AB  - Background: Although still considered a safer alternative to classical cigarettes, growing body of work points toharmful effects of electronic cigarettes (e-cigarettes) affecting a range of cellular processes. The biological effect ofe-cigarettes needs to be investigated in more detail considering their widespread use.Methods: In this study, we treated V79 lung fibroblasts with sub-cytotoxic concentration of e-cigarette liquids, withand without nicotine. Mutagenicity was evaluated by HPRT assay, genotoxicity by comet assay and the effect on cel-lular communication by metabolic cooperation assay. Additionally, comprehensive proteome analysis was performedvia high resolution, parallel accumulation serial fragmentation-PASEF mass spectrometry.Results: E-cigarette liquid concentration used in this study showed no mutagenic or genotoxic effect, however itnegatively impacted metabolic cooperation between V79 cells. Both e-cigarette liquids induced significant depletionin total number of proteins and impairment of mitochondrial function in treated cells. The focal adhesion proteinswere upregulated, which is in accordance with the results of metabolic cooperation assay. Increased presence of post-translational modifications (PTMs), including carbonylation and direct oxidative modifications, was observed. Data areavailable via ProteomeXchange with identifier PXD032071.Conclusions: Our study revealed impairment of metabolic cooperation as well as significant proteome and PTMsalterations in V79 cells treated with e-cigarette liquid warranting future studies on e-cigarettes health impact.

AB  - The COVID-19 pandemic caused by the SARS-CoV2 virus poses a global health threat with over 5 million deaths recorded. There is little understanding regarding SARS-CoV2 pathogenesis in the human airways and disease severity increases with age. Neutrophils are white blood cells found in large numbers in the airways of the lungs in severe COVID-19 patients. It is not known whether this influx of neutrophils into the airway has a protective or detrimental effect. We aim to understand the role of neutrophils during COVID-19 pathology, using an experimental infection model of the airway epithelium from the eldelry and children. To do this, we collect nasal airway cells from healthy elderly and children and grow them at air-liquid interface. Once differentiation and ciliation of these cells is reached, we infect the cells with SARS-CoV2 virus and allow neutrophils to migrate from the basolateral (blood) to the apical (air) side of the epithelium, similar to a physiological airway. Using flow cytometric analyses, we measure the expression of activation markers and the number of neutrophils that migrate across the epithelium of different ages in response to SARS-CoV2 infection. Preliminary work shows less viable neutrophils recovered from the elderly epithelium, more activated neutrophils when migrating through the elderly epithelium, as well as increased numbers of neutrophils remaining on the basolateral (blood) side of the elderly epithelium. These findings point to an inflammatory neutrophil phenotype influenced by the damaged elderly epithelium and supports the hypothesis that neutrophils are responsible for the severity of disease.

AB  - Major green tea catechin, epigallocatechin-3-gallate (EGCG), binds non-covalently to numerous dietary proteins, including beta-lactoglobulin of cow's milk. The effects of glycation of proteins via Maillard reaction on the binding capacity for polyphenols and the antiradical properties of the formed complexes have not been studied previously. Binding constant of BLG glycated by milk sugar lactose to EGCG was measured by the method of fluorophore quenching. Binding of EGCG was confirmed by CD and FTIR. The antioxidative properties of the complexes were examined by measuring ABTS radical scavenging capacity, superoxide anion scavenging capacity and total reducing power assay. Glycation of BLG does not significantly influence the binding constant of EGCG for the protein. Conformational changes were observed for both native and glycated BLG upon complexation with EGCG. Masking effect of polyphenol complexation on the antioxidative potential of the protein was of the similar degree for both glycated BLG and native BLG.
