Megjegyzések:	Background: Utilization of quantitative proteomics data on the network level is still a challenge in proteomics data analysis. Currently existing models use sophisticated, sometimes hard to implement analysis techniques. Our aim was to generate a relatively simple strategy for quantitative proteomics data analysis in order to utilize as much of the data generated in a proteomics experiment as possible. Results: In this study, we applied label-free proteomics, and generated a network model utilizing both qualitative, and quantitative data, in order to examine the early host response to Human Immunodeficiency Virus type 1 (HIV-1). A weighted network model was generated based on the amount of proteins measured by mass spectrometry, and analysis of weighted networks and functional sub-networks revealed upregulation of proteins involved in translation, transcription, and DNA condensation in the early phase of the viral life-cycle. Conclusion: A relatively simple strategy for network analysis was created and applied to examine the effect of HIV-1 on host cellular proteome. We believe that our model may prove beneficial in creating algorithms, allowing for both quantitative and qualitative studies of proteome change in various biological and pathological processes by quantitative mass spectrometry.

Megjegyzések:	Background The healthy human skin with its effective antimicrobial defense system forms an efficient barrier againstinvading pathogens. There is evidence suggesting that the composition of this chemical barrier varies between diseases,making the easily collected sweat an ideal candidate for biomarker discoveries.Objective Our aim was to provide information about the normal composition of the sweat, and to study the chemicalbarrier found at the surface of skin.Methods Sweat samples from healthy individuals were collected during sauna bathing, and the global protein panelwas analysed by label-free mass spectrometry. SRM-based targeted proteomic methods were designed and stableisotope labelled reference peptides were used for method validation.Results Ninety-five sweat proteins were identified, 20 of them were novel proteins. It was shown that dermcidin is themost abundant sweat protein, and along with apolipoprotein D, clusterin, prolactin-inducible protein and serum albumin,they make up 91% of secreted sweat proteins. The roles of these highly abundant proteins were reviewed; all of whichhave protective functions, highlighting the importance of sweat glands in composing the first line of innate immunedefense system, and maintaining the epidermal barrier integrity.Conclusion Our findings with regard to the proteins forming the chemical barrier of the skin as determined by label-freequantification and targeted proteomics methods are in accordance with previous studies, and can be further used as astarting point for non-invasive sweat biomarker research.
