Originální abstrakt

Interleukin-1 beta (IL-1 beta) belongs among proinflammatory cytokines that are produced by activated macrophages as an immune response of the organism. Therefore, IL-1 beta could serve as a possible biomarker of a bacterial infection caused by Actinobacillus pleuropneumonia. In this study, we applied matrix assisted laser desorption/ionization mass spectrometry imaging (MALDI MSI) together with immunohistochemical analyses (IHC) using primary antibody anti-IL-1 beta for IL-1 beta detection in cryo-sectioned pulmonary tissues. Using MALDI MSI, we detected and spatially visualized the tryptic fragment of IL-1 beta. This IL-1 beta tryptic fragment was more frequently detected in infected pulmonary tissues compared to healthy pulmonary tissue except one necrotic lung tissue where was not revealed the statistically significant difference. IHC confirmed the occurrence of IL-1 beta in necrotic pulmonary tissues. This knowledge could be useful for further clinical studying as a targeted therapy.
