Changes in the serum proteome profile of patients with neuroborreliosis, foresters, and patients treated according to ILADS method

Abstract

ObjectivesThe aim of study was to evaluate the changes in proteomic profile of human serum induced by the development of tick-borne neuroborreliosis (NB), before/after therapy, patients treated with prolonged multidrug therapy according to ILADS (International Lyme and Associated Diseases Society), and foresters frequently exposed to tick bites. MethodsA proteomics approach was used to analyze the expression of proteins in serum of patients and sex/age-matched healthy donors. The analysis was performed using SDS-PAGE/LC-MS/MS (Q-Exactive OrbiTrap mass spectrometer). ResultsObtained results indicated changes in the serum proteome of patients with NB putting attention to the proteins involved mainly in calcium transport/metabolism and signaling molecules that differ patients before and after classic therapy. Moreover, ILADS treated patients have different protein distribution than patients from other groups, what is the consequence of prolonged antibiotic therapy. In the case of foresters, the most important result is the increased β-secretase level. ConclusionsObtained results may contribute to a better understanding of the mechanism of the development of tick-borne diseases, as well as will allow create new opportunities for its rapid and more effective therapy. However, further studies, on larger patients groups, are needed to apply them in clinical practice.
