We have recently shown that the blood cell-derived secretome of remote ischaemic (RIC)-conditioned individuals provides an external source of neuroprotection. In this study, we identified the bioactive compounds from the total proteins released by those cells. Our main strategy was to separate protein–protein complexes while maintaining their native structure and testing their bioactive properties. Subsequently, we identified up- and downregulated bioactive proteins. We uncovered two bioactive fractions composed of 18 proteins. Most of the protein peaks were unchanged; however, RIC mediated a decrease in two peaks (comprising seven proteins) and an increase in one peak (identified as haptoglobin). When focussing on the biological activity of these proteins, we found positive impacts on the regulation of cellular metabolic processes and an increase in biological processes related to the acute phase response and inflammation in the RIC-treated samples. Although we have identified the 18 proteins that exert the greatest cytoprotection, additional studies are needed to elucidate their particular function and detailed mechanisms of action. |
