Abstract
The objective of this project is to determine whether there is an imbalance between cysteine proteinases cathepsins B, H, L and S, and their low molecular weight inhibitors stefins A and B, and cystatin C in asthmatic sera compared to controls. We are interested whether there is a relationship between the concentrations and molar ratios of these serum proteins to blood number of eosinophils (EOS), serum concentrations of eosinophil cationic protein (ECP) and myeloperoxidase (MPO), and peak expiratory flow rate (PEF) in healthy subjects, steroid-independent and steroid-dependent asthmatic patients. The purpose is also to establish the differences between normal serum and plasma concentrations in order to exclude intracellular contribution from platelets to the measured values in serum and to get more clear information on how the specimen collection affects the preanalytical variation of blood cysteine proteinases and their inhibitors. We will evaluate also the possibility that serum cysteine proteinases and their inhibitors correlate with the response to therapy with methylprednisolone in steroid-independent asthmatic patients, and to cyclosporin A in steroid-dependent asthmatic patients. Besides we will perform immunocyto/immunohistochemical studies in clinical samples of asthmatic patients in order to get some information of their localisation. These results may provide better understanding of the role of cysteine proteinases and their inhibitors in pathophysiological mechanisms of asthma and may be of clinical interest for the evaluation of these serum proteins as additional biochemical parameters for monitoring the disease and the response to therapy.
