Sažetak
The majority of environmental diseases are multifactorial airway illnesses, including genetic background and exposure to different kind of airborne irritants and allergens. Altered lifestyle and changes in environmental exposures contribute to the occurring of these diseases. The term of environmental illnesses includes the disease primarily caused by pollution of air and water, chemical and physical agents, radiation, contaminated food and direct contact with the toxins we are exposed to natural and/or working environment. The members of the matrix metalloproteinase (MMP) family are involved in the pathogenesis of COPD. MMPs comprise a large family of structurally related zinc metalloendopeptidases with different substrate specificities and possibilities to degrade protein constituents of the extracellular matrix. We investigated immunological status and level of MMP-9 in workers occupationally exposed to volatile aromatic hydrocarbons compared to urban residents and rural areas. The phenotypic profiles of peripheral blood lymphocytes were done by flow cytometry. The method of enzyme immunoassay (ELISA) was used to determine enzyme expression of matrix metalloproteinase-9 (MMP-9). The occupationally exposed group had a significantly elevated level of enzyme MMP-9 in the urine, accompanied with augmentation of cells of innate immunity in peripheral blood, which could contribute to the monitoring, early detection of environmental diseases and consequent earlier and more effective treatment.
