Sažetak
Hantaviruses cause two important human illnesses, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). Both syndromes are believed to be immune-mediated diseases. Monocytes/macrophages are thought to be the main target cells for hantaviruses and important sources of and targets for cytokines/chemokines secretion. THP-1 cells have been used extensively as models for primary monocytes in biocompatibility research. The aim of our study was to determine if hantaviruses induce the same immunoreactions in THP-1 cells and primary monocytes/ macrophages and might therefore be suitable for immune studies of hantaviral infections. For that purpose we compared various cytokines/chemokines and their receptors in THP-1 cell line and primary monocytes/macrophages. Infected primary monocytes/macrophages induced mostly beta-chemokines and their receptors. In contrast, THP-1 cells, expressed receptors for CXC chemokines. Surprisingly, infected macrophages underwent morphological changes toward dendritic-like cells and increased expression of co-stimulatory molecules: CD40, CD80, CD83 and CD86. Our data indicate that THP-1 cells are not ideal for in vitro research of the immunopathogenesis of hantaviruses in humans. Further, our studies revealed potential roles for cytokines/chemokines in HFRS/HPS immunopathogenesis and point to intriguing possibilities for the possible differentiation of infected macrophages to dendritic-like cells.
