Abstract

Objective. To study of known interferons (IFN) type I and IFN-inductors drugs different chemical structure on cell differentiation and expression group of genes of TLR/RLRs, referring to group of pattern-recognition receptors. Materials and methods. Cellular lines ТНР-1 (acute monocytic leukemia) и НСТ-116 (colon adenocarcinoma) were treated by interferons drugs Reaferon, Altevir, Genfakson, Infibeta 10⁵-10⁶ МЕ, IFN-inductors Ridostin 10²-10³ ßg/ml, Cycloferon 625 ßg/ml and Imunomax 2 МЕ during 24 h or 96 h at 37 °С. Gene expression were estimated by method qRT-PCR (CFX-96, Bio-Rad). CD-immuno-phenotypes of ТНР-1 cells were detected by flow cytometric fluorescence method with FITC and PE monoclonal antibodies (FACSCanto II, Becton Dickinson). Results. It was shown that tumor cells THP-1 and HCT-116 have low and variable constitutive levels gene expression of TLR-receptors 2, 3, 4, 7, 8, 9 during passages. This gene status may be connected with incorrect processing of mature mRNA forms. Genes TLR4, TLR8 and factor NFkB are stimulated by interferons and IFN-inductors more high in THP-cells and genes TLR7, TLR8, TLR9 and NFkB - in HCT-cells. Ridostin (mix ssRNA and dsRNA S. cerevisiae) is the best activator of TLR/RLRs receptors. Ridostin increases macrophage marker CD11b, Cycloferon, Imunomax stimulate levels of early T-cell antigen CD7, interferons results in growth of HLA DR. The drugs Cycloferon, Imunomax and Reaferon decrease levels of myeloid suppressor CD38. Conclusion. Group of recombinant IFNs and IFN-inductor drugs various chemical structures regulate TLR/RLRs genes expression differently in THP-1 and HCT-116. TLR/RLRs genes activation are accompanied by CD-phenotypes changes in THP-1 monocytic cell line.
