Human herpesvirus 8 (HHV-8) virus interleukin-6 (vIL-6) is a cytokine that is secreted and most poorly translated into the endoplasmic reticulum (ER). Has been involved, along with HHV-8 viral proteins pro-inflammatory and / or other angiogenic, in HHV-8-related Kaposi’s sarcoma, primary effusion lymphoma (PEL), and multicentric Castleman’s disease (MCD), in addition to an MCD -related disorders involving elevation of systemic pro-inflammatory cytokines, including human vIL-6 and IL-6 (HIL-6). In this disease, lytic (productive) replication, in addition to viral latency, is believed to play an important role.
Pro-replication activity of vIL-6 has been identified experimentally in PEL and endothelial cells, but the relative contribution of different vIL-6 interaction has not been established. productive interaction of vIL-6 to IL-6 signal transducer, gp130, can occur in the ER, but vIL-6 also interact in the ER with a receptor called vitamin K epoxide non-signal reductase subunit complex 1 variant-2 (VKORC1v2), calnexin, and VKORC1v2- and related calnexin protein UDP-glucose: glycoprotein glucosyltransferase 1 (UGGT1) and glucosidase II (GlucII). Here, we report a systematic characterization of the interaction-modified vIL-6 variants and recombinant virus expressing the lytic phenotype selected variants.
Our data identifies the importance of vIL-6 and the activity of ER-localized it through gp130 to replicate productively in iSLK (induced epithelial) cells, the lack of involvement of detectable vIL-6 interaction with VKORC1v2, GlucII or UGGT1, and the insufficiency and lack of effect of direct contributions from extracellular signals by vIL-6 or Hil-6. These findings, obtained through genetic-based approach, complementing and extending the previous analysis of vIL-6 activity.IMPORTANCE Human herpesvirus 8 (HHV-8) -encoded viral interleukin-6 (vIL-6) was the first viral IL-6 homologues to be identified.
Experimental and clinical evidence indicates that vIL-6 is important for the onset and / or progression of the pathology associated with HHV-8 B-cells, and endothelial, including AIDS-related Kaposi’s sarcoma and multicentric Castleman’s disease. Protein is unusual in poor secretion of the cells and the intracellular activity; interact, directly or indirectly, with a number of outer protein IL-6 signal transducer, gp130, and may mediate this interaction activities through the endoplasmic reticulum.
Here, we characterize in connection with protein interactions and signal transducing activity of vIL-6 variant panels and take advantage of HHV-8 virus mutants expressing variant selected in the phenotypic analysis. Our findings establish the importance of vIL-6 in HHV-8 replication productive and individual contributions interaction of vIL-6 protein to HHV-8 lytic biology. This work furthers the understanding of the biological importance of vIL-6 and a unique intracellular interactions.
Genetic Analyses of Contributions of Viral Interleukin-6 Interactions and Signaling to Human Herpesvirus 8 Productive Replication
Impact of interleukin IL-6 rs-1474347 and IL-10-rs 1800896 susceptibility genetic polymorphisms in Egypt HCV-infected patients to hepatocellular carcinoma
The hepatitis C virus (HCV) is considered a major cause of cirrhosis and hepatocellular carcinoma (HCC). We aimed to determine the relationship of IL-6 and IL-10 single nucleotide polymorphisms with the development of chronic hepatitis C (CHC) infection to cirrhosis and liver cancer.

For comparison purposes, the four groups were registered; groups of chronic hepatitis C (CHC, n = 22), related to HCV-group liver cirrhosis (HCV-LC, n = 22), related to HCV-group of HCC (HCV-HCC, n = 54), and a control group that looked healthy (control , n = 48). HCC diagnosis and staging are in concordance to the Barcelona Clinic Liver Cancer (BCLC) staging system. IL-6 rs-1474347 and IL-10-rs 1800896 genotype performed by allele (VIC- and FAM-labeled) discrimination method using test-on-demand real-time TaqMan PCR test.
