A rhesus macaque rhadinovirus related to Kaposi's sarcoma-associated herpesvirus/human herpesvirus 8 encodes a functional homologue of interleukin-6.
The rhesus rhadinovirus strain 17577 (RRV strain 17577) genome is essentially colinear with human herpesvirus 8 (HHV8)/Kaposi's sarcoma-associated herpesvirus (KSHV) and encodes several analogous open reading frames (ORFs), including the homologue of cellular interleukin-6 (IL-6). To determine if the RRV IL-6-like ORF (RvIL-6) is biologically functional, it was expressed either transiently in C...
متن کاملTranscriptional regulation of the interleukin-6 gene of human herpesvirus 8 (Kaposi's sarcoma-associated herpesvirus).
Human herpesvirus 8 (HHV-8; Kaposi's sarcoma-associated herpesvirus is linked to Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), and multicentric Castleman's disease (MCD), all of which are viewed as cytokine-driven malignancies. In particular, interleukin-6 (IL-6) has been found to promote the growth and proliferation of cells from KS and PEL. HHV-8 encodes a homologue of IL-6 (viral I...
متن کاملRta of the human herpesvirus 8/Kaposi sarcoma-associated herpesvirus up-regulates human interleukin-6 gene expression.
Human herpesvirus 8 (HHV-8)/Kaposi sarcoma-associated herpesvirus (KSHV) is linked to a number of malignancies thought to be driven by cytokines, including interleukin-6 (IL-6). Rta, a transcriptional activator encoded by HHV-8/KSHV, activates the viral lytic cycle leading to the expression of several viral genes implicated in viral pathogenesis. However, the effect of HHV-8/KSHV Rta on cellula...
متن کاملHuman herpesvirus type 8 interleukin-6 homologue is functionally active on human myeloma cells.
Seroepidemiology and polymerase chain reaction studies have strongly suggested that human herpesvirus type 8 (HHV-8) is associated with Kaposi's sarcoma, Castleman's disease, and body cavity-based lymphoma. The genome of HHV-8 harbors a viral analogue of the interleukin-6 (IL-6) gene. The amino acid sequence of the viral IL-6 (vIL-6) protein is 24.7% identical to human IL-6 (hIL-6). IL-6 as a B...
متن کاملDeterminants of secretion and intracellular localization of human herpesvirus 8 interleukin-6.
Human herpesvirus 8 (HHV-8) interleukin-6 (vIL-6) is distinct from human and other cellular IL-6 proteins in that it does not require the nonsignaling alpha-receptor subunit for the formation of gp130-based signal transducing complexes and also is largely retained intracellularly rather than being secreted. We and others have reported that vIL-6 is retained and is active in the endoplasmic reti...
