An IL-10 homologue encoded by human cytomegalovirus is linked with the viral “footprint” in clinical samples
Persistent infections with human cytomegalovirus (HCMV) affect the hosts’ immune system and have been linked with chronic inflammation and cardiovascular disease. These effects may be influenced by a HCMV-encoded homologue of the anti-inflammatory cytokine, IL-10 (cmvIL-10). To assess this, we quantitated cmvIL-10 in plasma from renal transplant recipients (RTR) and healthy adults.
Detectable levels of cmvIL-10 associated with seropositivity in RTR, but were found in some seronegative healthy adults. RTR with detectable cmvIL-10 had elevated interferon-γ T-cell responses to HCMV antigens, whilst cmvIL-10 in healthy adults associated with reduced populations of terminally-differentiated T-cells – a known “footprint” of HCMV. Plasma cmvIL-10 associated with lower VCAM-1 levels in healthy adults.
The data suggest cmvIL-10 may suppress seroconversion and/or reduce the footprint of HCMV in healthy adults. This appears to be subverted in RTR by their high burden of HCMV and/or immune dysregulation associated with transplantation. A role for cmvIL-10 in protection of vascular health is discussed.
期刊介绍：
The journal Cytokine has an open access mirror journal Cytokine: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
* Devoted exclusively to the study of the molecular biology, genetics, biochemistry, immunology, genome-wide association studies, pathobiology, diagnostic and clinical applications of all known interleukins, hematopoietic factors, growth factors, cytotoxins, interferons, new cytokines, and chemokines, Cytokine provides comprehensive coverage of cytokines and their mechanisms of actions, 12 times a year by publishing original high quality refereed scientific papers from prominent investigators in both the academic and industrial sectors.
We will publish 3 major types of manuscripts:
1) Original manuscripts describing research results.
2) Basic and clinical reviews describing cytokine actions and regulation.
3) Short commentaries/perspectives on recently published aspects of cytokines, pathogenesis and clinical results.
