Interleukin-6 Signaling, Soluble Glycoprotein 130, and Inflammation in Heart Failure


Both experimental and clinical evidence accumulated over the last couple of decades has linked inflammatory activation to the initiation and progression of chronic heart failure (HF). Circulating levels of inflammatory mediators are associated with cardiac function and inform risk prediction in patients, but the effect of anti-inflammatory therapy in HF remains uncertain. Interleukin (IL)-6 type cytokines are central to the inflammatory response, and convey their signals through the ubiquitously expressed glycoprotein (gp) 130 receptor subunit. IL-6-type/gp130 signaling therefore represents an inflammatory nexus, with inherent potential for disease modification. This review focuses on the current knowledge of IL-6/gp130 signaling in relation to HF, with a particular emphasis on the role of soluble gp130 (sgp130), a signaling pathway modulator. Biological aspects of sgp130 and IL-6 signaling are discussed, as are potential novel therapeutic approaches to modulate this central inflammatory signaling pathway.

The interleukin-6 receptor as a target for prevention of coronary heart disease: a mendelian randomisation analysis. Lancet. 2012;379(9822):1214–24. This pivotal paper co-contributed the first causal link between IL-6 signaling and CV disease. Through single-nucleotide polymorphism (SNP) analyses of the IL6R gene in 133,000 individuals, an IL6R variant (Asp358Ala) was found to protect against coronary artery disease, with effects on circulating IL-6, CRP and fibrinogen concentrations similar to that of tocilizumab in clinical trials.

This pivotal paper co-contributed the first causal link between IL-6 signaling and CV disease. An IL6R variant (Asp358Ala) was associated with increased circulating IL6R and IL6, and reduced CRP and fibrinogen in 125,000 participants. For every copy of 358Ala, the inherited the risk of coronary heart disease was reduced by 3.4 %.

Arterioscler Thromb Vasc Biol. 2011;32(2):281–90. This elegant experimental study demonstrated that inhibition of IL6 trans-signaling with an sgp130Fc fusion protein can dramatically reduce, and even reverse, atherosclerosis in mice. Importantly, sgp130FC did not increase serum lipid levels, a common occurrence with tocilizumab treatment.
