    歯周炎症が、全身性に増幅される機序を脂肪細胞-マクロファージ相互作用の観点から検討する目的で、共培養系を確立し炎症脂肪組織における高発現遺伝子を網羅的に解析した結果、マクロファージと脂肪細胞の共培養系において、成熟樹状細胞を誘引するCCL19の遺伝子発現が亢進することを見出し、CCL19とその受容体CCR7に着目した。遺伝性・食餌性肥満マウスでは、LPS注入後の血清CCL19濃度が増大し、CCR7欠損マウスでは、食餌誘導性肥満およびインスリン抵抗性の発症が抑制され、アディポネクチン経路および熱産生が亢進した。この現象はエピカテキン (EC) を添加した高脂肪食負荷マウスにおいても観察された。また、脂肪組織において炎症細胞浸潤はみられず、CD11c陽性細胞は野生型マウスでのみ観察された。すなわち、CCL19-CCR7経路が成熟樹状細胞の脂肪組織への遊走・浸潤に関与し、アディポネクチンシグナルおよび熱産生機能の抑制を介して肥満、インスリン抵抗性の発症に関与することを世界に先駆けて示したことに新規性がある。

    Epicatechin (EC) intake appears to be beneficial for the prevention of cardiovascular disorders, and it is well known that adipose tissue inflammation is one of the major risk factors for coronary heart diseases. Additionally, periodontal inflammation has been suggested to accelerate cardiovascular risk via enhancing adipose tissue inflammation. The purpose of the present study was to determine the in vitro and in vivo effects of EC on adipose tissue inflammation and obesity.
    DNA microarray analysis was performed to evaluate the effects of EC on gene expression in adipocytes co-cultured with endotoxin-stimulated macrophages. To determine the in vivo effects, C57BL/6 mice were fed either a high-fat diet (HFD) or HFD combined with EC, and metabolic changes were observed.
    EC suppressed the expression of many inflammatory genes in the adipocytes co-cultured with endotoxin-stimulated macrophages. Specifically, EC markedly suppressed chemokine (C-C motif) ligand 19 (CCL19) expression. The in vivo study indicated that mice fed the EC-supplemented HFD were protected from diet-induced obesity and insulin resistance. The expression levels of genes associated with inflammation in adipose tissue and in the liver were downregulated in this group of mice.
    EC exerts beneficial effects for the prevention of adipose tissue inflammation and insulin resistance. Since the mice deficient in the CCL19 receptor were protected from diet-induced obesity and insulin resistance, the beneficial effects of EC could be mediated, at least in part, by marked suppression of CCL19 expression. Thus, EC may also exert beneficial effects against periodontal inflammation-associated augmentation of cardiovascular risk.

    BACKGROUND:
    The chemokine receptor CCR7, expressed on various immune cells, is associated with cell migration and lympho-node homing. Mice lacking Ccr7 are protected from diet-induced obesity and subsequent insulin resistance. We evaluated the mechanism underlying these protective effects from the standpoint of energy expenditure.
    METHODS:
    Wild-type and Ccr7 null mice were fed a high-fat diet, and the regulation of energy metabolism and energy metabolism-related molecules, e.g., Ucp1, Cidea, and Pgc1α, were evaluated.
    RESULTS:
    Food intake did not differ between groups. O2 consumption and CO2 production were higher in Ccr7 null mice than in wild-type mice, despite a similar respiratory quotient and glucose and lipid utilization, suggesting that energy expenditure increased in Ccr7 null mice via enhanced metabolism. In white adipose tissues of Ccr7 null mice, Prdm16, Cd137, Tmem26, Th, and Tbx1 expression increased. Similarly, in brown adipose tissues of Ccr7 null mice, Dio2, Pgc1α, Cidea, Sirt1, and Adiponectin expression increased. In both white and brown adipose tissues, Ucp1 gene and protein expression levels were higher in null mice than in wild-type mice.
    CONCLUSIONS:
    In Ccr7 null mice, browning of white adipocytes as well as the activation of brown adipocytes cause enhanced energy metabolism, resulting in protection against diet-induced obesity.

    Background and aims Epicatechin (EC) intake has been suggested to be beneficial for the prevention of cardiovascular disorders, and it is well known that adipose tissue inflammation is one of the major risk factors for coronary heart diseases. The purpose of the present study was to determine the in vitro and in vivo effects of EC on adipose tissue inflammation and obesity. Methods and results DNA microarray analysis was performed to evaluate the effects of EC on gene expression in adipocytes co-cultured with bacterial endotoxin-stimulated macrophages. To determine the in vivo effects of the catechin, C57BL/6 mice were fed either a high-fat diet (HFD) or HFD combined with EC, and metabolic changes were observed EC suppressed the expression of many inflammatory genes in the adipocytes co-cultured with endotoxin-stimulated macrophages. Specifically, EC markedly suppressed chemokine (C–C motif) ligand 19 (CCL19) expression. The target cell of EC appeared to macrophages. The in vivo study indicated that mice fed the EC-supplemented HFD were protected from diet-induced obesity and insulin resistance. Accordingly, the expression levels of genes associated with inflammation in adipose tissue and in the liver were downregulated in this group of mice. Conclusions EC exerts beneficial effects for the prevention of adipose tissue inflammation and insulin resistance. Since we previously reported that mice deficient in the CCL19 receptor were protected from diet-induced obesity and insulin resistance, it can be concluded that the beneficial effects of EC could be mediated, at least in part, by marked suppression of CCL19 expression.
