Outline of Final Research Achievements |
To understand the molecular basis for the establishment of systemic low-grade inflammation caused by periodontal disease, close interaction between infiltrated macrophages and resident tissue cells was analyzed. Following results were obtained; i) inflammatory adipose tissue expressed chemokine ccl19, and the major source of ccl19 was enlarged adipocyte, 2) mice lacking ccl19 receptor were protected from diet-induced obesity and insulin resistance, 3) these mice were characterized by increased thermogenesis when compared with wild type control mice, 4) when the interaction between infiltrated macrophages and islet resident cells were analyzed, infiltration of endotoxin-activated macrophages up-regulated the expression of apoptosis inducing molecules.
