Abstract
Background: The availability of glucose in tissue has a role in macrophages polarisation into an inflammatory phenotype. The overnutrition condition such as hyperglycaemia induces macrophage infiltration especially the inflammatory macrophages. The aim of this study was to analyse the effect of hyperglycaemia condition on cytokines production by human monocytes-derived macrophages.
Materials and methods: Monocyte cells obtained from peripheral blood mononuclear cells isolation from donors were incubated for 6 days in 37°C, 5% CO2. On day 4, the stimulating factors such as lipopolysaccharide (LPS) and interferon gamma were added to activate monocytes into macrophages. Then, on day 6, two doses of glucose; either normal or high doses along with low or high dose of LPS were given for 24 h, followed by collecting the culture media and cells then stored at −80°C until assayed.
Results: There was a significant difference in tumour necrosis factor alpha (TNF-a) levels among groups, with highest level found in group with high-dose glucose plus high-dose LPS. However, the concentration of interleukin-6 (IL-6) among groups was not significantly different.
Conclusions: Macrophages treated with high-dose glucose plus high-dose LPS significantly increased production of TNF-a, but not of IL-6.
