The effects of short- and long-term HighGlu on IL-1β secretion and LPS/cytokine receptor expression. Bone marrow cells were cultured for 7 days under NormGlu (white bars) or HighGlu (black bars) conditions. They were then plated and stimulated with LPS + IFNγ (M1) for 24 h. For short-term HighGlu, cells differentiated under NormGlu, were exposed to HighGlu for 24 h along with M1 stimulation. a-b ELISA showing the levels of IL-1β in the supernatants of M1 BMDMs exposed to short-term (a) or long-term (b) HighGlu. c-d qRT-PCR showing the expression of LPS and cytokine receptors in naïve BMDMs exposed to short-term (c) or long-term (d) HighGlu. Data are represented as mean ± SEM. Unpaired, two-tailed Student’s t test was performed. * p < 0.05, ** p < 0.01
