The effect of interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) on granulocyte macrophage-colony stimulating factor (GM-CSF) production by neuronal precursor cells.
Eur Cytokine Netw. 2002 Jan-Mar; 13(1):128-33.EC

Abstract

AIMS

To determine whether granulocyte macrophage-colony stimulating factor (GM-CSF) production by neuronal precursor (NT2) cells can be regulated by IL-1beta and TNF-alpha.

BACKGROUND

We have previously demonstrated GM-CSF expression by neurons of the developing human brain, as well as by NT2 cells. IL-1beta and TNF-alpha upregulate GM-CSF production in glial cells, but GM-CSF regulation in neurons is as yet undefined. We hypothesized that IL-1beta and TNF-alpha would increase GM-CSF mRNA and protein production in NT2 cells.

METHODS

The effect of IL-1beta and TNF-alpha on GM-CSF production was assessed by dose response (0 to 2,000 U/ml), and time course (0 to 48 hours incubation) experiments. GM-CSF mRNA and protein production were assessed by quantitative RT-PCR and by ELISA. The effect of these cytokines on cell turnover was determined by BrdU incorporation.

RESULTS

IL-1beta increased GM-CSF mRNA and protein expression by NT2 cells. This effect was time and dose dependent, and the effective dose ranging from (20-200 U/ml). TNF-alpha increased GM-CSF mRNA expression to a lesser extent than did IL-1beta (maximal stimulation at 200 U/ml), and a minimal increase in net protein accumulation was noted. Neither cytokine increased NT2 cell turnover.

CONCLUSIONS

IL-1beta and TNF-alpha both increase GM-CSF mRNA expression by NT2 cells, but only IL-1beta increases net GM-CSF protein accumulation.
