Here , we show that zinc addition in a serum- and lipopolysaccharide-free cell culture system leads to significantly enhanced levels of interleukin 1 beta ( IL-1 beta ) and tumour necrosis factor alpha ( TNF-alpha ) and to expression of the corresponding mRNA in human peripheral blood mononuclear cells ( PBMC ) .
