To establish a model for 1,25-(OH)2D3 regulation of human monocyte monokine synthesis , three human cell lines ( U-937 , THP-1 , and HL-60 ) were examined for: 1) the presence of functional 1,25-(OH)2D3 receptors; 2) the accumulation of interleukin-1 beta ( IL-1 beta ) mRNA and IL-1 beta protein in response to lipopolysaccharide ( LPS ); and 3) the regulation of this response by 1,25-(OH)2D3 .
