Figure 3 .

Expression of IL-1β protein by LPS stimulated lamina propria cells isolated from normal and IBD colonic mucosa. Cell lysates and supernatants were studied by western blot analysis. In cells obtained from IBD colon, both 31 kD and 17 kD forms of the cytokine were detected in the supernatants. The figure shows representative experiments performed on lamina propria cells obtained from four normal and five IBD colons.
