Differences of IL-1β Receptors Expression by Immunocompetent Cells Subsets in Rheumatoid Arthritis

Table 2

Balance between IL-1β receptors types 1 and 2 in terms of expression of membrane-bound forms of receptors on intact cells and monocytes in 24 h spontaneous and LPS-stimulated PBMC cultures in healthy individuals and in patients with rheumatoid arthritis in the acute phase ( = 33) and after response to treatment ( = 23). Each table cell indicates the more highly expressed receptor for a selected subpopulation in a studied group. “=” denotes that no significant difference in receptor expression was observed.
