Cím:	Effect of plasmapheresis on ligand binding capacity and expression of erythrocyte complement receptor type 1 (CR1) of patients with systemic lupus erythematosus (SLE) / I. Csipő, E. Kiss, P. Soltész, P. Antal-Szalmás, Gy. Szegedi, J. H. M. Cohen, R. P. Taylor, M. Kávai

Megjegyzések:	The functional activity and the expression of CR1 on the erythrocytes (E) of patients with SLE were, respectively, determined by measuring the binding to E of either complement-opsonized bovine serum albumin (BSA)-anti-BSA immune complexes (ICC) or specific anti-ECR1 MoAbs. We found that both the functional activity and levels of ECR1 in SLE patients homozygous for ECR1 high density allele were significantly lowered compared with healthy controls having the same allele. Soon after plasmapheresis there was a significant increase in E ICC binding activity, and this increased functional activity was stable. Moreover, plasmapheresis reduced the level of immune complexes demonstrable in the circulation of the patients. The expression of ECR1 determined with several different anti-CR1 MoAbs was also elevated as a consequence of plasmapheresis. This elevation was observed for both MoAb 1B4, which competes for the ICC binding site of ECR1, and for MoAb HB8592, which does not, but the time course for the increase in binding of the two MoAbs was different, in that the epitope recognized by MoAb 1B4 increased more rapidly. The present results, considered in the context of previous findings, suggest that more than one mechanism may be operative with respect to the effects of the plasmapheresis in increasing ECR1 levels defined by different epitopes on the molecule.

Cím:	Glucocorticosteroid therapy decreases CD14-expression and CD14-mediated LPS-binding and activation of monocytes in patients suffering from systemic lupus erythematosus / Andrea Sümegi, Péter Antal-Szalmás, Magdolna Aleksza, Ildikó Kovács, Sándor Sipka, Margit Zeher, Emese Kiss, Gyula Szegedi

Megjegyzések:	In order to study the possible action of glucocorticosteroids (GCS) on the CD14/Toll like receptor mediated activation of monocytes the CD14-expression, CD14-mediated LPS binding and activation of these cells of patients suffering from Systemic Lupus Erythematosus receiving no, low dose or pulse steroid treatment was studied. The CD14-expression was determined on whole blood monocytes by flow cytometry, while the LPS-binding of an FITC-LPS preparate and the LPS-induced TNFalpha secretion were tested on isolated monocytes. The CD14-dependent and -independent LPS-binding and activation were evaluated with the help of a blocking anti-CD14 mAb. Our results showed that the CD14-expression, CD14-dependent LPS-binding and activation were significantly inhibited by the in vivo applied pulse steroid therapy. In contrast, the CD14-independent LPS-binding and activation were not altered by the GCS treatment. Our data provide further in vivo evidence for a possible new way of GCS therapy is able to initiate its anti-inflammatory action.
