The objective of this study was to determine both membrane and intracellular expression of BAFF\/BAFFR in monocytes and B-cells in peripheral blood of 19 primary Sj\u00f6gren\u2019s syndrome patients and 20 healthy controls using flow cytometry. We also measured sBAFF in serum. Compared to healthy controls, both surface and intracellular expression of BAFF was significantly increased in monocytes and B-cells of SjS patients. Also serum sBAFF level was elevated. Expression of BAFFR on B-cells of SjS patients was surprisingly decreased, but there was no clear increase or decrease within monocytes. Our results indicate that activated monocytes communicate with B-cells via BAFF and BAFFR, so that B-cells are stimulated, but BAFF is also produced to stimulate cells in autocrine way. The decrease of BAFFR expression in SjS patients suggests that there is the mechanism that attempts to take over in order to balance the high level of BAFF.<\/jats:p>","DOI":"10.14712\/18059694.2015.88","type":"journal-article","created":{"date-parts":[[2015,7,9]],"date-time":"2015-07-09T08:13:15Z","timestamp":1436429595000},"page":"25-31","source":"Crossref","is-referenced-by-count":3,"title":["Increase
