Syndecan-expresszió és a lymphoid rendszer

Research output: Contribution to journalArticle


Syndecans, transmembrane heparan sulfate proteoglycans, play an important role in cell-cell and cell-matrix interactions, as receptors/co-receptors of matrix elements, cytokines, growth factors. These functions are partly non-specific and due to the heparan sulfate chains attached to the ectodomain, and partly specific related to the transmembrane and cytoplasmic domains of the core protein. In hemopoietic cells syndecan-1 is expressed in certain B cells, in pre-B cells and plasma cells. In lymphoproliferative diseases this normal syndecan-1 expression of plasma cells is retained in myelomas/plasmocytomas, other lymphoplasmocytic NHL subtypes and primary effusional lymphomas. Syndecan-1 expression is probably gained in B-CLL, and lost in other NHLs of pre- or post-follicular origin. These results suggest that the expression of syndecan is essential for some NHLs, probably ensuring the required connections to the microenvironment. From a diagnostic point of view, syndecan-1 is a very useful phenotypic marker to identify cells with plasmocytic differentiation. The importance of syndecan expression in CLL and Hodgkin-lymphoma still requires further studies.
