ZYM-201 is a methyl ester of triterpenoid glycoside from Sanguisorba officinalis which has been used for treatment of inflammatory and metabolic diseases. In this study, immunomodulatory effects of ZYM-201 on B cells were examined in vitro and in vivo. When splenocytes were activated with lipopolysaccharide (LPS), the major population which had shown an(More)
In this study, we compared the immune cell populations in rheumatoid arthritis (RA) synovial fluid, which shows lymphoid tissue-like structure, with those in tonsils, which are normal secondary lymphoid tissues. Firstly, we found that CD4(-)CD11b(+) macrophages were the major population in RA synovial fluid and that B cells were the major population in(More)
The cellular prion protein is expressed in almost all tissues, including the central nervous system and lymphoid tissues. To investigate the effects of the prion protein in lymphoid cells and spleen structure formation, we used prion protein-deficient (Prnp(0/0)) Zürich I mice generated by inactivation of the Prnp gene. Prnp(0/0) mice had decreased(More)
