AIMS We investigated the mechanism by which cannabinoid receptors-1 (CB1) and -2 (CB2) modulate inflammatory activities of macrophages. METHODS AND RESULTS Real-time polymerase chain reaction showed the predominant CB2 expression in freshly isolated human monocytes. PMA, a potent inducer of differentiation, upregulated CB1 and increased CB1:CB2 transcript(More)
OBJECTIVES We investigated the mechanism by which C-reactive protein (CRP) affects pro-inflammatory activities of vascular smooth muscle cells (VSMCs). METHODS AND RESULTS RT-PCR, flow cytometry, and immunoblotting assays consistently showed the expression of FcgammaRIIa by cultured VSMCs isolated from human coronary arteries. Immunofluorescence staining(More)
OBJECTIVES A recent study suggested a prognostic role for the peripheral blood absolute lymphocyte/monocyte ratio (LMR) at diagnosis of diffuse large B-cell lymphoma (DLBCL). Here, we investigated the significance of LMR in DLBCL patients in relation to advanced age. METHODS We examined the prognostic impact of LMR in 603 DLBCL treated with rituximab plus(More)
Multiple myeloma (MM) is characterized by clonal expansion of malignant bone marrow cells producing a unique monoclonal immunoglobulin. The appearance of abnormal protein band (APB) in MM has been reported during follow-up. We aimed to evaluate the clinical characteristics and outcomes of patients with APB in a single center cohort. A total of 377(More)
The germinal centre is a dynamic microenvironment where antigen-activated B cells rapidly expand and differentiate, generating plasma cells and memory B cells. These cellular events are accompanied by dramatic changes in the antibody molecules that undergo somatic hypermutation and isotype switching. Follicular dendritic cells (FDCs) are the stromal cells(More)
OBJECTIVE The clinical features of extranodal natural killer (NK)/T-cell lymphoma (ENKL) that originates in extranasal sites are less well defined than those of ENKL that originates in nasal sites. Therefore, we compared the clinical characteristics and prognoses of patients with nasal ENKL and patients with extranasal ENKL. METHODS We retrospectively(More)
Diffuse large B-cell lymphoma (DLBCL) can be separated into 2 groups: nodal and extranodal disease. The aim of this study was to analyse the clinical features of skin lesions and survival outcomes of cutaneous DLBCL according to the primary tumour site. A total of 44 patients with cutaneous DLBCL were classified as primary cutaneous DLBCL, leg type or(More)
B cell-activating factor of the tumor necrosis factor family (BAFF/BLys) plays a critical role in B cell survival and immune responses through its three receptors: BAFF receptor (BAFF-R/BR3), transmembrane activator and calcium modulator and cyclophilin ligand interactor (TACI) and B cell maturation antigen (BCMA). Using specific antibodies, we have(More)
BACKGROUND Primary central nervous system lymphoma (PCNSL) rarely relapses in extracranial sites, and no specialized guidelines for follow-up evaluation have been proposed. METHODS We analyzed 65 patients with newly diagnosed PNCSL to evaluate the pattern of relapse and prognostic factors. RESULTS Of the 65 patients analyzed, 55 had only parenchymal(More)
The gastrointestinal tract is the most common primary extranodal site for diffuse large B-cell lymphoma (DLBCL). However, there is no consensus on the most appropriate staging system for intestinal DLBCL. We evaluated the utility of the modified Ann Arbor system, the Lugano system, and the Paris staging system (a modification of the Tumor, Node, Metastases(More)
