We have recently shown that cannabinoids induce growth inhibition and apoptosis in mantle cell lymphoma (MCL), a malignant B-cell lymphoma that expresses high levels of cannabinoid receptor types 1 and 2 (CB(1) and CB(2)). In the current study, the role of each receptor and the signal transduction
The peripheral cannabinoid receptor CB2 is expressed highly on normal human B-lymphocytes. C-terminal specific anti-CB2 antibody recognises a non-phosphorylated inactive receptor on naïve and resting B-lymphocytes. Another, N-terminal specific CB2 antibody, primarily recognises B-cells present in
BACKGROUND
The peripheral cannabinoid receptor (CB2) is mainly detected on B cells in the germinal centers (GCs) of the immune system, using an antibody directed against the extra cellular N-terminal domain of the receptor. We retrospectively investigated the CB2 receptor expression in diffuse large
The initiating oncogenic event in mantle cell lymphoma (MCL) is the translocation of cyclin D1, t(11;14)(q13;q32). However, other genetic aberrations are necessary for an overt lymphoma to arise. Like other B cell lymphomas, MCL at some points during the oncogenesis is dependent on interactions with
Hodgkin lymphoma (HL) is one of the most curable malignancies. Despite its effectiveness, chemotherapy is often associated with adverse events (AEs) such as nausea, anorexia, and impairment of general well-being. Our objective was to assess the extent of medical cannabis use among HL patients and
Ceramide levels are elevated in mantle cell lymphoma (MCL) cells following treatment with cannabinoids. Here, we investigated the pathways of ceramide accumulation in the MCL cell line Rec-1 using the stable endocannabinoid analogue R(+)-methanandamide (R-MA). We further interfered with the
Cannabis sativa produces hundreds of phytocannabinoids and terpenes. Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma (CTCL), characterized by patches, plaques and tumors. Sézary is a leukemic stage of CTCL presenting with erythroderma and the presence of neoplastic
BACKGROUND
Cannabinoid receptor 1 (CB1) is expressed in certain types of malignancies. An analysis of CB1 expression and function in Hodgkin lymphoma (HL), one of the most frequent lymphomas, was not performed to date.
METHODS
We examined the distribution of CB1 protein in primary cases of HL. Using
Endogenous and synthetic cannabinoids exert antiproliferative and proapoptotic effects in various types of cancer and in mantle cell lymphoma (MCL). In this study, we evaluated the expression of cannabinoid receptors type 1 and type 2 (CB1 and CB2) in non-Hodgkin lymphomas of B cell type (n = 62). A
We have earlier reported overexpression of the central and peripheral cannabinoid receptors CB1 and CB2 in mantle cell lymphoma (MCL), a B cell non-Hodgkin lymphoma. In this study, treatment with cannabinoid receptor ligands caused a decrease in viability of MCL cells, while control cells lacking
Mantle cell lymphoma (MCL) is a moderately aggressive B-cell lymphoma that responds poorly to currently used therapeutic protocols. In order to identify tumour characteristics that improve the understanding of biology of MCL, analysis of oligonucleotide microarrays were used to define specific gene
Endocannabinoids are lipid mediators thought to modulate central and peripheral neural functions. We report here gas chromatography-electron impact mass spectrometry analysis of human brain, showing that lipid extracts contain anandamide and 2-arachidonoylglycerol (2-AG), the most active
A novel [125I]-labelled photoaffinity ligand designed to detect cannabinoid binding sites has been used in mouse brain preparations and in cultured S49 mouse lymphoma cells. The ligand, 2-iodo-5'-azido-delta 8-THC, shows a high affinity for sites in both brain (Kd = 5.60 pM) and whole cell (Kd =
