(Submitter supplied) Chronic lymphocytic leukemia (CLL) is characterized by the accumulation of CD5+ B lymphocytes in peripheral blood, lymphoid organs and BM. The main feature of the disease is accumulation of the malignant cells due to decreased apoptosis. CD84 belongs to the Signaling Lymphocyte Activating Molecule (SLAM) family of immunoreceptors, and has an unknown function in CLL cells. Here, we show that the expression of CD84 is significantly elevated from the early stages of the disease, and is regulated by macrophage migration inhibitory factor (MIF) and its receptor, CD74. more...

(Submitter supplied) Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare CD84 activated to control treated primary human M-MDSCs from multiple myeloma patients transcriptome profiling (RNA-seq) to understand the role of CD84 on these cells Methods: mRNA profiles from sorted M-MDSCs from patient bone marrow samples were generated by deep sequencing, in triplicate, using a bulk adaptation of the MARS-Seq protocol.

(Submitter supplied) Bendamustine is a commonly-used drug to treat CLL patients. Because drug-responses among the patients are heterogeneous, we wanted to find candidate genes to predict sensitivity to the compound We used microarrays to find genes whose expression correlates with the in vitro induced-cytotoxcity by a 24-hour incubation with bendamustine 25 µm

(Submitter supplied) Protective interactions with bystander cells in micro-environmental niches such as lymph nodes (LNs) contribute to survival and therapy resistance of chronic lymphocytic leukemia (CLL) cells. This is caused by a shift in expression of BCL-2 family members. Pro-survival proteins BCL-XL, BFL-1, and MCL-1 are upregulated by LN-residing T cells through CD40L interaction, presumably via NF-κB signaling. Macrophages also reside in the LN, and are assumed to provide important supportive functions for CLL cells. However, if and how macrophages are able to induce survival is incompletely known. We first established that macrophages induced survival due to an exclusive upregulation of MCL-1. Next, we investigated the mechanism underlying MCL-1 induction by macrophages in comparison with CD40L. Genome-wide expression profiling of in vitro macrophage- and CD40L-stimulated CLL cells indicated activation of the PI3K-AKT-mTOR pathway, which was confirmed in ex vivo CLL LN material. Inhibition of PI3K-AKT-mTOR signaling abrogated MCL-1 upregulation and survival by macrophages as well asCD40 stimulation. MCL-1 can be regulated at multiple levels, and we established that AKT leads to increased MCL-1 translation, but does not affect MCL-1 transcription or protein stabilization. Furthermore, among macrophage-secreted factors that could activate AKT, we found that induction of MCL-1 and survival critically depended on C-C Motif Chemokine Receptor-1 (CCR1). In conclusion, this study indicates that two distinct micro-environmental factors, CD40L and macrophages, signal via CCR1 to induce AKT activation resulting in translational stabilization of MCL-1, and hence can contribute to CLL cell survival.

(Submitter supplied) CD74 (invariant chain), expressed on B cells, is directly involved in shaping the B cell repertoire by regulating their survival in health and disease. Binding of its ligand, macrophage migration inhibitory factor (MIF), induces a cascade that results in CD74 intramembrane proteolysis, and the release of the CD74 intracellular domain (CD74-ICD). CD74-ICD translocates to the nucleus where it induces activation of transcription. more...
