Abstract
Recent transcriptomic-based analysis of diffuse large B cell lymphoma (DLBCL) has highlighted the clinical relevance of LN fibroblast and tumor-infiltrating lymphocyte (TIL) signatures within the tumor microenvironment (TME). However, the immunomodulatory role of fibroblasts in lymphoma remains unclear. Here, by studying human and mouse DLBCL-LNs, we identified the presence of an aberrantly remodeled fibroblastic reticular cell (FRC) network expressing elevated fibroblast-activated protein (FAP). RNA-Seq analyses revealed that exposure to DLBCL reprogrammed key immunoregulatory pathways in FRCs, including a switch from homeostatic to inflammatory chemokine expression and elevated antigen-presentation molecules. Functional assays showed that DLBCL-activated FRCs (DLBCL-FRCs) hindered optimal TIL and chimeric antigen receptor (CAR) T cell migration. Moreover, DLBCL-FRCs inhibited CD8+ TIL cytotoxicity in an antigen-specific manner. Notably, the interrogation of patient LNs with imaging mass cytometry identified distinct environments differing in their CD8+ TIL-FRC composition and spatial organization that associated with survival outcomes. We further demonstrated the potential to target inhibitory FRCs to rejuvenate interacting TILs. Cotreating organotypic cultures with FAP-targeted immunostimulatory drugs and a bispecific antibody (glofitamab) augmented antilymphoma TIL cytotoxicity. Our study reveals an immunosuppressive role of FRCs in DLBCL, with implications for immune evasion, disease pathogenesis, and optimizing immunotherapy for patients.

Abstract
Extracellular vesicles (EVs) have emerged as important players in cell-to-cell communication within the bone marrow (BM) of multiple myeloma (MM) patients, where they mediate several tumor-associated processes. Here, we investigate the contribution of fibroblasts-derived EVs (FBEVs) in supporting BM angiogenesis. We demonstrate that FBEVs' cargo contains several angiogenic cytokines (i.e., VEGF, HGF, and ANG-1) that promote an early over-angiogenic effect independent from EVs uptake. Interestingly, co-culture of endothelial cells from MM patients (MMECs) with FBEVs for 1 or 6 h activates the VEGF/VEGFR2, HGF/HGFR, and ANG-1/Tie2 axis, as well as the mTORC2 and Wnt/β-catenin pathways, suggesting that the early over-angiogenic effect is a cytokine-mediated process. FBEVs internalization occurs after longer exposure of MMECs to FBEVs (24 h) and induces a late over-angiogenic effect by increasing MMECs migration, chemotaxis, metalloproteases release, and capillarogenesis. FBEVs uptake activates mTORC1, MAPK, SRC, and STAT pathways that promote the release of pro-angiogenic cytokines, further supporting the pro-angiogenic milieu. Overall, our results demonstrate that FBEVs foster MM angiogenesis through dual time-related uptake-independent and uptake-dependent mechanisms that activate different intracellular pathways and transcriptional programs, providing the rationale for designing novel anti-angiogenic strategies.

Abstract
Chemokine receptors and their ligands have been identified as playing an important role in the development of diffuse large B-cell lymphoma (DLBCL), follicular lymphoma, and Richter syndrome (RS). Our aim was to investigate the different expression profiles in de novo DLBCL, transformed follicular lymphoma (tFL), and RS. Here, we profiled the mRNA expression levels of 18 chemokine receptors (CCR1-CCR9, CXCR1-CXCR7, CX3CR1 and XCR1) using RQ-PCR, as well as immunohistochemistry of seven chemokine receptors (CCR1, CCR4-CCR8 and CXCR2) in RS, de novo DLBCL, and tFL biopsy-derived tissues. Tonsil-derived germinal center B-cells (GC-B) served as non-neoplastic controls. The chemokine receptor expression profiles of de novo DLBCL and tFL substantially differed from those of GC-B, with at least 5-fold higher expression of 15 out of the 18 investigated chemokine receptors (CCR1-CCR9, CXCR1, CXCR2, CXCR6, CXCR7, CX3CR1 and XCR1) in these lymphoma subtypes. Interestingly, the de novo DLBCL and tFL exhibited at least 22-fold higher expression of CCR1, CCR5, CCR8, and CXCR6 compared with RS, whereas no significant difference in chemokine receptor expression profile was detected when comparing de novo DLBCL with tFL. Furthermore, in de novo DLBCL and tFLs, a high expression of CCR7 was associated with a poor overall survival in our study cohort, as well as in an independent patient cohort. Our data indicate that the chemokine receptor expression profile of RS differs substantially from that of de novo DLBCL and tFL. Thus, these multiple dysregulated chemokine receptors could represent novel clinical markers as diagnostic and prognostic tools. Moreover, this study highlights the relevance of chemokine signaling crosstalk in the tumor microenvironment of aggressive lymphomas.

Abstract
Ion channels are pore-forming proteins that allow ions to flow across plasma membranes and intracellular organelles in both excitable and non-excitable cells. They are involved in the regulation of several biological processes (i.e., proliferation, cell volume and shape, differentiation, migration, and apoptosis). Recently, the aberrant expression of ion channels has emerged as an important step of malignant transformation, tumor progression, and drug resistance, leading to the idea of “onco-channelopathy”. Here, we review the contribution of ion channels and transporters in multiple myeloma (MM), a hematological neoplasia characterized by the expansion of tumor plasma cells (MM cells) in the bone marrow (BM). Deregulation of ion channels sustains MM progression by modulating intracellular pathways that promote MM cells’ survival, proliferation, and drug resistance. Finally, we focus on the promising role of ion channels as therapeutic targets for the treatment of MM patients in a combination strategy with currently used anti-MM drugs to improve their cytotoxic activity and reduce adverse effects.

Abstract
Simple Summary Multiple myeloma (MM) is an aggressive hematological neoplasia caused by the uncontrolled proliferation of aberrant plasmacells. Neoplastic transformation and progression are driven by a number of biological processes, called ‘hallmarks of cancer’, which are regulated by different molecules, including long non-coding RNAs. A deeper understanding of the mechanisms that regulate MM development and progression will help to improve patients stratification and management, and promote the identification of new therapeutic targets. Abstract Long non-coding RNAs (lncRNAs) are transcripts longer than 200 nucleotides that are not translated into proteins. Nowadays, lncRNAs are gaining importance as key regulators of gene expression and, consequently, of several biological functions in physiological and pathological conditions, including cancer. Here, we point out the role of lncRNAs in the pathogenesis of multiple myeloma (MM). We focus on their ability to regulate the biological processes identified as “hallmarks of cancer” that enable malignant cell transformation, early tumor onset and progression. The aberrant expression of lncRNAs in MM suggests their potential use as clinical biomarkers for diagnosis, patient stratification, and clinical management. Moreover, they represent ideal candidates for therapeutic targeting.

Abstract
Abstract
Tumor cells engage in bidirectional interactions with stroma and immune cells to promote disease progression and immune evasion. Stroma-specific gene signatures have been associated with outcome in diffuse large B-cell lymphoma (DLBCL), but their immunobiology has been understudied.
To characterize the stromal landscape in lymphoma, we performed high-dimensional imaging mass cytometry analysis of the major stroma subsets and revealed a marked expansion and remodeling of the immuno-specialized fibroblastic reticular cells (FRCs) in human DLBCL biopsies (n=53). The FRC network was similarly remodeled in tumors from the IμBcl6 transgenic model of lymphoma, and aberrant fibroblasts were in close proximity to cancer cells.
Modelling the interactions between murine and patient FRCs and tumor cells, using 2D and 3D cultures, showed that lymphoma drives the acquisition of an inflammatory-like, pro-tumoral (upregulation of fibroblast activating protein-α, FAP) phenotype and associated functional capabilities. Comparative bulk transcriptomic analysis revealed that lymphoma-FRCs undergo transcriptional reprogramming and activate gene pathways associated with inflammatory responses. Moreover, single-cell RNA-seq revealed an expansion of activated FRC clusters expressing B cell supporting genes, while T cell-associated FRCs were contracted. Altered chemokine signaling pathways in DLBCL-FRCs were functionally linked to reduced attraction of T cells and impeded migration along the lymphoma-reticular network. Moreover, lymphoma-FRCs upregulated expression of inhibitory PD-1 ligands that reduced the anti-tumor cytolytic activity of CD8+ T cells, a T cell bispecific antibody (CD20-TCB, glofitamab) and anti-CD19 CAR T cells in our coculture models.
To overcome the immunosuppressive activity of DLBCL-FRCs, we investigated the use of CD20-TCB in combination with stroma-targeting immunocytokine fusion protein drug (FAP-IL2v, RG7461) or costimulatory fusion protein (FAP-4-1BBL, RG7827). Functional cytotoxicity assays using human and murine primary DLBCL patient samples revealed that both stroma-targeting drugs paired effectively with the CD20-TCB to enhance the cytotoxic activity of autologous CD8+ T cells. In addition, the ability of immune-/stroma- targeted combination immunotherapy to trigger anti-tumor activity and CD8+ T cell retention within the FRC-TME was demonstrated using 3D precision-cut lymph node slice-based organotypic cultures of DLBCL and other B cell malignancies.
In conclusion our data reveal that lymphoma cells actively reprogram FRCs that acquire altered immunoregulatory function which prevents effective T cell motility and suppresses the anti-tumor function of cytolytic T cells. Importantly, we demonstrate that combination immunotherapy incorporating fibroblast-targeting fusion proteins could effectively recover anti-tumor T cell activity.

Abstract
High-dimensional cytometry is an innovative tool for immune monitoring in health and disease, and it has provided novel insight into the underlying biology as well as biomarkers for a variety of diseases. However, the analysis of large multiparametric datasets usually requires specialist computational knowledge. Here, we describe ImmunoCluster (https://github.com/kordastilab/ImmunoCluster), an R package for immune profiling cellular heterogeneity in high-dimensional liquid and imaging mass cytometry, and flow cytometry data, designed to facilitate computational analysis by a nonspecialist. The analysis framework implemented within ImmunoCluster is readily scalable to millions of cells and provides a variety of visualization and analytical approaches, as well as a rich array of plotting tools that can be tailored to users' needs. The protocol consists of three core computational stages: (1) data import and quality control; (2) dimensionality reduction and unsupervised clustering; and (3) annotation and differential testing, all contained within an R-based open-source framework.

Abstract
Cancers, including lymphomas, develop in complex tissue environments where malignant cells actively promote the creation of a pro-tumoral niche that suppresses effective anti-tumor effector T cell responses. Research is revealing that the tumor microenvironment (TME) differs between different types of lymphoma, covering inflamed environments, as exemplified by Hodgkin lymphoma, to non-inflamed TMEs as seen in chronic lymphocytic leukemia (CLL) or diffuse-large B-cell lymphoma (DLBCL). In this review we consider how T cells and interferon-driven inflammatory signaling contribute to the regulation of anti-tumor immune responses, as well as sensitivity to anti-PD-1 immune checkpoint blockade immunotherapy. We discuss tumor intrinsic and extrinsic mechanisms critical to anti-tumor immune responses, as well as sensitivity to immunotherapies, before adding an additional layer of complexity within the TME: the immunoregulatory role of non-hematopoietic stromal cells that co-evolve with tumors. Studying the intricate interactions between the immune-stroma lymphoma TME should help to design next-generation immunotherapies and combination treatment strategies to overcome complex TME-driven immune suppression.

Abstract
Cancer treatment has been transformed by checkpoint blockade therapies, with the highest anti-tumor activity of anti-programmed death 1 (PD-1) antibody therapy seen in Hodgkin lymphoma. Disappointingly, response rates have been low in the non-Hodgkin lymphomas, with no activity seen in relapsed/refractory chronic lymphocytic leukemia (CLL) with PD-1 blockade. Thus, identifying more powerful combination therapy is required for these patients. Here, we preclinically demonstrate enhanced anti-CLL activity following combinational therapy with anti-PD-1 or anti-PD-1 ligand (PD-L1) and avadomide, a cereblon E3 ligase modulator (CELMoD). Avadomide induced type I and II interferon (IFN) signaling in patient T cells, triggering a feedforward cascade of reinvigorated T-cell responses. Immune modeling assays demonstrated that avadomide stimulated T-cell activation, chemokine expression, motility and lytic synapses with CLL cells, as well as IFN-inducible feedback inhibition through upregulation of PD-L1. Patient-derived xenograft tumors treated with avadomide were converted to CD8+ T cell-inflamed tumor microenvironments that responded to anti-PD-L1/PD-1-based combination therapy. Notably, clinical analyses showed increased PD-L1 expression on T cells, as well as intratumoral expression of chemokine signaling genes in B-cell malignancy patients receiving avadomide-based therapy. These data illustrate the importance of overcoming a low inflammatory T-cell state to successfully sensitize CLL to checkpoint blockade-based combination therapy.

Abstract
Chronic lymphocytic leukemia (CLL) patients assigned to stereotyped subset #4 (mutated IGHV4-34/IGKV2-30 BCR Ig) display a particularly indolent disease course. Immunogenetic studies of the clonotypic BCR Ig of CLL subset #4 suggested a resemblance with B cells rendered anergic through chronic autoantigenic stimulation. In this article, we provide experimental evidence that subset #4 CLL cells show low IgG levels, constitutive ERK1/2 activation, and fail to either release intracellular Ca(2+) or activate MAPK signaling after BCR cross-linking, thus displaying a signature of B cell anergy at both biochemical and functional levels. Interestingly, TLR1/2 triggering restored BCR functionality, likely breaching the anergic state, and this was accompanied by induction of the miR-17∼92 cluster, whose members target critical BCR-associated molecules, including MAPKs. In conclusion, we demonstrate BCR anergy in CLL subset #4 and implicate TLR signaling and the miR-17∼92 cluster in the regulation of the anergic state. This detailed signaling profiling of subset #4 has implications for advanced understanding of the complex regulation of intracellular signaling pathways in CLL, currently a major therapeutic target of the disease.

Abstract
Immortalized cell lines representative of chronic lymphocytic leukemia (CLL) can assist in understanding disease pathogenesis and testing new therapeutic agents. At present, very few representative cell lines are available. We here describe the characterization of a new cell line (PCL12) that grew spontaneously from the peripheral blood (PB) of a CLL patient with progressive disease and EBV infection. The CLL cell origin of PCL12 was confirmed after the alignment of its IGH sequence against the “original” clonotypic sequence. The IGH gene rearrangement was truly unmutated and no CLL-related cytogenetic or genetic lesions were detected. PCL12 cells express CD19, CD20, CD5, CD23, low levels of IgM and IgD and the poor-outcome-associated prognostic markers CD38, ZAP70 and TCL1. In accordance with its aggressive phenotype the cell line is inactive in terms of LYN and HS1 phosphorylation. BcR signalling pathway is constitutively active and anergic in terms of p-ERK and Calcium flux response to α-IgM stimulation. PCL12 cells strongly migrate in vitro in response to SDF-1 and form clusters. Finally, they grow rapidly and localize in all lymphoid organs when xenotrasplanted in Rag2-/-γc-/- mice. PCL12 represents a suitable preclinical model for testing pharmacological agents.

Abstract
The identification of molecules involved in tumor initiation and progression is fundamental for understanding disease's biology and, as a consequence, for the clinical management of patients. In the present work we will describe an optimized proteomic approach for the identification of molecules involved in the progression of Chronic Lymphocytic Leukemia (CLL). In detail, leukemic cell lysates are resolved by 2-dimensional Electrophoresis (2DE) and visualized as "spots" on the 2DE gels. Comparative analysis of proteomic maps allows the identification of differentially expressed proteins (in terms of abundance and post-translational modifications) that are picked, isolated and identified by Mass Spectrometry (MS). The biological function of the identified candidates can be tested by different assays (i.e. migration, adhesion and F-actin polymerization), that we have optimized for primary leukemic cells.

Abstract
The sialic-acid-binding immunoglobulin-like lectin SIGLEC-G is a negative regulator of B-cell receptor-mediated calcium signaling. Its deficiency leads to reduced turnover and increased proliferation and survival of murine B-1a cells. Siglecg(-/-) mice show a premature expansion of polyclonal CD5(+) B cells in the spleen and the peritoneal cavity. Here we studied the fate of B lymphocytes in Siglecg(-/-) mice over time. We demonstrate that in aging animals SIGLEC-G deficiency promotes progressive accumulation of monoclonal B lymphocytes and increases the susceptibility to develop B-cell lymphoproliferative disorders. Lymphoid tumors arising in aged Siglecg(-/-) mice are monoclonal and histologically heterogeneous as they include diffuse large B-cell lymphoma, follicular lymphoma, and medium-to-large B-cell monomorphic lymphoma but surprisingly not chronic lymphocytic leukemia. The tumors express high levels of BCL-2 and are transplantable. In keeping with these findings we have also observed a remarkable down-regulation of the human ortholog SIGLEC10 in human B-cell lymphoma and leukemia cell lines. Taken together, these observations indicate that the down-regulation of negative B-cell receptor regulators such as SIGLEC-G/SIGLEC10 may represent another mechanism relevant to the pathogenesis of B-cell lymphomas.

Abstract
PURPOSE The emerging role of Toll-like receptors (TLR) in the pathogenesis of chronic lymphocytic leukemia (CLL) led us to ask whether TLR stimulation may protect CLL cells from drug-induced apoptosis. EXPERIMENTAL DESIGN We cultured in vitro malignant B cells freshly isolated from 44 patients with CLLs in the presence or the absence of different concentrations of fludarabine before or after 24-hour TLR stimulation with specific ligands and evaluated cell viability, apoptosis, and molecular pathways involved. RESULTS Heterogeneity was observed among samples. In leukemic cells from patients bearing adverse prognostic factors, TLR stimulation caused a significant increase of protection to fludarabine treatment, whereas this did not occur in the cells from patients with good prognosis. To identify novel molecular mechanisms accounting for the dichotomy of response between the two groups of patients, we conducted an apoptosis gene expression profile on leukemic cells either unstimulated or stimulated with TLR9 ligand. Strikingly, TLR9 stimulation specifically upregulated the expression of lymphotoxin-α in cells where an increased protection to fludarabine treatment was observed. Also, the expression of miR-155-3p was significantly increased after stimulation of distinct TLR in cells where fludarabine treatment was less effective. CONCLUSIONS These results suggest that at least in a proportion of patients, in vitro sensitivity to fludarabine may be modulated by the stimulation of TLR, likely mimicking microenvironmental signals occurring in vivo.

Abstract
Monoclonal B lymphocytosis (MBL) is a frequent phenomenon in the general population. Despite a phenotype similar to chronic lymphocytic leukemia (CLL), the possibility exists that most cases are not necessarily a pre-leukemic condition. This is suggested by the fact that MBL is at least 100 times more frequent than CLL and the diagnosis of CLL is not an inevitable fate, even among MBL cases with lymphocytosis, where it occurs only in 1.1% of the cases per year. The high incidence of MBL, if coupled with the possibility of evolution into a frank leukemic state, poses evident clinical and health system concerns. MBL in the general population usually accounts for a very low number of all circulating B-cells, being <10% of all B lymphocytes. This creates the need for a better characterisation of MBL at molecular level, aiming to identify biological features that may define which cases are more likely to progress towards clinically overt CLL. This approach should also help to avoid unnecessary and prolonged follow-ups in all individuals carrying MBL, excluding those who are extremely unlikely to develop CLL.
