Mantle cell lymphoma: from pathogenesis to treatment for 2024 and beyond.

Mantle cell lymphoma (MCL) is a rare B-cell non-Hodgkin lymphoma with multiple subtypes including classical mantle cell lymphoma (cMCL), the leukemic variant of mantle cell lymphoma (LV-MCL), and in situ mantle cell neoplasia (ISMCN). Their clinical presentations differ significantly and range from indolent to very aggressive. The defining genetic feature and chief oncogenic mechanism of MCL involves the t(11;14)(q13;q32) translocation, which results in a fusion of the gene that encodes cyclin D1 (CCND1) and the immunoglobulin heavy chain gene (IGH).

As the population of patients receiving CAR T therapies grows, the identification and management of associated rare toxicities become increasingly crucial. This study aims to identify safety signals associated with commercial anti-B-cell maturation antigen (BCMA) CAR T therapies using the Food and Drug Administration Adverse Event Reporting System (FAERS).

BET inhibition reforms the immune microenvironment and alleviates T cell dysfunction in chronic lymphocytic leukemia.

Redundant tumor microenvironment (TME) immunosuppressive mechanisms and epigenetic maintenance of terminal T cell exhaustion greatly hinder functional antitumor immune responses in chronic lymphocytic leukemia (CLL). Bromodomain and extraterminal (BET) proteins regulate key pathways contributing to CLL pathogenesis and TME interactions, including T cell function and differentiation. Herein, we report that blocking BET protein function alleviates immunosuppressive networks in the CLL TME and repairs inherent CLL T cell defects.

Novel Spirocyclic Dimer, SpiD3, Targets Chronic Lymphocytic Leukemia Survival Pathways with Potent Preclinical Effects.

Unlabelled: Chronic lymphocytic leukemia (CLL) cell survival and growth is fueled by the induction of B-cell receptor (BCR) signaling within the tumor microenvironment (TME) driving activation of NFκB signaling and the unfolded protein response (UPR). Malignant cells have higher basal levels of UPR posing a unique therapeutic window to combat CLL cell growth using pharmacologic agents that induce accumulation of misfolded proteins. Frontline CLL therapeutics that directly target BCR signaling such as Bruton tyrosine kinase (BTK) inhibitors (e.

Second primary malignancies after commercial CAR T-cell therapy: analysis of the FDA Adverse Events Reporting System.

Second primary malignancies were reported in 536 of 12 394 (4.3%) adverse event reports following chimeric antigen receptor T-cell therapies in the Food and Drug Administration Adverse Event Reporting System. Myeloid and T-cell neoplasms were disproportionately more frequently reported, warranting further follow-up.

Diagnostic, Pathologic, and Therapeutic Considerations for Primary CNS Lymphoma.

Primary CNS lymphoma (PCNSL) is a rare lymphoma representing 3% of CNS malignancies. The diagnosis is complicated by the unique risks associated with brain biopsy, and the treatment is similarly complicated by the restriction of effective therapeutics able to cross the blood-brain barrier. Currently, the majority of individuals diagnosed with this disease are immunocompetent although immune deficiency related to HIV or immunosuppressive therapy remains an important risk factor.

Magnetic molecules lose identity when connected to different combinations of magnetic metal electrodes in MTJ-based molecular spintronics devices (MTJMSD).

Understanding the magnetic molecules' interaction with different combinations of metal electrodes is vital to advancing the molecular spintronics field. This paper describes experimental and theoretical understanding showing how paramagnetic single-molecule magnet (SMM) catalyzes long-range effects on metal electrodes and, in that process, loses its basic magnetic properties. For the first time, our Monte Carlo simulations, verified for consistency with regards to experimental studies, discuss the properties of the whole device and a generic paramagnetic molecule analog (GPMA) connected to the combinations of ferromagnet-ferromagnet, ferromagnet-paramagnet, and ferromagnet-antiferromagnet metal electrodes.

ALK-positive anaplastic large cell lymphoma (ALCL) represents approximately 6-7% of the mature T-cell lymphomas. This subtype contains a translocation between the ALK gene on chromosome 2 and one of several other genes that together form an oncogene. The most frequent translocation is t(2;5) which combines ALK with NPM1.

Defining the Role of the Gut Microbiome in the Pathogenesis and Treatment of Lymphoid Malignancies.

The gut microbiome is increasingly being recognized as an important immunologic environment, with direct links to the host immune system. The scale of the gut microbiome's genomic repertoire extends the capacity of its host's genome by providing additional metabolic output, and the close communication between gut microbiota and mucosal immune cells provides a continued opportunity for immune education. The relationship between the gut microbiome and the host immune system has important implications for oncologic disease, including lymphoma, a malignancy derived from within the immune system itself.

Systemic Light Chain Amyloidosis, Version 2.2023, NCCN Clinical Practice Guidelines in Oncology.

Primary systemic light chain amyloidosis (SLCA) is characterized by production of light chains that get converted to amyloid fibrils with an affinity for visceral organs and causing organ dysfunction. The therapy for SLCA is directed to recovering the function of the affected organs by targeting the abnormal plasma cell clone and slowing deposition of amyloid fibrils. The NCCN Guidelines for SLCA provide recommendations for workup, diagnosis, and treatment of primary as well as previously treated SLCA.
