This update will focus on new developments which can impact the understanding and management of patients with DLCL. The latter disorder is mostly derived from B lymphocytes which can be further subdivided into those that originate from the germinal center versus those that arise from non-germinal center areas in the lymph node. The differences between these two types will be discussed. The management of several new entities that relate to DLCL such as 'double hit lymphoma' and so called borderline entities will also be featured. New entities such as breast implant associated anaplastic large cell lymphoma will be described.

In the past few years, three protein molecules-USP53, NPY2R, and DCTN1-AS1-have garnered significant attention in scientific research due to their potential implications in tumor development. Mass spectrometry and proteomics techniques were used to analyze the three-dimensional structure of these protein molecules and predict their active sites and functional domains. The effects of USP53, NPY2R and DCTN1-AS1 on biological behavior of tumor cells were studied by constructing gene knockout and overexpression cell models.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of lymphoma in adults, which characterized by a high degree of heterogeneity in terms of clinical presentation, molecular phenotype, and genetic features. However, approximately 30 %-40 % of patients are refractory to standard chemotherapy, and their prognosis is poor. The emergence of small-molecule inhibitors, such as Bruton's tyrosine kinase inhibitors (BTKi), has greatly improved the treatment of DLBCL; however, drug resistance associated with small-molecule inhibitors has greatly limited their clinical application.

Yes-associated protein (YAP), a focal point of current biological research, is involved in regulating various life processes. In this report, live-cell fluorescence resonance energy transfer (FRET) imaging was employed to unravel the YAP complexes in MCF-7 cells. Fluorescence imaging of living cells co-expressing CFP (cyan fluorescent protein)-YAP and YFP (yellow fluorescent protein)-LATS1 (large tumor suppressor 1) plasmids revealed that YAP promoted LATS1 oligomerization around mitochondria.

Functional cartilaginous tissues can potentially be engineered by bringing together numerous microtissues (µTs) and allowing them to fuse and re-organize into larger, structurally organized grafts. The maturation level of individual microtissues is known to influence their capacity to fuse, however its impact on the long-term development of the resulting tissue remains unclear. The first objective of this study was to investigate the influence of the maturation state of human bone-marrow mesenchymal stem/stromal cells (hBM-MSCSs) derived microtissues on their fusion capacity and the phenotype of the final engineered tissue.

The unexplained association between infection and autoimmune disease is strongest for hepatitis C virus-induced cryoglobulinemic vasculitis (HCV-cryovas). To analyze its origins, we traced the evolution of pathogenic rheumatoid factor (RF) autoantibodies in four HCV-cryovas patients by deep single-cell multi-omic analysis, revealing three sources of B cell somatic mutation converged to drive the accumulation of a large disease-causing clone. A method for quantifying low-affinity binding revealed recurring antibody variable domain combinations created by V(D)J recombination that bound self-immunoglobulin G (IgG) but not viral E2 antigen.
