Multi-Scale Modeling Recapitulates the Effect of Genetic Alterations Associated With Diffuse Large B-Cell Lymphoma in the Germinal Center Dynamics

چکیده
Diffuse large B-cell lymphoma is the most common subtype of non-Hodgkin’s lymphoma. It a germinal center (GC)–derived, aggressive, and heterogeneous disease. Several transcription factors signaling pathways that play central role in progression GC reaction differentiation have been shown to an oncogenic diffuse 6 (BCL6) transcriptional repressor induces phenotype blocks plasma cell (PC) differentiation, while interferon regulatory factor 4 (IRF4) B lymphocyte-induced maturation protein 1 (BLIMP1), promoter, both mediate PC exit from (1). Computational models are useful alternatives trial-and-error experimental investigation. Ordinary differential equation (ODE) used study different known mechanisms lymphomagenesis suggest candidate tumorigenic alterations (2). Furthermore, multi-scale (MSMs) cellular molecular involved tumor growth (3–6). In this study, we existing MSM simulate eight with several genetic BCL6-IRF4-BLIMP1 network lead deregulation could explain onset recapitulate dynamics observed such conditions. We loss BLIMP1 function (BLIMP BLIMP IRF inc ) result accumulation cells block thus correctly dynamics.

The Evaluation of Immunophenotypes in Diffuse Large B Cell Lymphoma: A Single Center Study
Background: Diffuse large B-cell lymphoma (DLBCL) is an aggressive malignancy of mature B lymphocytes. It is known as a heterogeneous disease with variable therapeutic responses and alternative therapies. Morphological and immunophenotypical evaluation of the biopsy specimens can help diagnose DLBCL. Methods: In the current study, 44 patients were chosen from Shaheed Sadoghi Hospital (2010&nda...

Primary Hepatic Lymphoma (PHL) is rare and possibly associated with viral hepatitis and autoimmune diseases. Scleroderma could exceptionally be complicated by lymphoma. We describe PHL occurring in a 52-year-old female suffering scleroderma for eight years, with no history of cytotoxic or high-dose glucocorticoid therapy. CT scan, performed to work-up abdominal discomfort, constipation, and ...
