AI Article Synopsis
- Nodal marginal zone lymphoma (NMZL) is a rare subtype of non-Hodgkin lymphoma, making up about 2% of cases in both children and adults, often considered to be a mild disease but can be aggressive in adults.
- A 31-month-old boy with refractory EBV-positive NMZL experienced extensive disease that did not respond to initial chemotherapy or Rituximab, prompting treatment with second-line chemotherapy and an allogeneic hematopoietic stem cell transplant (HSCT).
- This case is significant as it is the first reported instance of a pediatric patient with refractory NMZL successfully treated with allogeneic stem cell transplant, indicating potential new treatment options for similar cases.
Article Abstract
Background: Nodal marginal zone lymphoma (NMZL) is a rare form of non-Hodgkin lymphoma (NHL), accounting for around 2% of all NHL in pediatrics and adults. It is considered the least common subtype of marginal zone lymphoma, which is rarely seen in pediatrics and is usually viewed as a mild disease. In adults, its presentation varies from mild to aggressive disease with multiple lymph node enlargement and systemic symptoms.
Case Report: Here, we report an interesting case of a 31-month-old boy who developed refractory EBV-positive NMZL with extensive disease. The tumor did not respond well to conventional chemotherapy and Rituximab. Therefore, we manage the disease with second-line chemotherapy, including bortezomib, followed by an allogeneic hematopoietic stem cell transplant (HSCT) with an excellent outcome.
Conclusion: Very few cases have been reported for aggressive NMZL children. The tumor was refractory to first line chemotherapy. However, the successful outcome was achieved by allogeneic stem cell transplant with myeloablative conditioning chemotherapy. The significance of this particular case is that this is the first reported case from pediatrics for refractory NMZL, which responded well to allogeneic stem cell transplant.

Objective: This study aims to explore the potential role of mesenchymal stem cells (MSCs) in the treatment of osteoarthritis (OA), particularly the function of the NOTCH1 signaling pathway in maintaining the stemness of MSCs and in chondrocyte differentiation.
Methods: Utilizing diverse analytical techniques on an osteoarthritis dataset, we unveil distinct gene expression patterns and regulatory relationships, shedding light on potential mechanisms underlying the disease. Techniques used include the culture of MSCs, induction of differentiation into chondrocytes, establishment of stable cell lines, Western Blot, and immunofluorescence.

Background: Anti-CD19 chimeric antigen receptor (CAR) T cell therapy is a common, yet highly efficient, cellular immunotherapy for lymphoma. However, many recent studies have reported on its cardiovascular (CV) toxicity. This study analyzes the cardiotoxicity of CD19 CAR T cell therapy in the treatment of lymphoma for providing a more valuable reference for clinicians.

Background: Sequential CD19 and CD22 chimeric antigen receptor (CAR)-T cell therapy offers a promising approach to antigen-loss relapse in relapsed/refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL); however, research in adults remains limited.
Methods: This study aimed to evaluate the efficacy and safety of sequential CD19 and CD22 CAR-T cell therapy in adult patients with R/R B-ALL between November 2020 and November 2023 (ChiCTR2100053871). Key endpoints included the adverse event incidence, overall survival (OS), and leukemia-free survival (LFS).

Background: Glioblastoma multiforme (GBM) exhibits a cellular hierarchy with a subpopulation of stem-like cells known as glioblastoma stem cells (GSCs) that drive tumor growth and contribute to treatment resistance. NAD(H) emerges as a crucial factor influencing GSC maintenance through its involvement in diverse biological processes, including mitochondrial fitness and DNA damage repair. However, how GSCs leverage metabolic adaptation to obtain survival advantage remains elusive.
