The effectiveness of therapy combining dihydroartemisinin (DHA) and small interfering RNA targeting Notch1 (siNotch1) in T-cell lymphoma remains unknown. The present study explored the potential and possible mechanisms of combined dihydroarteminin, and siNotch1 therapy for T-cell lymphoma. It was demonstrated that the viability rates of siRNA-DHA-treated cells was significantly suppressed in comparison with those in control cells, control siRNA cells, siRNA-treated cells and DHA-treated cells (P<0.01). Additionally, there was a significant increase in cell apoptosis of siRNA-DHA-treated cells in comparison with those of control cells, control siRNA cells, siRNA-treated cells, DHA-treated cells (P<0.05). Furthermore, Notch1 and c-Myc mRNA and protein expression were decreased in siRNA-DHA-treated cells (P<0.05). The present study demonstrated that DHA combined with siNotch1 is able to suppress proliferation and promote apoptosis, and downregulate the expression of Notch1 and c-Myc mRNA and protein in T-cell lymphoma cells. Targeting Notch1/c-Myc signaling with siRNA and DHA may represent a novel strategy for treating human T-cell lymphoma.

Systemic hydroa vacciniforme lymphoproliferative disorder in a patient with chronic active EBV infection.

Hydroa vacciniforme lymphoproliferative disorders (HVLPD) fall within the clinical spectrum of chronic active epstein barr virus (EBV) disease (CAEBVD), ranging from localised and/or indolent forms (classic HVLPD) to systemic disease with fever, hepatosplenomegaly and lymphadenopathy (systemic HVLPD). A preadolescent male with 47XYY, multicystic dysplastic kidney, autism spectrum disorder and Attention-deficit/hyperactivity disorder (ADHD) presented with photodistributed non-pruritic, non-painful necrotic papulovesicles accompanied by non-febrile intermittent fatigue and lymphadenopathy. The patient had a history of EBV pneumonia in infancy confirmed by CT scan and was later diagnosed with CAEBV.

B cell immunity carries the inherent risk of deviating into autoimmunity and malignancy, which are both strongly associated with genetic variants or alterations that increase immune signaling. Here, we investigated the interplay of autoimmunity and lymphoma risk factors centered around the archetypal negative immune regulator TNFAIP3/A20 in mice. Counterintuitively, B cells with moderately elevated sensitivity to stimulation caused fatal autoimmune pathology, while those with high sensitivity did not.

Purpose: This study aims to comprehensively characterize the clinical, demographic, and histopathological features of ocular adnexal lymphoma (OAL) and assess their impact on patients' survival outcomes.
Methods: A total of 123 patients were included in the study; of these, 93 patients were selected for survival analysis. Survival data were analyzed using the Kaplan-Meier test, and correlation was assessed through the log-rank test and Cox regression analysis.

: The primary objective of this study was to investigate clinical manifestations, time to diagnosis, and number of biopsies in patients with extranodal natural killer T-cell lymphoma (ENKTL). The secondary objectives were to determine response rates, survival outcomes, prognostic factor for overall survival (OS), and validation of the Prognostic Index of Natural Killer Lymphoma (PINK), Ann Arbor staging system (AASS), and the CA system. : This retrospective study included data pertaining to patients with newly diagnosed ENKTL in Chiang-Mai University Hospital from 2004 to 2020.

Background: Single antigen (Ag)-targeted immunotherapies for acute lymphoblastic leukemia (ALL) are highly effective; however, up to 50% of patients relapse after these treatments. Most of these relapses lack target Ag expression, suggesting targeting multiple Ags would be advantageous.
Materials & Methods: The multi-Ag immune responses to ALL induced by transducing cell lines with xenoAgs green fluorescent protein and firefly luciferase was elucidated using flow cytometry, ELISA, and ELISpot assays.
