B-cell activating factor (BAFF) plays important roles in a variety of lymphoid malignancies. Compared with healthy adults, patients with non-Hodgkin lymphoma had higher level of serum BAFF, and it corresponded with disease severity, response for therapy and clinical outcome. Latent membrane protein 1 (LMP1) encoded by Epstein-Barr virus (EBV) which is a known agent of nasal, extranodal NK/T cell lymphoma (ENKTCL) can switch the BAFF activating promoter leading to higher expression of BAFF in EBV-related tumor cells. However, the relationship between BAFF and ENKTCL has not been reported. Here we proposed a hypothesis that BAFF might play a regulatory role in ENKTCL development and maintenance. Our results showed that serum BAFF in ENKTCL patients was significantly higher than that in control group and negatively correlated with patients' survival. It may be a valuable prognostic factor and deserved further study.

SET domain bifurcated histone lysine methyltransferase 1 (SETDB1/ESET), a pivotal H3K9 methyltransferase, has been extensively studied since its discovery over two decades ago. SETDB1 plays critical roles in immune regulation, including B cell maturation, T-cell activity modulation, and endogenous retrovirus (ERV) silencing. While essential for normal immune cell function, SETDB1 overexpression in cancer cells disrupts immune responses by suppressing tumor immunogenicity and facilitating immune evasion.

In cancer, TLS are associated with better prognosis and enhanced response to immunotherapy, making these structures attractive therapeutic targets. However, the mechanisms regulating TLS formation and maintenance in cancer are incompletely understood.

The injectable contraceptive, depot medroxyprogesterone acetate (DMPA), is associated with compromised cervical mucosal barriers. High-resolution spatial transcriptomics is applied here to reveal the spatial localization of these altered molecular markers. Ectocervical tissue samples from Kenyan sex workers using DMPA, or non-hormonal contraceptives, underwent spatial transcriptomics and gene set enrichment analyses.

Objective: Both belimumab and telitacicept are recognised blockers for B lymphocyte activation, both of which have been approved as add-on therapies for SLE in China. The aim of this study is to compare the efficacy of rituximab (RTX) followed by belimumab or telitacicept in a real-world cohort.
Methods: A total of 49 refractory lupus nephritis patients were enrolled from four independent centres, subsequently categorised into two treatment groups: belimumab group (n=35) and telitacicept group (n=14) based on their treatment following RTX.
