CD19-directed chimeric antigen receptor T-cell therapy: what can we learn from the haematologist?

CD19-directed chimeric antigen receptor (CAR) T-cell therapy, originally developed for haematological malignancies, has recently emerged as a promising therapy for patients with autoimmune diseases. By selectively depleting CD19-positive B-cells, this therapy brings a new approach in resetting immune dysregulation and potentially providing long-term remission for patients with a refractory disease. Recent reports have highlighted its effectiveness in conditions such as SLE, systemic sclerosis and myositis.

Targeting DOT1L and EZH2 synergizes in breaking the germinal center identity of Diffuse Large B-cell Lymphoma.

Differentiation of antigen-activated B cells into pro-proliferative germinal center (GC) B cells depends on the activity of the transcription factors MYC and BCL6, and the epigenetic writers DOT1L and EZH2. GCB-like Diffuse Large B Cell Lymphomas (GCB-DLBCLs) arise from GCB cells and closely resemble their cell of origin. Given the dependency of GCB cells on DOT1L and EZH2, we investigated the role of these epigenetic regulators in GCB-DLBCLs and observed that GCB-DLBCLs synergistically depend on the combined activity of DOT1L and EZH2.

Groundwater arsenic and antimony mobility from an antimony mining area: Controls of sulfide oxidation, carbonate and silicate weathering, and secondary mineral precipitation.

Sulfide mineral oxidation has been recognized as the key driver of arsenic (As) and antimony (Sb) mobility in mining-impacted groundwater. However, the role of carbonate and silicate weathering and secondary mineral precipitation in this process remain unknown. A comprehensive geochemical study of groundwater was conducted in an Sb-mining area, Hunan, China, with samples collected from aquifers of the Xikuangshan Formation (Dx), the Shetianqiao Formation (Ds ), and the Lower Carboniferous Formation (Cy).

Enteropathy-associated T-cell lymphoma: A population-based cohort study on incidence, treatment, and outcome in the Netherlands.

Introduction: Enteropathy-associated T-cell lymphoma (EATL) is a peripheral T-cell lymphoma (PTCL) with a poor prognosis. Cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with or without etoposide consolidated by autologous stem cell transplantation (ASCT) are recommended for fit PTCL patients. The role of etoposide and ASCT in EATL is unclear.
