Article Synopsis
  • The study investigates the distinct regions of the germinal center (GC)—the dark zone (DZ) and light zone (LZ)—which are crucial for B-cell expansion and antibody maturation, yet lack a clear understanding of their immune composition differences.
  • Researchers discovered specific DNA damage responses and chromatin features that explain why T-cells are excluded from the DZ region, providing insights into its immune-repulsive characteristics.
  • The findings highlight the role of the ATR kinase in regulating responses in the DZ, suggesting that targeting ATR could enhance immunotherapy effectiveness for aggressive types of lymphoma like Diffuse Large B-cell Lymphomas (DLBCL).

Unlabelled: Cyclic fasting-mimicking diet (FMD) is an experimental nutritional intervention with potent antitumor activity in preclinical models of solid malignancies. FMD cycles are also safe and active metabolically and immunologically in cancer patients. Here, we reported on the outcome of FMD cycles in two patients with chronic lymphocytic leukemia (CLL) and investigated the effects of fasting and FMD cycles in preclinical CLL models.

Evaluation of B-cell clonality can be challenging in the interpretation of lymphoid infiltrates on tissue sections. Clonality testing based on IG gene rearrangements analysis by PCR (IG-PCR) is the gold standard. Alternatively, B-cell clonality can be assessed by the recognition of immunoglobulin light chain (IgLC) restriction, by immunohistochemistry (IHC), chromogenic in situ hybridization (ISH) or flow cytometry (FC).

Unlabelled: Enhancers are noncoding regulatory DNA regions that modulate the transcription of target genes, often over large distances along with the genomic sequence. Enhancer alterations have been associated with various pathological conditions, including cancer. However, the identification and characterization of somatic mutations in noncoding regulatory regions with a functional effect on tumorigenesis and prognosis remain a major challenge.
