The study investigates the role of CD8+CD226+ T cells in chronic lymphocytic leukemia (CLL) and finds that these polyfunctional effector T cells are significantly diminished in patients with advanced disease stages and poor prognosis. The reduction of these cells is associated with elevated levels of IL-6 and MIP-1β, which may contribute to T cell dysfunction, suggesting that targeting these cytokines could be a potential immunotherapy strategy.

The research discusses the importance of various prognostic factors in chronic lymphocytic leukemia (CLL) for personalized therapy, highlighting the roles of TP53 status, karyotype, and IGHV mutational status in treatment outcomes with BCL2 inhibitors and BTK inhibitors. It notes that while BCL2 inhibitors are influenced by these factors, BTK inhibitors show different dependencies, particularly regarding resistance mechanisms and T-cell fitness in CAR-T therapy responses.

This review focuses on patients with chronic lymphocytic leukaemia (CLL) who have a complex karyotype, a group associated with poor prognosis and limited treatment options. It discusses the molecular characteristics, diagnostic methods, treatment strategies, and emerging therapies, emphasizing personalized management approaches to enhance clinical outcomes for these patients.

The research explores the genetic aberrations and signaling pathways involved in chronic lymphocytic leukemia (CLL), highlighting the shift from traditional predictive markers to a focus on resistance genes due to advancements in targeted therapies. Despite improved treatment outcomes, some patients still face relapse due to the disease’s heterogeneity and complex resistance mechanisms. The review emphasizes the importance of B-cell receptor signaling in CLL progression and advocates for personalized treatment strategies based on molecular profiling.
