Chronic lymphocytic leukemia (CLL) is a clinically heterogeneous disease characterized by the accumulation of a clonal population of B cells in peripheral blood, bone marrow, and lymphoid organs. More than 10 years ago, lipoprotein lipase (LPL) mRNA was identified as being strongly expressed in patients experiencing a more aggressive phenotype, while CLL patients with an indolent disease course lack expression of this marker. Since then, several reports confirmed the capability of LPL to predict CLL disease evolution at the moment of diagnosis.

- The B-cell receptor (BCR) plays a crucial role in how chronic lymphocytic leukaemia (CLL) cells interact with their surrounding environment, impacting disease progression and treatment resistance.
- Researchers aimed to establish a standard in vitro stimulation method to study how CLL BCR triggering affects cellular responses.
- Their findings showed that BCR stimulation significantly influenced gene and protein expression, with immobilised anti-IgM antibodies producing more consistent results than soluble ones, highlighting the importance of the stimulation method over genetic variations in BCR signaling.
Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western world and is characterized by a heterogeneous clinical course. This variability in clinical course has spiked the search for prognostic markers able to predict patient evolution at the moment of diagnosis. Markers demonstrated to be of value are the mutation status of the immunoglobulin heavy chain variable region genes (IGHV) and lipoprotein lipase (LPL) expression.

Poor prognosis is associated with expression of a B cell receptor (BCR) from unmutated immunoglobulin variable heavy-chain genes (IGHV) and expression of zeta-associated protein of 70 kDa (ZAP70).

Several prognostic factors such as the immunoglobulin heavy chain variable genes (IGHV) mutation status are linked to the B-cell receptor (BCR) complex, supporting a role for triggering the BCR in vivo in the pathogenesis. The miRNA profile upon stimulation and correlation with IGHV mutation status is however unknown.
