The frequency of TP53 gene defects differs between chronic lymphocytic leukaemia subgroups harbouring distinct antigen receptors

In chronic lymphocytic leukaemia (CLL) tumour initiation and progression are linked to the interplay between cellextrinsic and cell-intrinsic mechanisms. Cell-extrinsic mechanisms relate to the crosstalk of CLL cells with their microenvironment through various receptors, including the B-cell receptor (BcR).
