Schematic representation of the expression of transmembrane adaptor proteins in B-cell lymphomas. Each horizontal row represents an individual patient. (A) The expression of 3 molecules in the spectrum of B-cell lymphomas is illustrated. The majority of the cases summarized in Table 3 are included, with the exception of a small number of samples for which it was not possible (for technical reasons) to evaluate all of these markers. (B) Expression of PAG in DLBCL according to cellular origin (GC derived or non-GC). Cases were assigned to these 2 categories on the basis of immunostaining for CD10, BCL-6, and MUM1 (IRF4) following the algorithm reported by Hans et al.²³
