Hodgkin and Reed-Sternberg (HRS) cells in classical Hodgkin Lymphoma (HL) are surrounded by a rich inflammatory infiltrate which aids in their survival and escape from cytotoxic CD8+ T cells (CTLs) and Natural Killer cells (NKs). Within HL environment, T regulatory cells (Tregs) directly suppress the activity of CTLs and NKs, enhancing the tolerance against HRS cells. B regulatory cells (Bregs) have been shown to support the differentiation of Tregs through IL-10 production; thus, we hypothesized that they could have a role in the pathophysiology of HL.

The identification of new molecular markers in Chronic Lymphocytic Leukemia (CLL) allowed to better define prognosis and clinical outcome. The actual staging systems could estimate the prognosis, but not the rapidity of disease evolution. Neither the identification of new molecular markers did allow to foresee the evolution and clinical response, because discordant findings were mostly reported. The aim of the present study was (1) to confirm the independent prognostic role of CD49d as a single marker in CLL patients, (2) to investigate the relationship between CD49d and other well-established CLL-membrane predictor markers (CD5, CD11c, CD20 and CD38) or clinical staging systems and (3) to evaluate the role of an immunophenotypic score based on the flow-cytometric detection of CD5, CD11c, CD20, CD38 and CD49d in the work up of CLL staging.

Cytomegalovirus (CMV) reactivation is one of the most frequent complication after hematopoietic stem cell transplantation (HSCT). Pre-transplant CMV-positive recipient serostatus is the most significant independent variable for viral reactivation.
