In this issue of Blood, Kreutzman and colleagues describe the existence of clonal cytotoxic T and NK cells in over 80% (15 of 18) of patients with CML at diagnosis which persisted during treatment with the tyrosine kinase inhibitors, imatinib and dasatinib.¹  Furthermore, they discovered that this clonal lymphocytosis expands further after therapy with dasatinib but not imatinib.

In this issue of Blood, Richardson et al report on a landmark treatment regimen for newly diagnosed myeloma patients that for the first time combines lenalidomide and bortezomib. This effort required a team approach comprising 2 competing pharmaceutical companies (joining forces to study this promising regimen) and multiple academic medical centers.¹ 

Warfarin and other vitamin K antagonists are very effective for the treatment and prevention of both arterial and venous thromboembolism. Recombinant factor VIIa may not be as effective as previously thought for the urgent reversal of warfarin.

In this issue of Blood, Pawlinski and colleagues identify myeloid cells and an unidentified nonhematopoietic cell(s) as the source of TF responsible for intravascular coagulation in a mouse model of endotoxemia, excluding a role for EC, VSMC, and platelet cell TF expression.¹
