TLR4 and acute lymphoblastic leukemia: I would like to understand better this point, in lines 245 and 245 the authors state that “Crossing Tlr4loxTB mice with Zp3-Cre mice produced mice in which expression of endogenous Tlr4 was globally reactivated in all cells.” Is this in ALL cells of the body, even in those where no TLR4 is normally expressed?
