Regulating the Regulators [PDF]
Science, 2003 Activation of the immune system in response to pathogens carries with it the possibility of a harmful autoimmune response. In their Perspective, Powrie and Maloy discuss a newly recognized group of regulatory T cells (T) that fine tune protective antimicrobial immune responses in order to minimize harmful immune pathology ( Hori et ...

CK2 and PML: Regulating the Regulator [PDF]
Cell, 2006 The PML protein induces senescence, and, upon oncogenic stress, its absence promotes cellular transformation. In this issue of Cell, Scaglioni et al. (2006) show that phosphorylation of PML by CK2, a kinase frequently activated in human cancers, promotes PML degradation.
