Viral Targeting of a Central Node of Control in the Endothelium Promotes Kaposi’s Sarcoma

Kaposi’s sarcoma associated herpesvirus (KSHV) selectively targets and persists in the endothelium; the resulting EC reprogramming leads to marked inflammation and the formation of multiple polyclonal, angioproliferative Kaposi’s sarcoma (KS) tumours. I have recently reported that the viral oncoprotein, Kaposin B (KapB), is a key mediator of KSHV-induced EC reprogramming. KapB targets a newly described nodal signaling axis, linking the kinase mitogen-activated protein kinase-activated protein kinase 2 (MK2) to the small cytoskeletal regulatory GTPase, RhoA.
