Speaking the host language: how effector proteins manipulate the host.

injects over 40 virulence factors, termed effectors, into host cells to subvert diverse host cellular processes. Of these 40 effectors, at least 25 have been described as mediating eukaryotic-like, biochemical post-translational modifications (PTMs) of host proteins, altering the outcome of infection. The downstream changes mediated by an effector's enzymatic activity range from highly specific to multifunctional, and altogether their combined action impacts the function of an impressive array of host cellular processes, including signal transduction, membrane trafficking, and both innate and adaptive immune responses.
