C-di-GMP signaling in vector-borne pathogens. Repression of c-di-GMP-regulated extracellular matrix components in the mammalian host prevents host immune recognition and clearance, thus allowing disseminating systemic infection. Activation of c-di-GMP-regulated extracellular matrix components in the insect vector allows bacteria to survive the insect and infect additional mammalian hosts.
