ABSTRACT A coordinated response to a complex and dynamic environment requires an organism to simultaneously monitor and interpret multiple signaling cues. In bacteria and some eukaryotes, environmental responses depend on the histidine autokinases (HKs). For example, VirA, a large integral membrane HK from Agrobacterium tumefaciens, regulates the expression of virulence genes in response to signals from multiple molecular classes (phenol, pH, and sugar). The ability of this pathogen to perceive inputs from different known host signals within a single protein receptor provides an opportunity to understand the mechanisms of signal integration. Here we exploited the conserved domain organization of the HKs and engineered chimeric kinases to explore the signaling mechanisms of phenol sensing and pH/sugar integration. Our data implicate a piston-assisted rotation of coiled coils for integration of multiple inputs and regulation of critical responses during pathogenesis.

ABSTRACTChemical signaling between cells is an effective way to coordinate behavior within a community. Although cell-to-cell signaling has mostly been studied in single species, it is now appreciated that the sensing of chemical signals across kingdoms can be an important regulator of nutrient acquisition, virulence, and host defense. In this review, we focus on the role of interkingdom signaling in the interactions that occur between bacterial pathogens and their mammalian hosts. We discuss the quorum-sensing (QS) systems and other mechanisms used by these bacteria to sense, respond to, and modulate host signals that include hormones, immune factors, and nutrients. We also describe cross talk between these signaling pathways and strategies used by the host to interfere with bacterial signaling, highlighting the complex bidirectional signaling networks that are established across kingdoms.

SUMMARYTrichobilharzia ocellatacercariae attach readily to the foot skin of their duck host, but poorly to preen-gland contents. The attachment to duck foot disappears when the skin surface lipids are extracted, and can be restored by reapplication of the lipids to the skin. Hydrophilic skin extracts are without any effect. Thin-layer chromatographic fractionation of duck-foot skin surface lipids reveals cholesterol and ceramides as attachment stimuli. A stimulation of cercarial attachment by these hydrophobic host signals is supported by the host identification pattern of the cercariae, which secures a close contact with encountered substrates.
