The Alkaline Response Pathway: Identification of a Novel Rim Pathway Activator


Microorganisms that cause human disease use various cues to determine when they encounter a host. One of these signals is the slightly alkaline pH of human tissues. We have defined components of a pH-responsive signaling pathway in the human fungal pathogen Cryptococcus neoformans. This particular signaling pathway is specific for fungi and important for the virulence of several plant and animal pathogens. We have identified a previously unknown protein that activates this pH-sensing pathway. This protein and its downstream signaling pathway play a major role in the interaction of this fungal pathogen and the host immune system.
