Abstract
The innate immune system constitutes the first line of defense against infections and is also important for initiating the development of an adaptive immune response. The innate immune system recognizes microbial infection through germline-encoded pattern recognition receptors, which are responsible for decoding the microbial fingerprint and activating an appropriate response against the invading pathogen. In this review, we present and discuss current knowledge on how the innate immune system recognizes intracellular pathogens, activates intracellular signaling, induces gene expression, and orchestrates the microbicidal response against pathogens with a habitat within host cells.
