Abstract

Mammalian cells behave as computers: they operate as information-processing systems that dynamically integrate and respond to diverse environmental signals. This is possible thank to a myriad of regulatory circuits consisting of sensitive elements that recognize and bind analytes, and of transducer modules that filter the signals and initiate a cellular response modulating theirs or the behavior of heterologous pathways.

Similarly, synthetic biology has prompted the design of sensors that are connected to precise actuation to either shed light on the behavior of regulatory networks or to implement novel cellular functionalities with diagnostic or therapeutic purposes.

Synthetic biosensors are based on the coupling of sensing and actuation modules that are finely balanced to obtain the desired modularity and specificity. Classically, sensors are defined based on the source of the signals detected: biosensors for environmental signals, biosensors for extracellular chemicals, and biosensors for intracellular chemicals and metabolites. Mammalian synthetic biosensors require further classification that relies on the type of activity involved in the signal-to-gene-activation cascade: transcriptional, posttranscriptional, and translational sensors. This chapter provides an overview of mammalian synthetic biology-based sensors and their architecture and connection to downstream signal processing.
