Cell Signaling

An intricate illustration of neurons, depicted in light blue against a dark blue background, highlighting the complex communication system of the brain with branching dendrites and interconnected neuron bodies.

Cell signaling refers mechanism of communication between cells within organisms driven by mechanical signals, such as touch, or chemical signals, such as hormones, growth factors, and neurotransmitters. In signaling pathways, stimuli are transmitted via a cascade process to yield the correct and appropriate response. Examples of cell signaling pathways include lipid signaling, insulin signaling, stress signaling, growth signaling, TOR signaling, and checkpoint signaling. Research in this field frequently covers studying and modeling cellular dynamics, analyzing cell signaling heterogeneity, crossover between cell signaling and other biological processes, and systematic studies of signaling dynamics.
