Historically, these systems were long considered as compartments that performed separate and different functions. However, a breakthrough occurred when advances in genetics and cellular and molecular biology techniques revealed that these systems shared molecular entities (such as cytokines, hormones and neurotransmitters) with their cognate receptors.
These molecular links between the three systems broaden our understanding of the regulation of physiological processes. This approach has generated a multiplicity of new concepts, including crosstalk between organs, axis, feedback, molecular sensors, protein multi-functionality, positive and negative signaling ratios and pathways (such as cell signaling, metabolism and stem cell differentiation, to name a few).
The improvement of experimental approaches has often resulted in major discoveries. This, combined with clear reasoning, intuition and coherence gave rise to new and unexpected concepts, and sometimes evolving ones. These new concepts lead the reader to the incredible transformation of biology in recent years.
