emisormensajereceptor

Emisormensajereceptor is a term used in some discussions of intercellular signaling to describe the integrated triad of emitter, messenger, and receptor. The word combines emisor (emitter), mensajero (messenger), and receptor, emphasizing that effective communication between cells depends on all three components working in concert. It is not a universally adopted term in mainstream literature, but it appears in pedagogical or theoretical contexts to highlight the dependencies within signaling pathways.

In this framework, the emitter is the cell that produces and releases the signaling molecule. The messenger is the chemical signal itself, such as a hormone, neurotransmitter, or cytokine, whose properties—stability, diffusion, concentration—shape how far and how strongly the message travels. The receptor is the molecular target on the responding cell that binds the messenger with specificity, triggering intracellular signaling cascades and, ultimately, a physiological response. The triad thus covers endocrine, paracrine, autocrine, and synaptic modes of communication, with the emitter’s location and timing, the messenger’s kinetics, and the receptor’s affinity and downstream pathways jointly determining the outcome.

The emisormensajereceptor concept supports systems-level thinking and can aid in modeling signaling networks, teaching, and comparative studies of different communication modalities. It serves as a reminder that signaling specificity arises from the coordinated properties of all three components rather than from any single element in isolation.
