receptorons
Receptorons are a hypothetical class of signaling entities proposed in theoretical discussions of receptor biology. They are described as particles or molecules capable of interacting with cellular receptors to modulate signal transduction. In speculative models, receptorons may act as ligands that bind extracellular receptors, as intracellular modulators that influence receptor conformation from within the cell, or as transmembrane agents that alter receptor sensitivity.
Classification commonly imagined includes three rough categories: Type I receptorons are diffusible extracellular ligands that target
Although no experimental evidence currently confirms their existence, receptorons are discussed in some theoretical frameworks as
The term remains controversial and is not part of standard pharmacology or cell biology nomenclature. If validated,
