A device which converts a physical quantity into the proportional electrical signal is called a transducer. The Transducer mechanism • Most transmembrane signaling is accomplished by a small number of different molecular mechanisms (transducer mechanisms) • Large number of receptors share these handful of transducer mechanisms to generate an integrated and amplified response • Mainly 4 (four) major categories: 1. Central The circadian rhythm of autonomic function originates in the suprachiasmatic nucleus (SCN) in the hypothalamus, and is entrained by light falling on melanopsin-containing retinal ganglion cell dendrites (not rods or cones) in the eye and transmitted to the SCN Antithrombosis– seen with low-dose aspirin, for example There are many different types and classes of NSAID. NEIGRIHMS, Shillong. Dr. D. K. Brahma The tissue reacts by contracting/relaxing and an isometric or isotonic transducer is used to measure force or displacement, respectively. Generally speaking, a Transducer is a device that converts one form of energy into another by the principle of Transduction. Heterologous desensitization: Some times response to all agonists, which act through different receptors but produce the same overt effect, is decreased by exposure to any one of these agonists. This report further defines the mechanism of action of NKTR-214 by mathematically modeling the PK, the biased receptor occupancy, and the sustained downstream intracellular signaling.
