Vomeronasal Organ: Pheromone Recognition with a Twist
Pheromones are detected by the vomeronasal organ using members of two receptor superfamilies: the V1Rs and V2Rs. New studies show that MHC class I molecules are co-expressed in particular combinations with specific V2Rs in the vomeronasal organ. The role of these MHC molecules is unknown, but they may be of considerable biological significance.
متن کاملPheromone transduction in the vomeronasal organ.
Single-cell physiology and cloning efforts have extended studies of the vomeronasal organ to cellular and molecular levels. Recent work has shown that transduction in the vomeronasal organ is probably mediated by signalling pathways distinct from those that mediate transduction in the main olfactory system. An advance in understanding transduction has come with the cloning from rat vomeronasal ...
متن کاملSexual dimorphism in the vomeronasal system of the rabbit.
Studies have shown that the vomeronasal system (VNS), an olfactory neural network that participates in the control of reproductive physiology and behavior, is sexually dimorphic in the rat. These works have also shown two main characteristics of brain sexual dimorphism: (a) dimorphism appears in neural networks related to reproduction and (b) it can present two morphological patterns: one in wh...
متن کاملCa2+ -calmodulin feedback mediates sensory adaptation and inhibits pheromone-sensitive ion channels in the vomeronasal organ.
The mammalian vomeronasal organ (VNO) mediates the regulation of social behaviors by complex chemical signals. These cues trigger transient elevations of intracellular Ca(2+) in vomeronasal sensory neurons (VSNs), but the functional role of such Ca(2+) elevations is unknown. We show that stimulus-induced Ca(2+) entry plays an essential role as a negative feedback regulator of VSN sensitivity. E...
متن کاملImaging Pheromone Sensing in a Mouse Vomeronasal Acute Tissue Slice Preparation
Peter Karlson and Martin Lüscher used the term pheromone for the first time in 1959 to describe chemicals used for intra-species communication. Pheromones are volatile or non-volatile short-lived molecules secreted and/or contained in biological fluids, such as urine, a liquid known to be a main source of pheromones. Pheromonal communication is implicated in a variety of key animal modalities s...
