Summary
Pannexins (Panx) are channel proteins found throughout the body, particularly in sensory organs. Research is exploring their roles in sensory perception and potential links to health and disease.
Area of Science:
- Molecular Biology
- Neuroscience
- Physiology
Background:
- Pannexins (Panx1, 2, 3) are integral membrane channel proteins in mammals.
- They share structural similarities with connexins, known gap junction proteins.
- Pannexin expression is widespread in vertebrates, including sensory organs.
Purpose of the Study:
- To review recent advances in understanding pannexin roles in sensory systems.
- To highlight the significance of pannexins in sensory perception.
- To address unresolved questions regarding pannexins in health and disease.
Main Methods:
- Review of cell-based studies on pannexin function.
- Analysis of data from genetically modified mice with pannexin ablation.
- Behavioral phenotyping in pannexin-deficient models.
Main Results:
- Pannexins are implicated in fundamental sensory perception functions.
- Their localization in sensory organs suggests critical roles.
- Genetic ablation models provide new insights into pannexin functions.
Conclusions:
- Pannexins are emerging as key players in sensory system physiology.
- Further research is needed to fully elucidate their roles in health and disease.
- Understanding pannexin function is crucial for addressing sensory-related conditions.

Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive...

GPCRs are primarily responsible for our sense of smell, taste, and vision. The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.

Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

8.1K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...
