Peripheral Mechanisms of Itch
Current Problems in Dermatology
|September 1, 2016
Summary
Itch arises from environmental and internal factors activating skin nerve endings. Understanding these itch stimuli and receptors is key to developing revolutionary new therapies.
Area of Science:
- Dermatology
- Neuroscience
- Immunology
Background:
- The skin is constantly exposed to external and internal factors that can trigger itch.
- These stimuli activate specialized sensory nerve endings called pruriceptors.
- The itch signal travels from the skin to the brain for processing.
Purpose of the Study:
- To explore the diverse sources of itch stimuli.
- To identify the receptors involved in itch sensation.
- To provide a basis for developing novel anti-itch therapies.
Main Methods:
- Review of scientific literature on itch mechanisms.
- Analysis of exogenous and endogenous factors causing itch.
- Discussion of sensory nerve pathways involved in itch transmission.
Main Results:
- Identified environmental factors like allergens and microbiome substances as itch triggers.
- Highlighted endogenous mediators from skin cells and immune cells that activate pruriceptors.
- Described the neural pathways from skin to the central nervous system.
Conclusions:
- A comprehensive understanding of itch stimuli and receptors is crucial.
- Targeting peripheral itch mechanisms offers promising therapeutic avenues.
- Drug development targeting these pathways is revolutionizing itch treatment.

01:16Sensory Functions of the Skin
9.1K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

01:43Thermosensation
34.7K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

01:33Somatosensation
44.7K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

01:44Nociception
33.9K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

01:16Accessory Structures of the Skin: Hair and Hair Follicles
5.3K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

01:11Sensory Perception: Organization of the Somatosensory System
11.8K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...
