Behavioral studies have shown that inhibition of the parabrachial nucleus can also reduce itch-scratching behavior.

Adeno-associated virus expression in the experimental group and the control group injected into the parabrachial nucleus.

Pharmacogenetic inhibition of the effect of the parabrachial nucleus on itch-induced scratching behavior.

This work reveals for the first time a long-range neural circuit that transmits itch information from the spinal cord to the brain, proves that the parabrachial nucleus is a key node in the itch information processing circuit, and further clarifies the important role of this brain region in chronic itch and allergic itch. This study lays a foundation for in-depth analysis of how itch information is processed in the brain, and provides a new direction for finding potential targets. <>
