Overview of Gene Research
Gpr83, a class A G protein-coupled receptor, has been implicated in multiple physiological processes. It is considered a novel therapeutic target due to its roles in regulating feeding, reward, anxiety-related behaviors, and pain [1,2,3,4,5]. It has been suggested to be involved in the reward pathway, stress/anxiety responses, learning and memory, and metabolism in the brain, and its expression in the immune system is regulated by Foxp3 in T-regulatory cells [4].

Some studies used gene-knockdown models to explore Gpr83 function. Silencing Gpr83 expression in murine dorsal root ganglia (DRG) downregulated neuronal and behavioral nociception, and alleviated pathologic pain in hind paw inflammation and chemotherapy-induced peripheral neuropathy, suggesting its role in tuning peripheral pain sensitivity [2]. In anxiety-related behaviors, global knockdown of Gpr83 in male mice decreased such behaviors, while local knockdown in the basolateral amygdala of female mice led to more anxiety-related behaviors, indicating a region-and sex-dependent role of Gpr83 [5].

In conclusion, Gpr83 plays essential roles in regulating pain sensitivity and anxiety-related behaviors, as revealed by loss-of-function models. These findings contribute to understanding the underlying mechanisms of pain-related and anxiety-related disorders, potentially providing new therapeutic targets for these conditions.
