Thus, our findings show that the interaction between β-arrestins and PDZ proteins is key for CRFR1 trafficking and may be targeted to mitigate impaired CRFR1 signaling in mental and psychiatric disorders.
Thus, this study showed that alterations in CRHR1 gene were associated with higher levels of IL-1β, and increased risk for suicide, reinforcing the importance of multifactorial interactions of biological markers for psychiatric disorders.
More specifically, variants in the gene encoding the CRF(1) receptor interact with adverse environmental factors to predict risk for stress-related psychiatric disorders.
