Abstract:
Pregnane X receptor (PXR, NR1I2), a prototypical member of the nuclear receptor superfamily, has been implicated in various processes including metabolism, immune response, and inflammation. The immune system is made up of many interdependent parts, including lymphoid organs, cells, and cytokines, which play important roles in identifying, repelling, and eliminating pathogens and other foreign chemicals. An impaired immune system could contribute to various physical dysfunction, including severe infections, allergic diseases, autoimmune disorders, and other inflammatory diseases. Recent studies revealed the involvement of PXR in the pathogenesis of immune disorders and inflammatory responses. Thus, the aim of this work is to review and discuss the advances in research associated with PXR on immunity and inflammatory diseases and to provide insights into the development of therapeutic interventions of immune disorders and inflammatory diseases by targeting PXR.

Pregnane X receptor (PXR) influences immune responses and inflammation. Targeting PXR offers potential for treating immune and inflammatory diseases.
Area of Science:
- Molecular biology
- Immunology
- Pharmacology
Background:
- Pregnane X receptor (PXR) is a nuclear receptor involved in metabolism, immune response, and inflammation.
- The immune system protects against pathogens but dysfunction leads to diseases like infections, allergies, and autoimmune disorders.
- Emerging evidence links PXR to the development of immune and inflammatory conditions.
Purpose of the Study:
- To review current research on PXR's role in immunity and inflammation.
- To discuss PXR's involvement in the pathogenesis of immune and inflammatory diseases.
- To explore PXR as a therapeutic target for these conditions.
Main Methods:
- Literature review of recent studies on PXR, immunity, and inflammation.
- Analysis of PXR's mechanisms in immune regulation and inflammatory pathways.
- Synthesis of findings to identify therapeutic potential.
Main Results:
- PXR plays a significant role in modulating immune cell function and inflammatory signaling.
- Dysregulation of PXR contributes to the pathology of various immune and inflammatory diseases.
- PXR activation or inhibition shows promise in preclinical models of these disorders.
Conclusions:
- PXR is a critical regulator of immune and inflammatory processes.
- Targeting PXR presents a promising strategy for developing novel therapeutics for immune and inflammatory diseases.
- Further research is warranted to fully elucidate PXR's therapeutic potential.
