Roles of Multidrug Resistance Protein 4 in Microbial Infections and Inflammatory Diseases
1Department of Geriatrics, Renmin Hospital of Wuhan University, Wuhan, China.
Abstract:
Numerous studies have reported the emergence of antimicrobial resistance during the treatment of common infections. Multidrug resistance (MDR) leads to failure of antimicrobial treatment, prolonged illness, and increased morbidity and mortality. Overexpression of multidrug resistance proteins (MRPs) as drug efflux pumps are one of the main contributions of MDR, especially multidrug resistance protein 4 (MRP4/ABCC4) in the development of antimicrobial resistance. The molecular mechanism of antimicrobial resistance is still under investigation. Various intervention strategies have been developed for overcoming MDR, but the effect is limited. Suppression of MRP4 may be an attractive therapeutic approach for addressing drug resistance. However, there are few reports on the involvement of MRP4 in antimicrobial resistance and inflammatory diseases. In this review, we introduced the function and regulation of MRP4, and then summarized the roles of MRP4 in microbial infections and inflammatory diseases as well as polymorphisms in the gene encoding this transporter. Further studies should be conducted on drug therapy targeting MRP4 to improve the efficacy of antimicrobial therapy. This review can provide useful information on MRP4 for overcoming antimicrobial resistance and anti-inflammatory therapy.
Insights
Multidrug resistance proteins (MRPs), particularly MRP4, contribute to antimicrobial resistance. Targeting MRP4 could offer a new strategy for combating infections and inflammatory diseases.
Area of Science:
- Pharmacology
- Microbiology
- Immunology
Background:
- Antimicrobial resistance (AMR) is a growing global health threat, leading to treatment failures and increased mortality.
- Multidrug resistance proteins (MRPs), especially MRP4 (ABCC4), are implicated in the efflux of antimicrobial drugs, contributing to AMR.
- The precise mechanisms of MRP4's role in AMR and inflammatory conditions require further elucidation.
Purpose of the Study:
- To review the function, regulation, and involvement of MRP4 in microbial infections and inflammatory diseases.
- To highlight the potential of targeting MRP4 as a therapeutic strategy against AMR and inflammation.
- To discuss the impact of genetic polymorphisms in the MRP4 gene.
Main Methods:
- Literature review of studies on MRP4 function, regulation, and its role in disease.
- Synthesis of current knowledge on MRP4's involvement in antimicrobial resistance mechanisms.
- Analysis of research on MRP4 in the context of inflammatory diseases.
Main Results:
- MRP4 acts as a drug efflux pump, significantly contributing to multidrug resistance (MDR) in various infections.
- MRP4 plays a role in modulating inflammatory responses, suggesting a dual function in infection and immunity.
- Genetic variations in the MRP4 gene may influence individual susceptibility and treatment outcomes.
Conclusions:
- MRP4 is a critical factor in the development of antimicrobial resistance and influences inflammatory processes.
- Suppression of MRP4 presents a promising therapeutic avenue for enhancing antimicrobial efficacy and managing inflammatory diseases.
- Further research into MRP4-targeted therapies is warranted to combat MDR and inflammatory conditions effectively.
