Genetics of SLE: evidence from mouse models

Area of Science:

• Genetics
• Immunology
• Systemic Lupus Erythematosus (SLE)

Background:

• Mouse models have historically been vital for studying the genetic basis of lupus.
• Recent advances include genome-wide association studies in humans and gene identification in lupus-prone mice.
• There is a growing understanding of the interdependence between mouse and human lupus genetics.

Purpose of the Study:

• To review the progress in lupus genetics.
• To emphasize the continued importance of mouse models in SLE research.
• To highlight the convergence of genetic pathways in human and murine lupus.

Main Methods:

• Review of genome-wide association studies in humans.
• Identification of susceptibility genes in mouse models.
• Comparative analysis of genetic pathways in human and murine lupus.

Main Results:

• Genome-wide association studies have identified numerous human lupus susceptibility genes.
• Specific genes like Fcgr2b, Ly108, Kallikrein, and Coronin-1A are implicated in both human and mouse lupus.
• Functional pathways affected in lupus show significant overlap between humans and mice.

Conclusions:

• Mouse models remain indispensable for unraveling the genetic architecture of systemic lupus erythematosus (SLE).
• Future research should focus on mechanistic and molecular studies of human susceptibility alleles using these models.
• The convergence of genetic findings strengthens the translational value of mouse models for human SLE.
