Mouse inbred MRL lpr is a strain of laboratory mice commonly used in scientific research. This strain is characterized by its genetic predisposition to develop systemic lupus erythematosus (SLE), a chronic autoimmune disease. Synonyms for this specific strain might include MRL/lpr mice or MRL lupus-prone mice. These mice serve as valuable models for studying the mechanisms and potential treatments for SLE and other autoimmune diseases. Through various genetic and immunological approaches, researchers can gain insights into the pathogenesis of SLE and test novel therapeutic interventions. The use of mouse inbred MRL lpr strain has significantly contributed to advancements in our understanding of autoimmune disorders.
