In Vivo Model Development for Lupus Erythematosus
Protheragen offers comprehensive in vivo model development services for Lupus Erythematosus, supporting pharmaceutical and academic partners in advancing preclinical research and therapeutic discovery. Our expertise in animal modeling ensures the creation of robust, reliable, and translationally relevant models tailored to meet the specific needs of lupus research and drug development.
Lupus Erythematosus is a complex autoimmune disease characterized by systemic inflammation and multi-organ involvement, posing significant challenges for therapeutic development. Animal models play a pivotal role in elucidating disease mechanisms, evaluating drug efficacy, and translating findings to human clinical trials. At Protheragen, we utilize a range of well-established species, including mice and rats, with a focus on strains such as NZB/W F1, MRL/lpr, and BALB/c, which closely mimic the immunopathology and clinical manifestations observed in human lupus. These models enable the investigation of autoantibody production, renal pathology, and immune dysregulation, providing critical insights into disease progression and treatment response.
Genetic models involve the use of animals with spontaneous or engineered mutations that predispose them to lupus-like disease. Notable examples include the NZB/W F1 and MRL/lpr mouse strains, which develop hallmark features such as autoantibody production, glomerulonephritis, and lymphadenopathy. Methodology includes selective breeding or targeted gene modification. Key advantages are high reproducibility, close resemblance to human disease phenotypes, and suitability for chronic efficacy and mechanistic studies. These models are primarily used for evaluating long-term therapeutic interventions, studying disease pathogenesis, and identifying genetic contributors to autoimmunity.
Chemically-induced models are established by administering agents such as pristane or polyinosinic:polycytidylic acid (poly I:C) to trigger lupus-like autoimmunity in otherwise healthy animals. The methodology typically involves a single or repeated intraperitoneal injection, leading to the development of autoantibodies and organ involvement. Advantages include controlled disease induction, flexibility in experimental design, and the ability to study environmental triggers of lupus. These models are valuable for short-term efficacy screening, mechanistic studies of environmental factors, and testing preventive strategies.
Humanized models are generated by engrafting immunodeficient mice with human immune cells or tissues, resulting in a chimeric system that recapitulates key aspects of human lupus immunopathology. Methodology includes transplantation of human peripheral blood mononuclear cells (PBMCs) or hematopoietic stem cells. Major advantages include the ability to evaluate human-specific immune responses, test human-targeted therapies, and bridge the translational gap between preclinical and clinical studies. These models are particularly suited for assessing the efficacy and safety of novel biologics, cell therapies, and personalized medicine approaches.
Protheragen delivers a complete solution for in vivo Lupus Erythematosus model development, encompassing model selection, customized protocol design, animal procurement, disease induction, and comprehensive in vivo and ex vivo analysis. Key efficacy endpoints include survival rate, proteinuria, renal histopathology, autoantibody titers (e.g., anti-dsDNA, ANA), cytokine profiling, and immune cell phenotyping. Our analytical capabilities extend to flow cytometry, ELISA, immunohistochemistry, qPCR, and advanced imaging. Stringent quality control measures are integrated throughout the process, including validation of disease induction, standardized scoring systems, and adherence to ethical and regulatory guidelines, ensuring data integrity and reproducibility.
