Lrrk2 Knockout Rat
Model Detail >
Blue Fade Line
Nomenclature: LEH- Lrrk2 tm1sage
Genotype: Homozygous
Product number: TGRL4620
Research Applications
  • Parkinson's disease
  • Neuronal apoptosis

Developed in collaboration with The Michael J. Fox Foundation, this model contains a deletion of the Lrrk2 gene, encoding for the leucine-rich repeat kinase 2. Mutations in Lrrk2 are the most common monogenic cause of Parkinson’s disease. This model is useful in understanding Lrrk2 biology.

  • Homozygous knockout rats exhibit complete loss of target protein as demonstrated by Western blot
  • Lrrk2 knockout rats display dark kidneys, similar to observations made in Lrrk2 knockout mice
  • Lrrk2 knockout rats are significantly larger than wild type controls
  • Background Strain: Long Evans Hooded
  • Figure 1. Kidney pathology in Lrrk2 knockout rats
    Kidney from a Lrrk2 knockout rat at 37 weeks of age. The kidney is dark in color, a phenotype similar to observations in Lrrk2 knockout mice (Herzig MC, et al. Hum Mol Genet (2011) 20 (21): 4209–4223). Image courtesy of PsychoGenics.

    Lrrk2 knockout animals show no deficits in motor activity as assessed by rotarod at 12 months of age.

    Additional Information

    Lrrk2 mutations account for 5-6% of familial Parkinson’s dieases and 1-3% in sporadic PD. Collectively, these mutations result in the most common cause of PD, making this an important model for the study of Parkinson’s disease.
