Atherosclerosis
TNO specialises in highly translatable preclinical atherosclerosis research, supporting the development and evaluation of novel therapeutic compounds. By combining decades of expertise in cardiovascular disease biology with validated in vivo models and advanced histopathological analysis, we generate robust, clinically relevant data that supports confident decision-making. Our proprietary APOE*3-Leiden, APOE*3-Leiden.CETP and Ldlr-/-.Leiden mouse models enable the assessment of treatment effects on lipid metabolism, inflammation, and disease progression. Whether in preventive or therapeutic study designs, we help translate preclinical insights into meaningful outcomes for drug development.

A powerful approach to accelerate cardiovascular drug development
TNO supports pharmaceutical and biotech organisations in evaluating the efficacy of novel compounds targeting cardiovascular disease. By combining translational in vivo models with quantitative histopathology, we provide deep insights into lesion development, progression, and treatment response. Our approach allows you to assess compound performance under physiologically relevant conditions, benchmark against existing therapies, and generate robust datasets that support early decision-making in the development pipeline.

Key capabilities
Translational efficacy models
Validated mouse models with demonstrated relevance to human lipid metabolism and disease progression.
Histopathology & lesion quantification
Quantitative analysis of lesion area and composition with standardised workflows and reduced variability.
Flexible study designs
Support for both preventive (progression) and therapeutic (regression) study setups.
End-to-end expertise
From study design and execution to data analysis and interpretation.
AI-powered histopathology
Our AI-supported histopathology platform enhances the analysis of atherosclerotic lesions by enabling accurate and standardised quantification across entire tissue sections.
AI-based histopathology allows for precise delineation of lesion boundaries across the aortic root, reducing variability and improving sensitivity in detecting treatment effects. This results in more robust and reproducible datasets, supporting stronger and more reliable conclusions from preclinical studies.
Translational model platform
Our APOE*3-Leiden(.CETP) and Ldlr-/-.Leiden mouse models develop diet-induced dyslipidaemia with a lipoprotein profile that closely resembles humans. In these models, cholesterol is primarily carried in VLDL and LDL particles, in contrast to wild-type mice where HDL predominates and atherosclerosis does not develop.
This makes our models highly suitable for studying therapeutic interventions in a clinically relevant context.
Use cases

Drug efficacy testing
Evaluate the effect of compounds on atherosclerosis progression or regression.
