הסרת המסתורין ב-Vivo Bioluminescence Imaging של מודל עכבר למחלת Chagas למחקרי יעילות תרופות

Executive Industry Relevance

In vivo bioluminescence imaging (BLI) in Chagas disease mouse models enables real-time, quantitative assessment of antiparasitic drug efficacy, directly supporting early discovery and lead identification. This approach provides predictive confidence in distinguishing compounds that achieve parasitological cure from those with only transient effects, informing risk-adjusted portfolio decisions. The method's non-invasive, longitudinal monitoring reduces animal use and enhances translational continuity for neglected tropical disease pipelines.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables direct, quantitative tracking of Trypanosoma cruzi burden in live animals over time.
• Supports functional validation of therapeutic hypotheses by differentiating transient suppression from true parasitological cure.
• Facilitates mechanistic de-risking by revealing parasite persistence and relapse dynamics post-treatment.
• Improves predictive confidence for compound triage and advancement decisions.

Screening & Assay Development

• Provides a validated, reproducible system for evaluating compound efficacy in vivo.
• Standardizes quantitative readouts (bioluminescence flux) for cross-study comparability.
• Enables scalable, longitudinal assessment of multiple compounds and regimens within the same cohort.
• Supports robust assay development for downstream screening workflows.

Translational & Preclinical Research

• Aligns preclinical efficacy endpoints with disease-relevant infection dynamics and relapse patterns.
• Enables continuity from discovery through preclinical validation by tracking chronic and acute infection phases.
• Supports translational biomarker development through quantitative imaging outputs.
• Reduces late-stage biological risk by providing early, actionable efficacy data.
