These technologies enable researchers to gain insights into disease mechanisms, evaluate therapeutic efficacy, and accelerate the drug development pipeline, all within the context of living organisms.
Bioluminescence imaging (BLI) relies on the emission of light by a chemical reaction within living organisms, often involving an enzyme like luciferase. This technique is particularly advantageous in preclinical studies due to its high sensitivity and the ability to track dynamic biological processes in real-time. For instance, by genetically engineering animal models to express luciferase in certain tissues or tumors, researchers can non-invasively monitor disease progression and therapeutic responses over time. This application is invaluable in cancer research, where tracking tumor growth and metastasis is crucial for evaluating potential treatments.
On the other hand, fluorescent imaging utilizes fluorescent proteins or dyes to visualize specific cells or biological structures within animal models. This method offers high spatial resolution, making it suitable for detailed anatomical studies and tracking cellular events. Advances in fluorescent imaging have led to the development of sophisticated techniques such as Förster Resonance Energy Transfer (FRET) and fluorescence lifetime imaging microscopy (FLIM), further enhancing the capacity to study molecular interactions and cellular environments in vivo.
One notable case study involves using fluorescent imaging to understand neurodegenerative diseases.
