Summary
Near-infrared photoimmunotherapy (NIR-PIT) uses antibody-photoabsorber conjugates and light to induce cancer cell death. Selecting optimal membrane targets and antibodies is crucial for developing future NIR-PIT drugs.
Area of Science:
- Oncology
- Immunology
- Biotechnology
Background:
- Near-infrared photoimmunotherapy (NIR-PIT) is an emerging cancer treatment.
- It utilizes antibody-photoabsorber conjugates (e.g., IRDye700DX [IR700]) activated by near-infrared (NIR) light.
- This therapy induces targeted necrotic cell death via membrane damage.
Purpose of the Study:
- To review existing membrane targets and antibodies used in NIR-PIT.
- To focus on the characteristics of these molecules for future drug development.
- To guide the selection of optimal targets and antibodies for enhanced NIR-PIT efficacy.
Main Methods:
- Literature review of studies on NIR-PIT.
- Analysis of reported membrane target molecules and specific monoclonal antibodies.
- Summarization of the characteristics of identified targets and antibodies.
Main Results:
- Various membrane proteins have been identified as potential targets for NIR-PIT.

02:57Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

01:05Total Internal Reflection Fluorescence Microscopy
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.
