High-Throughput Assay for the Identification of Drugs Targeting the NF-kB Pathway

Tech ID: 02-05


Researchers at National Jewish Health have developed a microscopy-based visual assay to measure the antigen-receptor activation of an intermediate molecule located upstream of NF-kB


Potential Applications

Identification of compounds as potential agents against inflammatory diseases, immune diseases and cancer


Advantages of Invention

The assay targets Bcl10, a specific intermediate protein of the NF- kB pathway, and it is compatible with epifluorescence/confocal microscopy


State of Development

Using cell lines developed in-house, National Jewish Health scientists have demonstrated that T cell receptor activation of NF-kB involves the dynamic relocalization of the signaling intermediate Bcl10. This protein movement can be visualized by confocal or epifluorescence microscopy using a fluorescent marker (such as GFP) or antibodies.
