The best part about this approach is that it targets the very thing that makes viruses infectious - all viruses target a cell surface receptor to gain entry into the cell. After gaining entry they commandeer the host cell machinery to replicate. If the virus did not have the ability to bind the receptor it would be ineffective. BME's are even more exciting because potentially these dont involve cellular engineering presumably - small protein with part receptor part immune engager - this lends itself to being made at very large scale whereas the cell based therapies represent a huge logistical challenge if individual patient apheresis is required.
"Major advantages of our CBRs and BMEs for combatting viral infections include:
(1) the use of a "bait" makes CBRs and BMEs insensitive to mutations of the targeted virus, preventing the development of resistance (unlike antibodies); as long as the virus is infective and uses the same "door" to enter a cell, it will be eliminated by CBR-based treatments. The bait resembles a handle of the door that the virus uses to enter a cell.
(2) CBRs and BMEs are assembled from parts of naturally occurring cellular receptors and/or engagers that are responsible for the function of immune cells and endow the host's own immune system with the ability to destroy invading pathogens.
(3) CBRs and BMEs are modular synthetic receptors and/or immune cell engagers that can be reconfigured rapidly to attack almost any virus. It is important to stress that this new technology also works in cancer, on malignant cells. This work thus strengthens the Company's anti-cancer work, and importantly opens up many opportunities to work with public bodies, such as the military, the National Institutes of Health, the Biomedical Advanced Research and Development Authority ("BARDA"), as well as other leading public health-focused foundations."
