Earlier Disease Detection on the Horizon

At the University of Edinburgh, researchers have been working to more accurately examine specific parts of different cells. In order to accomplish this task, they created probes that are able to light up certain areas of individual cells. This new invention has a slew of implications for cell research, but it also has the potential to vastly improve the medical field.

The probes have so far been tested successfully on fungal cells. It is speculated that they can be used to light up human cells from blood samples. If this speculation turns out to be fact, doctors will be able to examine the cells of their patients and spot early warning signs of serious diseases, such as cancer.

The probes themselves were created using peptide. Peptides are small molecules made up of short, linked chains of amino acids. The researchers have used individual peptides bonded with fluorescent tags to light up a specific target on a cell. Researchers use microscopes to see how the fluorescent light moves throughout the cell, and where it ultimately  settles.

Another useful facet of the probes is that they are highly sensitive. They are able to show researchers an accurate output of any part of the cell, which means researchers will be able to see if anything in the cell is out of the ordinary. Any change in how the molecule appears or is built could point to early signs of a disease. It can also help with more accurately tracking a patient’s response to treatment. Instead of treating a patient and waiting to see if the treatment produces any real change, doctors will be able to witness any alterations happening directly in the cells. This will allow them to determine if a treatment is working, and can change the course of the treatment early on if need be.

The research that these scientists have accomplished can revolutionize the way we approach disease. Instead of waiting to see if conditions get worse, or become more of a problem in the future, doctors will be able to predict the trajectory of a condition early on. Patients will be able to receive treatment for a condition at a point where it is not yet affecting their lives. This could improve quality of life, lower medical costs long term, and even save lives.

The researchers hope that their probes will someday be able to be used in routine scans, such as PET scans, so it becomes a standard in the medical industry for diseases to be diagnosed at their earliest stage. One can only hope that such innovation is spread throughout the medical sphere soon.
