How COVID-19 Led to a Cancer Research Breakthrough
Scientists at Northwestern Medicine have made an unexpected discovery linking COVID-19 infection to potential cancer treatment. Their research, published in The Journal of Clinical Investigation, reveals how the body's response to the COVID-19 virus might help fight cancer.
The Key Discovery
During their research, scientists found that RNA from the SARS-CoV-2 virus triggers the development of special immune cells called "inducible nonclassical monocytes" (I-NCMs). These cells demonstrate remarkable anti-cancer properties and could potentially help treat cancers that resist current therapies.
How These Special Cells Work
These I-NCMs are particularly interesting because of their unique abilities:
They can travel through both blood vessels and surrounding tissue where tumors grow
Unlike regular immune cells, they retain a special receptor (CCR2) that lets them reach tumor sites
Once at the tumor, they signal the body's natural killer cells to attack the cancer
What Makes This Different
Most immune cells that patrol blood vessels can't enter tumor sites directly. These special I-NCMs can do both, making them potentially more effective at fighting cancer. The research team found positive responses against several types of cancer, including:
Melanoma
Lung cancer
Breast cancer
Colon cancer
Looking Forward
Dr. Ankit Bharat, Chief of Thoracic Surgery at Northwestern Medicine, emphasizes that while this research is promising, it's still in early stages. The next step involves clinical trials to determine if these findings can safely help cancer patients.
One potential application could be helping patients in Northwestern's DREAM Program, which provides double-lung transplants to patients with advanced lung cancers. These findings might offer new treatment options without risking organ rejection.
The Research Impact
This discovery offers a new direction in cancer treatment research, particularly for patients who haven't responded to other treatments. It demonstrates how unexpected connections - in this case between COVID-19 and cancer treatment - can lead to important medical insights.
The research, funded by the National Institutes of Health and Canning Thoracic Institute, represents collaboration between scientists at Northwestern University Feinberg School of Medicine and clinicians at Northwestern Memorial Hospital.
While more research is needed, this discovery provides a promising new avenue for understanding and potentially treating aggressive cancers.
