New Delhi, March 28 (NationPress) An international team of researchers has introduced a groundbreaking technique aimed at enabling the immune system to identify and combat cancer cells by prompting them to reveal their presence.

Led by the Weizmann Institute of Science in Israel, the study highlights that cancer cells often escape immune detection by exhibiting minimal suspicious proteins that the immune system can recognize and target, as reported by Xinhua news agency.

The findings, published in the journal Cancer Cell, detail how the research team, which includes experts from the US and Germany, disrupted protein synthesis in cancer cells, compelling them to produce abnormal, identifiable proteins that could elicit a robust immune response capable of eliminating cancer cells.

In experiments involving mouse models, this approach has demonstrated effectiveness in activating immune cells to seek out and destroy cancer cells, thereby slowing down tumor growth.

When combined with existing immunotherapy techniques, this new method resulted in tumor eradication in approximately 40 percent of the mice, according to Yardena Samuels, the lead researcher.

“An established immunotherapy that previously showed no efficacy against the specific melanoma we investigated became significantly effective after we disrupted the translation process in the mice's cancer cells,” explained Samuels.

“This combined approach led to either the complete eradication or considerable reduction of tumors in about 40 percent of the mice,” she added.

Researchers are optimistic that this innovation could enhance cancer treatments, particularly for patients with cancers that have limited mutations.

“Identifying a new predictive measure for immunotherapy effectiveness will enable healthcare providers to administer treatment to patients who were previously deemed ineligible,” noted Samuels.

The team is currently investigating the application of this technique to various other cancers, including breast, pancreatic, and colorectal cancers, with hopes that it will facilitate the development of more effective and comprehensive cancer therapies in the future.

“Given that the translation process is consistent across different cell types, any treatment that successfully disrupts this process in one specific cancer cell type could potentially be beneficial against multiple cancer types,” the team stated.
