T-cell technology could be used to treat ovarian tumours with no adverse effects


There are various treatments available now to treat ovarian cancer. But those do not have long lasting results. Lots of research has been conducted to treat cancer. Many researchers had developed immunotherapies that operate T-cells to selectively remove ovarian tumor cells. But the proper beneficial target for ovarian cancers has remained mysterious.

Now, scientists from the Wistar Institute have demonstrated a receptor protein. This receptor protein is articulate on different types of ovarian tumor cell’s surface including clear cell and mucinous ovarian tumors. The clear cell and mucinous are two of the most aggressive subtypes of the disease. This protein shows a particular therapeutic target in a range of ovarian tumors. Furthermore, scientists found that T-cell technology could be controlled to diagnose such tumors without any toxic effects.

Scientists started their work on this research almost before 4 years ago. The research aim was to find effective and safe immunologic way to diagnose epithelial ovarian tumors. Scientists found receptor protein expressed entirely on ovarian cells. It was expressed in 70 percent of endometrioid carcinomas, 67 percent of mucinous ovarian carcinomas, and 33 percent of clear cell ovarian carcinomas. Scientists also found that this protein is not expressed in any other tissue. This makes them utilize revolutionary targeted T-cell technology to potentially eliminate cancerous cells in patients. This novel method will target only affected tissues by removing cancerous cells.

In immunotherapy, chimeric antigen receptor (CAR) T-cell technology was used. CARs proteins allow T cells to detect particular antigens found on tumors and remove them. This resulted in remarkable results in cancer patients, but so far it has been limited to B-cell blood cancers like chronic lymphocytic leukemia.

Scientists just modified CAR technology version, which they mention as imaginary endocrine receptor-expressing T-cells (CER-T). These T-cells are directed to ovarian cancer cells expressing FSHR with the full-length sequence of the FSH hormone instead of the antibody fragment typically used in CAR-T cells. They were able to activate elimination of placed tumors of human origin in immunodeficient mice. Additionally, the researchers didn’t recognize unfavorable effects while managing T-cells of mouse origin in tumour-bearing mice that otherwise had a normal immune response. There was no evidence of weight loss, signs of distress, no effect on healthy tissues, and levels of liver enzymes and glucose remained unaffected by the treatment.

It does not cause weight loss, irritation. It does not effect on healthy tissues, liver enzymes, levels and glucose.

Alfredo Perales-Puchalt, a postdoctoral fellow in the Conejo-Garcia lab, said, “Ideally, we’d like to see this technology used after initial treatment with surgery and chemotherapy. Recurrence remains a major concern in the treatment of ovarian cancer, and so we believe the method we studied could be used to rid the patient of residual disease and drastically reduce the chance of cancer returning.”
