Specifically, the study results, published in the journal PLOS Pathogens on March 22, show how T-cell-based immunotherapy can be applied to immunocompromised patients.

T cells are the central white blood cells in the human adaptive immune response, capable of detecting a wide range of harmful cells to destroy, including tumor cells and many other viruses.

Through blood analysis of 60 volunteers with COVID-19 in the Australian state of Queensland, the study found that some blood samples have the ability to generate T cells. Scientists say, if successful, they T-cell transplants for patients with severe COVID-19 symptoms can be compared with chemotherapy in cancer patients.

Lead researcher Corey Smith said the study now offers hope that it is possible to develop a T-cell-based immunotherapy capable of treating the most severe COVID-19 patients, regardless of person. which variant of the SARS-CoV-2 virus.

The study notes that additional intervention strategies will still be important, given the potential for new variants of SARS-CoV-2 ang to emerge and be resistant to vaccines. Although it is not a substitute for a vaccine, T-cell-based immunotherapy could be another option for patients with the right conditions, Smith said.
