Researchers found that follicular helper T-cells respond in different ways to structural proteins in COVID-19. They have been studying how the response happens over time.
Several studies report the observance of helper T-cell responses to the virus that causes COVID-19, SARS-CoV-2, in over 80% of individuals recovering from COVID-19. Besides helping in developing cytotoxic T cells, helper T cells stimulate B cells to produce antibodies. Therefore, T cells may help in the development of neutralizing antibodies against SARS-CoV-2.
