Past Coronavirus Infections May Leave behind T Cells That Recognize SARS-CoV-2 / Infezioni passate da coronavirus possono lasciare alle spalle le cellule T che riconoscono la SARS-CoV-2
Past Coronavirus Infections May Leave behind T Cells That Recognize SARS-CoV-2 Segnalato dal Dott. Giuseppe Cotellessa / Reported by Dr. Giuseppe Cotellessa Understanding why some people develop severe symptoms following a SARS-CoV-2 infection while others remain asymptomatic is one of the most pressing questions in COVID-19 research today. The answer is undoubtedly complicated and multifaceted and will take years of research. One potentially crucial factor has now been identified by a team of researchers: prior exposure to coronaviruses. This insight is based on research involving T-helper cells, a specialized white blood cell which is essential to the regulation of our immune response. The researchers found that one in three people with no prior exposure to SARS-CoV-2 nonetheless has T-helper cells capable of recognizing the virus. The likely reason for this is that SARS-CoV-2 shares certain structural similarities with other coronaviruses. The work is published in For their study,
