Adaptive immune responses to SARS-CoV-2 persist in the pharyngeal lymphoid tissue of children

The study titled “Adaptive immune responses to SARS-CoV-2 persist in the pharyngeal lymphoid tissue of children” delves into the immune response to SARS-CoV-2, particularly focusing on the immune landscape in the upper respiratory tract. Utilizing samples from children undergoing tonsillectomy and adenoidectomy during the COVID-19 pandemic, this study provides insights into the long-term adaptive immune responses post-infection. Here’s a detailed summary: Study Overview: Key Findings: Conclusions and Implications: The study demonstrates that children who recover from COVID-19 have persistent adaptive immune responses in the pharyngeal lymphoid tissues, with sustained germinal center and antiviral lymphocyte populations. The presence of SARS-CoV-2-specific B…
