Setting it Straight: Viruses, Vaccines and COVID-19: recruitment to the lymph nodes
As clinical investigators try to understand what’s happening in COVID-19 immunity, it’s easy to take a blood sample and analyse the various subsets of circulating lymphocytes but much harder to look closely at the events in the regional lymph nodes (LNs) where the virus-specific response develops. Radiologists using imaging techniques can, of course, provide a lot of relevant information re LN size and so forth, but sampling the cell populations in the LN requires a needle biopsy.
