DNA mutations are essential to the rapid development of an array of antibody-producing immune cells called B cells that collectively can recognize a vast number of specific targets.
A new study investigated whether a specific population of local Bmem cells in the proximal LNs produce secondary GC responses that are different from those at distal sites and if the location in humoral immunity is relevant only to nonlymphoid tissues.
Researchers from the United States have now found that the immune recall induced by a two-dose primary series of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination after an initial natural infection highly improves the longevity of the antibodies as well as induces an enhanced breadth of protection across the SARS-CoV-2 variants.
Researchers performed an unbiased evaluation of the early memory B cell repertoire specific for the Omicron and Delta variants of SARS-CoV-2.
