Splet26. jan. 2015 · Traditionally, class-switched B cells with mutated IgV genes and surface CD27 expression were regarded as “prototypical” memory B cells ( 5 ), although more recent data have shown that CD27 is a sufficient, but not essential, memory B-cell marker, because a small subset of IgG + CD27 − and potentially also IgM + CD27 − memory B cells has … Splet06. jun. 2024 · Proposed origins of double-negative (DN) B cells. Three models have been proposed regarding the origins of DN B cells, as shown in red boxes: (1) DN B cells might share precursor–product relationships with switched memory B cells; (2) DN B cells might be products of a defective GC reaction and develop through the extrafollicular pathway; …
