Biological process

mature B cell development involved in immune response, mature B cell differentiation during immune response, mature B lymphocyte differentiation during immune response, mature B-cell differentiation during immune response, mature B-lymphocyte differentiation during immune response

The process in which a naive B cell acquires the specialized features of a mature or memory B cell during an immune response.

Note that immunologists typically use the word 'development' to refer to cells of B or T cell lineages undergoing the process that GO describes as 'cell differentiation'.
