[...]developmental stages of B cells, that is B220+CD43+IgM−IgD− (pro‐B), B220+CD43−IgM−IgD− (pre‐B), B220+CD43−IgM+IgD− (immature B) and B220+CD43−IgM+IgD+ (mature B), were detected in mouse BM, intestinal lamina propria (LPL) and Peyer's patches (PPs) by flow cytometry. [...]the expression levels of CD40, CD80 and MHC‐Ⅱ on B cells were detected in mouse SPL, MLN and PPs. [...]we examined the Secretory Immunoglobulin A (SIgA) level in intestinal lavage fluid and serum IgM, IgA and Immunoglobulin G (IgG) by ELISA. [...]LGG intervention can promote the development and maturation of B lymphocytes, enhance the activation and antigen‐presentation ability of B lymphocytes, and regulate the secretion of immunoglobulin by B lymphocytes. [...]LGG can regulate the mucosal immunity and humoural immunity of mice.
