Regulation of lymphoblast traffic and localization in mucosal tissues, with emphasis on IgA

J Bienenstock et al. Fed Proc. 1983 Dec.

Abstract

A fundamentally important factor in the expression of immunity at mucosal sites is the migration of primed lymphocytes to, from, and among mucosal tissues. Despite considerable information in recent years on the selective localization of B lymphoblasts, especially those destined to make IgA antibodies in mucosal tissues, the basis for this remains obscure. Several cell-associated factors such as surface characteristics, histo-compatibility type, and organ derivation of the cells play a significant role for T and B lymphoblast localization. Factors that regulate lymphoblast delivery to tissues, such as blood flow, or control emigration from tissues, such as arachidonic acid metabolites, are discussed. Finally, factors such as the presence or absence of high endothelial venules, isotype-specific T helper cells, sex hormones, antigen, macrophages, and iron all may play a significant role in mucosal lymphoblast localization.
