Abstract
The mucosal addressin cellular adhesion molecule 1 (MAdCAM) is expressed on the venules of the gut associated lymphoid tissue (GALT); it is also expressed on the venules of the lobules of the mammary gland. We have previously found that MAdCAM-targeting using a rat anti-MAdCAM monoclonal Ab as both antigen and targeting moiety resulted in an enhanced local IgA gut response. We therefore surmised that such targeting may also enhance IgA responses in the mammary gland. We show that our model antigen localizes to the lobules of the mammary glands as well as the GALT, but not to the draining lymph nodes and that targeting MAdCAM results in secretory IgA responses in the milk. We provide evidence that this milk IgA Ab is of a secretory nature and is consistent with derivation from gut plasmablasts that have migrated to the mammary gland. Targeting MAdCAM may be a way for a novel vaccine strategy that affords protection to the mammary gland and the suckling neonate. (c) 2006 Elsevier Ltd. All rights reserved.
