摘要: Abstract The site of antigen encounter influences the Ig-distribution and homing potentials circulating antibody-secreting cells (ASC) induced. After oral administration, majority ASC secrete mucosal Ig-isotype, IgA, all them express gut receptor (HR), α 4 β 7 , thus implying these cells. Parenteral protein vaccine induces an IgG-dominated response with a low proportion expressing However, polysaccharide vaccine, even if administered parenterally, elicits IgA-dominated response, hence suggesting to mucosa. In order study influence nature on targeting present work compares in humans after administration Salmonella Typhi Ty21a (antigen studied: O-9,12 polysaccharide), recombinant cholera toxin B-subunit, CTB protein), parenteral pneumococcal Pnc capsular 19F) or tetanus toxoid TT protein). was expressed higher induced by (99%) than (70%) (63%). l -selectin, peripheral lymph node HR, smaller (37%) (43%) those (78%) (81%). results imply that has profound effect it does not seem response.
