ABSTRACT The induction of immune responses to rectally administered recombinant cholera toxin B subunit (CTB) in humans was studied. Three immunizations induced high levels of CTB-specific antibody-secreting cells, particular of the immunoglobulin A isotype, in both rectum and peripheral blood. Antitoxin antibody responses in rectal secretions and serum were also found.

ABSTRACT The induction and dissemination of mucosal immune responses to recombinant cholera toxin B subunit (rCTB) administered into the ileal pouches of patients, who had been colectomized because of ulcerative colitis, was analyzed. Biopsies from the duodenum and ileal pouch were collected, along with peripheral blood and ileostomy fluids. Two immunizations induced strong CTB-specific immunoglobulin A (IgA) antibody-secreting cell (ASC) responses in the duodenum in five of five patients, whereas weaker and less-frequent ASC responses were noted in the ileal pouch. Intestine-derived CTB-specific IgA ASCs were found in peripheral blood in three of the five patients. The vaccination also induced significant IgA antitoxin titer rises in ileostomy fluid in all of the patients. Increased production of gamma interferon in cell cultures from the ileal pouch was found in four of five patients after the vaccination. These results clearly indicate that rCTB administered into the distal ileum is capable of inducing B-cell responses in the “entire” small intestine and that homing of immunocompetent cells occurs preferentially to the duodenum.
