Abstract:
To study the importance of the bone marrow in the production of specific antibodies after a mucosal immunization with cholera toxin, the IgG, IgA and IgM specific antibody forming cells were evaluated by ELISPOT in Peyer patches, mesenteric lymph node (MLN), spleen, blood and bone marrow (BM). When 50-day-old rats were immunized intra-Peyer patches, a similar number of IgG and IgA antitoxin antibody forming cells (AFC) were found in the BM, whereas in the other lymphoid tissues a higher number of IgG antitoxin was found. In all sites the peak of AFC was obtained 2 weeks after immunization. The administration of CT to 35-week-old rats resulted in a stronger immune response in all lymphoid tissues studied, but the proportion of antitoxin AFC contributed by the BM had not changed. One oral dose of cholera toxin resulted in a low number of antitoxin AFC, whereas when two or three doses of CT were administered orally an increase in the number of AFC was observed in the BM, reaching similar or higher numbers of IgG and IgA AFC than in the spleen. In all cases the highest number of AFC 106 cells was observed in the MLN, whereas antitoxin AFC were not found in the blood. The total number of AFC recovered from each organ was calculated taken into account that the BM of one femur represents 9% of the total BM. So, it was found that the BM is an important site in the production of IgG antitoxin antibodies, being the main site in the IgA antitoxin antibody production. © 1995.
