dc.description.abstractIpomoea cameo Jacq. ssp. fistulosa (Mart. Ex Choisy; Convolvulaceae; I. cameo) possesses a toxic component: an indolizidine alkaloid swainsonine (SW) that has immunomodulatory effects due to its inhibition of glycoprotein metabolism. It is also known that SW is excreted into both the amniotic fluid and milk of female rats exposed to I. cameo. Thus, the aim of this study was to determine whether SW exposure, either in utero or from the milk of dams treated with I. cornea, modulates offspring immune function into adulthood. in addition, adult (70 days old) and juvenile rats (21 days old) were exposed to I. cameo in order to evaluate several other immune parameters: lymphoid organs relative weight and cellularity, humoral and cellular immune responses. Offspring exposed to I. cornea during lactation developed rheumatoid arthritis (RA) in adulthood after an immunogenic challenge. in addition, both adult and juvenile rats exposed to I. cameo showed discrepancies in several immune parameters, but did not exhibit any decrease in humoral immune response, which was enhanced at both ages. These findings indicate that SW modulates immune function in adult rats exposed to SW during lactation and in juvenile and adult rats exposed to SW as juveniles and adults, respectively.en
