Protein deprivation causes reversible impairment of mucosal immune response to cholera toxoid/toxin in rat gut [12]

Secretory antibodies may be the major defence against mucosal infections, especially those due to viruses and non-invasive pathogens such as Vibrio cholerae and toxinogenic Escherichia coli. The high incidence of mucosal infections in malnourished protein-deficient children1 may result from defective antibody production2, but evidence for this is conflicting3. We report here that protein deficiency markedly impairs the mucosal immune response to cholera toxoid/toxin (CT), a protein antigen, in rats and that this impairment is rapidly reversed by refeeding.
