title: Cytidine-5'-diphospho-choline conjugates. II.--Immunogenicity in rats.
abstract: Cytidine diphospho-choline (CDPC) derivatives of human serum albumin (HSA) are immunogenic in the rat when injected in adjuvants. They induce a very rapid synthesis of IgM anti-phosphorylcholine antibodies which was followed by the synthesis of anti-CDPC antibodies and of anti-HSA antibodies. The activated nucleotide was able to induce specific skin sensitivity in rats after one skin painting. Gastric intubations of rats with low doses of HSA conjugates 8 days before an infection with the nematode Nippostrongylus brasiliensis were followed by a reduction of the resulting intestinal worm burden.
