Immunological studies with liposome-bound corynetoxins.
Attempts were made to raise antibodies against corynetoxins, a family of toxins responsible for annual ryegrass toxicity. The glycolipid nature of corynetoxins made them ideally suited for incorporation into the structure of small unilamellar liposomes. Sheep were injected with corynetoxin liposomes with and without adjuvants such as lipid A and muramyl dipeptide, and the sera tested for anti-corynetoxin antibody. Similarly, rabbits were injected with hydrolysed corynetoxin coupled to human IgG and keyhole limpet haemocyanin and with corynetoxin coupled to bovine serum albumin. These preparations were administered with complete Freund's adjuvant. The failure of any of these preparations to elicit an anti-corynetoxin antibody response in either sheep or rabbits is discussed.
