Protection against pneumococcal infection in mice conferred by phosphocholine-binding antibodies: specificity of the phosphocholine binding and relation to several types.
1983
Abstract
Some anti-phosphocholine antibodies protect mice against challenge with certain, but not all, pneumococcal types. We found that both their isotype and reactivity with the cell wall C-polysaccharide of encapsulated pneumococci, as measured by immunodiffusion, were important in predicting the protective activity of anti-phosphocholine antibodies. We propose that the specificity of the protective antibodies includes the backbone of the phosphocholine-containing structure.
