Thus, administration of transfer factor transfers the high responder phenotype to low responder recipients.

Dialysates from high responder strains contained transfer factor that would transfer delayed hypersensitivity to both high and low responder recipients.

Results: A large number of genes with differential expression between high and low responders were identified, with no overlap between brain regions.

To further investigate this issue, rats were subjected to a contextual fear conditioning task and then classified as high or low responders according to performance.

A decrease in biliary cholesterol in low responders treated with ezetimibe was associated with a decrease in hepatic expression of ABCG5 and ABCG8.
