Liposomal encapsulation augments delayed hypersensitivity reactions to tuberculin proteins.
Encapsulation of purified tuberculoproteins in liposomes augmented their ability to elicit delayed hypersensitivity reactions in BCG-immune rats. The effect was most marked with a low-molecular-weight tuberculopeptide that was relatively poor at eliciting reactions when in free form. These findings indicate that, in addition to the antigenic nature of the material, the physical form of presentation of mycobacterial test antigens can influence their ability to elicit hypersensitivity reactions.
