transfer factor

n. Any of various small proteins that are obtained from donors with cell-mediated immunity to certain antigens and can confer this immunity when given to nonimmune recipients.

trans′fer fac`tor

n. a lymphocyte product that, when extracted from T cells of an individual with immunity to a particular antigen, can confer that immunity when administered to another individual of the same species. [1955–60]

transfer factor

(TF) a factor occurring in sensitized lymphocytes that has the capacity to transfer delayed hypersensitivity to a normal (nonreactive) individual. It confers cell-mediated immunity and therefore has been found to be useful in treating conditions in which there is a disorder of immune response. As an adjunct to antibiotic therapy it is useful in the treatment of such antibiotic-resistant diseases as candidiasis, coccidioidomycosis, and leprosy.

trans·fer fac·tor

1. the transfer gene of a conjugative plasmid, especially of the resistance plasmid; 2. a dialyzable extract that is obtained from the leukocytes of a person with a delayed-type sensitivity and that, after injection into the skin of a nonsensitive person, transfers the specific sensitivity to the recipient; 3. Synonym(s): elongation factor
