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.
