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

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.

transfer factor (TF)

a leukocyte extract that transfers delayed hypersensitivity from one person to another. Transfer factor has been studied for its possible use in the treatment of chronic mucocutaneous candidiasis and Wiskott-Aldrich syndrome and as a means of transferring antitumor immunity to patients with various types of cancer.

trans·fer fac·tor

(trans'fĕr fak'tŏr)
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, following injection into the skin of a nonsensitive person, transfers the specific sensitivity to the recipient.
3. Synonym(s): elongation factor.

transfer factor

A LYMPHOKINE released by T cells that activates MACROPHAGES and prompts them to attack fungi.

transfer factor,

n a natural protein that is used to treat bacterial and viral diseases postulated to transfer im-munity from one cell to another, thereby boosting immune function.

transfer factor

a factor extractable from sensitized lymphocytes of some species that has the capacity to transfer delayed hypersensitivity to a normal (nonreactive) individual; abbreviated TF. 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 has been used in the treatment of such antibiotic-resistant diseases as candidiasis and coccidioidomycosis.

This study seeks to investigate the levels of toxic (zinc, nickel, lead, cadmium, chromium) and major (sodium, potassium, magnesium, calcium) metals in cucumber plant parts (fruit, leaf, shoot, root) and soil; assess the bioconcentration factor (BCF) and transfer factors (TF) in the plant; determine the pollution status of farm soil using pollution indices-concentration factor (CF) and geoaccumulation index (Igeo); classify and determine the source of metals pollution using multivariate analysis; and, also the risk associated with ingestion of cucumber fruit and soil.
