Restoration of cell-mediated immune responses with transfer factor.

Five anergic patients with chronic mucocutaneous candidiasis were given transfer factor from donors with positive delayed reactions to Candida. In each recipient, the delayed skin reactions of the transfer factor donors appeared in the recipients and no recipient developed reactivities not possessed by the donor. Prior to injection of transfer factor, in vitro stimulation of the patients' lymphocytes with antigens did not result in MIF production, however, after transfer factor this response was positive. Therapy with transfer factor alone did not have therapeutic benefit, however, in 2 patients treatment with amphotericin-B followed by transfer factor has produced cutaneous remissions of 18 months.

Chemotactic activity in dialyzable transfer factor.

Dialyzable transfer factor from human leukocytes was found to be strongly chemotactic for granulocytes and weakly chemotactic for monocytes in vitro. Chemotactic properties were also demonstrated in vivo in rhesus monkey skin. Initial purification of the dialyzable transfer factor by Sephadex G-25 chromatography revealed multiple fractions containing material with 255-nm absorbance. The fractions containing chemotactic activity were also capable of transferring delayed hypersensitivity to rhesus monkeys. This chemotactic material has an apparent molecular weight of 5000 daltons or less and was not inactivated by goat antibody to components C3 or C5 of human complement; chemotactic activity was lost after storage for two weeks at 4 degrees and the activity of two of three preparations was decreased by heating for 30 min at 56 degrees . This previously undescribed chemotactic activity of dialyzable transfer factor may have significance in relation to cell-mediated immune responses.

Corneal cellular immunity in the guinea pig.

Guinea pigs were sensitized to cornea or skin by grafting or by injection of corneal homogenates in complete Freund's adjuvant. Delayed-type hypersensitivity responses were studied with intradermal skin tests with tissue extracts. Cellular immune responses by lymph node cells (LNC) and peritoneal exudate cells (PEC) were examined in vitro with the thymidine incorporation and macrophage migration inhibition (MIF) assays, and in vivo by passive transfer of delayed-type hypersensitivity. Both the in vivo and in vitro tests demonstrated that animals sensitized either by grafts or parenteral immunization were systemically hypersensitive. Peritoneal exudate cells from animals passively sensitized with either PEC or LNC responded to antigenic stimulation in vitro with MIF production. Furthermore, the skin tests and in vitro assays demonstrated cross reactively with antigens from cornea and skin but not with homogenates from liver.
