Abstract
Human transfer factor was prepared from normal donors with marked skin reactivity against common microbial antigens by dialysis of lymphocyte extracts versus tissue culture medium (TFmd). Several batches of TFmd were tested for their ability to specifically increase the DNA synthesis of unsensitized lymphocytes in vitro in the presence of the corresponding antigens (PPD, SKSD, Candida, Histoplasmin). No transfer of immunologic reactivity by TFmd was observed. There was, however, a significant unspecific inhibition by TFmd of lymphocyte cultures stimulated by antigens, PHA or allogeneic cells. Menschlicher Transferfaktor wurde von normalen Spendern mit ausgeprägten verzögerten Hautreaktionen gegen gewöhnliche mikrobielle Antigene durch Dialyse von Lymphozytenextrakt gegen Gewebekulturmedium hergestellt (TFmd). Verschiedene Präparationen von TFmd wurden auf ihre Fähigkeit untersucht, die DNA-Synthese von unsensibilisierten Lymphozyten in vitro in Anwesenheit der korrespondierenden Antigene (PPD, SKSD, Candida, Histoplasmin) spezifisch zu steigern. In keinem Fall konnte ein Transfer immunologischer Reaktivität durch TFmd nachgewiesen werden. Jedoch ließ sich häufig ein signifikanter, unspezifischer Hemmeffekt des TFmd in Lymphozytenkulturen feststellen, die mit Antigenen, PHA oder allogeneischen Zellen stimuliert wurden.Keywords
