TY - JOUR T1 - Specific T cell factors exist JF - bioRxiv DO - 10.1101/100024 SP - 100024 AU - Geoffrey W. Hoffmann AU - Reginald M. Gorczynski Y1 - 2017/01/01 UR - http://biorxiv.org/content/early/2017/01/13/100024.abstract N2 - The symmetrical immune network theory has been developed since 1975 and is based on the existence of specific T cell factors. The existence of specific T cell factors is controversial. We confirm the existence of these specific immune system components by demonstrating that a rigorous 1975 experiment by Takemori and Tada can be reproduced. We also briefly review how specific T cell factors play a role in the induction of specific tolerance and in the induction of immunity according to the symmetrical immune network theory. ER -
