[Further study of the problem of specific cellular receptors in delayed hypersensitivity].
The work presents the materials obtained as a result of the further study of specific T lymphocyte receptors with the use of so-called receptor antisera, i. e. antisera against the lymphoid cells of mice sensitized with one of the two antigens (Macobacterium tuberculosis or bovine gamma globulin); thus these differed from control antisera against the lymphoid cells of intact mice. These mouse antisera reacted with the lymphoid cells of guinea pigs in experiments of delayed-type hypersensitivity transfer. The cells of sensitized guinea pigs lost their ability to transfer hypersensitivity if, prior to their injection into the recipient guinea pigs, these cells were treated with the above-mentioned mouse antisera, i. e. antisera against the lymphoid cells of mice had a blocking effect on the lymphoid cells of guinea pigs. The blocking action of the antisera proved to be specific: antisera against the lymphoid cells of mice sensitized to bovine gamma gloublin blocked the cells of guinea pigs, also sensitized to bovine gamma globulins, but did not block the cells sensitized to Mycobacterium tuberculosis. The control antisera, taken in the same doses as the factor antisera, did not show a blocking effect on the specific activity of lymphoid cells.
