title: [Role of distant lymphoid cell interactions for the development of in vitro antibody formation].
abstract: In order to clarify the nature of the recently described intercellular local interactions which were shown to inhibit the antibody-forming cells (AFC) proliferation in vitro, a possibility of realization of this effect at a distance was studied. It was shown that the population with a great number of cells could inhibit in vitro at a distance an increase of the AFC in the population of cells separated from the former by a millipore filter, impermeable for the cells. The results were the same with the use of polymethylmetacrylate film (5 to 10 micrometer in thickness) impermeable for proteins with a molecular weight of 150000 daltons (125I-IgG-antibodies) and some ions (51CrO4), but permeable for other substances with low molecular weight.
