The inhibition of migration of human peripheral blood cells in the presence of PPD was studied. It was found that migration inhibition of peripheral blood mononuclear cells (MN) from Mantoux-positive donors was far greater than the migration inhibition of peripheral blood leucocytes (PBL). Moreover, MN cells and T lymphocytes showed larger and more uniform areas of migration. In contrast, the migration of B lymphocytes and monocytes was poor. Further analysis using purified subpopulations of MN cells showed that PPD inhibited the migration of T lymphocytes but not of B lymphocytes and monocytes. Corresponding to these findings, lymphokine-containing supernatants also inhibited the migration of purified T cells from Matoux-negative donors. It was concluded that the T lymphocyte was the predominant cell in the MN cell population, which migrated, and was subject to inhibition by PPD or lymphokines. These results imply that the movement of human T lymphocytes may be influenced by soluble factors from antigen-activated sensitized cells.
