We previously demonstrated that Thy1.2+, CD4+, Ia-T cells are responsible for transfer of murine adoptive experimental hypersensitivity pneumonitis (adoptive EHP). To characterize the culture conditions necessary for development of these cells, we depleted cell cultures of Thy1.2+, CD4+, CD8+, or Ia+ cells using MoAbs and complement or magnetic beads, prior to culture of sensitized C3H/HeJ murine spleen cells (SC) with Micropolyspora faeni. After culture, cells were transferred to recipients which were later challenged intratracheally with M. faeni. The extent of pulmonary inflammatory changes in these animals was determined 4 days after intratracheal (i.t.) challenge with M. faeni. Cultured M. faeni-sensitized SC which had been treated before culture with media, complement only, anti-CD8 plus complement or magnetic beads alone could transfer EHP to naive animals. SC treated with anti-Thy1.2 or anti-CD4 plus complement could not transfer EHP. Treatment of SC with anti-Iak plus magnetic beads diminished the ability of cultured cells to transfer EHP. We conclude that the ability to produce cells able to adoptively transfer EPH is dependent on the presence of Thy1.2+, CD4+, and Ia+ cells, but not CD8+ cells, at the onset of culture.
