title: A comparison of murine hepatic accessory cells and splenic dendritic cells.
abstract: Accessory cells are required for proliferation and antibody synthesis of B lymphocytes and proliferation of T lymphocytes in primary immune responses in vitro. The obligatory cells derived from the spleen are referred to as dendritic cells. Accessory cells were isolated from normal adult livers which were functionally interchangeable with splenic DC. Both hepatic accessory cells (AC) and splenic DC adhere firmly to plastic culture dishes or wells within 2 hr; but hepatic AC, unlike splenic DC, do not detach during 22 hr additional incubation. Hepatic AC, unlike splenic DC, are not lysed or inactivated by monoclonal antibody 33D1 and C'. Hepatic AC and splenic DC are similarly sensitive to irradiation in vivo and insensitive to irradiation in vitro. Hepatic AC are separated with cells which are predominantly phagocytic and FcR+ and contain nonspecific esterase. Both hepatic AC and splenic DC are suppressed or eliminated by activation of NK cells in vivo, a phenomenon prevented by prior elimination of NK cells.
