title: Impairment of rosette-forming T lymphocytes in patients with primary intracranial tumors.
abstract: The percentage of T lymphocytes that form rosettes (RFC) with sheep erythrocytes (E rosettes), cutaneous delayed-type hypersensitivity, and in vitro lymphocyte transformation was measured in 15 patients with primary intracranial tumors. The ability of T lymphocytes  to  form E rosettes was significantly impaired. These patients also exhibited impaired ability to become sensitized to dinitrochlorobenzene and humoral suppression of PHA-induced lymphocyte blastogenesis. The hypothetical role of antibody(s) to possible shared antigenic determinants on brain and T cells is discussed.
