The cytotoxicity of peripheral blood leukocytes from normal human donors and from patients with EBV-associated infectious nomonucleosis (IM) has been determined for human lymphoid cell lines (LCL) containing Epstein-Barr virus (EBV) DNA. In a 51Cr release assay, mononuclear leukocytes from all donors are spontaneously cytotoxic. Leukocytes taken from(More)
The onset, duration and magnitude of antibody responses to a poxvirus infection were examined. Mice were inoculated intravenously with the WR strain of vaccinia virus and developed pocks on their tails. The number of pocks was related to the size of the inoculum. Virus was detectable in the spleen and infected mice were subsequently immune to intravenous(More)
Subtle immunodeficiency to infectious agents including measles virus and ten Epstein-Barr virus (EBV) has been described in the X-linked recessive lymphoproliferative syndrome. This syndrome has affected six male cousins and possibly another boy. Three brothers died of an infectious mononucleosis syndrome, in a maternal cousin agammaglobulinemia developed(More)
Investigation of a family with cancer in boys revealed that at least 20 males had the X-linked recessive lymphoproliferative syndrome. A variety of phenotypes occurred: aproliferative phenotypes consisted of aplastic anemia, agranulocytosis or acquired hypogammaglobulinemia; and proliferative phenotypes of B cells included disorders associated with the(More)
Prospective studies demonstrated variable phenotypic expression of the X-linked recessive lymphoproliferative syndrome (X.L.R.L.S.) in three brothers: (1) hypogammaglobulinaemia and subclinical Epstein-Barr-virus (E.B.V.) infection with antibody response to E.B.V.; (2) E.B.V. infection with defective immune response to E.B.V., fatal infectious mononucleosis(More)
Trauma and blood transfusion led to profound, persistent infectious mononucleosis in a 21 year old man. Splenectomy and trauma had apparently produced transient immune deficiency which was complicated by osteomyelitis of a fractured tibia. The transfused blood probably contained Epstein-Barr virus (EBV). Infectious mononucleosis had ensued 25 days after a(More)
DNA synthesis in Epstein-Barr virus (EBV)-infected lymphocytes was inhibited by phosphonoacetic acid (PAA) as measured by [3H]thymidine incorporation. PAA, at a concentration of 200 microgram/ml, inhibited [3H]thymidine incorporation by human umbilical cord lymphocytes infected with EBV strain P94 but had little effect on DNA synthesis in mitogen-stimulated(More)
