Epstein-Barr virus-specific antibody-dependent cellular cytotoxicity in patients with Burkitt's lymphoma.
Coded sera from 54 patients with African Burkitt's lymphoma (BL) were titrated for antibodies against an Epstein-Barr virus (EBV)-induced membrane antigen in the antibody-dependent cellular cytotoxicity (ADCC) assay. The titers were then correlated with the progression of lymphoma growth following chemotherapy. In 74% of the patients with high ADCC titers (greater than 3,840), lymphomas showed ...
متن کاملEpstein–Barr Virus-Specific Immune Control by Innate Lymphocytes
Epstein-Barr virus (EBV) is a potent B cell transforming pathogen in humans. In most persistently EBV-infected individuals, potent cytotoxic lymphocyte responses prevent EBV-associated pathologies. In addition to comprehensive adaptive T cell responses, several innate lymphocyte populations seem to target different stages of EBV infection and are compromised in primary immunodeficiencies that r...
متن کاملTonsillar homing of Epstein-Barr virus-specific CD8+ T cells and the virus-host balance.
Patients with infectious mononucleosis (IM) undergoing primary EBV infection show large expansions of EBV-specific CD8+ T cells in the blood. While latent infection of the B cell pool is quickly controlled, virus shedding from lytically infected cells in the oropharynx remains high for several months. We therefore studied how responses localize to the tonsil, a major target site for EBV, during...
متن کاملEpstein-Barr Virus Transformation Induces B Lymphocytes
Interleukin 10 (I1.10) is a pleiotropic factor that enhances proliferation of activated human B lymphocytes and induces them to secrete high amounts of immunoglobulins. Here we show that several human B cell lines were able to constitutively secrete human (h)Ibl0. Whereas none of the pre-B nor the plasmocytic cell lines tested produced hi1-10, 25 of the 36 tested mature B cell lines (lymphoblas...
متن کاملEpstein-Barr virus-infected T lymphocytes in Epstein-Barr virus-associated hemophagocytic syndrome.
The clonal composition of EBV-infected cells was examined in three cases of EBV-associated hemophagocytic syndrome by analysis of the heterogeneity of terminal repetitive sequences in the EBV genome, indicating monoclonal expansion of EBV-infected cells in all cases. Involvement of T lymphoid cells was determined by in situ hybridization using 35S-labeled RNA probes specific for the small EBV-e...
