Human Immature Thymocytes as Target Cells of the Leukemogenic Activity

نویسنده

چکیده

The risk of developing adult T-cell leukemia (ATL) associated with neonatal infection by human T-cell leukemia virus type I (HTLV-I) suggests that early events triggered by HTLV-I might be of crucial importance in initiating the multistep lymphoproliferative process leading several decades later to the development of leukemic disease. Thus, infection of thymocytes early in life might be directly correlated with the development of ATL. In the present study, we show that in vitro infection of mature {CD2+CD3’) or immature (CD2+CD3-) thymocytes resulted in the exogenous interleukin (lL)-2-dependent proliferation of HTLV-l-positive thymocytes, most of them displaying a CD2+CD3-CD4+ phenotype and expressing the CD25 molecule, the a chain of the

Regulation of pT alpha gene expression by a dosage of E2A, HEB, and SCL.

The expression of the pT alpha gene is required for effective selection, proliferation, and survival of beta T-cell receptor (beta TCR)-expressing immature thymocytes. Here, we have identified two phylogenetically conserved E-boxes within the pT alpha enhancer sequence that are required for optimal enhancer activity and for its stage-specific activity in immature T cells. We have shown that the...

Immature CD4+CD8+ Thymocytes Are Preferentially Infected by Measles Virus in Human Thymic Organ Cultures

Cells of the human immune system are important target cells for measles virus (MeV) infection and infection of these cells may contribute to the immunologic abnormalities and immune suppression that characterize measles. The thymus is the site for production of naïve T lymphocytes and is infected during measles. To determine which populations of thymocytes are susceptible to MeV infection and w...

Expression of CD21 is developmentally regulated during thymic maturation of human T lymphocytes.

CD21, the C3d/CD23/Epstein-Barr virus (EBV), receptor is expressed at low density on cells of the T lineage. Immature thymocytes express CD21 with high density. In the present study, we have analyzed the expression of CD21 during intrathymic maturation of T cells. An intense staining for CD21 was observed at the double-negative stage and at the stage of early acquisition of CD4. CD21 expression...
