CD8+ memory T-cell inflation renders compromised CD4+ T-cell-dependent CD8+ T-cell immunity via naïve T-cell anergy
Whether inflation of CD8+ memory T (mT) cells, which is often derived from repeated prime-boost vaccinations or chronic viral infections in the elderly, would affect late CD8+ T-cell immunity is a long-standing paradox. We have previously established an animal model with mT-cell inflation by transferring ConA-stimulated monoclonal CD8+ T cells derived from Ova-specific T-cell-receptor transgeni...
متن کاملPhenotypic CD8+ T cell diversification occurs before, during, and after the first T cell division.
Effector T cell responses rely on a phenotypically and functionally heterogeneous population of cells. Whether this diversity is programmed before clonal expansion or in later phases as a result of stochastic events or asymmetric cell division is not fully understood. In this study, we first took advantage of a sensitive in vitro assay to analyze the composition of single CD8(+) T cell progenie...
متن کاملPeripheral T-cell Lymphoma of the Uvula: A Rare Entity
Abstract Introduction: Extra-nodal exposition of T-cell non-hodgkin lymphoma (NHL) is extremely rare, and is frequently observed in patients with immune system dysfunction. Peripheral T-cell lymphoma does not express CD56 is rare. Malignant lymphoma of the uvula is exceedingly unusual. The current study reported a case of peripheral T-cell lymphoma of the uvula in an immunecompetent patient. ...
متن کاملCD4 T cell-dependent CD8 T cell maturation.
We have investigated the contribution of CD4 T cells to the optimal priming of functionally robust memory CD8 T cell subsets. Intranasal infection of CD4 T cell-deficient (CD4(-/-)) mice with lymphocytic choriomeningitis virus resulted in the elaboration of virus-specific CD8 T cell responses that cleared the infection. However, by comparison with normal mice, the virus-specific CD8 T cells in ...
متن کاملEvolution of CD8+ T cell responses after acute PARV4 infection.
PARV4 is a small DNA human virus that is strongly associated with hepatitis C virus (HCV) and HIV infections. The immunologic control of acute PARV4 infection has not been previously described. We define the acute onset of PARV4 infection and the characteristics of the acute-phase and memory immune responses to PARV4 in a group of HCV- and HIV-negative, active intravenous drug users. Ninety-eig...
