CD4+ T cells are required to sustain CD8+ cytotoxic T-cell responses during chronic viral infection
In this study, we have examined the relative contributions of CD4+ and CD8+ T cells in controlling an acute or chronic lymphocytic choriomeningitis virus (LCMV) infection.

The role of cytotoxic T cells [PDF]
The development of anti-HIV T cell-based vaccines is a current major objective in the strategy to halt AIDS pandemic. For this purpose the understanding of the mechanisms underlying effective HIV-specific CD8+ T cell responses is of great importance. One of the most appealing models for such efficient responses is found today in HIV controllers (HICs),

Fighting viral infections and virus-driven tumors with cytotoxic CD4+ T cells [PDF]
CD4+ T cells have been and are still largely regarded as the orchestrators of immune responses, being able to differentiate into distinct T helper cell populations based on differentiation signals, transcription factor expression, cytokine secretion, and

Generation of virus-specific cytotoxic T cells in vitro II. Induction requirements with functionally inactivated virus preparations [PDF]
Using noninfectious Sendai virus preparations after selective enzymatic digestion of either of the two viral envelope glycoproteins, it was possible to study the effect of different virion-cell membrane interactions on virus-specific cytotoxic T ...

Cell signaling and cytotoxicity by peroxynitrite. [PDF]
Reactive nitrogen species are now considered to play an important role in various pathologies. Although the pathological significance of these molecules, peroxynitrite in particular, has long been attributed to their abilities to react with any component of the cells, including lipids, proteins, and DNA, a paradigm shift has recently been occurring ...

The effect of SMAD4 on the prognosis and immune response in hypopharyngeal carcinoma
ObjectivesIn malignant tumors, elevated infiltration of intratumoral CD8+ cytotoxic T cells predicts a beneficial prognosis, whereas high levels of CD15+ neutrophils in peritumor tissues indicate poor prognosis.

Generation of virus-specific cytotoxic T cells in vitro I. Induction conditions of primary and secondary Sendai virus-specific cytotoxic T cells [PDF]
H-2-restricted cytotoxic T cells specific for Sendai virus were generated in vitro in a primary response from normal mouse lymphocytes cultured in the presence of infective as well as inactivated Sendai virus. Antigen-presenting cells of different origin,

CD4 Helper and CD8 Cytotoxic T Cell Differentiation.
A fundamental question in developmental immunology is how bipotential thymocyte precursors generate both CD4+ helper and CD8+ cytotoxic T cell lineages. The MHC specificity of αβ T cell receptors (TCRs) on precursors is closely correlated with cell fate ...
