Cell signaling and cytotoxicity by peroxynitrite. [PDF]

Environmental Health Perspectives, 2002
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 ...

Cytotoxic Efficiency of Human CD8+ T Cell Memory Subtypes

Frontiers in Immunology, 2022
Immunological memory is important to protect humans against recurring diseases. Memory CD8+ T cells are required for quick expansion into effector cells but also provide immediate cytotoxicity against their targets. Whereas many functions of the two main

Lysis mediated by T cells and restricted by H-2 antigen of target cells infected with vaccinia virus [PDF]

, 1975
VARIOUS virus infections lead to the formation of cytotoxic lymphocytes (CL), which are capable of killing virus-infected target cells1−4. Specific lysis of target cells infected with 51Cr-labelled vaccinia virus could be observed when investigating the ...

The effect of SMAD4 on the prognosis and immune response in hypopharyngeal carcinoma

Frontiers in Medicine, 2023
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.

Shared determinants between virus-infected and trinitrophenyl-conjugated H-2-identical target cells detected in cell-mediated lympholysis [PDF]

, 1976
Infection of H-2-identical mice with either lymphocytic choriomeningitis (LCM) virus, vaccinia virus, or paramyxo (Sendai) virus resulted in the generation of specifically sensitized cytotoxic T lymphocytes (CTL).

Selective inhibition of T suppressor-cell function by a monosaccharide [PDF]

, 1981
Interactions between regulatory T lymphocytes and other cells are assumed to occur at the level of the cell surface. T cells which suppress the generation of specifically effector cells have been described as having antigenic, idiotypic, allotypic and I ...

Tailoring CD19xCD3-DART exposure enhances T-cells to eradication of B-cell neoplasms. [PDF]

, 2018
Many patients with B-cell malignancies can be successfully treated, although tumor eradication is rarely achieved. T-cell-directed killing of tumor cells using engineered T-cells or bispecific antibodies is a promising approach for the treatment of ...

Autophagy induced macrophages by α-alumina(α-AL2O3) conjugated cysteine peptidase, enhances the cytotoxic activity of CD8+ T lymphocytes against Leishmania major [PDF]

BioImpacts, 2023
Introduction: Induction of a protective immune response against Leishmania major requires the activation of both TH1 and CD8+ T lymphocytes. Because L. major is an intra-phagosomal parasite, its antigens do not have access to MHC-I.

CD8+ T-cell responses in vaccination: Reconsidering targets and function in the context of chronic antigen stimulation [PDF]

, 2018
Cytotoxic CD8 T cells play important roles in eliminating infected and transformed cells. Owing to their potential for therapeutic applications, significant efforts are dedicated toward developing CD8 T cell-based vaccines.

Fusion of Sendai virus with the target cell membrane is required for T cell cytotoxicity [PDF]

, 1978
INFECTION of mice with viruses can generate cytotoxic T lymphocytes (CTL) which show restricted specificity for target cell lysis. Specific lysis requires that the virus used to prime the target cells must be of the same type as that used to sensitise ...
