Antimetastatic defense by CD8+ T cells
Trends in Cancer, 2022Metastasis is an intricate process whereby tumor cells migrate from the primary tumor, survive in the circulation, seed distal organs, and proliferate to create metastatic foci. CD8+ T cells can detect and eliminate tumor cells. Research on CD8+ T cell–dependent antitumor immunity has classically focused on its role in the primary tumor.

Current Opinion in Immunology, 2005
Mounting evidence shows that CD8(+) T cells contribute to the initiation, progression and regulation of several pathogenic autoimmune responses in which these cells were not previously thought to play a major role. CD8(+) T cells can kill target cells directly, by recognizing peptide-MHC complexes on target cells, or indirectly, by secreting cytokines ...

This chapter focuses on CD8 T cells, with an emphasis on the major histocompatibility complex (MHC) Ia-restricted T cells in tuberculosis, and also touches upon the unconventional CD8 T cells restricted by β2m-associated nonclassical MHC Ib or MHC I-like molecules. Although the T cells which recognize mycobacterial glycolipids in the context of group I

This review describes what is generally known about CD8 immune responses, and focus in the most recent advances in this domain. It also attempts to point to the areas where experimental evidence is contradictory or insufficient, and thus require further exploration and clarification.

Critical Reviews in Immunology, 2003
Aging of the immune system, or "immunosenescence," is associated with both a marked reduction in responsiveness as well as functional dysregulation. These changes have been implicated in the increased morbidity and mortality of the elderly population from infectious disease, and may also play a role in autoimmunity and cancer.

Antigen‐presenting Cells for CD8+ T Cells
Immunological Reviews, 1990Evidence is presented that a wide variety of cell types are capable of presenting class I alloantigens to purified unprimed CD8+ cells in the absence of added help. These cells include dendritic cells, a population of Ia- Thy 1- cells in spleen, peritoneal exudate cells and one of three T-tumor lines. Some cell types, e.g.

Current Opinion in Immunology, 1994
Recent experiments show that laboratory mice infected once with an influenza A virus or with the murine parainfluenza type 1 virus, called the Sendai virus, have enhanced numbers of cytotoxic T-lymphocyte precursors ( > 20x background) for life. Neither virus persists at the genome level, and the mice are maintained under conditions where there is no ...

CD8+ T cells are important for the protective immunity against intracellular pathogens and tumor. In the case of chronic infection or cancer, CD8+ T cells are exposed to persistent antigen and/or inflammatory signals. This excessive amount of signals often leads CD8+ T cells to gradual deterioration of T cell function, a state called "exhaustion ...

The path of the T-bet-ian CD8+ T cells
Nature Immunology, 2021The eradication of pathogens and establishment of immunological memory depend on the generation of both effector and long-lived memory cells within specialized immune niches. Whole-organ imaging demonstrates that, during viral infection, the fate of CD8+ T cells in lymph nodes is coupled to chemotactic signals controlling their distribution within ...
