Priming of CD8+ T cell responses following immunization with heat-killed Plasmodium sporozoites.

, 2006
Protective immune responses against malaria are induced by immunization with radiation-attenuated Plasmodium sporozoites. In contrast, non-viable, heat-killed sporozoites do not induce protection, emphasizing the requirement for live parasites to achieve

PDK1 regulation of mTOR and hypoxia-inducible factor 1 integrate metabolism and migration of CD8 T cells [PDF]

, 2012
mTORC1 (mammalian target of rapamycin complex 1) controls transcriptional programs that determine CD8 cytolytic T cell (CTL) fate. In some cell systems, mTORC1 couples phosphatidylinositol-3 kinase (PI3K) and Akt to the control of glucose uptake and ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Immunohistochemical analysis of PD-L1, CD4, CD8, CD20, and PU.1 expression in a dedifferentiated chondrosarcoma: the clinical and prognostic value

Alʹmanah Kliničeskoj Mediciny
Background: Dedifferentiated chondrosarcoma (DDCS) is a rare and extremely aggressive variant of mesenchymal bone tumors, with a biphasic structure represented by the classical chondrosarcoma elements, usually of low or intermediate grade, combined with ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

IL-4-secreting CD4+ T cells are crucial to the development of CD8+ T-cell responses against malaria liver stages.

, 2002
CD4+ T cells are crucial to the development of CD8+ T cell responses against hepatocytes infected with malaria parasites. In the absence of CD4+ T cells, CD8+ T cells initiate a seemingly normal differentiation and proliferation during the first few days

Stimulator of interferon genes agonist augmented antitumor immunity of osimertinib in Egfr‐mutated lung cancer

Molecular Oncology, EarlyView.
Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.

CD8+ T-cell responses to Theileria parva are preferentially directed to a single dominant antigen:Implications for parasite strain-specific immunity [PDF]

, 2009
Although immunodominance of CD8(+) T-cell responses is a well-recognised feature of viral infections, its role in responses to more antigenically complex pathogens is less clear.
