Scientists have uncovered new genetic rules that determine whether the immune system’s “killer” T cells remain powerful long-term defenders or become worn out and ineffective. By building a detailed ...

Clonally expanded CD8+ T cells are key drivers of alopecia areata, mediating epithelial cell death and immune infiltration. JAK inhibitors are approved for AA treatment, but recurrence is common, ...

Are you feeling unmotivated to work out regularly during the COVID-19 pandemic? Do you need a fresh source of daily motivation to stick with an exercise regimen involving cardio and strength-training ...

These immune CD8 T cells may provide a target for treating the buildup of fatty lesions in the arteries called atherosclerosis. Atherosclerosis is the underlying pathology of heart attacks and strokes ...

Researchers have found that antigen-specific killer T cells (CD8+ T cells) rapidly expand in the lungs when primed by antigen-presenting lung-resident alveolar macrophages (AMs). This interaction ...

Researchers at the Dallas-based UT Southwestern Simmons Cancer Center report that lactate, a metabolic byproduct produced by cells during strenuous exercise, may rejuvenate immune cells that fight ...

A study in the journal Science Immunology now shows how two subsets of one type of immune cell — the CD8 T cell — develop to provide either short-term or long-term immune protection. The study focuses ...

The ability of immune cells-particularly CD8 + T cells-to launch a rapid burst of proliferation inside tumors is key to the success of modern day cancer immunotherapies. However, the factors and ...

A review found that CD4/CD8 ratio could be used as a prognostic marker for mortality in patients with HIV, though future studies need to be done to confirm these findings. Clinical practices can ...
