Researchers found that lowering MHC I can expose cancerous or foreign cells to CD4+ T cell attack, reshaping assumptions ...

For decades, cancer immunotherapy has focused primarily on CD8 + cytotoxic T lymphocytes as the main executors of tumor cell killing. However, growing clinical and single-cell sequencing evidence ...

Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ultimately lose function during viral infection, findings that could improve ...

Researchers at Karolinska Institutet have identified new properties of CD4-positive T cells in the human intestines and liver ...

New research shows how a specially trained population of immune cells keeps the peace by preventing other immune cells from attacking their own. The study provides a better understanding of immune ...

The brain and spinal cord were once thought to enjoy immune privilege, meaning they were believed to be largely insulated from immune activity elsewhere in the body. In recent years, however, ...

CD4 counts show how strong your immune system is; lower counts mean a weaker immune response. The CD4 percentage shows what part of your white blood cells are CD4 cells and helps check how strong your ...

During infections, the immune system needs to distinguish foreign molecules from invading bacteria and viruses from molecules that are made by cells of the body. If it can’t, the immune system can ...
