A new way to control Epstein-Barr virus

A team of researchers at University of Utah Health have shown the Epstein-Barr virus—which causes mononucleosis and is linked to development of several cancers—uses a novel strategy to survive. The virus takes the reins ...

Cells inside cells: the bacteria that live in cancer cells

Cancer cells are comfy havens for bacteria. That conclusion arises from a rigorous study of over 1,000 tumor samples of different human cancers. The study, headed by researchers at the Weizmann Institute of Science, found ...

Study charts the immune landscape of multiple brain cancers

A Ludwig Cancer Research study has profiled, in a sweeping comparative analysis, the distinct immune landscapes of tumors that arise in the brain, or gliomas, and those that metastasize to the organ from the lungs, breast ...

Colorado tool, My-DST, may pick best multiple myeloma treatment

In 1844, multiple myeloma was first treated with a rhubarb pill and an infusion of orange peel. Since then, more than 15 drugs have earned FDA approval to treat multiple myeloma and with so many options, a major question ...

Mapping immune cells in brain tumors

The removal of a malignant brain tumor is something of a balancing act between removing as much tumor tissue as possible at the same time as protecting the healthy tissue. Since cancer cells infiltrate healthy brain tissue, ...

AI could predict risk of lung cancer recurrence

Computer scientists working with pathologists have trained an artificial intelligence (AI) tool to determine which patients with lung cancer have a higher risk of their disease coming back after treatment.

White blood cell

White blood cells (WBCs), or leukocytes (also spelled "leucocytes"), are cells of the immune system defending the body against both infectious disease and foreign materials. Five different and diverse types of leukocytes exist, but they are all produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell. Leukocytes are found throughout the body, including the blood and lymphatic system.

The number of leukocytes in the blood is often an indicator of disease. There are normally between 4×109 and 1.1×1010 white blood cells in a litre of blood, making up approximately 1% of blood in a healthy adult. An increase in the number of leukocytes over the upper limits is called leukocytosis, and in leukopenia, this number is much lower than the lower limit. The physical properties of leukocytes, such as volume, conductivity, and granularity, may change due to activation, the presence of immature cells, or the presence of malignant leukocytes in leukemia.
