Sleep is known to play a key role in facilitating various physiological processes, while also contributing to the healthy functioning of the brain. Lack of sleep and poor sleep quality have been linked to various chronic ...
Medical investigators are theorizing that a combination of two treatments that activate myeloid cells may effectively treat a recalcitrant form of pancreatic cancer that thwarts conventional immunotherapy.
One of the more rigorous debates in immunology has centered on the origin of an enigmatic T cell population that possesses properties imparting memory and stem cell–like qualities, but facts about their genesis were so ...
In a paper, "Epitope editing enables targeted immunotherapy of acute myeloid leukaemia," published in Nature, researchers at the Department of Pediatric Oncology, Dana-Farber Cancer Institute, Boston, introduce a genetic ...
There's no question that tumor cells are notoriously skilled masters of immune disguise and, in many ways, real-life versions of what it's like hiding under the fictional invisibility cloak highlighted in the Harry Potter ...
Our immune system has an ingenious trick up its sleeve. It remembers past foes, stopping potential sickness in its tracks through a phenomenon known as immunological memory. This is thanks to specialized cells—tissue-resident ...

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.
