Basophil
A leukocyte is a white blood cell. They are part of our bodies' defense system. They are produced in bone marrow, you can find them in blood and lymph system. Usually when WBC … 's or lymphocytes are elevated you have an infection somewhere. Leuk = white Cyte = cell White blood cells. 25 people found this useful. White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All leukocytes are produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell. The number of leukocytes in the blood is often an indicator of disease, and thus the WBC count is an important subset of the complete blood count. The normal white cell count is usually between 4 and 11 × 10 9 /L. In the US this is usually expressed as 4,000–11,000 white blood cells per microliter of blood. A leukocyte is a white blood cell.

Their cytoplasm contains large, coarse, histamine-containing granules that have an affinity for the basic dyes and stain purplish-black. Leukocytes, or white blood cells (WBCs), are the only formed elements that are complete cells, with nuclei and the usual organelles. Accounting for less than 1% of total blood volume, leukocytes are far less numerous than red blood cells. On average, there are 4800-10,800 WBCs/ul of blood Leukocyte adhesion deficiency (LAD) is a rare primary immunodeficiency. The clinical picture is characterized by marked leukocytosis and localized bacterial infections that are difficult to detect until they have progressed to an extensive level secondary to lack of leukocyte recruitment at the site of infection. Thus, patients with this type of leukocyte adhesion deficiency manifest both severe bacterial infections and bleeding disorder. This leukocyte adhesion deficiency variant is associated with defective expression of the Rap-1 activator CalDAG-GEFI. Rap-1 is an essential protein involved in signaling mediated by integrins. Monocytes and neutrophils are phagocytic. The number of leukocytes in the blood is often an indicator of disease, and thus the WBC count is an important subset of the complete blood count. The normal white cell count is usually between 4 and 11 × 10 9 /L. In the US this is usually expressed as 4,000–11,000 white blood cells per microliter of blood. They make up approximately 1% of the total blood volume in a healthy adult. An increase in the number of leukocytes over the upper limits is called leukocytosis, and a decrease below the lower limit is called leukopenia Leukocyte adhesion deficiency type II is extremely rare; only a handful cases have been reported and most of them are of Middle Eastern decent. It is a defect in the expression of ligands for selectins due to lack of enzymes required for expression of selectin ligands. Thus, patients with this type of leukocyte adhesion deficiency manifest both severe bacterial infections and bleeding disorder. This leukocyte adhesion deficiency variant is associated with defective expression of the Rap-1 activator CalDAG-GEFI. Rap-1 is an essential protein involved in signaling mediated by integrins. Nouns denoting body parts. Synonyms: leucocyte; leukocyte; WBC; white blood cell; white blood corpuscle; white cell; white corpuscle. Hypernyms (leukocyte is a kind of...): blood cell; blood corpuscle; corpuscle (either of two types of cells (erythrocytes and leukocytes) and sometimes including platelets). free phagocyte (a phagocyte that circulates in the blood). • LEUKOCYTE (noun). The noun LEUKOCYTE has 1 sense: 1. blood cells that engulf and digest bacteria and fungi; an important part of the body's defense system. Familiarity information: LEUKOCYTE used as a noun is very rare. Human leukocyte antigen (HLA) is a protein – or marker – found on most cells in your body and is used to match you with a donor for your bone marrow or cord blood transplant. The best transplant outcome happens when a patient’s HLA and the donor’s HLA closely match. Human leukocyte antigen (HLA) typing is used to match you with a donor for your bone marrow or cord blood transplant. This is not the same as ABO blood typing. HLA is a protein – or marker – found on most cells in your body. Your immune system uses HLA markers to know which cells belong in your body and which do not.
