White blood cells stainable with neutral stains.
A subgroup of granulocytes defending the body against bacteria. Neutrophils are also known as segs, polys or segmented neutrophils.
special white blood cells that fight infection.
phagocytic granulocyte which engulfs and digests antibodies.
the white blood cells that function in phagocytosis.
Neutrophils phagocytize and kill microorganisms. They also initiate and modify the acute inflammatory process, cause tissue damage and are cytotoxic. Production and storage in the bone marrow, margination of cells in the capillary beds, and the demands of peripheral tissues affect the numbers of circulating neutrophils.
A leukocyte (white blood cell) produced in the bone marrow that circulates in the blood stream. Neutrophils move out of blood vessels into infected tissue in order to attack a foreign substance (bacteria). Normally a serious bacterial infection causes the body to produce an increased number of neutrophils, resulting in a higher white blood cell count. Neutrophils perform their function partially through phagocytosis, a process by which they “eat†other cells and foreign substances. The pus in an abscess is made up of mostly neutrophils.
A type of white blood cell (also known as a polymorphonuclear neutrophils or PMNs). Neutrophils are a type of granulocyte and are a primary defence against bacterial invasion.
The principal phagocyte cell in the blood. This blood cell is the main cell that combats infections.
The most numerous of the granulocytic white cells, they migrate through the bloodstream to the site of infection, where they ingest and destroy bacteria.
White blood cells that protect the body from infection.
White blood cells with a nucleus with three to five lobes connected by slender threads of chromatin, and cytoplasm containing fine inconspicuous granules and stainable by neutral (non-acid/non-basic) dyes. Its name is derived from this last quality. It is both a granulocyte and a phagocyte.
This blood cell is the main cell that combats infections. Often, it is not present in sufficient quantities in patients with acute leukemia or after chemotherapy, which increases their susceptibility to infection.
White blood cells that fight bacterial infection.
A type of white blood cell and one of the first immune cells to arrive during the acute inflammatory response to a spinal cord injury. Neutrophils manufacture enzymes, which help kill bacteria; but in the brain and spinal cord they are lethal to nerve cells.
A mature white blood cell that fights bacterial infections. Neutrophils are also called segmented neutrophils or segs.
A mobile cell made in large numbers in the bone marrow and released into the blood. They can be recruited into the lungs and other tissues by specific substances released at sites of inflammation to help to protect against infections. Neutrophils are capable of releasing large amounts of destructive enzymes that can damage the interstitium and cells of the tissue, especially when levels of alpha-1 antitrypsin are very low. In the lungs, this process can lead to emphysema. Smoking results in increased recruitment of neutrophils and other molecular events that damage the tissue and result in emphysema. However, neutrophils represent a "double-edged sword" because they are vital to the normal host defense mechanisms.
A type of white blood cell that plays a major role in the body's defense against bacteria, viruses, and fungi.
Also called polymorphonuclear leukocytes because they are white blood cells with a multi-lobed nucleus. Neutrophils combat infection by internalizing and destroying disease causing organisms such as bacteria.
Type of white blood cell filled with enzymes used to kill and digest micro-organisms.
White blood cells that have a multi-lobed nucleus and are active against bacteria, stain with neutral dyes
The primary type of white blood cells found in the body.
Polymorphonuclear granulocytes, which form the major population of blood leucocytes.
The larger and physiologically most numerous class of infection-fighting white blood cells, characteristically even more numerous in generalised bacterial infections.
