A 10.8-kDa member of the S-100 family of calcium-binding proteins that can form homo- or heterocomplexes with CALGRANULIN B and a variety of other proteins. The calgranulin A/B heterodimer is known as LEUKOCYTE L1 ANTIGEN COMPLEX. Calgranulin A is found in many cell types including GRANULOCYTES; KERATINOCYTES; and myelomonocytes, and has been shown to act as a chemotactic substance for NEUTROPHILS. Because it is present in acute inflammation but absent in chronic inflammation, it is a useful biological marker for a number of pathological conditions.
Eicosatetraenoic acids substituted in any position by one or more hydroxy groups. They are important intermediates in a series of biosynthetic processes leading from arachidonic acid to a number of biologically active compounds such as prostaglandins, thromboxanes, and leukotrienes.
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.
The complex formed by the binding of antigen and antibody molecules. The deposition of large antigen-antibody complexes leading to tissue damage causes IMMUNE COMPLEX DISEASES.
Rare, autosomal recessive disorder caused by deficiency of the beta 2 integrin receptors (RECEPTORS, LEUKOCYTE-ADHESION) comprising the CD11/CD18 family of glycoproteins. The syndrome is characterized by abnormal adhesion-dependent functions, especially defective tissue emigration of neutrophils, leading to recurrent infection.
Molecules found on the surface of some, but not all, B-lymphocytes, T-lymphocytes, and macrophages, which recognize and combine with the Fc (crystallizable) portion of immunoglobulin molecules.
An enzyme that catalyzes the oxidation of arachidonic acid to yield 5-hydroperoxyarachidonate (5-HPETE) which is rapidly converted by a peroxidase to 5-hydroxy-6,8,11,14-eicosatetraenoate (5-HETE). The 5-hydroperoxides are preferentially formed in leukocytes.
The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B.
An integrin heterodimer widely expressed on cells of hematopoietic origin. CD11A ANTIGEN comprises the alpha chain and the CD18 antigen (ANTIGENS, CD18) the beta chain. Lymphocyte function-associated antigen-1 is a major receptor of T-CELLS; B-CELLS; and GRANULOCYTES. It mediates the leukocyte adhesion reactions underlying cytolytic conjugate formation, helper T-cell interactions, and antibody-dependent killing by NATURAL KILLER CELLS and granulocytes. Intracellular adhesion molecule-1 has been defined as a ligand for lymphocyte function-associated antigen-1.

Filamentous proteins that are the main constituent of the thin filaments of muscle fibers. The filaments (known also as filamentous or F-actin) can be dissociated into their globular subunits; each subunit is composed of a single polypeptide 375 amino acids long. This is known as globular or G-actin. In conjunction with MYOSINS, actin is responsible for the contraction and relaxation of muscle.
Small cationic peptides that are an important component, in most species, of early innate and induced defenses against invading microbes. In animals they are found on mucosal surfaces, within phagocytic granules, and on the surface of the body. They are also found in insects and plants. Among others, this group includes the DEFENSINS, protegrins, tachyplesins, and thionins. They displace DIVALENT CATIONS from phosphate groups of MEMBRANE LIPIDS leading to disruption of the membrane.
Transmembrane proteins consisting of a lectin-like domain, an epidermal growth factor-like domain, and a variable number of domains that are homologous to complement regulatory proteins. They are important cell adhesion molecules which help LEUKOCYTES attach to VASCULAR ENDOTHELIUM.

Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the ANTIGEN (or a very similar shape) that induced their synthesis in cells of the lymphoid series (especially PLASMA CELLS).
The property of blood capillary ENDOTHELIUM that allows for the selective exchange of substances between the blood and surrounding tissues and through membranous barriers such as the BLOOD-AIR BARRIER; BLOOD-AQUEOUS BARRIER; BLOOD-BRAIN BARRIER; BLOOD-NERVE BARRIER; BLOOD-RETINAL BARRIER; and BLOOD-TESTIS BARRIER. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (TIGHT JUNCTIONS) which may limit large molecule movement.

  • Neutrophils, the most abundant granulocytes, are essential for host innate immune defense. (
  • Granulocytes (neutrophils) are leukocytes with granules in their cytoplasm that contain destructive chemicals. (
  • Neutrophil granulocytes, more commonly known as neutrophils, are the most common type of white blood cells found in human beings. (
  • Granulocytes , including neutrophils , are distinguished from the other category of leucocytes - which are called agranulocytes , because granulocytes contain chemical-filled cytoplasmic vesicles called granules . (
  • Neutrophils are phagocytic granulocytes that spend most of their lives circulating in peripheral blood. (
  • Granulocytes are further enriched via density gradient centrifugation and processed to remove remaining red blood cells. (
  • Along with neutrophils, eosinophils are included in the WBC group called the granulocytes. (
  • The granulocytes, which have granules in the cytoplasm are the neutrophil, the basophil and the eosiniphil. (
  • The next three types of white blood cells are referred to as granulocytes since they all contain rough, grain-like particles that assist in attacking viruses and bacteria . (
  • Neutrophils (also known as neutrocytes or heterophils ) are the most abundant type of granulocytes and make up 40% to 70% of all white blood cells in humans. (
  • When adhered to a surface, neutrophil granulocytes have an average diameter of 12-15 micrometers (µm) in peripheral blood smears . (
  • The effect of maximal exercise on the activity of neutrophil granulocytes in highly trained athletes in a moderate training period by: Hack, V., et al. (

  • Accumulation, activation, and control of neutrophils at inflammation sites is partly driven by N-formyl peptide chemoattractant receptors (FPRs). (
  • NLR might have prognostic significance of diseases related to chronic low-grade inflammation and can be easily obtained from the differential white blood cell count [ 9 ]. (
  • Introduction Excessive neutrophilic airways inflammation is the central feature of bronchiectasis but little is known about the role of serum neutrophils in bronchiectasis. (
  • Recent investigations suggest that neutrophils may play an important role in the late-phase allergen-induced inflammation in allergic airway diseases. (
  • These data agree with previous studies showing that S. flexneri induces tissue inflammation and chemotactic cues for neutrophil recruitment, whereas M. marinum largely avoids neutrophil recruitment. (
  • A positive correlation between CRP and the percentages of neutrophils exhibiting toxic granulation during inflammation has been demonstrated, and that the fluctuations of CRP and toxic granulation of neutrophils were similar. (
  • We studied whether grading of toxic granulated neutrophils can be used as a surrogate marker for infection or inflammation, and also be an easier method than previously described methods. (
  • The proposed system can be applied to patients with inflammatory or infectious conditions, where grading of toxic granulation of neutrophils can possibly be used as a surrogate marker to assess infection or inflammation and their response to treatment. (
  • 5.Serum derived from acute inflammation was decreased apoptosis of neutrophils. (

  • Total white blood cell (WBC) count is an indicator for acute or chronic inflammation, and an elevated WBC count also is a risk factor for atherosclerotic vascular disease. (
  • Here, we demonstrate that in the acute inflammatory response during endotoxemia , aged neutrophils cease returning to the bone marrow and instead rapidly migrate to the site of inflammation . (
  • In healthy adults, neutrophils circulate in a quiescent state in the bloodstream until being recruited to sites of inflammation or infection. (
  • We investigated whether deficiency of neonatal neutrophil function in vitro was evident in acute pulmonary inflammation. (
  • In addition, we have evaluated the effect of hFbg on two functional events related to expression and resolution of inflammation: cytotoxic capacity and rate of neutrophil apoptosis. (
  • Scientists have shown for the first time that platelets, the cells needed for blood clotting, help white blood cells called neutrophils fight inflammation. (
  • These white blood cells circulate in the bloodstream awaiting chemical signals of invasion and inflammation. (
  • Neutrophils are the so-called cleaning cells, since they are the first cells to migrate to a place with an infection and inflammation to destroy the pathogens. (
  • By observing how fast the red blood cells in the sample fall, health professionals can determine the extent of inflammation in the body. (
  • Infection and inflammation result in increased neutrophil production. (
  • Other inflammatory changes including leucocytosis, toxic granules, Döhle bodies and neutrophil vacuolation may also be seen in patients showing "shift to left" because of infection/inflammation. (
  • Although the neutrophil recruitment cascade during inflammation has been well described, the molecular players that halt neutrophil chemotaxis remain unclear. (
  • Neutrophils are involved in inflammation through leukotriene (LT) production. (
  • The predominant proinflammatory leukotriene released from neutrophils is LTB4, which serves as a biological marker of inflammation. (
  • Researchers at Lund University have uncovered that the activation of neutrophils - a type of white blood cells - leads to inflammation in the pancreas which results in the development of acute pancreatitis. (
  • Neutrophil webs have been studied in other areas as well, including inflammation of the liver , lungs, rheumatic disease (lupus) and other inflammatory diseases. (
  • The neutrophil blood test forms part of the differential white blood cell count which also measures other white blood cells like lymphocytes, monocytes and basophils. (
  • Laboratory tests showed a total bilirubin level of 764.7 µmol/L (44.7 mg/dL) and direct bilirubin of 37 µmol/L. Hemoglobin was 178 g/L, white cell count 26.1 × 10 9 /L, neutrophils 16.1 × 10 9 /L, lymphocytes 5.8 × 10 9 /L, and monocytes 3.0 × 10 9 /L. There was no blood group incompatibility with mother. (
  • As compared with the data from healthy children, the relative neutrophil count of all children with KD was increased, and that of lymphocytes was decreased. (
  • The altered levels of neutrophils and lymphocytes were found to be linearly correlated. (
  • Unlike clinical infections, subclinical infections are identified by infiltration of tissue by neutrophils, macrophages, and lymphocytes without overt findings of clinical infection. (
  • Previous studies suggest that neutrophils, reflecting activation of the innate immune system, are more strongly associated with incidence of coronary heart disease (CHD) than lymphocytes, which reflect activation of the adaptive immune system. (
  • Another 174 subjects were excluded because of missing data on lymphocytes, neutrophils, body mass index, waist, systolic blood pressure or diastolic blood pressure. (

  • Subsets of peripheral blood lymphocytes were analysed in 31 patients. (
  • On the other hand, systemic inflammatory response to tumours causes changes in the haematological components like white blood cells, specifically the neutrophils, lymphocytes and monocytes. (
  • The neutrophils in the spleen are located around B lymphocytes to help their activation and offer a first rapid response when there are pathogens. (
  • through several different experimental approaches we have proven that neutrophils in the spleen acquire the ability to interact with B cells or B lymphocytes, inducing the production of antibodies, a role that lymphocytes circulating in blood are not able to do " states Irene Puga, researcher of the IMIM and a signatory of this article. (
  • This work opens the door to therapies which are geared at, and more affective against, different pathogens, for example, to develop vaccines to increase the capacity of neutrophils in the spleen so as to have an incidence on the production of antibodies by type B lymphocytes. (
  • Most white blood cells are neutrophils or lymphocytes . (
  • Lymphocytes are round white blood cells a bit bigger than a red blood cell . (
  • As you know, the population of leukocytes is heterogeneous and includes our neutrophils, as well as lymphocytes, monocytes, eosinophils and basophils. (
  • Their number in the blood increases, and the content of segmented lymphocytes decreases. (
  • Neutrophils are involved in cellular defence (phagocytosis) of small pathogenic microorganisms. (
  • Freshly isolated peripheral neutrophils from the groups were treated with LXA4 or vehicle control and we assessed spontaneous neutrophil apoptosis at 20 hours, neutrophil activation, neutrophil degranulation, phagocytosis of GFP labelled Pseudomonas aeruginosa and expression of LXA4 receptor formyl peptide receptor (FPR)2. (
  • There was significant improvement in neutrophil phagocytosis of GFP labelled Pseudomonas aeruginosa in a dose dependent manner in all three groups. (
  • The pro-resolving mediator LXA4 stabilised the neutrophil whilst promoting neutrophil phagocytosis. (
  • To evaluate neutrophil chemotaxis, phagocytosis, and reactive oxygen species (ROS) production in patients with allergic asthma and rhinitis challenged with inhaled D. pteronyssinus. (
  • For chemotaxis analysis neutrophils were stimulated with interleukin-8, and for ROS analysis as well as for phagocytosis cells were stimulated with S. aureus bacteria. (
  • After challenge, neutrophil chemotaxis and phagocytosis increased after 7 h and 24 h, when ROS production - only after 24 h. (
  • Flow cytometry was used to assess the phagocytosis of fluorescent-labelled bacteria by equine peripheral blood neutrophils and pulmonary alveolar macrophages. (
  • We have found that activation of neutrophils by hFbg resulted in both enhancement of phagocytosis and Ab-dependent cellular cytotoxicity, and delay of apoptosis. (
  • Phagocytosis is the primary function of neutrophils, and they are highly effective and efficient at performing this role. (
  • While eosinophils are not as effective at phagocytosis as neutrophils are, they have other immune system defense functions -- including participation in allergic responses and defending the body against parasites, such as intestinal worms. (
  • Monocytes, like neutrophils, can perform phagocytosis. (
  • Neutrophil granulocyte migrates from the blood vessel to the matrix, secreting proteolytic enzymes, in order to dissolve intercellular connections (to the improvement of its mobility) and envelop bacteria through phagocytosis. (
  • Similar results were obtained when phorbol myristate acetate was employed as nonphagocytic soluble stimulus, suggesting that the capacity of neutrophils to degranulate MPO rather than phagocytosis was enhanced following exercise. (
  • 2. As a part of the estimation of total white blood cell count in other inflammatory conditions. (
  • In this work, we describe a handheld microfluidic device that discriminates asthma from allergic rhinitis patients based on neutrophil function-an inflammatory cell that has been implicated in the pathogenesis of asthma. (
  • Many cell types, including peripheral blood neutrophils, produce IL-8 that can be released by a variety of pro-inflammatory stimuli. (
  • The aim was to analyze the variations in several immune functions and oxidative-inflammatory stress and damage parameters in both isolated peripheral neutrophils and mononuclear blood cells, as well as in whole blood cells, from patients diagnosed with mild (mAD) and severe AD, and of age-matched controls (elderly healthy subjects) as well as of adult controls. (
  • This impairment of immune functions could be mediated by: (1) the higher oxidative stress and damage also observed in blood cells from mAD and AD patients and in isolated neutrophils [lower glutathione (GSH) levels, high oxidized glutathione (GSSG)/GSH ratio, and GSSG and malondialdehyde contents], and (2) the higher release of basal pro-inflammatory cytokines (IL-6 and TNF-α) found in AD patients. (
  • In particular, infection models can benefit from zebrafish lines with fluorescently-tagged immune cells that enable the in vivo imaging of leukocytes (white blood cells: macrophages, neutrophils) and their role in inflammatory and infectious disease. (
  • Aged neutrophils contribute to the first line of defense in the acute inflammatory response. (
  • This distinct behavior of aged neutrophils under inflammatory conditions is dependent on specific age-related changes in their molecular repertoire that enable these "experienced" immune cells to instantly translate inflammatory signals into immune responses. (
  • In particular, aged neutrophils engage Toll-like receptor -4- and p38 MAPK -dependent pathways to induce conformational changes in ß2 integrins that allow these phagocytes to effectively accomplish their mission in the front line of the inflammatory response. (
  • Galectin-3, an endogenous β-galactoside-binding lectin, is emerging as an inflammatory mediator and we have previously shown that primed/activated, but not resting, adult neutrophils respond to this lectin by production of reactive oxygen species (ROS). (
  • Upon exposure to the inflammatory stimuli that are associated with labor, the neutrophils develop a reactive phenotype with extensive priming features. (
  • These data suggest that the lack of blood flow diversion from inflamed neonatal lung increases neutrophil migration into alveoli, allowing for preservation of an inflammatory response despite neutrophil deficiencies in chemotaxis. (
  • Spent neutrophils subsequently undergo apoptosis and are cleared by macrophages, thereby resolving the inflammatory episode. (
  • In parallel, neutrophil activation is thought to play a crucial role in several inflammatory conditions, and it has been recently demonstrated that Fbg specifically binds to the α-subunit of CD11b/CD18 on neutrophil surface. (
  • We conclude that during inflammatory processes, soluble Fbg could influence neutrophil responses, increasing and prolonging their functional capacity. (
  • Once stimulated by a sequence of inflammatory events, neutrophils are one of the first of the inflammatory cells to migrate to areas of infection or tissue injury where they engulf bacteria, other microorganisms, and microscopic particles. (
  • Overall, lactose promoted a regulatory cytokine milieu in the pancreas and reduced infiltration of inflammatory neutrophils and macrophages. (
  • This pattern, characteristic in the presence of an infectious-inflammatory process, is called the neutrophil shift to the left. (
  • Pus in the wound, intoxication and inflammatory syndrome - the results of the fight of neutrophils with a foreign agent. (
  • In this issue of Blood , Bartels and colleagues demonstrate that acetylation of the transcription factor CCAAT enhancer binding protein ε (C/EBPε) is essential for terminal neutrophil granulocyte differentiation. (
  • 2 Prophylactic use of granulocyte colony-stimulating factor (G-CSF) reduces mortality by increasing neutrophil numbers. (
  • 3 C/EBPβ-deficient mice display normal granulocyte differentiation and steady-state levels of neutrophils but are unable to produce neutrophils in response to cytokine exposure or infection during "emergency" granulopoiesis. (
  • We show that under basal conditions granulocyte colony-stimulating factor (G-CSF) is an essential regulator of neutrophil release from the bone marrow. (
  • The detection of neutrophil antibodies requires specialist testing such as the granulocyte agglutination test (GAT) (3), granulocyte immunofluorescence test (GIFT) (3) and HNA typing. (
  • Here, we use real time fluorescence microscopy to image transgenic zebrafish larvae with neutrophils (granulocyte white blood cells) expressing the green fluorescent protein eGFP. (
  • Being the first line of defence, the innate immune response and thus the neutrophil granulocyte is of outmost importance for the neonatal protection against infection. (
  • Effect of granulocyte colony-stimulating factor on the rate of neutrophil engraftment following peripheral-blood stem-cell transplantation. (
  • This is the most common granulocyte, accounting for more than half of the total amount of white blood cells. (
  • Chronic neutropenia often accompanies HIV infection, the result of impaired production of neutrophils and accelerated destruction of neutrophils by antibodies (see Ch. 145). (
  • Numbers of neutrophils can go down after or during a viral infection because many of the neutrophils leave the blood to fight the infection in the tissues and so normal blood values are reduced. (
  • In a viral infection, the role of the neutrophils is mostly to clean up the cellular debris, AFAIK. (
  • Blood transfusion is associated with an increased risk of organ damage, infection, and alloimmunity. (
  • Neutrophil directional migration in response to chemical gradients, also known as chemotaxis, is one of the key phenomena in the immune responses against bacterial infection. (
