Macrophages
The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS. (from The Dictionary of Cell Biology, Lackie and Dow, 3rd ed.)
Superoxides
Highly reactive compounds produced when oxygen is reduced by a single electron. In biological systems, they may be generated during the normal catalytic function of a number of enzymes and during the oxidation of hemoglobin to METHEMOGLOBIN. In living organisms, SUPEROXIDE DISMUTASE protects the cell from the deleterious effects of superoxides.
Latex
A milky, product excreted from the latex canals of a variety of plant species that contain cauotchouc. Latex is composed of 25-35% caoutchouc, 60-75% water, 2% protein, 2% resin, 1.5% sugar & 1% ash. RUBBER is made by the removal of water from latex.(From Concise Encyclopedia Biochemistry and Molecular Biology, 3rd ed). Hevein proteins are responsible for LATEX HYPERSENSITIVITY. Latexes are used as inert vehicles to carry antibodies or antigens in LATEX FIXATION TESTS.
Leukotriene B4
N-Formylmethionine Leucyl-Phenylalanine
Luminol
SRS-A
A group of LEUKOTRIENES; (LTC4; LTD4; and LTE4) that is the major mediator of BRONCHOCONSTRICTION; HYPERSENSITIVITY; and other allergic reactions. Earlier studies described a "slow-reacting substance of ANAPHYLAXIS" released from lung by cobra venom or after anaphylactic shock. The relationship between SRS-A leukotrienes was established by UV which showed the presence of the conjugated triene. (From Merck Index, 11th ed)
Respiratory Burst
A large increase in oxygen uptake by neutrophils and most types of tissue macrophages through activation of an NADPH-cytochrome b-dependent oxidase that reduces oxygen to a superoxide. Individuals with an inherited defect in which the oxidase that reduces oxygen to superoxide is decreased or absent (GRANULOMATOUS DISEASE, CHRONIC) often die as a result of recurrent bacterial infections.
Calcimycin
An ionophorous, polyether antibiotic from Streptomyces chartreusensis. It binds and transports CALCIUM and other divalent cations across membranes and uncouples oxidative phosphorylation while inhibiting ATPase of rat liver mitochondria. The substance is used mostly as a biochemical tool to study the role of divalent cations in various biological systems.
Macrophages, Peritoneal
Platelet Activating Factor
Complement C3b
The larger fragment generated from the cleavage of COMPLEMENT C3 by C3 CONVERTASE. It is a constituent of the ALTERNATIVE PATHWAY C3 CONVERTASE (C3bBb), and COMPLEMENT C5 CONVERTASES in both the classical (C4b2a3b) and the alternative (C3bBb3b) pathway. C3b participates in IMMUNE ADHERENCE REACTION and enhances PHAGOCYTOSIS. It can be inactivated (iC3b) or cleaved by various proteases to yield fragments such as COMPLEMENT C3C; COMPLEMENT C3D; C3e; C3f; and C3g.
Peritonitis
INFLAMMATION of the PERITONEUM lining the ABDOMINAL CAVITY as the result of infectious, autoimmune, or chemical processes. Primary peritonitis is due to infection of the PERITONEAL CAVITY via hematogenous or lymphatic spread and without intra-abdominal source. Secondary peritonitis arises from the ABDOMINAL CAVITY itself through RUPTURE or ABSCESS of intra-abdominal organs.
Complement Pathway, Alternative
Complement activation initiated by the interaction of microbial ANTIGENS with COMPLEMENT C3B. When COMPLEMENT FACTOR B binds to the membrane-bound C3b, COMPLEMENT FACTOR D cleaves it to form alternative C3 CONVERTASE (C3BBB) which, stabilized by COMPLEMENT FACTOR P, is able to cleave multiple COMPLEMENT C3 to form alternative C5 CONVERTASE (C3BBB3B) leading to cleavage of COMPLEMENT C5 and the assembly of COMPLEMENT MEMBRANE ATTACK COMPLEX.
Lectins, C-Type
Mannose-Binding Lectins
Arachidonic Acid
An unsaturated, essential fatty acid. It is found in animal and human fat as well as in the liver, brain, and glandular organs, and is a constituent of animal phosphatides. It is formed by the synthesis from dietary linoleic acid and is a precursor in the biosynthesis of prostaglandins, thromboxanes, and leukotrienes.
Tetradecanoylphorbol Acetate
Complement Activation
Complement C3
A glycoprotein that is central in both the classical and the alternative pathway of COMPLEMENT ACTIVATION. C3 can be cleaved into COMPLEMENT C3A and COMPLEMENT C3B, spontaneously at low level or by C3 CONVERTASE at high level. The smaller fragment C3a is an ANAPHYLATOXIN and mediator of local inflammatory process. The larger fragment C3b binds with C3 convertase to form C5 convertase.
Nitroblue Tetrazolium
Properdin
A 53-kDa protein that is a positive regulator of the alternate pathway of complement activation (COMPLEMENT ACTIVATION PATHWAY, ALTERNATIVE). It stabilizes the ALTERNATIVE PATHWAY C3 CONVERTASE (C3bBb) and protects it from rapid inactivation, thus facilitating the cascade of COMPLEMENT ACTIVATION and the formation of MEMBRANE ATTACK COMPLEX. Individuals with mutation in the PFC gene exhibit properdin deficiency and have a high susceptibility to infections.
Phagosomes
Macrophage-1 Antigen

Complement Factor B
Agammaglobulinemia
Complement Pathway, Classical
Complement activation initiated by the binding of COMPLEMENT C1 to ANTIGEN-ANTIBODY COMPLEXES at the COMPLEMENT C1Q subunit. This leads to the sequential activation of COMPLEMENT C1R and COMPLEMENT C1S subunits. Activated C1s cleaves COMPLEMENT C4 and COMPLEMENT C2 forming the membrane-bound classical C3 CONVERTASE (C4B2A) and the subsequent C5 CONVERTASE (C4B2A3B) leading to cleavage of COMPLEMENT C5 and the assembly of COMPLEMENT MEMBRANE ATTACK COMPLEX.

Sepsis
Systemic inflammatory response syndrome with a proven or suspected infectious etiology. When sepsis is associated with organ dysfunction distant from the site of infection, it is called severe sepsis. When sepsis is accompanied by HYPOTENSION despite adequate fluid infusion, it is called SEPTIC SHOCK.
Compassionate Use Trials
Providing an investigational therapy to a patient who is not eligible to receive that therapy in a clinical trial, but who has a serious or life-threatening illness for which other treatments are not available. Compassionate use trials allow patients to receive promising but not yet fully studied or approved therapies when no other treatment option exists. Also called expanded access trial.
Candidiasis
Activation of stimulus-specific serine esterases (proteases) in the initiation of platelet secretion. I. Demonstration with organophosphorus inhibitors. (1/1146)
The effect of organophosphorus inhibitors of serine esterases (proteases) on secretion from washed rabbit platelets was examined. Five noncytotoxic stimuli were employed: collagen, thrombin, heterologous anti-platelet antibody (in the absence of complement), rabbit C3 bound to zymosan, and platelet activating factor derived from antigen-stimulated, IgE-sensitized rabbit basophils. Diisoprophyl phosphofluoridate, three series of p-nitrophenyl ethyl phosphonates, and a series of cyclohexyl phenylalkylphosphonofluridates were all found to be inhibitory to the platelet secretion. These are irreversible inhibitors of serine proteases but in this system were only inhibitory if added to the platelets concurrently with the stimuli. Pretreatment of either the platelets or the stimuli with the inhibitors followed by washing, was without effect on the subsequent reaction. This suggested the involvement of stimulus-activatable serine proteases in the secretory process. The concept was supported by finding that nonphosphorylating phosphonates or hydrolyzed phosphonates or phosphonofluoridates were without inhibitory action. The effect of a series of phosphonates or phosphonoflouridates in inhibiting each stimulus exhibited a unique activity-structure profile. The demonstration of such unique profiles with four series of inhibitors for each of the five stimuli was interpreted as demonstrating that a specific activatable serine protease was involved in the platelet secretory response to each stimulus. (+info)Acidification of the phagosome in Crassostrea virginica hemocytes following engulfment of zymosan. (2/1146)
Phagocytic hemocytes are responsible for engulfing and internally degrading foreign organisms within the hemolymph and tissue of the eastern oyster, Crassostrea virginica. Since rapid acidification of the phagosome lumen is typically essential for activation of hydrolytic and reactive oxygen intermediate (ROI) producing enzymes in vertebrate cells, we measured phagosomal pH in oyster hemocytes by using the emission fluorescence of two fluorescent probes, rhodamine and Oregon Green 488 (OG 488), conjugated to zymosan to determine whether oyster hemocyte phagosomes become acidified after phagocytosis of zymosan. The average pH of 1079 phagosomes within 277 hemocytes 1 h after phagocytosis of zymosan was 3.9 +/- 0.03. Observations of 141 hemocytes with internalized zymosan by light microscopy revealed that, over a 60-min time period, 51% of highly granular hemocytes became partially granular, and 29% became agranular. In addition, 83% of partially granular hemocytes containing zymosan at time = 0 became agranular within 60 min. A comparison revealed that the phagosomes of agranular hemocytes were much more acidic (pH 3.1 +/- 0.02) than those of highly granular hemocytes (4.9 +/- 0.02; P < 0.05). These values are significantly lower than most reported in the literature for blood cells from metazoan organisms. (+info)Effect of nitric oxide donors on oxygen-dependent cytotoxic responses mediated by neutrophils. (3/1146)
We analyzed the effect of nitric oxide (NO) on oxygen-dependent cytotoxic responses mediated by neutrophils against unopsonized erythrocytes using three NO donors: S-nitrosoglutathione (GSNO), S-nitroso-N-acetylpenicillamine (SNAP), and sodium nitroprusside (SNP). Neutrophils were treated with these compounds for 1-2 min at 37 degrees C and cytotoxicity was then triggered in the presence of NO donors by precipitating immune complexes, aggregated IgG, the chemotactic peptide FMLP, or opsonized zymosan. GSNO induced, in all cases, a marked increase in cytotoxic responses, while SNAP moderately increased cytotoxicity triggered by immune complexes, aggregated IgG, or Z, opsonized zymosen, without modifying those responses induced by FMLP. By contrast, SNP dramatically suppressed cytotoxicity triggered by all of the stimuli assessed. The enhancing effects mediated by GSNO and SNAP did not depend on the stimulation of guanylyl cyclase and were prevented by the NO scavengers hemoglobin and PTIO (2-phenyl-4,4,5,5-tetramethyl-imidazoline-1-oxyl 3-oxide). The inhibitory activity of SNP, on the other hand, was not prevented by NO scavengers, suggesting that it cannot be ascribed to the release of NO. In another set of experiments, neutrophils were pretreated with GSNO or SNAP for different times. Then cells were washed to remove NO donors from the culture medium, and cytotoxicity was triggered by different stimuli. It was found that neutrophils must be pretreated with NO donors for at least 4 h to increase cytotoxic responses, and pretreatment for longer periods (i.e., 8 or 18 h) further increased cytotoxicity. Not only cytotoxic responses, but also the production of O2- and H2O2, and the release of myeloperoxidase were increased under these conditions. (+info)Selective regulation of cytokine induction by adenoviral gene transfer of IkappaBalpha into human macrophages: lipopolysaccharide-induced, but not zymosan-induced, proinflammatory cytokines are inhibited, but IL-10 is nuclear factor-kappaB independent. (4/1146)
Macrophages are the major cytokine producers in chronic inflammatory diseases, but the biochemical pathways regulating cytokine production are poorly understood. This is because genetic tools to dissect signaling pathways cannot be used in macrophages because of difficulties in transfection. We have developed an adenoviral technique to achieve high efficiency gene delivery into macrophages and recently showed that spontaneous TNF-alpha production in rheumatoid arthritis joint cells, chiefly from macrophages, is 75% blocked by adenoviral transfer of IkappaBalpha. In this report we use the same adenovirus to investigate whether the production of a number of proinflammatory cytokines (e.g., TNF-alpha, IL-1beta, IL-6, and IL-8) from human macrophages depends on NF-kappaB. While the cytokine response to certain inducers, such as LPS, PMA, and UV light, is blocked by overexpression of IkappaBalpha, the response to zymosan is not. In contrast, anti-inflammatory mediators (IL-10 and IL-1 receptor antagonist) induced by LPS are only marginally inhibited by IkappaBalpha excess. These studies demonstrate several new points about macrophage cytokine production. First, there is heterogeneity of mechanisms regulating both the proinflammatory and anti-inflammatory cytokines within populations of a single cell type. In addition, the results confirm the utility of the adenoviral technique for functional analysis of cytokine induction. The results also confirm that there are autocrine and paracrine interactions regulating cytokine synthesis within a single cell type. The selectivity of NF-kappaB blockade for proinflammatory but not anti-inflammatory mediators indicates that in macrophages, NF-kappaB may be a good target for the treatment of chronic inflammatory diseases. (+info)Extracellular acidification induces human neutrophil activation. (5/1146)
In the current work, we evaluated the effect of extracellular acidification on neutrophil physiology. Neutrophils suspended in bicarbonate-buffered RPMI 1640 medium adjusted to acidic pH values (pH 6.5-7.0) underwent: 1) a rapid transient increase in intracellular free calcium concentration levels; 2) an increase in the forward light scattering properties; and 3) the up-regulation of surface expression of CD18. By contrast, extracellular acidosis was unable to induce neither the production of H2O2 nor the release of myeloperoxidase. Acidic extracellular pH also modulated the functional profile of neutrophils in response to conventional agonists such as FMLP, precipiting immune complexes, and opsonized zymosan. It was found that not only calcium mobilization, shape change response, and up-regulation of CD18 expression but also production of H2O2 and release of myeloperoxidase were markedly enhanced in neutrophils stimulated in acidic pH medium. Moreover, extracellular acidosis significantly delayed neutrophil apoptosis and concomitantly extended neutrophil functional lifespan. Extracellular acidification induced an immediate and abrupt fall in the intracellular pH, which persisted over the 240-s analyzed. A similar abrupt drop in the intracellular pH was detected in cells suspended in bicarbonate-supplemented PBS but not in those suspended in bicarbonate-free PBS. A role for intracellular acidification in neutrophil activation is suggested by the fact that only neutrophils suspended in bicarbonate-buffered media (i.e., RPMI 1640 and bicarbonate-supplemented PBS) underwent significant shape changes in response to extracellular acidification. Together, our results support the notion that extracellular acidosis may intensify acute inflammatory responses by inducing neutrophil activation as well as by delaying spontaneous apoptosis and extending neutrophil functional lifespan. (+info)Participation of cofilin in opsonized zymosan-triggered activation of neutrophil-like HL-60 cells through rapid dephosphorylation and translocation to plasma membranes. (6/1146)
We studied the roles of cofilin, an actin-binding phosphoprotein, in superoxide production of neutrophil-like HL-60 cells triggered by opsonized zymosan (OZ). OZ caused dephosphorylation of cofilin as well as a transient increase of F-actin. Both reactions were complete within 30 s. Okadaic acid (OA) magnified the OZ-triggered O2--production 3.3-fold at 1 microM, but inhibited it completely at 5 microM. We used these critical concentrations to study the effects of OA on changes in phosphorylation and intracellular localization of cofilin. The OZ-induced dephosphorylation of cofilin was inhibited by 5 microM OA but not by 1 microM OA. Subcellular fractionation and immunoblotting revealed that 1 microM OA increased cofilin on the phagosomal membranous fraction but 5 microM OA decreased it. At 1 microM, OA increased translocation of p47phox to membranes, which may explain in part the enhancing effect of 1 microM OA. Confocal laser scanning microscopy showed that: (i) Cofilin diffused throughout the cytosol of resting cells, but accumulated at the plasma membranes forming phagocytic vesicles in activated cells. (ii) At 1 microM, OA had little effect on the OZ-evoked translocation of cofilin, whereas 5 microM OA suppressed it completely. (iii) OA alone, which could not trigger the phagocytic respiratory burst, did not cause any change in the distribution of cofilin at such concentrations. Furthermore, in a superoxide-producing cell-free system employing membranous and cytosolic fractions, affinity-purified anti-cofilin antibody showed an enhancing effect. These results suggest that cofilin participates in the superoxide production of the OZ-activated phagocytes through dephosphorylation and translocation. The roles of cofilin in the activated leukocytes will be discussed. (+info)Roles of a macrophage receptor with collagenous structure (MARCO) in host defense and heterogeneity of splenic marginal zone macrophages. (7/1146)
Class A type I and type II macrophage scavenger receptors (MSR-A) and a macrophage receptor with collagenous structure (MARCO) are trimeric membrane glycoproteins mediating the uptake of chemically modified low density lipoproteins. MSR-A is expressed constitutively in several tissue macrophages and in liver sinusoidal endothelial cells, whereas MARCO is expressed constitutively in splenic marginal zone macrophages and in macrophages and endothelial cells in the lymphatic medullary sinuses of lymph nodes. The administration of LPS, zymosan, BCG, or L. monocytogenes to mice resulted in marked and transient MARCO expression and in the upregulation of MSR-A expression in the liver and spleen. In osteopetrotic (op) mutant mice defective in the production on M-CSF, ER-TR9-positive marginal zone macrophages and MOMA-1-positive marginal metallophilic macrophages were absent, whereas MARCO-expressing marginal zone macrophages were present, indicating the heterogeneity of marginal zone macrophages. Intravenous administration of BCG resulted in marked accumulation of BCG bacilli in the both marginal zone macrophages and marginal metallophilic macrophages in littermate control mice. In contrast, BCG bacilli were incorporated almost exclusively by MARCO-expressing marginal zone macrophages in op/op mice. These results indicate that MARCO is not only expressed constitutively in specific macrophage subpopulations but is also induced by various bacterial antigens and plays a role in host defense against bacteria. (+info)Phospholipase D-derived phosphatidic acid is involved in the activation of the CD11b/CD18 integrin in human eosinophils. (8/1146)
Priming of human eosinophils is an essential event for the respiratory burst induced by serum-opsonized particles [serum-treated zymosan (STZ)]. In this study we have found that treatment of eosinophils with platelet-activating factor (PAF) leads to activation of phospholipase D. Inhibition of the formation of phospholipase D-derived products by ethanol resulted in about 90% inhibition of PAF-induced binding of fluorescent STZ particles to the cells, but only when ethanol was added to the cells before treatment with PAF. When ethanol was added after treatment with PAF, only a minor inhibition of the STZ binding and STZ-induced response was observed. These results indicate that phospholipase D-derived phosphatidic acid is involved in PAF priming, without having an effect on STZ stimulation. In the presence of propranolol, which inhibits phosphatidic acid-phosphatase activity, binding of STZ particles to human eosinophils induced by suboptimal concentrations of PAF was enhanced, indicating that phosphatidic acid and not diradylglyceride is the relevant molecule derived from phospholipase D activity. Addition of cell-permeant diC8-phosphatidic acid (DiC8-PA) to human eosinophils resulted in CD11b/CD18-dependent adhesion, both to STZ particles and fibronectin-coated wells, without significant upregulation of CD11b/CD18. The DiC8-PA-induced adhesion was not mediated via the fatty acid moiety, because other C8-lipids such as 1,2-diC8-phosphatidylcholine, 1-C8-monoacylglycerol or C8-ceramide were without effect. Activation of protein kinase C with PMA or 1,2-diC8-diacylglycerol did result in enhanced STZ binding. However, under these latter conditions upregulation of CD11b/CD18 was observed. Taken together, these results suggest that phospholipase D-derived PA is involved in changing the affinity of the CD11b/CD18 integrin for its ligands. (+info)

Beta-glucan
Cereal and fungal products have been used for centuries for medicinal and cosmetic purposes; however, the specific role of β-glucan was not explored until the 20th century. β-glucans were first discovered in lichens, and shortly thereafter in barley. A particular interest in oat β-glucan arose after a cholesterol lowering effect from oat bran reported in 1981.[2] In 1997, the FDA approved of a claim that intake of at least 3.0 g of β-glucan from oats per day decreased absorption of dietary cholesterol and reduced the risk of coronary heart disease. The approved health claim was later amended to include these sources of β-glucan: rolled oats (oatmeal), oat bran, whole oat flour, oatrim (the soluble fraction of alpha-amylase hydrolyzed oat bran or whole oat flour), whole grain barley and barley beta-fiber. An example of an allowed label claim: Soluble fiber from foods such as oatmeal, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease. A serving of ...
Oligosaccharide
1 All cells are coated in either glycoproteins or glycolipids, both of which help determine cell types.[7] Lectins, or proteins that bind carbohydrates, can recognize specific oligosaccharides and provide useful information for cell recognition based on oligosaccharide binding.[citation needed] An important example of oligosaccharide cell recognition is the role of glycolipids in determining blood types. The various blood types are distinguished by the glycan modification present on the surface of blood cells.[15] These can be visualized using mass spectrometry. The oligosaccharides found on the A, B, and H antigen occur on the non-reducing ends of the oligosaccharide. The H antigen (which indicates an O blood type) serves as a precursor for the A and B antigen.[7] Therefore, a person with A blood type will have the A antigen and H antigen present on the glycolipids of the red blood cell plasma membrane. A person with B blood type will have the B and H antigen present. A person with AB blood ...
Disaccharide
A disaccharide (also called a double sugar or bivose[1]) is the sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose,[2] and maltose. Disaccharides are one of the four chemical groupings of carbohydrates (monosaccharides, disaccharides, oligosaccharides, and polysaccharides). The most common types of disaccharides-sucrose, lactose, and maltose-have 12 carbon atoms, with the general formula C12H22O11. The differences in these disaccharides are due to atomic arrangements within the molecule.[3] The joining of simple sugars into a double sugar happens by a condensation reaction, which involves the elimination of a water molecule from the functional groups only. Breaking apart a double sugar into its two simple sugars is accomplished by hydrolysis with the help of a type of enzyme called a disaccharidase. As building the larger sugar ejects a water molecule, ...

Sucrose
The production of table sugar has a long history. Some scholars claim Indians discovered how to crystallize sugar during the Gupta dynasty, around AD 350.[19] Other scholars point to the ancient manuscripts of China, dated to the 8th century BC, where one of the earliest historical mentions of sugar cane is included along with the fact that their knowledge of sugar cane was derived from India.[20] Further, it appears that by about 500 BC, residents of present-day India began making sugar syrup and cooling it in large flat bowls to make raw table sugar crystals that were easier to store and transport. In the local Indian language, these crystals were called khanda (खण्ड), which is the source of the word candy.[21] The army of Alexander the Great was halted on the banks of river Indus by the refusal of his troops to go further east. They saw people in the Indian subcontinent growing sugarcane and making granulated, salt-like sweet powder, locally called sākhar (साखर), pronounced ...
Dietary fiber
Many molecules that are considered to be "dietary fiber" are so because humans lack the necessary enzymes to split the glycosidic bond and they reach the large intestine. Many foods contain varying types of dietary fibers, all of which contribute to health in different ways. Dietary fibers make three primary contributions: bulking, viscosity and fermentation.[49] Different fibers have different effects, suggesting that a variety of dietary fibers contribute to overall health. Some fibers contribute through one primary mechanism. For instance, cellulose and wheat bran provide excellent bulking effects, but are minimally fermented. Alternatively, many dietary fibers can contribute to health through more than one of these mechanisms. For instance, psyllium provides bulking as well as viscosity. Bulking fibers can be soluble (i.e., psyllium) or insoluble (i.e., cellulose and hemicellulose). They absorb water and can significantly increase stool weight and regularity. Most bulking fibers are not ...
Glycosaminoglycan
HSGAG and CSGAG modified proteoglycans first begin with a consensus Ser-Gly/Ala-X-Gly motif in the core protein. Construction of a tetrasaccharide linker that consists of -GlcAβ1-3Galβ1-3Galβ1-4Xylβ1-O-(Ser)-, where xylosyltransferase, β4-galactosyl transferase (GalTI),β3-galactosyl transferase (GalT-II), and β3-GlcA transferase (GlcAT-I) transfer the four monosaccharides, begins synthesis of the GAG modified protein. The first modification of the tetrasaccharide linker determines whether the HSGAGs or CSGAGs will be added. Addition of a GlcNAc promotes the addition of HSGAGs while addition of GalNAc to the tetrasaccharide linker promotes CSGAG development.[5] GlcNAcT-I transfers GlcNAc to the tetrasaccahride linker, which is distinct from glycosyltransferase GlcNAcT-II, the enzyme that is utilized to build HSGAGs. EXTL2 and EXTL3, two genes in the EXT tumor suppressor family, have been shown to have GlcNAcT-I activity. Conversely, GalNAc is transferred to the linker by the enzyme GalNAcT ...
Amylopectin
... /ˌæmɪloʊˈpɛktɪn/ is a water-soluble[1][2] polysaccharide and highly branched polymer of α-glucose units found in plants. It is one of the two components of starch, the other being amylose. Amylopectin bears a straight/linear chain along with a number of side chains which may be branched further. Glucose units are linked in a linear way with α(1→4) Glycosidic bonds. Branching usually occurs at intervals of 25 residues. At the places of origin of a side chain, the branching that takes place bears an α(1→6) Glycosidic bond , resulting in a soluble molecule that can be quickly degraded as it has many end points onto which enzymes can attach. Wolform and Thompson (1956) have also reported α(1→3)linkages in case of Amylopectin. Amylopectin contains a larger number of Glucose units (2000 to 200,000) as compared to Amylose containing 200 to 1000 α-Glucose units. In contrast, amylose contains very few α(1→6) bonds, or even none at all. This causes amylose to be hydrolyzed ...
