As such, it is a receptor for FIBRINOGEN; VON WILLEBRAND FACTOR; FIBRONECTIN; VITRONECTIN; and THROMBOSPONDINS. A deficiency of GPIIb-IIIa results in GLANZMANN THROMBASTHENIA.Platelet Glycoprotein GPIb-IX Complex: Platelet membrane glycoprotein complex essential for normal platelet adhesion and clot formation at sites of vascular injury. It is composed of three polypeptides, GPIb alpha, GPIb beta, and GPIX. Glycoprotein Ib functions as a receptor for von Willebrand factor and for thrombin.

The gene for May-Hegglin anomaly localizes to a <1-Mb region on chromosome 22q12.3-13.1. (1/259)

The May-Hegglin anomaly (MHA) is an autosomal dominant platelet disorder of unknown etiology. It is characterized by thrombocytopenia, giant platelets, and leukocyte inclusion bodies, and affected heterozygotes are predisposed to bleeding episodes. The MHA gene has recently been localized, by means of linkage analysis, to a 13.6-cM region on chromosome 22, and the complete chromosome 22 sequence has been reported. We recently performed a genome scan for the MHA gene in 29 members of a large, multigenerational Italian family, and we now confirm that the MHA locus is on chromosome 22q12. 3-13.1. The maximal two-point LOD score of 4.50 was achieved with the use of marker D22S283, at a recombination fraction of.05. Haplotype analysis narrowed the MHA critical region to 6.6 cM between markers D22S683 and D22S1177. It is of note that the chromosome 22 sequence allowed all markers to be ordered correctly, identified all the candidate genes and predicted genes, and specifically determined the physical size of the MHA region to be 0. 7 Mb. These results significantly narrow the region in which the MHA gene is located, and they represent the first use of chromosome 22 data to positionally clone a disease gene.  (+info)

Ultrastructural aspects of interactions of platelets with microcrystalline collagen. (2/259)

Whole blood anticoagulated with EDTA was stirred with high concentrations of a microcrystalline bovine dermal collagen preparation in order to study the interactions of blood cells with collagen at the ultrastructural level. Blood from normal subjects and from patients congenitally deficient in Factors VIII or XII or with thrombasthenia or von Willebrands disease was used. In scanning and transmission electron microscopic studies with blood from normal subjects and patients, platelets were seen to adhere to collagen, develop cell surface undulations, form pseudopods, and undergo morphologic changes suggestive of the release reaction. Although thrombasthenic platelets adhered to collagen, pseudopods formed by these cells were remarkably angulated and nodular. Relatively few von Willebrands platelets adhered to collagen, but those platelets that did adhere underwent the usual sequence of morphologic changes.  (+info)

Low-density lipoprotein activates the small GTPases Rap1 and Ral in human platelets. (3/259)

Physiological concentrations of low-density lipoprotein (LDL) sensitize blood platelets to alpha-thrombin- and collagen-induced secretion, and after prolonged contact trigger secretion independent of other agonists. Here we report that LDL activates the small GTPases Rap1 and Ral but not Ras, as assessed by specific precipitation of the GTP-bound enzymes. In unstirred suspensions, the inhibitor SB203580 blocks Rap1 activation by 60-70%, suggesting activation via p38 mitogen-activated protein kinase and a second, unidentified route. Inhibitors of cyclooxygenase (indomethacin) and the thromboxane A(2) (TxA(2)) receptor (SQ30741) induce complete inhibition, indicating that Rap1 activation is the result of TxA(2) formation. Stirring reveals a second, TxA(2)-independent Rap1 activation, which correlates quantitatively with a slow induction of dense granule secretion. Both pathways are unaffected by inhibitors of ligand binding to integrin alpha(IIb)beta(3). The results suggest that Rap1 and Ral, but not Ras, may take part in signalling routes initiated by LDL that initially enhance the sensitivity of platelets to other agonists and later trigger LDL-dependent secretion.  (+info)

Improved platelet counting using two-dimensional laser light scatter. (4/259)

Clinical management of platelet disorders depends on accurate platelet counts. We evaluated a new analytic approach for platelet counting based on improved platelet discrimination. Current automated counting methods provide accurate platelet counts for most samples but often are unable to discriminate platelets accurately from nonplatelet particles such as microcytic RBCs, RBC fragments, and cellular debris that may falsely elevate platelet counts. The new approach measures 2 light-scatter angles of platelets and nonplatelet particles as they pass through a laser beam. The volume and refractive index of each platelet and particle are derived from the light-scatter measurements using the Mie scattering theory. Together, these 2 measurements provide improved platelet discrimination compared with 1-dimensional methods. With its improved discrimination, 2-dimensional platelet analysis provides more accurate platelet counts in samples containing interfering particles and may contribute to more effective clinical management of patients with platelet disorders.  (+info)

Mediterranean macrothrombocytopenia. (5/259)

Platelet count, platelet size, and circulating platelet biomass concentration estimates made with an erythrocyte-calibrated electronic sizing system on EDTA-anticoagulated blood samples gave population medians and 95% ranges for 145 asymptomatic Mediterranean and 200 healthy Northern European subjects. The Mediterraneans had lower platelet counts [161,000 (89,000-290,000)/mul compared with 219,000 (148,000-323,000)/mul] and higher arithmetic mean volumes [17.8 (10.8-29.2) cu mum compared with 12.4 (9.9-15.6) cu mum], while the individual lognormal platelet size distribution profiles were comparable [geomatric standard deviations of 1.78 (1.60-1.98) against 1.70 (1.54-1.88)]; and the platelet biomass concentrations, given by count per microliter times mean volume times 10- minus 7 and expressed as a volumetric percentage of whole blood, were almost identical [0.286% (0.216%-0.379%) against 0.272% (0.201%-0.367%)]. Mediterranean macrothrombocytopenia is, therefore, considered a benign morphologic variant that requires differentiation from thrombocytopenias in which the circulating platelet biomass concentration is decreased.  (+info)

A pregnancy complicated with Fechtner syndrome: a case report. (6/259)

A 21-year-old woman was diagnosed with Fechtner syndrome at 15 weeks gestation. She had a familial history of this disorder; her mother, two siblings and maternal grandmother were also affected. She presented with neither bleeding from the genital tract nor symptoms suggestive of placental abruption. Labor progressed uneventfully and resulted in the birth of a healthy female infant weighing 3436 g at 41 weeks of gestation. The puerperium was uneventful for both mother and infant.  (+info)

Autosomal-dominant giant platelet syndromes: a hint of the same genetic defect as in Fechtner syndrome owing to a similar genetic linkage to chromosome 22q11-13. (7/259)

Families with 3 different syndromes characterized by autosomal dominant inheritance of low platelet count and giant platelets were studied. Fechtner syndrome is an autosomal-dominant variant of Alport syndrome manifested by nephritis, sensorineural hearing loss, and cataract formation in addition to macrothrombocytopenia and polymorphonuclear inclusion bodies. Sebastian platelet syndrome is an autosomal-dominant macrothrombocytopenia combined with neutrophil inclusions that differ from those found in May-Hegglin syndrome or Chediak-Higashi syndrome or the Dohle bodies described in patients with sepsis. These inclusions are, however, similar to those described in Fechtner syndrome. Other features of Alport syndrome, though, including deafness, cataracts, and nephritis, are absent in Sebastian platelet syndrome. Epstein syndrome is characterized by macrothrombocytopenia without neutrophil inclusions, in addition to the classical Alport manifestations-deafness, cataracts, and nephritis-and it is also inherited in an autosomal-dominant mode. We mapped the disease-causing gene to the long arm of chromosome 22 in an Italian family with Fechtner syndrome, 2 German families with the Sebastian platelet syndrome, and an American family with the Epstein syndrome. Four markers on chromosome 22q yielded an LOD score greater than 2.76. A maximal 2-point LOD score of 3.41 was obtained with the marker D22S683 at a recombination fraction of 0.00. Recombination analysis placed the disease-causing gene in a 3.37-Mb interval between the markers D22S284 and D22S693. The disease-causing gene interval in these 3 syndromes is similar to the interval described recently in an Israeli family with a slightly different Fechtner syndrome than the one described here. Recombination analysis of these 3 syndromes refines the interval containing the disease-causing gene from 5.5 Mb to 3.37 Mb. The clinical likeness and the similar interval containing the disease-causing gene suggest that the 3 different syndromes may arise from a similar genetic defect.  (+info)

Platelets from a patient heterozygous for the defect of P2CYC receptors for ADP have a secretion defect despite normal thromboxane A2 production and normal granule stores: further evidence that some cases of platelet 'primary secretion defect' are heterozygous for a defect of P2CYC receptors. (8/259)

Two unrelated patients with a congenital bleeding diathesis associated with a severe defect of the platelet ADP receptor coupled to adenylate cyclase (P2(CYC)) have been described so far. In one of them, platelet secretion was shown to be abnormal. We recently showed that platelets with the primary secretion defect (PSD; characterized by abnormal secretion but normal granule stores, thromboxane A(2) production, and ADP-induced primary wave of aggregation) have a moderate defect of P2(CYC). Therefore, the interaction of ADP with the full complement of its receptors seems to be essential for normal platelet secretion, and PSD patients may be heterozygotes for the congenital severe defect of P2(CYC). In this study, we describe 2 new related patients with a severe defect of P2(CYC) and the son of one of them, who is to be considered an obligate heterozygote for the defect. The 2 patients with the severe defect had lifelong histories of abnormal bleeding, prolonged bleeding times, abnormalities of platelet aggregation and secretion, lack of inhibition of adenylate cyclase by ADP, and a deficiency of platelet-binding sites for [(33)P]2 MeS-ADP (240 and 225 sites per platelet; normal range, 530 to 1102). The son of one of them had a mildly prolonged bleeding time and abnormalities of platelet aggregation and secretion similar to those found in patients with PSD. In addition, his platelets showed a moderate defect of binding sites for [(33)P]2 MeS-ADP (430 sites per platelet) and of adenylate cyclase inhibition by ADP. This study of a family with the platelet disorder characterized by a defect of the platelet P2(CYC) receptor supports our hypothesis that the full complement of the platelet ADP receptors is essential for normal platelet secretion and that some patients with the common, ill-defined diagnosis of PSD are actually heterozygous for the defect.  (+info)

Giant platelet disorders are rare disorders featuring abnormally large platelets, thrombocytopenia and a tendency to bleeding. Giant platelets cannot stick adequately to an injured blood vessel walls, resulting in abnormal bleeding when injured. Giant platelet disorder occurs for inherited diseases like Bernard-Soulier syndrome, gray platelet syndrome and May-Hegglin anomaly. Symptoms usually present from the period of birth to early childhood as: nose bleeds, bruising, and/or gum bleeding. Problems later in life may arise from anything that can cause internal bleeding such as: stomach ulcers, surgery, trauma, or menstruation. Abnormality of the abdomen, nosebleeds, heavy menstrual bleeding, purpura, too few platelets circulating in the blood, and prolonged bleeding time have also been listed as symptoms of various Giant Platelet Disorders. Many of the further classifications of Giant Platelet Disorder occur as a result of being genetically passed down through families as an autosomal recessive ...
Quebec Platelet Disorder (QPD) is a rare, autosomal dominant bleeding disorder described in a family from the province of Quebec in Canada. Individuals with QPD are at risk for experiencing a number of bleeding symptoms, including joint bleeds, hematuria, and large bruising. In 2010, the genetic cause of QPD has been determined as a mutation involving an extra copy of the uPA (urokinase plasminogen activator) gene http://bloodjournal.hematologylibrary.org/content/115/6/1264.long.[permanent dead link] The mutation causes overproduction of an enzyme that accelerates blood clot breakdown. The disorder is characterized by large amounts of the fibrinolytic enzyme urokinase-type plasminogen activator (u-PA) in platelets. Consequently, stored platelet plasminogen is converted to plasmin, which is thought to play a role in degrading a number of proteins stored in platelet α-granules. These proteins include platelet factor V, Von Willebrand factor, fibrinogen, thrombospondin-1, and osteonectin. There is ...
Platelets are small cells that circulate in the blood. They are involved in the formation of blood clots and the repair of damaged blood vessels.. When a blood vessel is injured, platelets stick to the damaged area and spread along the surface to stop the bleeding. This process is called adhesion. At the same time, chemical signals are released from small sacks inside the platelets called granules. This process is called secretion. These chemicals attract other platelets to the site of injury and make them clump together to form what is called a platelet plug. This process is called aggregation. Sometimes the platelet plug is enough to stop a bleed. If the wound is large, however, other proteins called clotting factors are recruited to the site of injury. These clotting factors work together on the surface of the platelets to form and strengthen the blood clot.. ...

A person with von Willebrand Disease (VWD) or a platelet disorder will have trouble making a platelet plug. Some people with von Willebrand Disease (VWD) also have trouble making a fibrin clot because they dont have enough factor VIII. Without a platelet plug, blood will continue to leak from an injured blood vessel. In time, the body can make a fibrin clot to stop the bleeding but it will not be as strong as a clot that had a good platelet plug.. If a persons platelets have trouble sticking to the wall of an injured blood vessel, he or she has an adhesion disorder. If the platelets dont stick well to each other, it is an aggregation disorder. If the platelets dont release the chemicals that signal other platelets to join in making the plug, it is a secretion disorder. The platelet disorders described in The Handbook are listed below.. ...
Congenital disorders of platelet function are a heterogeneous group of disorders that are often not detected until bleeding occurs. In clinical settings only a few methods have proven to be useful for identification and classification of inherited platelet disorders. For a rational diagnostic approach, a stepwise algorithm is recommended. Patient history and clinical investigation are mandatory. Von Willebrand disease and other coagulation disorders should always be ruled out prior to specific platelet testing. Platelet count, size, volume (MPV) and morphology may guide further investigations. The PFA-100® CT is suited for screening for severe platelet defects. Platelet aggregometry allows assessment of multiple aspects of platelet function. Flow cytometry enables diagnosis of thrombasthenia Glanzmann, Bernard-Soulier syndrome and storage pool defects. Molecular genetics may confirm a putative diagnosis or pave the way for identifying new defects. We present an unabridged version of the ...
SUMMARY Acquired qualitative platelet disorders are frequent causes of abnormal platelet function measured in vitro, although by themselves are usually associated with little or no clinical bleeding. However, there are important exceptions. Nevertheless, their major clinical impact becomes apparent in the additional presence of thrombocytopenia, or additional acquired or congenital disorders of hemostasis. Acquired disorders of platelet function can be conveniently classified into those that result from drugs, hematologic diseases, and systemic disorders. Drugs are the most frequent cause of acquired qualitative platelet dysfunction. Aspirin is the most notable drug in this regard because of its frequent use, its irreversible effect on platelet prostaglandin synthesis, and its documented effect on hemostatic competency, although this effect is minimal in normal individuals. Other nonsteroidal antiinflammatory drugs reversibly inhibit platelet prostaglandin synthesis and usually have little ...

May-Hegglin anomaly is an inherited dominant condition in which large (2 - 5 um) basophilic inclusions, resembling Döhle bodies, are present in granulocytes, including neutrophils, eosinophils, basophils, and monocytes. The inclusions are caused by accumulation of free ribosomes. A May-Hegglin body is indicated by the black arrow in the image on the right. Note that this inclusion is well-defined and there is no evidence of toxic granulation in the cytoplasm. When Döhle-like bodies are identified, May-Hegglin anomaly should be considered in the differential diagnosis, even though this entity is rare. Giant platelets containing few fine granules are also characteristic of May-Hegglin anomaly. The red arrow in the image on the right points to a giant platelet, observed in the same field as a neutrophil containing a May-Hegglin body. Sometimes the platelets have bizarre shapes and variable sizes. Variable degrees of thrombocytopenia complicated by mild bleeding problems and purpura may accompany ...
Chromosome changes in the bone marrow (BM) of patients with persistent cytopenia are often considered diagnostic for a myelodysplastic syndrome (MDS). Comprehensive cytogenetic evaluations may give evidence of the real pathogenetic role of these changes in cases with cytopenia without morphological signs of MDS. Chromosome anomalies were found in the BM of three patients, without any morphological evidence of MDS: 1) an acquired complex rearrangement of chromosome 21 in a boy with severe aplastic anaemia (SAA); the rearrangement caused the loss of exons 2-8 of the RUNX1 gene with subsequent hypoexpression. 2) a constitutional complex rearrangement of chromosome 21 in a girl with congenital thrombocytopenia; the rearrangement led to RUNX1 disruption and hypoexpression. 3) an acquired paracentric inversion of chromosome 1, in which two regions at the breakpoints were shown to be lost, in a boy with aplastic anaemia; the MPL gene, localized in chromosome 1 short arms was not mutated neither disrupted, but

It is one of the most common rare genetic diseases that usually involves the bone marrow where an impaired labor (inability to produce blood cells) is evident. Moreover, this form of anemia is often associated with birth defects, tendency of bleeding, frequent appearance of liver tumors, short stature, myelodysplastic syndrome (the blood stem cells - immature cells - do not become mature blood cells) in about 60-75% of patients. Also, in this form of anemia, there are possible notable anomalies like ectopic kidney, pelvic kidney, hydronephrosis and hydroureter, open ductus arteriosus, aortic stenosis, coarctation of aorta, missing lobes of the lungs, atrial septal defect, tetralogy of Fallot, pseudotruncus, and other problems in the development such as Bells palsy, arterial malformations of brain tissue..

We have described a comprehensive and cost-effective strategy for the diagnosis of BPDs. The HTS platform, and accompanying processing and filtering methods, have high sensitivity (100% based on 159 samples) to detect and shortlist causal variants (SNVs, indels, and CNVs) when the variants are known to be in a BPD gene on the ThromboGenomics platform. When the phenotype is strongly indicative of the presence of a particular disease etiology but the variants are unknown, sensitivity remains high (,90% based on 61 samples). Our variant filtering approach has high specificity (,99.5%) because it greatly reduces the number of candidates requiring consideration by the MDT and, as we have shown, HPO-based prioritization methods may reduce the burden on MDTs even further by highlighting pathogenic or likely pathogenic variants as the top candidate in ∼85% of cases. Sanger results have been overturned by results obtained by HTS, and the CNV-calling pipeline compares favorably with other assays such as ...

Storage pool disease involving the dense granules was first described in 1972. On Wright-stained smears, the platelets are morphologically normal but are shown to lack d-granules on EM (electron microscopy). Since these granules are the storage sites for serotonin, ADP and ATP, their lack also means a lack of the said substances. ADP and ATP are enhancers of platelet aggregation by activation of more platelets which in turn release their dense granule substances and recruit more platelets. Low levels of platelet ADP, ATP result in bleeding diathesis. Examples of bleeding are: easy bruising, epistaxis, post-surgical bleeding, heavy menstrual bleed.. Use of Impact-R in the Diagnosis of d-SPD. Recent studies of platelet adhesion under high-shear stress have been done on patients with d-SPD. One of these is the Impact-R machine.

One more thing and for sure and I cant not post this. So many of you, my dear friends and followers have kept me in prayer due to my platelet disorder, ITP. When it was first discovered, my platelets were at 700. I was told that if I hadnt gone to the emergency room that day, that I would have died by the following day. It has been a roller coaster ride for nearly a year and a half and I was expected to live no longer than a couple to three weeks when they let me go home after a 44 day hospital stay. Well yesterday, I had my blood work done, and for the first time since I became sick, my platelets are actually within the normal range. Normal is 130,000 to 400,000 and yesterday we found out that I am at 188,000! So all my thanks to each and every one of you. Im doing real well and so much of it has to do with your thoughts and prayers ...

Platelet storage pool deficiencies are rare platelet abnormalities that cause a mild to moderate bleeding disorder. Platelet storage pool deficiencies consist of a number of disorders characterized by a reduction in the number and content of certain types of platelets, called dense granules and alpha granules. The dense granules in platelets serve as a "storage pool" for adenosine triphosphate (ATP), adenosine diphosphate (ADP), serotonin, calcium, and pyrophosphate, which are secreted when platelets are activated. It is thought that the reduced release of ADP may result in the prolonged bleeding times ...
OBJECTIVE: To platelet aggregometry and describe the clinical spectrum of Glanzmanns thrombasthenia diagnosed by platelet aggregometry. STUDY DESIGN: A case-series. PLACE AND DURATION OF STUDY: This study was carried out at the clinical laboratories at the Aga Khan University Hospital, Karachi from January 2003 to January 2006. PATIENTS AND METHODS: All patients irrespective of age and gender presenting with bleeding symptoms and having normal platelet count were evaluated. Demographic details, relevant clinical history along with results of complete blood count, bleeding time and platelet aggregation studies were retrieved through computerized data base and evaluated for the diagnosis of Glanzmanns thrombasthenia. RESULTS: During the study period, 50 out of 2317 patients (2.2%) were diagnosed as Glanzmanns thrombasthenia by platelet aggregometry with male to female ratio of 0.85:1 and median age of 10.2 years (ranging from 3 months to 27 years). Common symptoms were epistaxis, oral and gingival
Bernard-Soulier syndrome, also known as hemorrhagiparous thrombocytic dystrophy, is a rare disorder that prevents a person from being able to stop bleeding after an injury or surgery. A portion of our blood is made up of platelets, which are cells that help blood to clot and therefor stops bleeding. While people affected by Benard-Soulier syndrome have large platelets, they do not have enough. This means that something as small as a paper cut will not clot and stop bleeding for hours. Other symptoms of people affected with Bernard-Soulier syndrome are bleeding gums (the area around your teeth), easy bruising, and heavy menstrual periods. Type A Bernard-Soulier syndrome is different from others because of the specific gene that is affected. Talk with your doctor to find the best treatment if you or a loved one has been diagnosed with Bernard-Soulier syndrome ...
F3 Positional Cloning of the Pallid Gene Reveals a Novel, Syntaxin 13-Interacting Protein Involved in Platelet Storage Pool Deficiency. Liping Huang1, Yien-Ming Kuo2, and Jane Gitschier,1,2. Howard Hughes Medical Institute1 and Departments of Medicine1 and Pediatrics2 University of California, San Francisco, CA 94143-0794. Pallid (pa) is one of 13 platelet storage pool deficiency (SPD) mouse mutants. Pallid animals suffer from prolonged bleeding time, pigment dilution, kidney lysosomal enzyme elevation, serum a1-antitrypsin activity deficiency, and abnormal otolith formation. As in the other mouse mutants of this class, the constellation of findings in pallid suggests a defect in organelle biosynthesis. In this report, we describe the physical mapping, positional cloning, and mutational and functional analysis of the gene defective in pallid. This gene encodes a ubiquitously expressed, highly charged 172-amino-acid protein (pallidin) with no homology to known proteins. A nonsense mutation was ...

Glanzmann thrombasthenia is a genetic platelet disorder in which the platelet have qualitative or quantitative deficiencies of the fibrinogen receptor αIIbβ3. The genes of both of these proteins are on chromosome 17, and 50% activity of each protein is enough to support normal platelet aggregation.
Bassett Hound Thrombopathia is an inherited platelet defect that has plagued the breed since its first description by Johnstone and Lotz in 1979. At the present time, diagnosis of the defect requires the animal(s) be brought to one of the few existing specialized veterinary platelet function laboratories in the country. Although platelet studies do identify affected dogs with clarity, unambiguous identification of carriers is difficult. Identification of the genetic cause would greatly facilitate elimination of this defect from the breed by allowing clear identification of carrier and affected animals without the necessity of having the dog be on the premises of the facility. Many candidate genes need to be sequenced and evaluated to begin to make progress toward identification of the cause. This study not only would potentially identify the genetic cause of Basset Hound Thrombopathia but would also add valuable information to the data base on the canine genome.

If our insurance approves the genetic testing we will go back Tuesday, to Scott and White and then wait 4-6 weeks to see exactly which syndrome Ally has. Dr. Grayson is extremely certain the diagnosis of macrothrombocytes is correct (meaning Ally has giant platelets) and under that umbrella there are 5 possible syndroms that Ally could have. Dr. Grayson thinks hes narrowed it down to May-Hegglin and hopefully this genetic test will confirm this diagnosis. Since its an inherited gene mutation we will probably get Ryan and this baby boy tested at some point. Allys platelet count will always be low...somewhere in the 50-100 thousand instead of the normal 150-450 thousand. But the 5 we got at the hospital was incorrect and once the pathologist looked at her blood under the microscope he diagnoised her with Macrothrombocytes. Hopefully this would only be an issue if she were to need surgery later in life. Shed probably need a platelet transfusion but other than that the May-Hegglin shouldnt ...

Congenital bleeding disorders characterized by abnormal platelet granules include Gray Platelet syndrome (GPS; defective alpha-granules), Hermansky-Pudlak syndrome (HPS; defective delta-granules), and combined alpha delta-storage pool deficiency (alpha delta-SPD). Other diseases associated with variable defects in platelet gamma-granules include Chediak-Higashi, Griscelli, Wiskott-Aldrich, and Thrombocytopenia Absent Radius syndromes. These disorders are models for the study of organelle formation in megakaryocytes and platelets. Characteristics of megakaryocytopoiesis in these disorders have not been investigated because megakaryocytes could not be cultured from patients in sufficient quantities for experimental purposes. Recent advances have made it possible to culture megakaryocytes using serum-free media supplemented with recombinant human thrombopoietin (TPO). Such cultured human megakaryocytes, amplified from bone marrow-derived CD34+ stem cells, synthesize and store organellar proteins ...

Idiopathic pulmonary arterial hypertension (IPAH) is a rare and progressive disease. Several processes are believed to lead to the fatal progressive pulmonary arterial narrowing seen in IPAH including vasoconstriction, cellular proliferation inflammation, vascular remodeling, abnormalities in the lung matrix, and in situ thrombosis. Nitric oxide (NO) produced by NO synthases (NOS) is a potent vasodilator and plays important roles in many other processes including platelet function. Reduced NO levels in patients with IPAH are known to contribute to the development of pulmonary hypertension and its complications. Platelet defects have been implied in IPAH, but original research supporting this hypothesis has been limited. Normal platelets are known to have NOS activity, but little is known about NOS expression and NO production by platelets in patients with IPAH. Here we characterized the phenotype of the platelets in IPAH and show a defect in their ability to be activated in vitro by thrombin ...

Mutations in the human NBEAL2 gene cause gray platelet syndrome (GPS), a bleeding diathesis characterized by a lack of α granules in platelets. The functions of the NBEAL2 protein have not been explored outside platelet biology, but there are reports of increased frequency of infection and abnormal neutrophil morphology in patients with GPS. We therefore investigated the role of NBEAL2 in immunity by analyzing the phenotype of Nbeal2-deficient mice. We found profound abnormalities in the Nbeal2-deficient immune system, particularly in the function of neutrophils and NK cells. Phenotyping of Nbeal2-deficient neutrophils showed a severe reduction in granule contents across all granule subsets. Despite this, Nbeal2-deficient neutrophils had an enhanced phagocyte respiratory burst relative to Nbeal2-expressing neutrophils. This respiratory burst was associated with increased expression of cytosolic components of the NADPH oxidase complex. Nbeal2-deficient NK cells were also dysfunctional and showed ...

Chronic kidney disease (CKD), namely chronic renal insufficiency or chronic renal failure, refers to chronic kidney structure and function disorder caused by various factors. According to GFR (Glomerular filtration rate) index, chronic kidney disease is divided into five stages. Once the CKD patients enter the fifth stage, namely end-stage renal disease (ESRD) commonly known as uremia, and the renal replacement therapy must be conducted.. Hemodialysis (HD) is one of the renal replacement therapy ways to treat acute or chronic renal failure patients. Presently, there are more than 2 million end-stage renal disease (ESRD) patients all over the world who choose the dialysis therapy, and about 90% of them receive hemodialysis. Because of the high hemodialysis expenses, the dialysis patients mainly concentrate in developed countries. ESRD patients on dialysis account for 10%-20% in developing countries, which is far lower than the 80% in developed countries. The population of dialysis patients is ...

Seventy-five consecutive patients with normal platelet counts were investigated for "easy bruising." All had a normal coagulation profile, and all except four were women. None were on aspirin or other antiplatelet agents. Two specific groups could be delineated. In type I (44 patients, mean age, 35), platelet function was normal to supranormal. Megathrombocyte number was elevated in 60% of patients and correlated with the presence of antiplatelet antibody in 30% of patients. In type II (31 patients, mean age, 34), platelet function was abnormal: impaired epinephrine aggregation (primary and secondary wave) in 97%, impaired connective tissue aggregation in 77%, and impaired ADP aggregation in 42%. Megathrombocyte number was elevated in 71%, and antiplatelet antibody was present in 38% of patients. The "easy bruising" syndrome can be differentiated into two categories: type I, in which a platelet abnormality is unlikely, and type II, in which a platelet abnormality exists. Elevated incidence of ...

A carrier is a female who has the genetic mutation for hemophilia on one of her X chromosomes. Carriers with clotting factors levels of less than 50% of normal may have symptoms similar to a male with mild hemophilia. They are often called symptomatic carriers or are diagnosed with mild hemophilia. Approximately one-third of carriers experience bleeding symptoms. By definition, if a woman has clotting factor levels less than 50%, she has mild hemophilia..

gp96 is an endoplasmic reticulum chaperone for multiple Toll-like receptors and integrins. Our lab has generated a conditional gp96 knockout model allowing gp96 to be efficiently deleted from all tissues. Herein we demonstrate that gp96 is a master chaperone for 14 of 17 hematopoietic specific integrins and the critical role for gp96 in normal B cell and T cell development, but not for myeloid cell development. Additionally, we show that gp96 chaperones the GPIb-IX complex in platelets and is critical for normal platelet development and function, and results in a condition that closely resembles human Bernard-Soulier syndrome. Lastly, we report that global deletion of gp96 in mice results in spontaneous inflammatory bowel-like disease and a surprising role for gp96 in Wnt signaling, which is known to regulate intestinal homeostasis. Thus, my thesis work was aimed at understanding the roles and mechanisms of gp96 in (1) hematopoiesis, (2) platelet development and function, and (3) intestinal

He sido una "beauty junkie" incluso desde antes que estuviera de moda esto de tener blog. Siempre me ha gustado el maquillaje high end (el que venden en las tiendas departamentales), y más desde que mi mamá me regaló mi primer quinteto y gloss de Dior.

Por ello, un día decidí que debía compartir un poquito más esta afición escribiendo un blog ...
Fragile X-associated disorders encompass several conditions, which are caused by expansion mutations in the fragile X mental retardation 1 (FMR1) gene. Fragile X syndrome is the most common inherited etiology of intellectual disability and results from a full mutation or ,200 CGG repeats in FMR1. It is associated with developmental delay, autism spectrum disorder, and seizures. Fragile X-associated tremor/ataxia syndrome is a progressive neurodegenerative disease that occurs in premutation carriers of 55-200 CGG repeats in FMR1 and is characterized by kinetic tremor, gait ataxia, parkinsonism, executive dysfunction, and neuropathy ...
Normal primary platelet aggregation requires agonist-mediated activation of membrane GPIIb-IIIa, binding of fibrinogen to GPIIb-IIIa, and cellular events after ligand binding. PAC1 monoclonal antibody distinguishes between resting and activated states of GPIIb-IIIa, and other antibodies preferentially recognize GPIIb (PMI-1) or IIIa (anti-LIBS1) after the binding of fibrinogen or fibrinogen-mimetic peptides, such as GRGDSP. Using these antibodies and platelet flow cytometry, we studied two distinct persistent platelet aggregation abnormalities. Platelets from a thrombasthenic variant, which contained near-normal amounts of GPIIb-IIIa, failed to aggregate or bind PAC1 in response to agonists. In addition, GRGDSP, which binds to normal GPIIb-IIIa without prior cell activation, failed to increase the binding of PMI-1 or anti-LIBS1 to the thrombasthenic platelets, suggesting a primary defect in ligand binding. Chromatography of detergent-solubilized platelets on a KYGRGDS affinity column confirmed ...
TY - JOUR. T1 - Expression and functional characterization of an abnormal platelet membrane glycoprotein Ibα (Met239 → Val) reported in patients with platelet-type yon Willebrand Disease.

Y1 - 1997/7/15. N2 - Platelet-type von Willebrand disease (vWD) is a congenital bleeding disorder characterized by heightened ristocetin-induced platelet aggregation caused by abnormally high affinity between the platelet membrane glycoprotein (GP) Ib/IX complex and von Willebrand factor (vWF). Two distinct point mutations, Gly233 to Val and Met239 to Val, have been reported in GPIbα. We have constructed a recombinant GPIbα fragment containing the latter mutation, Met239 to Val (M239V) and characterized the mutant molecule using two methods, ie, interaction between soluble vWF and immobilized M239V and inhibition of ...
The best-known coagulation factor disorders are the hemophilias. The three main forms are hemophilia A (factor VIII deficiency), hemophilia B (factor IX deficiency or "Christmas disease") and hemophilia C (factor XI deficiency, mild bleeding tendency). Hemophilia A and B are X-linked recessive disorders, whereas Hemophilia C is a much more rare autosomal recessive disorder most commonly seen in Ashkenazi Jews.. Von Willebrand disease (which behaves more like a platelet disorder except in severe cases), is the most common hereditary bleeding disorder and is characterized as being inherited autosomal recessive or dominant. In this disease, there is a defect in von Willebrand factor (vWF), which mediates the binding of glycoprotein Ib (GPIb) to collagen. This binding helps mediate the activation of platelets and formation of primary hemostasis.. Bernard-Soulier syndrome is a defect or deficiency in GPIb. GPIb, the receptor for vWF, can be defective and lead to lack of primary clot formation ...
