Disorders of the peripheral nervous system associated with the deposition of AMYLOID in nerve tissue. Familial, primary (nonfamilial), and secondary forms have been described. Some familial subtypes demonstrate an autosomal dominant pattern of inheritance. Clinical manifestations include sensory loss, mild weakness, autonomic dysfunction, and CARPAL TUNNEL SYNDROME. (Adams et al., Principles of Neurology, 6th ed, p1349)
Inherited disorders of the peripheral nervous system associated with the deposition of AMYLOID in nerve tissue. The different clinical types based on symptoms correspond to the presence of a variety of mutations in several different proteins including transthyretin (PREALBUMIN); APOLIPOPROTEIN A-I; and GELSOLIN.
A tetrameric protein, molecular weight between 50,000 and 70,000, consisting of 4 equal chains, and migrating on electrophoresis in 3 fractions more mobile than serum albumin. Its concentration ranges from 7 to 33 per cent in the serum, but levels decrease in liver disease.
A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits.
A fibrous protein complex that consists of proteins folded into a specific cross beta-pleated sheet structure. This fibrillar structure has been found as an alternative folding pattern for a variety of functional proteins. Deposits of amyloid in the form of AMYLOID PLAQUES are associated with a variety of degenerative diseases. The amyloid structure has also been found in a number of functional proteins that are unrelated to disease.
Peripheral, autonomic, and cranial nerve disorders that are associated with DIABETES MELLITUS. These conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves (VASA NERVORUM). Relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy (see OCULOMOTOR NERVE DISEASES); MONONEUROPATHY; mononeuropathy multiplex; diabetic amyotrophy; a painful POLYNEUROPATHY; autonomic neuropathy; and thoracoabdominal neuropathy. (From Adams et al., Principles of Neurology, 6th ed, p1325)
Peptides generated from AMYLOID BETA-PEPTIDES PRECURSOR. An amyloid fibrillar form of these peptides is the major component of amyloid plaques found in individuals with Alzheimer's disease and in aged individuals with trisomy 21 (DOWN SYNDROME). The peptide is found predominantly in the nervous system, but there have been reports of its presence in non-neural tissue.
An ACUTE PHASE REACTION protein present in low concentrations in normal sera, but found at higher concentrations in sera of older persons and in patients with AMYLOIDOSIS. It is the circulating precusor of amyloid A protein, which is found deposited in AA type AMYLOID FIBRILS.
Diseases of the peripheral nerves external to the brain and spinal cord, which includes diseases of the nerve roots, ganglia, plexi, autonomic nerves, sensory nerves, and motor nerves.
A single-pass type I membrane protein. It is cleaved by AMYLOID PRECURSOR PROTEIN SECRETASES to produce peptides of varying amino acid lengths. A 39-42 amino acid peptide, AMYLOID BETA-PEPTIDES is a principal component of the extracellular amyloid in SENILE PLAQUES.
Accumulations of extracellularly deposited AMYLOID FIBRILS within tissues.
A group of slowly progressive inherited disorders affecting motor and sensory peripheral nerves. Subtypes include HMSNs I-VII. HMSN I and II both refer to CHARCOT-MARIE-TOOTH DISEASE. HMSN III refers to hypertrophic neuropathy of infancy. HMSN IV refers to REFSUM DISEASE. HMSN V refers to a condition marked by a hereditary motor and sensory neuropathy associated with spastic paraplegia (see SPASTIC PARAPLEGIA, HEREDITARY). HMSN VI refers to HMSN associated with an inherited optic atrophy (OPTIC ATROPHIES, HEREDITARY), and HMSN VII refers to HMSN associated with retinitis pigmentosa. (From Adams et al., Principles of Neurology, 6th ed, p1343)
A pancreatic beta-cell hormone that is co-secreted with INSULIN. It displays an anorectic effect on nutrient metabolism by inhibiting gastric acid secretion, gastric emptying and postprandial GLUCAGON secretion. Islet amyloid polypeptide can fold into AMYLOID FIBRILS that have been found as a major constituent of pancreatic AMYLOID DEPOSITS.
A heterogeneous group of sporadic or familial disorders characterized by AMYLOID deposits in the walls of small and medium sized blood vessels of CEREBRAL CORTEX and MENINGES. Clinical features include multiple, small lobar CEREBRAL HEMORRHAGE; cerebral ischemia (BRAIN ISCHEMIA); and CEREBRAL INFARCTION. Cerebral amyloid angiopathy is unrelated to generalized AMYLOIDOSIS. Amyloidogenic peptides in this condition are nearly always the same ones found in ALZHEIMER DISEASE. (from Kumar: Robbins and Cotran: Pathologic Basis of Disease, 7th ed., 2005)
A group of inherited disorders characterized by degeneration of dorsal root and autonomic ganglion cells, and clinically by loss of sensation and autonomic dysfunction. There are five subtypes. Type I features autosomal dominant inheritance and distal sensory involvement. Type II is characterized by autosomal inheritance and distal and proximal sensory loss. Type III is DYSAUTONOMIA, FAMILIAL. Type IV features insensitivity to pain, heat intolerance, and mental deficiency. Type V is characterized by a selective loss of pain with intact light touch and vibratory sensation. (From Joynt, Clinical Neurology, 1995, Ch51, pp142-4)
Ischemic injury to the OPTIC NERVE which usually affects the OPTIC DISK (optic neuropathy, anterior ischemic) and less frequently the retrobulbar portion of the nerve (optic neuropathy, posterior ischemic). The injury results from occlusion of arterial blood supply which may result from TEMPORAL ARTERITIS; ATHEROSCLEROSIS; COLLAGEN DISEASES; EMBOLISM; DIABETES MELLITUS; and other conditions. The disease primarily occurs in the sixth decade or later and presents with the sudden onset of painless and usually severe monocular visual loss. Anterior ischemic optic neuropathy also features optic disk edema with microhemorrhages. The optic disk appears normal in posterior ischemic optic neuropathy. (Glaser, Neuro-Ophthalmology, 2nd ed, p135)
Amyloid P component is a small, non-fibrillar glycoprotein found in normal serum and in all amyloid deposits. It has a pentagonal (pentaxin) structure. It is an acute phase protein, modulates immunologic responses, inhibits ELASTASE, and has been suggested as an indicator of LIVER DISEASE.
Diseases of multiple peripheral nerves simultaneously. Polyneuropathies usually are characterized by symmetrical, bilateral distal motor and sensory impairment with a graded increase in severity distally. The pathological processes affecting peripheral nerves include degeneration of the axon, myelin or both. The various forms of polyneuropathy are categorized by the type of nerve affected (e.g., sensory, motor, or autonomic), by the distribution of nerve injury (e.g., distal vs. proximal), by nerve component primarily affected (e.g., demyelinating vs. axonal), by etiology, or by pattern of inheritance.
A branch of the tibial nerve which supplies sensory innervation to parts of the lower leg and foot.
Endopeptidases that are specific for AMYLOID PROTEIN PRECURSOR. Three secretase subtypes referred to as alpha, beta, and gamma have been identified based upon the region of amyloid protein precursor they cleave.
A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS. (From Adams et al., Principles of Neurology, 6th ed, pp1049-57)
The sequential activation of serum COMPLEMENT PROTEINS to create the COMPLEMENT MEMBRANE ATTACK COMPLEX. Factors initiating complement activation include ANTIGEN-ANTIBODY COMPLEXES, microbial ANTIGENS, or cell surface POLYSACCHARIDES.
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.
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.
Branch of medicine concerned with the prevention and control of disease and disability, and the promotion of physical and mental health of the population on the international, national, state, or municipal level.

The transference of a part of or an entire liver from one human or animal to another.

Transthyretin Leu12Pro is associated with systemic, neuropathic and leptomeningeal amyloidosis. (1/76)

We report a middle-aged woman with a novel transthyretin (TTR) variant, Leu12Pro. She had extensive amyloid deposition in the leptomeninges and liver as well as the involvement of the heart and peripheral nervous system which characterizes familial amyloid polyneuropathy caused by variant TTR. Clinical features attributed to her leptomeningeal amyloid included radiculopathy, central hypoventilation, recurrent subarachnoid haemorrhage, depression, seizures and periods of decreased consciousness. MRI showed a marked enhancement throughout her meninges and ependyma, and TTR amyloid deposition was confirmed by meningeal biopsy. The simultaneous presence of extensive visceral amyloid and clinically significant deposits affecting both the peripheral and central nervous system extends the spectrum of amyloid-related disease associated with TTR mutations. The unusual association of severe peripheral neuropathy with symptoms of leptomeningeal amyloid indicates that leptomeningeal amyloidosis should be considered part of the syndrome of TTR-related familial amyloid polyneuropathy.  (+info)

Phase I trial of dolastatin-10 (NSC 376128) in patients with advanced solid tumors. (2/76)

Dolastatin-10 (dola-10) is a potent antimitotic peptide, isolated from the marine mollusk Dolabela auricularia, that inhibits tubulin polymerization. Preclinical studies of dola-10 have demonstrated activity against a variety of murine and human tumors in cell cultures and mice models. The purpose of this Phase I clinical trial was to characterize the maximum tolerated dose, pharmacokinetics, and biological effects of dola-10 in patients with advanced solid tumors. Escalating doses of dola-10 were administered as an i.v. bolus every 21 days, using a modified Fibonacci dose escalation schema. Pharmacokinetic studies were performed with the first treatment cycle. Neurological testing was performed on each patient prior to treatment with dola-10, at 6 weeks and at study termination. Thirty eligible patients received a total of 94 cycles (median, 2 cycles; maximum, 14 cycles) of dola-10 at doses ranging from 65 to 455 microg/m2. Dose-limiting toxicity of granulocytopenia was seen at 455 microg/m2 for minimally pretreated patients (two or fewer prior chemotherapy regimens) and 325 microg/m2 for heavily pretreated patients (more than two prior chemotherapy regimens). Nonhematological toxicity was generally mild. Local irritation at the drug injection site was mild and not dose dependent. Nine patients developed new or increased symptoms of mild peripheral sensory neuropathy that was not dose limiting. This toxicity was more frequent in patients with preexisting peripheral neuropathies. Pharmacokinetic studies demonstrated a rapid drug distribution with a prolonged plasma elimination phase (t 1/2z = 320 min). The area under the concentration-time curve increased in proportion to administered dose, whereas the clearance remained constant over the doses studied. Correlation analysis demonstrated a strong relationship between dola-10 area under the concentration-time curve values and decrease from baseline for leukocyte counts. In conclusion, dola-10 administered every 3 weeks as a peripheral i.v. bolus is well tolerated with dose-limiting toxicity of granulocytopenia. The maximum tolerated dose (and recommended Phase II starting dose) is 400 microg/m2 for patients with minimal prior treatment (two or fewer prior chemotherapy regimens) and 325 microg/m2 for patients who are heavily pretreated (more than two prior chemotherapy regimens).  (+info)

1H-NMR structural studies of a cystine-linked peptide containing residues 71-93 of transthyretin and effects of a Ser84 substitution implicated in familial amyloidotic polyneuropathy. (3/76)

The Ile-->Ser84 substitution in the thyroid hormone transport protein transthyretin is one of over 50 variations found to be associated with familial amyloid polyneuropathy, a hereditary type of lethal amyloidosis. Using a peptide analogue of the loop containing residue 84 in transthyretin, we have examined the putative local structural effects of this substitution using 1H-NMR spectroscopy. The peptide, containing residues 71-93 of transthyretin with its termini linked via a disulfide bond, was found to possess the same helix-turn motif as in the corresponding region of the crystallographically derived structure of transthyretin in 20% trifluoroethanol (TFE) solution. It therefore, represents a useful model with which to examine the effects of amyloidogenic substitutions. In a peptide analogue containing the Ile84-->Ser substitution it was found that the substitution does not greatly disrupt the overall three-dimensional structure, but leads to minor local differences at the turn in which residue 84 is involved. Coupling constant and NOE measurements indicate that the helix-turn motif is still present, but differences in chemical shifts and amide-exchange rates reflect a small distortion. This is in keeping with observations that several other mutant forms of transthyretin display similar subunit interactions and those that have been structurally analysed possess a near native structure. We propose that the Ser84 mutation induces only subtle perturbations to the transthyretin structure which predisposes the protein to amyloid formation.  (+info)

Role of sympathetic nervous system in cyclosporine-induced rise in blood pressure. (4/76)

To clarify the role of the sympathetic nervous system in the development of cyclosporine A (CsA)-induced rise in blood pressure (BP), the effects of CsA on 24-hour ambulatory BP (ABP) were studied in patients with familial amyloid polyneuropathy (FAP) who underwent a liver transplantation. On the basis of autonomic function tests, patients with absent or mild-to-moderate sympathetic damage (Group A, n=11, age 29 to 43 years, disease duration 2 to 6 years) and patients with severe sympathetic damage (Group B, n=9, age 27 to 38 years, disease duration 3 to 9 years) were identified. Both groups were followed for 1 year. The daily doses of CsA and the CsA whole blood trough levels between the groups did not differ. Pretransplantation values of daytime and nighttime ABP were, respectively, 117+/-8/76+/-7 mm Hg and 108+/-12/68+/-9 mm Hg in group A and 107+/-6/66+/-4 mm Hg (P<0.05 group A versus group B) and 102+/-6/62+/-4 mm Hg in group B. In response to CsA, BP increased in all patients, but more so in patients of group B than in patients of group A. One year after transplantation, daytime and nighttime ABP had increased by 6+/-9/3+/-11% and 12+/-10/14+/-14% in group A and by 12+/-6/13+/-10% (P<0.05) and 21+/-11/27+/-21% (P<0.01) in group B. In both groups, the increase in nighttime ABP was greater than the increase in daytime ABP, which resulted in an attenuation or, even, a reversal of the diurnal BP rhythm. Because the rise in BP was greater in patients with more advanced sympathetic dysfunction, the sympathetic nervous system appears to counteract the CsA-induced rise in BP rather than causing it. This implies involvement of factors other than sympathetic activation in the pathogenesis of CsA-induced rise in BP in patients with familial amyloid polyneuropathy.  (+info)

Identification of a new transthyretin variant (Ile49) in familial amyloidotic polyneuropathy using electrospray ionization mass spectrometry and nonisotopic RNase cleavage assay. (5/76)

Mutation of the transthyretin (TTR) plasma protein and gene in a Japanese patient with amyloid polyneuropathy was investigated by electrospray ionization mass spectrometry (ESI-MS) and nonisotopic RNase cleavage assay (NIRCA), respectively. ESI-MS analysis showed normal TTR peaks and additionally a variant TTR with 12-dalton-higher molecular weight than normal TTR. NIRCA suggested that the mutation existed near either the 5' or 3' end of exon 3. Direct DNA sequencing revealed both a normal ACC (threonine) and a variant ATC (isoleucine) at codon 49, which was located near the 5' end of exon 3. The molecular weight shift of this mutation was 12 D, consistent with the result of ESI-MS.  (+info)

Regulation of neural differentiation by normal and mutant (G654A, amyloidogenic) gelsolin. (6/76)

Gelsolin belongs to a family of proteins that modulate the structural dynamics of cytoskeletal actin. Gelsolin activity is required for the redistribution of actin occurring during membrane ruffling, cell crawling, and platelet activation. A point mutation (G654A) in the gelsolin gene causes a dominantly inherited systemic amyloidosis called familial amyloidosis of the Finnish type (FAF). This disease is characterized by a cranial neuropathy that cannot be explained solely by amyloid deposits. To address the question of whether gelsolin has a specific role in neural cell development, we transfected cDNA for wild type and G654A point-mutated gelsolin into a neural cell line, Paju, which can be induced to differentiate by treatment with phorbol 12-myristate 13-acetate. Overexpressed wild type gelsolin inhibited neural differentiation whereas mutated gelsolin did not, indicating that appropriate gelsolin activity is essential for neural sprouting. The G654A mutant gelsolin induced stabilization of F-actin and reduced the plasticity of neural development. This provides a novel etiopathogenetic mechanism for the neuronal dysfunction in FAF.  (+info)

Two pairs of proven monozygotic twins discordant for familial amyloid neuropathy (FAP) TTR Met 30. (7/76)

Twin studies are an important tool in medical genetics for the evaluation of the relative roles of genetic and non-genetic factors in several diseases. Familial amyloidotic polyneuropathy type I (FAP-I), TTR Met 30, was present in two sets of proven monozygotic (MZ) twins, one from Majorca and the other from Portugal. Monozygosity was established by analysis of DNA polymorphisms. Both pairs were discordant for age at onset and some clinical manifestations of FAP-I. We reviewed the differences in age at onset and clinical features in both sets and in two other pairs of presumed MZ twins with FAP-I and compared them with those in MZ twin pairs with other Mendelian disorders, such as neurofibromatosis type 1, Huntington's disease, facioscapulohumeral muscular dystrophy, and myotonic dystrophy. We conclude that, in addition to the postulated modifying genes, there must be a significant contribution from non-genetic factors to the phenotypic variability of FAP-I (age at onset and clinical expression), either because of environmental differences or stochastic events during (or after) the twinning process.  (+info)

Late-onset familial amyloid polyneuropathy type I (transthyretin Met30-associated familial amyloid polyneuropathy) unrelated to endemic focus in Japan. Clinicopathological and genetic features. (8/76)

Clinicopathological and genetic features were assessed on 35 Japanese families affected by late-onset familial amyloid polyneuropathy type I (transthyretin Met30-associated familial amyloid polyneuropathy, FAP TTR Met30) whose siblings were unrelated to endemic Japanese foci. In these patients (50 years or older), the most common initial symptom was paraesthesias in the legs. Autonomic symptoms were generally mild and did not seriously affect daily activities. The male-to-female ratio was extremely high (10.7 : 1). A family history was evident in only 11 out of 35 families, and other patients were apparently sporadic. The rate of penetrance was very low. Symptomatic siblings of familial cases showed a late age of onset, male preponderance and clinical features similar to those of the probands. Asymptomatic carriers, predominantly female, were detected relatively late in life. The geographical distribution of these late-onset, FAP TTR Met30 cases was scattered throughout Japan. In three autopsy cases and 20 sural nerve biopsy specimens, neurons in sympathetic and sensory ganglia were relatively preserved. Amyloid deposition was seen in the peripheral nervous system, particularly in the sympathetic ganglia, dorsal root ganglia and proximal nerve trunks such as sciatic nerve. These abnormalities were milder than those seen in typical early-onset FAP TTR Met30, as observed in two Japanese endemic foci of this disease. While axonal degeneration was prominent in myelinated fibres, resulting in severe fibre loss, unmyelinated fibres were relatively preserved. Our cases of late-onset FAP TTR Met30 showed features distinct from those of typical early-onset FAP TTR Met30 that occurred in the two Japanese endemic foci. Factors responsible for clinicopathological differences between these two forms of FAP TTR Met30 need to be identified.  (+info)

Ocular manifestations in 37 patients with FAP type I (Met30) were presented through long term follow up in Arao district, Kumamoto, Japan, which is one of the most well known endemic areas for this disease.4 16 Statistical analysis revealed that ACV showed the highest incidence among the ocular disorders. The incidence of KCS, pupillary abnormality, vitreous opacity, and glaucoma followed ACV. It is well documented that amyloid deposition is commonly found in the perivascular area2 3 so ACV may reflect the microscopic changes in the vessels.. It is believed that unmyelinated fibres, which correspond to autonomic nerve fibres, are first impaired during the course of the disease.17 In fact, many ordinary FAP patients start to develop autonomic dysfunctions before sensory dominant polyneuropathy.1 We previously reported that ACV are possibly induced by autonomic nervous dysfunction as well as amyloid deposition around the vessels themselves because all patients we examined with pandysautonomia ...
Familial amyloid polyneuropathy type I is an autosomal dominant disorder caused by mutations in the transthyretin (TTR) gene; however, carriers of the same mutation exhibit variability in penetrance and clinical expression. We analyzed alleles of candidate genes encoding non-fibrillar components of TTR amyloid deposits and a molecule metabolically interacting with TTR [retinol-binding protein (RBP)], for possible associations with age of disease onset and/or susceptibility in a Portuguese population sample with the TTR V30M mutation and unrelated controls. We show that the V30M carriers represent a distinct subset of the Portuguese population. Estimates of genetic distance indicated that the controls and the classical-onset group were furthest apart, whereas the late-onset group appeared to differ from both. Importantly, the data also indicate that genetic interactions among the multiple loci evaluated, rather than single-locus effects, are more likely to determine differences in the age of ...
TY - JOUR. T1 - Complement activation in acquired and hereditary amyloid neuropathy. AU - Hafer-Macko, Charlene E.. AU - Dyck, Peter J. AU - Koski, Carol Lee. PY - 2000. Y1 - 2000. N2 - The pathogenesis of the axonal degeneration in acquired or hereditary amyloidosis is unknown. In this immunohistochemistry study, we examined 20 sural nerve biopsies from individuals with amyloid neuropathy (14 acquired and 6 hereditary) for evidence of complement activation. Complement activation products were detected on and around amyloid deposits within peripheral nerves. We found no difference in the extent, location or pattern of complement activation products between the 2 forms of amyloidosis. The presence of early classical pathway activation markers in the absence of antibody in hereditary cases suggests an antibody-independent activation of the classical pathway through binding of C1q. The lack of Factor Bb-suggested alternative pathway activation was not significant in these cases. The detection of ...

Familial Amyloid Polyneuropathy (FAP) is a rare, hereditary disease caused by mutations in the transthyretin (TTR) protein. TTR is made by the liver and secreted into the blood. TTR mutations cause it to misfold and deposit in multiple organs causing FAP.. IONIS-TTR Rx is an antisense drug that is designed to decrease the amount of mutant and normal TTR made by the liver. It is predicted that decreasing the amount of TTR protein will result in a decrease in the formation of TTR deposits, and thus slow or stop disease progression.. The purpose of this study is to determine if IONIS-TTR Rx can slow or stop the nerve damage caused by TTR deposits. This study will enroll late Stage 1 and early Stage 2 FAP patients.

The most specific ocular manifestations of ATTR-FAP are deposits on lens anterior capsule and pupillary border, scalloped pupil and vitreous amyloidosis and the most severe one is glaucoma.. Amyloid deposits on anterior lens surface are central, disciform opacities with more dense border. Amyloid deposits on pupillary border are irregularities of white membranous material. Scalloped pupil, an irregular outlines and fringed edges of pupil, is pathognomonic of ATTR-FAP.. Peculiar vitreous opacities are the most common specific change of late onset TTR Met30Val population. There are four types of amyloid vitreous opacities: pseudopodia lentis, fibrils, spherical opacities and pre-vascular opacities. Pseudopodia lentis and typical fibrils, since numerous and dense, are also pathognomonic.. Dry eye is a common ocular change in FAP but a non specific. Signs of keratoconjunctivitis sicca like diminution of Break Up Time and punctata epitheliopathy are frequent and complications like corneal ...

N2 - Aims: Transthyretin (TTR)-related familial amyloidotic polyneuropathy (FAP) is characterized by the systemic accumulation of amyloid fibrils caused by amyloidogenic. Our previous studies demonstrated that albumin played a role in the inhibition of TTR amyloid-formation. The aim of this study was to evaluate the effect of albumin on TTR disposition and tissue deposition in vivo. Main methods: For pharmacokinetic studies, recombinant wild-type TTR (rTTR) and recombinant amyloidogenic TTR Val30Met (rATTR V30M) were labeled with iodine and administered to Sprague-Dawley rats and ...

Per Hammarstr�m, Frank Schneider, and Jeffery W. Kelly http://sageke.sciencemag.org/cgi/content/abstract/sageke;2001/2/or18 Abstract: Science 293, 2459-2462 (2001).. The transthyretin (TTR) amyloid diseases, representative of numerous misfolding disorders, are of considerable interest because there are mutations that cause or suppress disease. The Val30>Met30 (V30M) TTR mutation is the most prevalent cause of familial amyloid polyneuropathy in heterozygotes, whereas a Thr119>Met119 (T119M) mutation on the second TTR allele protects V30M carriers from disease. Here, we show that the incorporation of one or more T119M TTR subunits into a predominantly V30M tetramer strongly stabilized the mixed tetramer against dissociation. Dissociation is required for amyloid formation, so these findings provide a molecular explanation for intragenic trans-suppression of amyloidosis. The data also suggest a potential therapeutic strategy, provide insight into tissue-specific deposition and amyloid composition, ...
Transthyretin familial amyloid polyneuropathy (TTR-FAP) is a progressive, fatal, inherited disorder first identified in Portugal and now recognized in all continents. Over the past decade, thanks to the availability of the genetic test, our knowledge on the range of clinical expressions of this disorder has expanded, including different patterns and progression rates of the neuropathy, as well as aspects of the cardiomyopathy, which can be prominent. In the mean time, new tools are being developed to detect earlier TTR amyloid deposition such as cardiac scintigraphy with technetium-labelled pyrophosphate tracers or small nerve fiber alterations from skin biopsies, or using neurophysiological approaches as well as magnetic resonance neurography (MRN ...

Val30Met mutation accounts for the majority of the patients with large endemic foci especially in Portugal, Sweden and Japan. However, more than one hundred other mutations have been described worldwide. A great phenotypic variability among patients with late- and early-onset has been reported. Objective: To present a detailed report of TTR-FAP patients diagnosed in our tertiary neuromuscular center, in a 20-year period. Methods: Clinical informations were gathered through the database of our center. …Results: The study involved 76 individuals carrying a TTR-FAP mutation. Three phenotypes were identified, each ...
OBJECTIVE: To systematically study peripheral nerve morphology in patients with transthyretin (TTR) amyloidosis and TTR gene mutation carriers using high-resolution ultrasonography (US). METHODS: In this prospective cross-sectional study we took a structured history, performed neurological examination, and measured peripheral nerve cross-sectional areas (CSAs) bilaterally at 28 standard locations using US. Demographic and US findings were compared to controls. RESULTS: Peripheral nerve CSAs were significantly larger in 33 patients with familial amyloid polyneuropathy (FAP) compared to 50 controls, most dramatically at the common entrapment sites (median nerve at the wrist, ulnar nerve at the elbow), and in the proximal nerve segments (median nerve in the upper arm, sciatic nerve in the thigh ...
The disease starts with a feeling of increased clumsiness. Spilling a cup of coffee. Stumbling on the stairs. Having accidents that are easy to dismiss-everyone trips now and then.

There are some interesting points in the study from the Sun lab that seem to add to general themes found in diseases associated with amyloid aggregation. In all of these diseases, inclusions consisting of an endogenously produced protein mark the progression of the disease. What exactly causes the previously soluble and physiological form of the protein to change conformation into a pathological form and aggregate is in most cases unclear.. In the case of transthyretin (TTR), a serum protein involved in familial amyloidotic polyneuropathy, a destabilization event induced by either a missense mutation or an external insult leads to depolymerization of the natively tetrameric protein, which then leaves it open to amyloidogenic polymerization (Quintas et al., 1999). The native form, stabilized by its natural ligand thyroxin, is aggregation-resistant. Our lab has recently discovered that a very similar situation can be found for α-synuclein (αS), a mostly neuronally expressed protein of unknown ...

This is an open-label, multicenter, international study designed to determine TTR stabilization as well as Fx-1006A safety and tolerability, and its effects on clinical outcomes in patients with non-V30M TTR amyloidosis. Strong pre-clinical and clinical evidence support a daily dose of 20 mg of Fx-1006A to be the optimum dose to achieve stabilization of tetrameric TTR in ATTR-PN patients. Since disease presentation is similar between V30M and non-V30M TTR mutations associated with ATTR-PN and Fx-1006A has been shown to stabilize wild-type and V30M TTR in vitro and ex vivo, the present study is being conducted to determine the effects of Fx-1006A on TTR stabilization in ATTR-PN patients with TTR mutations other than V30M. Safety and exploratory efficacy of Fx-1006A administered once daily for 12 months will also be evaluated in this patient population. This is an open-label, multicenter, international study designed to determine TTR stabilization as well as Fx-1006A safety and tolerability, and ...

The pathophysiology of the hemodynamic responses to postural stress in familial amyloidotic polyneuropathy (FAP) remains to be elucidated. The aim of the study was to evaluate hemodynamic responses after tilt reversal in FAP. Systolic blood pressure (BP) and heart rate variability (HRV) were analyzed in the baseline, 70° upright position, and after tilt reversal in 15 FAP patients and 14 healthy controls. Beat-to-beat BP was recorded with a Finapres device. Maximum systolic BP after tilt reversal was increased with 22±13 mm Hg in FAP patients as compared with baseline (BP overshoot), whereas controls showed a significantly lower BP overshoot (8±6 mm Hg, P,0.001). In all states, total spectral power and the power of the low and high frequency components were all significantly lower than those of the controls (P,0.01). In a linear regression analysis adjusted for age, we found a significant inverse relation between BP overshoot and HRV (total spectral power, power of the low-frequency and ...
BACKGROUND: This study investigated whether a relationship exists between the presence of de novo antibodies and the clinical manifestations of familial amyloidotic polyneuropathy (FAP). METHODS: Serum samples were collected from 25 Japanese and 6 Swedish FAP amyloidogenic transthyretin (ATTR) Valine30Methionine (V30M) patients, 4 asymptomatic Japanese ATTR V30M gene carriers, and 24 Japanese healthy volunteers. Study methods included enzyme-linked immunosorbent assay (ELISA) and mass spectrometry. RESULTS: Three Japanese and 5 Swedish patients had significantly higher levels of antibodies against ATTR than did healthy volunteers and asymptomatic gene carriers (P,0.05). All 8 patients with higher antibody levels were late-onset cases. The ratio of wild-type TTR to ATTR V30M in serum from the high-antibody group was higher than that of the low-antibody group. ELISA results revealed two epitopes at positions 24-35 and 105-115 of ATTR V30M. We found a significant positive correlation between levels ...
Familial transthyretin amyloid polyneuropathy. Curator: Larry H. Bernstein, MD, FCAP. LPBI. First-Ever Evidence that Patisiran Reduces Pathogenic, Misfolded TTR Monomers and Oligomers in FAP Patients. We reported data from our ongoing Phase 2 open-label extension (OLE) study of patisiran, an investigational RNAi therapeutic targeting transthyretin (TTR) for the treatment of TTR-mediated amyloidosis (ATTR amyloidosis) patients with familial amyloidotic polyneuropathy (FAP). Alnylam scientists and collaborators from The Scripps Research Institute and Misfolding Diagnostics, Inc. were able to measure the effects of patisiran on pathogenic, misfolded TTR monomers and oligomers in FAP patients. Results showed a rapid and sustained reduction in serum non-native conformations of TTR (NNTTR) of approximately 90%. Since NNTTR is pathogenic in ATTR amyloidosis and the level of NNTTR reduction correlated with total TTR knockdown, these results provide direct mechanistic evidence supporting the therapeutic ...

The L55P transthyretin (TTR) familial amyloid polyneuropathy-associated variant is distinct from the other TTR variants studied to date and the wild-type protein in that the L55P tetramer can dissociate to the monomeric amyloidogenic intermediate and form fibril precursors under physiological conditions (pH 7.0, 37 degrees C). The activation barrier associated with L55P-TTR tetramer dissociation is lower than the barrier for wild-type transthyretin dissociation, which does not form fibrils under physiological conditions. The L55P-TTR tetramer is also very sensitive to acidic conditions, readily dissociating to form the monomeric amyloidogenic intermediate between pH 5.5-5.0 where the wild-type TTR adopts a nonamyloidogenic tetrameric structure. The formation of the L55P monomeric amyloidogenic intermediate involves subtle tertiary structural changes within the beta-sheet rich subunit as discerned from Trp fluorescence, circular dichroism analysis, and ANS binding studies. The assembly of the ...
RESULTS. 3 patients received a domino graft (from a donor transplanted for familial amyloidotic polyneuropathy); 2 a living related donor graft and 2 a cdaver graft. 5 of the 7 are alive, and as the presenter said 4 are alive and well, but post transplant experience can have complications which are described below. The average followup time for these patients is 12.8 months (4-30 months). The longest a patient is alive who is doing well is 30 months. In general transplant experience is that patients with hepatitis B have better outcomes than patients with hepatitis C. 3 patients are doing relatively well. The study presenter said 4 of the 7 patients have shown dramatic improvement. 1 patient is in good condition at month 30 and is HCV negative. a second patient has F1 fibrosis at month 12 of followup with low or undetectable HIV RNA and in good condition. A third patient is in good condition at month 18 of followup. Three patients are not doing well. Another patient is alive with F3 fibrosis ...

The disease phenotype of transthyretin (TTR) is dramatically influenced by single point mutations in the TTR gene. Herein, we report on a novel mutation D99N (Asp99Asn) in TTR found in a Danish kindred. None of the family members carrying this mutation have so far shown any clinical signs of amyloidosis. One carrier found compound heterozygous for TTR D99N and L111M (Leu111Met) associated with cardiac amyloid is asymptomatic (42 years). Disease severity can often be linked to both the kinetics of fibril formation and the degree of destabilisation of the native state. In this study, we show that the thermodynamic stability and rate of tetramer dissociation of the variant TTR D99N is unchanged or slightly more stable than wild type (WT) TTR. Furthermore, the in vitro fibrillation kinetics of the variant reveals an unchanged or slightly suppressed tendency to form fibrils compared to WT. Thus, the in vitro experiments support the lack of clinical symptoms observed so far for the TTR D99N carriers. ...

The efficacy of the IgG1κ c11-1F4 mAb to accelerate amyloidolysis in our in vivo amyloidoma model was compared with that of the murine parent. Because the 22C1-, 22C5-, and 22D2-derived c11-1F4 preparations exhibited equivalent reactivity with amyloid and there were limited quantities of each, the three were combined and used in our in vivo experiments. Given the relatively large amount of amyloid extract required to produce a readily palpable amyloidoma (dry weight, 100 mg) and the scarcity of autopsy-derived samples, the numbers of animals used in each study was necessarily restricted to one pair of mice. In the first experiment, four sets were injected s.c. with a 1-ml volume of solution containing 100 mg of a human ALκ extract (Ref. 19 ; patient HIG) that was comprised of fragments (∼16 and 18 kDa) representing the major portion of the amyloidogenic precursor κ1 light chain (BJP, HIG), as demonstrated by SDS-PAGE, Western blot, and chemical analyses. By dot blot, the c11-1F4 mAb, as ...
