Abstract
Prion protein (PrP) is a protein closely associated with the transmission of scrapie and Creutzfeldt-Jakob disease (CJD). Kuru plaques are composed of this protein. PrP33-35 is converted to protease-resistant PrP27-30 by proteinase K digestion. It has not yet been determined which of these PrPs is present in kuru plaques in vivo. Accordingly we synthesized two peptides (peptide-N and peptide-M) that, respectively, corresponded to the protease-sensitive and protease-resistant portions of PrP33-35, based on the amino acid sequence deduced from human PrP cDNA. These two synthetic peptides were used to immunize rabbits and produce antisera (anti-N and anti-M). Both antisera stained kuru plaques in a patient with Gerstmann-Sträussler syndrome and one with CJD. Peptide-N has an amino acid sequence which does not exist in PrP27-30. Staining of kuru plaques by the antiserum against peptide-N indicated that the entire molecule, including the N-terminal portion of PrP33-35, was deposited in the kuru plaques.

Abstract
It was difficult to make a definite pathological diagnosis in a 73-year-old man with Creutzfeldt-Jakob disease (CJD) due to extensive amyloid angiopathy which lacked any severe spongiform changes. Immunostaining using anti-prion protein (PrP) antibody revealed fine granular deposits in the gray matter, after hydrolytic autoclaving pretreatment on tissue sections. Western blotting also revealed an abnormal isoform of PrP, but PrP gene analysis did not show any abnormalities. The primary transmission experiments were repeated three times and induced spongiform encephalopathy in a few mice after a long incubation period.

Abstract
The distribution of swollen neurons and the presence of a phosphorylated neurofilament protein (NFP) epitope in these cells were studied in six cases of Creutzfeldt-Jakob disease (CJD). Swollen neurons are widely distributed in the cerebral cortex and are most abundant in the cingulate and parahippocampal gyri. They are more numerous in the panencephalopathic type of CJD than in the subacute spongiform encephalopathic type. A phosphorylated epitope of NFP was detected in the perikarya of swollen neurons by an immunocytochemical method using a series of monoclonal antibodies that distinguish phosphorylated and nonphosphorylated epitopes of NFP. This abnormal distribution of phosphorylated NFP epitopes indicates that the process of NFP phosphorylation is altered in neurons affected by CJD. This investigation, in accordance with previous studies, suggests that the abnormal post-translational modification of the neurofilament may play an important role in the pathogenesis of several neurodegenerative disorders.

Abstract
We describe the antigenic properties and detection of a normal isoform of scrapie-associated precursor protein (PrP33-35C) in normal, and both normal and scrapie isoforms in scrapie- or Creutzfeldt-Jakob disease (CJD)-infected mouse, hamster, and human brains, using a variety of specific antibodies. Polyclonal antibodies raised against mouse and hamster PrP27-30 and against a synthetic peptide of the N-terminal sequence of this protein were used as immunologic probes. PrP27-30 purified as a primary immunogen corresponded to the lower molecular mass peptide, with Mr between 9.3 and 13.5 kd as estimated by size-exclusion high-pressure liquid chromatography. ELISA and immunoblot techniques demonstrated that antibodies recognized homologous antigens as well as precursor proteins from brains (PrP33-35C) and the scrapie isoform of scrapie-associated proteins (PrP33-35Sc/CJD and PrP27-30) from scrapie- and CJD-infected brains. The normal, scrapie, and CJD isoforms of scrapie-associated proteins share common epitopes with varying degrees of interspecies homology. Specific antigen detected in neurons indicated that these proteins are synthesized primarily in these cells. In infected brains, extracellular amyloid deposits formed by the scrapie isoform of PrP protein also strongly reacted with anti-PrP antibodies.

Abstract
Antibodies reacting with neurofilament proteins were detected by indirect immunofluorescence in the sera from 6 out of 10 patients with verified Creutzfeldt-Jakob disease (CJD), in 4 out of 8 cases of Alzheimer's disease (AD), in a variable percentage (29.4-42.8%) of sera from patients (n = 46) with other dementias of organic or infectious origin and in 5 out of 30 asymptomatic relatives of CJD patients. The occurrence of this antibody did not correlate with the duration or with any other clinical manifestation of CJD. The applicability of the test as differential-diagnostic marker appears limited. The later development of CJD and mental or nervous disease in 3 of 5 asymptomatic relatives with positive serological reaction suggest that the method although nonspecific, may be of certain value in the search for persons at higher risk to develop a degenerative disorder of CNS.

Abstract
Creutzfeldt-Jakob disease (CJD) and scrapie are degenerative neurological diseases caused by unusual infectious pathogens. The term prion has been introduced to underscore the apparent distinctness of these agents from viruses and viroids. The only macromolecule shown to be associated with the infectious agent, the CJD or scrapie prion protein (PrPCJD or PrPSc, respectively), is encoded by the same gene as a normal cellular protein. In several studies biochemical differences have been reported in PrPScs derived from a common host species infected with different putative strains of the scrapie agent, suggesting agent-specific characteristics independent of the host. We analyzed various agent-host combinations by Western blotting of PrPs that were separated by size or charge. The profile of immunoreactive proteins for CJD prions isolated from mice, guinea pigs, and humans appeared distinct. Importantly, PrPCJDS purified from a human brain and from the corresponding first-passage mouse brains were clearly distinguishable. PrPCJDs isolated from CJD prions propagated in NAMRU or B10.Q mice, which are homozygous for a short-incubation-time gene; from the short-incubation-time backcross progeny of (B10.Q x I/LnJ)F1 x B10.Q; or from NAMRU mice inoculated with I/LnJ prions were identical to each other but distinguishable from those of I/LnJ mice, which are homozygous for the long-incubation-time gene. The PrPs from human CJD and ovine scrapie propagated in the same mouse strain appeared the same, but they were distinct from the same isolate of scrapie passaged in hamsters. Lastly, PrPScs purified from five different strains of scrapie propagated in C57BL mice were identical, including strains, ME7 and 139A, which were previously reported to be distinct. This evidence does not support, although it does not exclude, agent-mediated characteristics independent of host-mediated ones for scrapie and CJD.

Abstract
Amyloid plaques have been found in the brains of some patients with Creutzfeldt-Jakob disease (CJD) and all patients with Gerstmann-Sträussler syndrome (GSS). We examined paraffin sections from 45 patients with CJD or GSS and from 51 patients with other neurologic diseases, using an antiserum against GSS amyloid plaque cores. The GSS amyloid plaque core antiserum revealed not only birefringent amyloid plaques but also small plaques that cannot be detected by the staining with Congo red dye. Positive immunolabeling was demonstrated in 59% of 34 Japanese patients with CJD, in 100% of 11 patients with GSS, and in none with other neurologic diseases. All cases of CJD of short duration (less than 11 months) were evaluated as being negative, and 95% of 21 long survivors (over 12 months) were positive. This immunohistochemical approach revealed that amyloid plaque is a hallmark of CJD with a long clinical course.

Abstract
Protease-resistant fibril proteins purified from Spiroplasma mirum and from Creutzfeldt-Jakob disease-infected brain tissues reacted with antisera to scrapie-associated fibrils on Western immunoblot analysis. These data suggest that there are conformational similarities among spiroplasma proteins and infection-specific proteins of the transmissible spongiform encephalopathies.

Abstract
Genetically athymic and asplenic (Lasat), athymic (Nude), asplenic (Dh) or normal littermate (Hetero) mice with a BALB/c genetic background were injected either intracerebrally or intraperitoneally with a 1% or 10% homogenate of mouse brains infected with the Fukuoka 1 strain of the Creutzfeldt-Jakob disease (CJD) agent. As there were no significant differences in incubation periods among the five groups (Lasat, Nude, Dh, Hetero and BALB/c) inoculated with the same dilution, via the same route, it was concluded that cell-mediated immunity dependent on the thymus plays no significant role in host defence against the CJD agent, and the spleen, a critical site of agent replication, is apparently not an obligatory source from which infection spreads to the central nervous system.

Abstract
Antisera raised in rabbits and also for the first time in mice against scrapie-associated fibril (SAF) protein from hamster brain have been quantified by a modified ELISA technique (NC-ELISA) and used for a detailed analysis of SAF proteins obtained from hamster, mouse, and from patients who died of Creutzfeldt-Jakob disease. The antisera predominantly detected five bands in a Western blot analysis with apparent molecular weights of about 26000 (26K), 24K, 20K, 18K and 16K. By gel electrophoresis these antigens seem to be identical in mouse, hamster and man. The amount of material in the various bands, however, varies according to host or agent. In control materials from healthy brain SAF protein was found to be absent even when this material was used in a 50-fold excess compared to diseased brain.

Abstract
Sera from 46 chimpanzees with spongiform encephalopathy (18 kuru, 28 Creutzfeldt-Jakob disease) and sera from 12 sheep with natural scrapie were tested for reactivity with immunoblots of neurofilament preparations obtained from mouse brain. The sera from the chimpanzees reacted mainly with the 200- and 150-kDa proteins of the neurofilament triplet and less frequently with the 70-kDa component of the triplet and with a 62-kDa neurofilament-associated protein. In contrast, the sera of sheep with natural scrapie reacted exclusively against the 62-kDa protein. The specificity of the reactions was established by comparison of sera reactivities with those of rabbit and mouse polyclonal antibodies and mouse monoclonal antibody to neurofilament proteins.

Abstract
Scrapie of sheep and goats as well as Creutzfeldt-Jakob disease (CJD) of humans are neurologic disorders caused by slow infectious pathogens. The novel molecular properties of the pathogen causing scrapie have prompted introduction of the term "prion" to denote a small proteinaceous infectious particle that resists inactivation by nucleic acid-modifying procedures. Antiserum to the major hamster scrapie prion protein (PrP 27-30) was found to cross-react with murine CJD proteins. The CJD proteins had molecular weights similar to those observed for scrapie prion proteins as determined by NaDodSO4 gel electrophoresis. In addition, the CJD proteins were resistant to digestion by proteinase K and appear to polymerize into rod-shaped particles. The purification procedure developed for scrapie prions was found to be useful in purifying the CJD agent. Purification of the two infectious pathogens by virtually identical procedures provided further evidence for similarities in their molecular structures. We conclude that the molecular and biologic properties of the CJD agent are sufficiently similar to those of the scrapie prion protein that CJD should be classified as a prion disease.

Abstract
A total of 529 sera from patients with a wide variety of neurological and non-neurological diseases, and 101 sera from healthy control subjects, were examined by indirect immunofluorescence for the presence of autoantibodies to neurofilament antigens. Antibodies were found in approximately 50% of sera from patients with spongiform encephalopathies, 15-30% of sera from patients with other neurological and non-neurological diseases, and 7% of sera from healthy controls. The antigenic stimulus to these autoantibodies in very diverse disease processes is unknown, but as presently assayed, they are not of sufficient specificity to be useful as an aid to clinical diagnosis.

Abstract
Genetic control of experimental scrapie and Creutzfeldt-Jakob disease (CJD) was studied in inbred strains of mice by measuring the times from intracerebral inoculation with the agents to the onset of neurological dysfunction. Every strain of mice examined was susceptible to infection; however, a wide range of incubation times was found for both scrapie and CJD. New Zealand (NZ) mice, which eventually develop an autoimmune disorder, were inoculated intracerebrally with 10(6) ID50 units of the scrapie agent in a Chandler isolate. NZW mice showed incubation periods of less than 95 days; this is the shortest period recorded for any murine host with scrapie. In NZB and NZB X W F1 mice, the incubation periods were approximately 130 days and were similar to those in BALB/c and C57BL mice. Male and female NZ mice exhibited scrapie incubation periods of the same length. Similar results were obtained when B10.Q and C57BL/6J mice were inoculated intracerebrally with 10(4) ID50 units of the CJD agent in a K.Fu. isolate. These observations define a genetic locus or loci controlling the length of scrapie and CJD incubation periods; alleles coding for longer incubation times appear to be autosomal dominant. When congenic mice with a C57BL/10J background differing only in their H-2 haplotypes were studied, the results showed that the D subregion of the H-2 complex played a central role in controlling the length of the CJD incubation period. The q allele at the D subregion resulted in shorter incubation times, whereas the d allele resulted in long incubation times. The p, s, b, and k alleles gave intermediate incubation times. We propose the symbol PID-1 for designating this genetic locus which is located within the D subregion of the major histocompatibility (H-2) complex on murine chromosome 17. In addition, observations on congenic mice provide evidence for the influence of sex on CJD incubation periods. In some strains of inbred mice, males showed significantly shorter incubation periods compared with those for females with experimental CJD. These studies with inbred mice have defined previously unrecognized genes that control the length of scrapie and CJD incubation periods.

Abstract
Heterogeneic autoantibodies against axonal neurofilament proteins of mature mouse neurons grown in vitro were detected by the indirect immunofluorescence technique in 12.7% (9 of 71) of the sera from nonhuman primates infected with kuru, in 14.5% (17 of 117) and 4% (1 of 25), respectively, of the sera from nonhuman primates and laboratory rodents infected with Creutzfeldt-Jakob disease, and in 35% (7 of 20) of the sera from sheep naturally infected with scrapie. Autoantibody titers ranged from 1:16 to 1:512 in Creutzfeldt-Jakob disease-infected animals, 1:32 to 1:512 in kuru-infected animals, and 1:64 to 1:1,024 in sheep with natural scrapie. The sera from 11 monkeys and 17 hamsters infected with scrapie and from 19 chimpanzees inoculated with brain tissues from humans with other neurological diseases did not contain autoantibodies. Of the 41 chimpanzees with Creutzfeldt-Jakob disease, 6 had autoantibodies against neurofilament proteins before experimental inoculation, whereas 6 others developed autoantibodies after inoculation, 4 developed autoantibodies during the asymptomatic phase, and 2 developed autoantibodies during the terminal clinical phase. Of the 48 chimpanzees with kuru, 2 had autoantibodies before inoculation, 6 developed autoantibodies after inoculation, 3 developed autoantibodies during the asymptomatic phase, and 3 developed autoantibodies during the terminal clinical phase. Among the normal nonhuman primate controls, 4.6% (9 of 195) had autoantibodies. In contrast, no autoantibodies were detected in 49 control rodents and 13 control sheep. The increased incidence of autoantibodies against neurofilament proteins in animals with kuru, Creutzfeldt-Jakob disease, and scrapie constitutes the first evidence of an immunological reaction in this group of atypical infections caused by unconventional viruses and suggests that neurofilaments may be involved in pathogenesis.

Abstract
A rapid and technically simple method for demonstrating anti-neurofilament antibodies using longitudinal sections of rat spinal cord as substratum and indirect immunofluorescent technique is reported. The results compare well with those obtained by the technically more difficult and time-consuming methods using as substratum central neurons cultivated in vitro. A total of 195 serum specimens from different neurological disorders and healthy subjects were studied. Immunofluorescent autoantibodies to neurofilaments were found in specimens of serum from patients with Creutzfeldt-Jakob disease (CJD), kuru, amyotrophic lateral sclerosis, parkinsonism dementia (Guam), Alzheimer's disease, and multiple sclerosis but in higher frequency in CJD and kuru than in the other disease or in healthy control subjects.

Abstract
Heterospecific autoantibodies to axonal neurofilaments of neurons in sera from five patients with Creutzfeldt-Jakob disease were detected with the use of cryostat section from normal human brain caudate nucleus. The antibody, visualized by the indirect immunofluorescence technique, was shown to bind complement. This allowed to achieve brighter staining either by the anticomplementary method alone or by a combination of both anti-C3 and anti-IgG conjugates

Abstract
The serums of some patients with subacute spongiform encephalopathies contain an autoantibody in higher titer against a normal fibrillar protein within the axon of mature central neurons in culture. The morphological features of this neurofilament, as demonstrated by immunofluorescence and immunoperoxidase staining, and the partial characterization of the antibody are described. The detection of this hetero-specific autoantibody is the first evidence of an immune reaction in the spongiform encephalopathies.

Abstract
Histocompatibility antigens were defined in 25 members of a Finnish family in which Creutzfeldt-Jakob disease (CJD) was diagnosed clinically in 4 cases and neuropathologically in 3 cases; 3 further cases had a history of presenile dementia. 2 HLA haplotypes were defined in 3 patients and deduced in a further 3 cases; only one haplotype could be deduced in 2 patients. CJD was not linked with a single haplotype, but at least 7 out of 8 patients with this disease apparently shared the HLA antigens A28 and B8.

Abstract
The pathogenesis of the slow virus encephalopathies and multiple sclerosis is reviewed within the framework of the immune response. The diseases are analyzed for the component of the immune response that appears to be crucial to the host's failure to control the disease. Thus, the absence of an immune response in the spongiform encephalopathies appears to reflect a failure of antigen recognition. Progressive multifocal leukoencephalopathy (PML), subacute sclerosing panencephalitis (SSPE), and progressive rubella panencephalitis (PRP) may result principally from a failure of effector mechanisms. In PML the failure usually occurs within the setting of an immunosuppressive illness. Conversely, in SSPE and PRP the effector failure seems to result from the nature of the host-virus interaction itself. Finally, evidence is accumulating that a defect of immunoregulation plays a significant role in multiple sclerosis.

Abstract
We determined the concentrations of IgA, IgG, and C3 in spinal fluid and IgA, IgG, IgM, and C3 in serum from seven patients with histologically revified Creutzfeldt-Jakob disease. The mean total protein content in spinal fluid was significantly higher than in controls. The increased mean concentrations of IgA, IgG, and C3 in spinal fluid, and their respective mean percentages in spinal fluid, suggest a passage of IgG and C3 from blood into spinal fluid, and a possible production of IgA within the central nervous system.

Abstract
Cell strains were established in culture from fragments of the brain from 2 cases each of Jakob-Creutzfeldt (JC) disease and subacute sclerosing panencephalitis (SSPE). After about 12 weeks strains from the former spontaneously formed persistent heaped up nodules of cells which appeared to produce reticulin-like fibrils as well as confluent sheets of rounded and spindle, fibroblast-like cells. Similar sheets of cells were obtained from the cases of SSPE but the only nodules formed were smaller and ephemeral. Attempts to detect virus in all 4 strains were made by inoculation of supernatant fluids into cultures of other laboratory cells, haemadsorption, co-cultivation, electron microscopy and immunofluorescence, and testing for interferon production. No evidence was found by any of these methods of the persistent presence of virus in the strains. Immunofluorescence revealed a probable anti-glial cell IgM autoantibody in one case of JC disease. Morphologically some cells resembled astrocytes and others fibroblasts. Those from JC disease contained more vacuoles and redundant membranes than did those from the cases of SSPE, features that are particularly striking in brain cells in human and animal cases of the spongiform encephalopathies.

Abstract
Following intramuscular injection of Kuru and Jakob-Creutzfeldt brain material into chimpanzees, circulating lymphocytes became sensitized to scrapie mouse brain (and spleen) to a greater degree than to normal tissue. This sensitization subsided after about a month, to be followed some 90 days later by a secondary peak attributed to establishment of changes in the nervous system. Special sensitization to scrapie material occurs in Kuru and Jakob-Creutzfeldt disease, but is not specific to them. The immunological evidence suggests that parenchymatous destruction may precede astroglial hypertrophy in these diseases. An early peak occurred in animals inoculated with multiple sclerosis brain and normal brain, but neither showed a delayed second peak. Thus there was no evidence of establishment of infection, even though all four animals were in intimate contact for over 200 days, and no evidence of the injection of MS material itself having established an infection. Biohazards in Kuru, Jakob-Creutzfeldt and MS work appear to be very low. The significance of the increased sensitilization to scrapie material in Kuru and Jakob-Creutzfeldt disease, especially in relation to normal ageing (where it also increases), is discussed.

Abstract
The state of the immune system, both humoral and cell-mediated, was evaluated in motor neurone disease (MND) patients. The data obtained for the MND patients were confronted with normal controls and a group of patients affected by nervous diseases not involving the immune system. Some differences were observed between MND patients and normal subjects, namely: increase of WBC and gamma-globulin in MND patients. However, such differences were not observed between MND patients and pathological controls, and therefore are probably due to a higher frequency of infectious complications in MND patients in respect to normal controls. The capacity of the immune system to respond to an adequate stimulus was normal, and no precipitating anti-CNS antibodies were detected in MND sera. Furthermore, no sex-linked differences were observed and the CSF abnormalities observed in 2 out of 16 MND patients were probably reflecting only destruction of CNS cells. The data are discussed in view of the possible pathogenetic mechanisms of MND.
