Unexpected high frequency of neurofibroma in the celiac ganglion of German cattle.

In a study originally designed to find potential risk factors for bovine spongiform encephalopathy (BSE) we examined tissues from 403 Holstein Frisian cattle in total. These included 20 BSE cattle and their 236 birth- and feeding cohort animals plus 32 offspring, 103 age, breed and district-matched control cattle and further twelve cattle with neurological signs. In addition to the obex, we examined the celiac ganglion, cervical cranial ganglion, trigeminal ganglion and proximal ganglion of the vagus nerve using histological techniques.

Foodborne transmission of bovine spongiform encephalopathy to nonhuman primates.

Risk for human exposure to bovine spongiform encephalopathy (BSE)-inducing agent was estimated in a nonhuman primate model. To determine attack rates, incubation times, and molecular signatures, we orally exposed 18 macaques to 1 high dose of brain material from cattle with BSE. Several macaques were euthanized at regular intervals starting at 1 year postinoculation, and others were observed until clinical signs developed.

Similarities between forms of sheep scrapie and Creutzfeldt-Jakob disease are encoded by distinct prion types.

Transmissible spongiform encephalopathies such as scrapie in sheep, Creutzfeldt-Jakob disease (CJD) in humans, and bovine sporadic encephalopathy in cattle are characterized by the accumulation of a misfolded protein: the pathological prion protein. Ever since bovine sporadic encephalopathy was discovered as the likely cause of the new variant of CJD in humans, parallels between human and animal transmissible spongiform encephalopathies must be viewed under the aspect of a disease risk for humans. In our study we have compared prion characteristics of different forms of sheep scrapie with those of different phenotypes of sporadic CJD.

Increase in CD230 (cellular prion protein) fluorescence on blood lymphocytes in bovine spongiform encephalopathy-infected nonhuman primates.

Background: The cellular prion protein (PrP(c)) plays a central role in prion diseases such as variant Creutzfeldt-Jakob disease. This disease can be transmitted by blood transfusion. However, the exact kinetics of blood infectivity and the blood fraction carrying infectivity have not yet been identified.

Time-course studies of 14-3-3 protein isoforms in cerebrospinal fluid and brain of primates after oral or intracerebral infection with bovine spongiform encephalopathy agent.

Experimental transmission of bovine spongiform encephalopathy (BSE) to cynomolgus monkeys (Macaca fascicularis) is an animal model for variant Creutzfeldt-Jakob disease (vCJD). The presence of 14-3-3 proteins in cerebrospinal fluid (CSF) samples indicates neuronal destruction and is therefore used as a clinical biomarker. However, time-course studies using 14-3-3 proteins have not been performed until now in simian vCJD.
