We observed the changes in the central nervous system (CNS) of transgenic mice expressing bovine prion protein (Bo-PrP) as a contribution to our knowledge of the pathogenesis of bovine spongiform encephalopathy (BSE). The main result was the detection of hyperphosphorylated tau. This protein was detected for the first time, using immunohistochemical(More)
Pre-emptive culling is becoming increasingly questioned as a means of controlling animal diseases, including classical swine fever (CSF). This has prompted discussions on the use of emergency vaccination to control future CSF outbreaks in domestic pigs. Despite a long history of safe use in endemic areas, there is a paucity of data on aspects important to(More)
In humans, insert mutations within the repetitive octapeptide region of the prion protein gene (Prnp) are often associated with familial spongiform encephalopathies. In this study, transgenic mice expressing bovine PrP (boTg mice) bearing an additional octapeptide insertion to the wild type (seven octapeptide repeats instead of six) showed an altered course(More)
Transmissible spongiform encephalopathies (TSEs) can be ameliorated by prion protein (PrP)-specific antibodies, but active immunization is complicated by immune tolerance to the normal cellular host protein (PrP(C)). Here, we show that DNA immunization of wild-type mice can break immune tolerance against the prion protein, resulting in the induction of(More)
The leishmaniases are a complex of vector-borne diseases caused by protozoan parasites of the genus Leishmania. LEISHDNAVAX is a multi-antigen, T-cell epitope-enriched DNA vaccine candidate against human leishmaniasis. The vaccine candidate has been proven immunogenic and showed prophylactic efficacy in preclinical studies. Here, we describe the safety(More)
In transmissible spongiform encephalopathies (TSEs) the prion protein (PrP) plays a central role in pathogenesis. The PrP gene (Prnp) has been described in a number of mammalian and avian species and its expression product, the cellular prion protein (PrP(C)), has been mapped in brains of different laboratory animals (rodent and non-human primates).(More)
Influenza virus infection in pigs is a major farming problem, causing considerable economic loss and posing a zoonotic threat. In addition the pig is an excellent model for understanding immunity to influenza viruses as this is a natural host pathogen system. Experimentally, influenza virus is delivered to pigs intra-nasally, by intra-tracheal instillation(More)
The incidence of bovine tuberculosis (bTB) in the GB has been increasing since the 1980s. Immunisation, alongside current control measures, has been proposed as a sustainable measure to control bTB. Immunisation with Mycobacterium bovis bacillus Calmette-Guerin (BCG) has been shown to protect against bTB. Furthermore, much experimental data indicates that(More)
Porcine respiratory disease complex (PRDC) is a multifactorial respiratory syndrome related to the infection with different pathogens. Although most of these pathogens have been detected in the wild boar, the PRDC pneumonic lesions in this species have not been characterized. The aims of this study were to assess the presence of the main swine respiratory(More)
Monokines are glycoproteins, synthesised by macrophages, which exert various effects on the organism. The most important monokines are interleukin (IL)-1alpha, IL-1beta, tumor necrosis factor (TNF)-alpha and IL-6. This paper reports on immunohistochemical techniques developed for the detection of IL-alpha, IL-1beta, IL-6 and TNF-alpha in fixed and(More)
