Sensitive detection systems for infectious agents in xenotransplantation*
Abstract Xenotransplantation of pig cells, tissues, or organs may be associated with transmission of porcine microorganisms, first of all of viruses, to the transplant recipient, potentially inducing a disease (zoonosis). I would like to define detection systems as the complex of sample generation, sample preparation, sample origin, time of sampling ...

Examining the potential for porcine-derived islet cells to harbour viral pathogens [PDF]
With an onus on safety in the potential use of porcine islet cells as a treatment for diabetes, the use of animals lacking exogenous pathogens is clearly important and multilevel screening strategies have been presented on testing animals and the product.

The porcine virome and xenotransplantation
The composition of the porcine virome includes viruses that infect pig cells, ancient virus-derived elements including endogenous retroviruses inserted in the pig chromosomes, and bacteriophages that infect a broad array of bacteria that inhabit pigs ...

Inactivation and inducible oncogenic mutation of p53 in gene targeted pigs. [PDF]
Mutation of the tumor suppressor p53 plays a major role in human carcinogenesis. Here we describe gene-targeted porcine mesenchymal stem cells (MSCs) and live pigs carrying a latent TP53(R167H) mutant allele, orthologous to oncogenic human mutant TP53 ...

Quantitation of Porcine Cytomegalovirus in Pig Tissues by PCR [PDF]
ABSTRACT A quantitative-competitive PCR for the quantification of porcine cytomegalovirus (PCMV) was developed. The virus was detected in a variety of pig organs (including potential xenotransplant donations), with viral loads ranging from <10 to 97 genome copies/μg of DNA.

Neoplastic transformation of porcine mammary epithelial cells in vitro and tumor formation in vivo. [PDF]
BackgroundThe mammary glands of pigs share many functional and morphological similarities with the breasts of humans, raising the potential of their utility for research into the mechanisms underlying normal mammary function and breast carcinogenesis ...

Late phase inhibition of murine cytomegalovirus replication by synergistic action of interferon-gamma and tumour necrosis factor [PDF]
We have shown previously that the antiviral function of CD4+ T lymphocytes against murine cytomegalovirus (MCMV) is associated with the release of interferon- (IFN-).

Pre-transplant antibody screening and anti-CD154 costimulation blockade promote long-term xenograft survival in a pig-to-primate kidney transplant model [PDF]
Xenotransplantation has the potential to alleviate the organ shortage that prevents many patients with end-stage renal disease from enjoying the benefits of kidney transplantation.

Expression of viral CD45 ligand E3/49K on porcine cells reduces human anti-pig immune responses
Transgenic expression of protective molecules in porcine cells and tissues is a promising approach to prevent xenograft rejection. Viruses have developed various strategies to escape the host’s immune system. We generated porcine B cells (B cell line L23)

Pathogen burden, inflammation, proliferation and apoptosis in human in-stent restenosis - Tissue characteristics compared to primary atherosclerosis [PDF]
Pathogenic events leading to in-stent restenosis (ISR) are still incompletely understood. Among others, inflammation, immune reactions, deregulated cell death and growth have been suggested. Therefore, atherectomy probes from 21 patients with symptomatic
