Generation of neutralising antibodies against porcine endogenous retroviruses (PERVs) [PDF]

open access: yesVirology, 2011
Antibodies neutralising porcine endogenous retroviruses (PERVs) were induced in different animal species by immunisation with the transmembrane envelope protein p15E. These antibodies recognised epitopes, designated E1, in the fusion peptide proximal region (FPPR) of p15E, and E2 in the membrane proximal external region (MPER).

The origin of porcine endogenous retroviruses (PERVs)

Archives of Virology, 2021
Porcine endogenous retroviruses (PERVs) are integrated in the genome of all pigs, and they produce viral particles that are able to infect human cells and therefore pose a special risk for xenotransplantation. In contrast to other pig microorganisms that also pose a risk, such as porcine cytomegalovirus and hepatitis E virus, PERVs cannot be eliminated

Genome-wide inactivation of porcine endogenous retroviruses (PERVs) [PDF]

open access: yesScience, 2015
Virally cleansing the pig genome Transplants from pigs could be a solution to a shortage of human organs for transplantation. Unfortunately, porcine endogenous retroviruses (PERVs) are rife in pigs and can be transmitted to humans, risking disease. L. Yang et al.

Unexpected low expression of porcine endogenous retroviruses (PERVs) in porcine expanded potential stem cells (EPSCs)

open access: yesVirus Research, 2021
Expanded potential stem cells (EPSCs) have been recently derived from porcine preimplantation embryos (Gao et al., 2019). These cells were shown to express key pluripotency genes, to be genetically stable and differentiate to derivatives of the three germ layers and additionally to trophoblast.

Modulation of Porcine Endogenous Retroviruses (PERVs) expression in vitro by shRNA in the presence of cyclosporine A and dexamethasone

open access: yesAnnals of Transplantation, 2012
Despite the fact that the risk of Porcine Endogenous Retroviruses (PERV) infection and propagation in human recipients is extremely low, such an event cannot be completely ruled out, especially in immunosuppressed patients. Therefore, the aim of this study was to analyze the expression of PERVs in vitro in the presence of immunosuppression agents ...

Expression of porcine endogenous retroviruses (PERVs) in melanomas of Munich miniature swine (MMS) Troll

open access: yesVeterinary Microbiology, 2007
Porcine endogenous retroviruses (PERVs) are integrated in the genome of all pig breeds. Since some of them are able to infect human cells, they might represent a risk for xenotransplantation using pig cells or organs. However, the expression and biological role of PERVs in healthy pigs as well as in porcine tumours is largely unknown.
