Microchimerism, PERV and Xenotransplantation
Viruses, 2023 Microchimerism is the presence of cells in an individual that have originated from a genetically distinct individual. The most common form of microchimerism is fetomaternal microchimerism, i.e., cells from a fetus pass through the placenta and establish ...

How Active Are Porcine Endogenous Retroviruses (PERVs)? [PDF]
Viruses, 2016 Porcine endogenous retroviruses (PERVs) represent a risk factor if porcine cells, tissues, or organs were to be transplanted into human recipients to alleviate the shortage of human transplants; a procedure called xenotransplantation.

The restriction of zoonotic PERV transmission by human APOBEC3G. [PDF]
PLoS ONE, 2007 The human APOBEC3G protein is an innate anti-viral factor that can dominantly inhibit the replication of some endogenous and exogenous retroviruses. The prospects of purposefully harnessing such an anti-viral defense are under investigation.

Transmission of Porcine Endogenous Retrovirus Produced from Different Recipient Cells In Vivo. [PDF]
PLoS ONE, 2016 Humanized pigs have been developed to reduce the incidence of immune rejection in xenotransplantation, but significant concerns remain, such as transmission of viral zoonosis. Porcine endogenous retroviruses (PERV), which exist in the genome of pigs, are

Analysis of PERV-C superinfection resistance using HA-tagged viruses
Retrovirology, 2023 Background Using pigs as organ donors has advanced xenotransplantation to the point that it is almost ready for clinical use. However, there is still a zoonotic risk associated with xenotransplantation, and the potential transmission of porcine ...

Characterization of Insertional Variation of Porcine Endogenous Retroviruses in Six Different Pig Breeds [PDF]
Asian-Australasian Journal of Animal Sciences, 2012 Pigs may need to be exploited as xenotransplantation donors due to the shortage of human organs, tissues and cells. Porcine endogenous retroviruses (PERVs) are a significant obstacle to xenotransplantation because they can infect human cells in vitro and

Suboptimal porcine endogenous retrovirus infection in non-human primate cells: implication for preclinical xenotransplantation. [PDF]
PLoS ONE, 2010 BACKGROUND: Porcine endogenous retrovirus (PERV) poses a potential risk of zoonotic infection in xenotransplantation. Preclinical transplantation trials using non-human primates (NHP) as recipients of porcine xenografts present the opportunity to assess ...

Microorganisms, 2021 Minipigs play an important role in biomedical research and have also been used as donor animals in xenotransplantation. To serve as a donor in xenotransplantation, the animals must be free of potential zoonotic viruses, bacteria and parasites.

t-structures for relative D-modules and t-exactness of the de Rham functor [PDF]
, 2018 This paper is a contribution to the study of relative holonomic D-modules. Contrary to the absolute case, the standard t-structure on holonomic D-modules is not preserved by duality and hence the solution functor is no longer t-exact with respect to the

Virology Journal, 2022 Background Porcine endogenous retroviruses (PERVs) can infect human cells and pose a risk for xenotransplantation when pig cells, tissues or organs are transplanted to human recipients.
