Abstract
Endogenous retroviruses (ERVs) are remnants of ancient retroviral infections in vertebrate genomes and are inherited by offspring. ERVs can produce pathogenic viruses through gene mutations or recombination. ERVs in domestic cats (ERV-DCs) generate feline leukemia virus subgroup D (FeLV-D) through viral recombination. Herein, we characterized the locus ERV-DC8, on chromosome B1, as an infectious replication-competent provirus. ERV-DC8 infected several cell lines, including human cells. Transmission electron microscopy of ERV-DC8 identified the viral release as a Gammaretrovirus. ERV-DC8 was identified as the FeLV-D viral interference group, with feline copper transporter 1 as its viral receptor. Insertional polymorphism analysis showed high ERV-DC8 integration in domestic cats. This study highlights the role, pathogenicity, and evolutionary relationships between ERVs and their hosts.

Abstract
AbstractFeline leukaemia virus (FeLV) is a retrovirus that infects domestic and wild cats around the world. FeLV infection is associated with the development of neoplasms, bone marrow disorders and immunosuppression. Viral subgroups arise from mutations in the FeLV genome or from recombination of FeLV with ancestral endogenous retroviruses in the cat genome. The retroviral endogenisation process has allowed generation of a diversity of endogenous viruses, both functional and defective. These elements may be part of the normal functioning of the feline genome and may also interact with FeLV to form recombinant FeLV subgroups, enhance pathogenicity of viral subgroups, or inhibit and/or regulate other retroviral infections. Recombination of the env gene occurs most frequently and appears to be the most significant in terms of both the quantity and diversification of pathogenic effects in the viral population, as well as affecting cell tropism and types of disease that occur in infected cats. This review focuses on available information regarding genetic diversity, pathogenesis and diagnosis of FeLV as a result of the interaction between endogenous and exogenous viruses.
