The present invention relates to a novel antibody against HERV-K envelope that targets a conserved region not affected by glycosylation or by native conformation, and its use in diagnostics and/or is therapy.

The present invention features anti-HERV-K monoclonal antibodies or antigen-binding portions thereof. The present invention also features uses of the antibodies for treating HIV infection or HIV-associated conditions or diseases.

Nucleic acid-guided nuclease editing in mammalian cells may include passaging mammalian cells, in an automated closed cell editing instrument, into smaller aggregates when the aggregates exceed 50-300 microns in size. A library of viral particles may be delivered to the mammalian cells at a multiplicity of infection such that each mammalian cell receives one or no viral particle. The library may include viral vectors with an editing cassette including a pair of gRNA coding sequence and donor DNA. Conditions may be provided to allow a viral vector of the viral vectors to integrate into the mammalian cells. Enriching for mammalian cells may be done with an integrated viral vector. A nucleic acid-guided nuclease or nuclease fusion or a coding sequence for a nucleic acid-guided nuclease or nuclease fusion may be delivered to the enriched mammalian cells and conditions may be provided to allow editing in the mammalian cells.

The invention relates to an antibody, a fragment or a derivative thereof, for use as an antiretroviral drug targeting a virus belonging to human endogenous retroviruses type W (HERV-W), wherein said antibody, fragment or derivative thereof is directed against HERV-W Envelope protein (HERV-W Env). The invention also relates to a composition comprising said antibody and a retroviral reverse-transcriptase inhibitory drug, for use as an antiretroviral drug targeting a virus belonging to HERV-W.
