Placental syncytins: Genetic disjunction between the fusogenic and immunosuppressive activity of retroviral envelope proteins

…, O Heidmann, C Letzelter, A Richaud… - Proceedings of the …, 2007 - National Acad Sciences
We have previously demonstrated that the envelope proteins of a murine and primate
retrovirus are immunosuppressive in vivo. This property was manifested by the ability of the …

Identification of an infectious progenitor for the multiple-copy HERV-K human endogenous retroelements

M Dewannieux, F Harper, A Richaud… - Genome …, 2006 - genome.cshlp.org
Human Endogenous Retroviruses are expected to be the remnants of ancestral infections of
primates by active retroviruses that have thereafter been transmitted in a Mendelian fashion. …

Comparative genomics of 10 new Caenorhabditis species

…, K Kiontke, MD Newton, LM Noble, A Richaud… - Evolution …, 2019 - academic.oup.com
The nematode Caenorhabditis elegans has been central to the understanding of metazoan

The Local Coexistence Pattern of Selfing Genotypes in Caenorhabditis elegans Natural Metapopulations

A Richaud, G Zhang, D Lee, J Lee, MA Félix - Genetics, 2018 - academic.oup.com
To study the interplay of rare outcrossing and metapopulation structure, we focus on the
nematode Caenorhabditis elegans. Its remarkably low outcrossing rate is at the extreme end of …

Genome‐wide association and environmental suppression of the mortal germline phenotype of wild C. elegans

L Frézal, M Saglio, G Zhang, L Noble, A Richaud… - EMBO …, 2023 - embopress.org
The animal germline lineage needs to be maintained along generations. However, some
Caenorhabditis elegans wild isolates display a mortal germline phenotype, leading to sterility …

MA Félix, M Ailion, JC Hsu, A Richaud, J Wang - PloS one, 2018 - journals.plos.org
The lifestyle and feeding habits of nematodes are highly diverse. Several species of Pristionchus
(Nematoda: Diplogastridae), including Pristionchus pacificus, have been reported to be …

Vertical transmission in Caenorhabditis nematodes of RNA molecules encoding a viral RNA-dependent RNA polymerase

A Richaud, L Frézal, S Tahan, H Jiang… - Proceedings of the …, 2019 - National Acad Sciences
Here, we report on the discovery in Caenorhabditis nematodes of multiple vertically transmitted
RNAs coding for putative RNA-dependent RNA polymerases. Their sequences share …

The SOS screen in Arabidopsis: a search for functions involved in DNA metabolism

The SOS screen, as originally described by Perkins et al. (1999) [7], was setup with the aim
of identifying Arabidopsis functions that might potentially be involved in the DNA metabolism. …

Natural variation in infection specificity of Caenorhabditis briggsae isolates by two RNA viruses

C Alkan, G Bresard, L Frezal, A Richaud, A Ruaud… - bioRxiv, 2024 - biorxiv.org
Antagonistic relationships such as host-virus interactions potentially lead to rapid evolution
and specificity in interactions. The Orsay virus is so far the only horizontal virus naturally …
