Distinct effects of complement C4A and C4B copy number in Systemic Sclerosis serological and clinical subtypes

Arthritis &Rheumatology, Accepted Article.
Objective Complement component 4 (C4), encoded by C4A and C4B within the major histocompatibility complex (MHC) on chromosome 6, regulates the immune response and clears immune complexes. Variable copy number (CN) of C4 genes and retroviral HERV‐K element influence its function.

Automation of an integrated micro‐scale platform for monoclonal antibody process development by incorporation of a depth filter mimic

Biotechnology Progress, EarlyView.
Integrating non‐chromatographic operations, such as low pH viral inactivation and a depth filtration mimic, into an automated micro‐scale platform enhances productivity while reducing resource and time requirements. By facilitating rapid, data‐rich experimentation, the platform offers a powerful and efficient tool for assessing and optimizing ...

Sequences, annotation and single nucleotide polymorphism of the major histocompatibility complex in the domestic cat.

PLoS ONE, 2008
Two sequences of major histocompatibility complex (MHC) regions in the domestic cat, 2.976 and 0.362 Mbps, which were separated by an ancient chromosome break (55-80 MYA) and followed by a chromosomal inversion were annotated in detail.

Acquisition and Exaptation of Endogenous Retroviruses in Mammalian Placenta

Biomolecules, 2023
Endogenous retroviruses (ERVs) are retrovirus-like sequences that were previously integrated into the host genome. Although most ERVs are inactivated by mutations, deletions, or epigenetic regulation, some remain transcriptionally active and impact host ...

Inhibition of budding/release of porcine endogenous retrovirus [PDF]

Microbiology and Immunology, 2014
AbstractPERV is integrated into the genome of all pigs. PERV‐A and PERV‐B are polytropic and can productively infect human cell lines, whereas PERV‐C is ecotropic. Recombinant PERV‐A/C can infect human cells and exhibits high titer replication. Therefore, use of pigs for human xenotransplantation raises concerns about the risks of transfer of this ...

Performance of large virus removal filters during AAV processing: Influence of flux and process disruptions

Biotechnology Progress, EarlyView.
Abstract As adeno‐associated viral vectors (AAV) continue to advance through the clinical pipeline, effective downstream purification strategies must be developed to ensure bulk drug purity and safety. AAV are produced within mammalian cells, bringing forth risks associated with viral contamination.

Differential resistance to cell entry by porcine endogenous retrovirus subgroup A in rodent species [PDF]

, 2007
Background: The risk of zoonotic infection by porcine endogenous retroviruses (PERV) has been highlighted in the context of pig-to-human xenotransplantation. The use of receptors for cell entry often determines the host range of retroviruses.

A two‐sample Mendelian randomization study and mediation analysis exploring the link between cathepsins and epilepsy

Epilepsia Open, EarlyView.
Abstract Objective This study aims to investigate the causal relationship between cathepsins and epilepsy, using Mendelian randomization (MR) and mediation analysis. Methods Publicly accessible summary statistics on epilepsy were obtained from FinnGen and the International League Against Epilepsy Consortium.

Retrovirus insertion site analysis of LGL leukemia patient genomes

BMC Medical Genomics, 2019
Background Large granular lymphocyte (LGL) leukemia is an uncommon cancer characterized by sustained clonal proliferation of LGL cells. Antibodies reactive to retroviruses have been documented in the serum of patients with LGL leukemia.

Nsd2 Represses Endogenous Retrovirus MERVL in Embryonic Stem Cells

Stem Cells International, 2021
The facilitates chromatin transcription (FACT) complex is a histone H2A/H2B chaperone, which represses endogenous retroviruses (ERVs) and transcription of ERV-chimeric transcripts. It binds to both transcription start site and gene body region.
