Sialoadhesin and CD163 join forces during entry of the porcine reproductive and respiratory syndrome virus.
The porcine reproductive and respiratory syndrome virus (PRRSV) shows a restricted tropism for subsets of porcine macrophages in vivo. To date, two PRRSV receptors have been identified on primary macrophages, heparan sulphate for binding and sialoadhesin for binding and internalization. However, additional factors are needed because the expression of both receptors in non-permissive cells resul...
متن کاملDirected Blocking of TGF-β Receptor I Binding Site Using Tailored Peptide Segments to Inhibit its Signaling Pathway
Background: TGF-β isoforms play crucial roles in diverse cellular processes. Therefore, targeting and inhibiting TGF-β signaling pathway provides a potential therapeutic opportunity. TGF-β isoforms bind and bring the receptors (TβRII and TβRI) together to form a signaling complex in an ordered manner. Objectives: Herein, an antagonistic variant of TGF-β (AnTβ)...
متن کاملFunction of CD163 fragments in porcine reproductive and respiratory syndrome virus infection.
Monocyte/macrophage scavenger receptor CD163 plays an important role in porcine reproductive and respiratory syndrome virus (PRRSV) infection. To identify the domains of CD163 involved in PRRSV infection, CD163 fragments P1 (1-798 bp), P2 (790-2046 bp), P3 (2023-3345 bp), Y-P1 (160-798 bp), Y-P2 (790-2046 bp) and Y-P3 (2143-3084 bp) were expressed by eukaryotic and prokaryotic expression system...
متن کاملProtection against porcine reproductive and respiratory syndrome virus (PRRSV) infection through passive transfer of PRRSV-neutralizing antibodies is dose dependent.
Previous work in our laboratory demonstrated that passive transfer of porcine reproductive and respiratory syndrome virus (PRRSV)-neutralizing antibodies (NA) protected pregnant sows against reproductive failure and conferred sterilizing immunity in sows and offspring. We report here on the dose requirement for protection by passive transfer with NA in young weaned pigs. The presence of a 1:8 t...
متن کاملDrug Trafficking into Macrophages via the Endocytotic Receptor CD163
In inflammatory diseases, macrophages are a main producer of a range of cytokines regulating the inflammatory state. This also includes inflammation induced by tumor growth, which recruits so-called tumor-associated macrophages supporting tumor growth. Macrophages are therefore relevant targets for cytotoxic or phenotype-modulating drugs in the treatment of inflammatory and cancerous diseases. ...
