A decoy receptor is a receptor that is able to recognize and bind specific growth factors or cytokines efficiently, but is not structurally able to signal or activate the intended receptor complex. It acts as an inhibitor, binding a ligand and keeping it from binding to its regular receptor. Decoy receptors participate in a common methods of signal inhibition and are also abundant in malignant tissues, making up a significant topic in cancer research.
A nanodecoy receptor that blocks the IL-17 signaling pathway, its preparation method and application

This invention discloses a nanodecoy receptor that blocks the IL-17 signaling pathway, including IL-17RA-CMVs carrying a fusion sequence of PDGFR-TMD and IL-17RA. This invention also provides a method for preparing the aforementioned nanodecoy receptor that blocks the IL-17 signaling pathway, comprising the following steps: S1. Using genetic engineering, IL-17RA and PDGFR-TMD are fused and designed, and a lentivirus carrying the IL-17RA and PDGFR-TMD fusion sequence is coated onto mammalian cells. A cell line stably expressing the IL-17RA and PDGFR-TMD fusion sequence is established in mammalian cells through lentivirus transfection; S2. The cell line from step S1 is taken, and cell membrane vesicles are prepared by ultrasonic disruption and permeabilization extrusion until the fusion sequence of IL-17RA carrying PDGFR-TMD is displayed at high density and correctly oriented on the outer surface of the cell membrane vesicles, forming IL-17RA-CMVs. The nano-decoy receptor of the present invention can efficiently and broadly block the interaction between IL-17 and IL-17RA, avoid such systemic side effects, and achieve treatment only through local minimally invasive delivery, thus solving the side effects problem caused by existing systemic drug administration.

Soluble recombinant human podoplanin receptor
This article discloses a material composition and a method for using the composition to treat... For example Methods for treating cancer or inflammatory joint diseases. The composition is a soluble recombinant human flatfoot protein receptor (srhPDPN) comprising a first amino acid sequence at least 95% homologous to SEQ ID NO:1. The srhPDPN may comprise a tag peptide or polypeptide (such as a multihistidine tag) fused to the first amino acid sequence. The srhPDPN may comprise a signal peptide fused to the first amino acid sequence. The signal peptide may comprise an amino acid sequence at least 95% homologous to SEQ ID NO:2. Multiple threonine residues of the srhPDPN may be partially glycosylated with sialic acid, and in some embodiments, 17 threonine residues of the srhPDPN are partially glycosylated with sialic acid. Treatment may include allowing the composition to act as a decoy receptor or ligand trap to inhibit PDPN signaling.
