    Abstract: Cellular receptors are identified that induce plasma leakage and other negative effects when infected with flaviviruses, such as dengue virus or Japanese encephamyelitis virus. Using fusion proteins disclosed herein, the receptors to which a pathogen, such as flavivirus, binds via glycan binding are determined. Once the receptors are determined, the effect of binding to a particular receptor may be determined, wherein targeting of the receptors causing a particular symptom may be targeted by agents that interrupt binding of the pathogen to the receptor. Accordingly, in the case of dengue virus and Japanese encephamyelitis virus, TNF-α is released when the pathogen binds to the DLVR1/CLEC5A receptor. Interrupting the DLVR1/CLEC5A receptor with monoclonal antibodies reduced TNF-α secretion without affecting secretion of cytokines responsible for viral clearance thereby increasing survival rates in infected mice from nil to around 50%.

    Abstract: The disclosure provides fusion proteins comprising a carbohydrate recognition domain of an innate immunity receptor and a heterologous polypeptide. The fusion proteins of the disclosure may be used, for example, to fingerprint polysaccharide compositions and to purify polysaccharide compositions. Polysaccharide compositions include those isolated from Ganoderma lucidum (Reishi). The methods and reagents of the disclosure may also be used to identify innate immunity receptors and cell types that bind to polysaccharide compositions (including polysaccharide compositions associated with pathogens), whereupon modulators of the identified receptors can then be obtained. The fusion proteins also may be used to inhibit the interaction between a polysaccharide composition and an innate immunity receptor on a cell surface. The methods and reagents of the disclosure are used in one example to determine that the DLVR1 innate immunity receptor on macrophages interacts with Dengue virus (DV), and that DLVR1 is responsible for DV-mediated secretion of proinflammatory cytokines from macrophages. The disclosure also provides DVLR1 antibodies that prevent the secretion of proinflammatory cytokines by DV-infected macrophages.
