Risk. Mild dengue fever presents with headache, fever, rash, myalgia, osteogenic pain, and lethargy. Severe disease can manifest as dengue shock syndrome (DSS) or dengue hemorrhagic fever (DHF). Symptoms of DSS/DHF are leukopenia, low blood volume and pressure encephalitis, cold and sweaty skin, gastrointestinal bleeding, and spontaneous bleeding from gums and nose. Currently, there are no therape

Neutralization. However, in heterotypic dengue virus infections the antibodies are non-neutralizing and lead to enhancement. Two cell lines expressing either FcRIA or FcRIIA have been used to demonstrate that immune complexes can enhance virus infectivity in an FcR mediated fashion. FcRIA is found exclusively on macrophages and dendritic cells and preferentially binds monomeric IgG, while FcRIIA i

At typically binds to IgG and is composed of an chain for domain recognition, an ITAM (immunoreceptor tyrosine based activation motif), and a chain that is responsible for signal transduction. It is thought that IgM does not play a direct role in ADE and instead contributes to disease pathogenesis through activation of complement receptors[13]. IgM antibody enhancement was abrogated when C3R is
