The present invention relates to novel antagonists to a B1-bradykinin (B1-BK) receptor which have a good affinity and selectivity therefor, some of which being at least partially resistant to enzymatic degradation. The synthesis of the B1 receptors is induced during inflammation. Symptoms associated with inflammation (elevated hydrostatic pressure and plasma leakage or extravasation) have been observed in diabetic animal models (streptozotocin-induced diabetes (STZ)) as well as in spontaneously hypertensive rats (SHR). The present inventors confirm the presence of B1-BK receptors in these two models. B1-BK antagonists abolished the vasocontraction induced by B1-BK in SHR and STZ, and reduced the glycemia of diabetic animals to normal levels. The present B1-antagonists are useful for treating any condition wherein B1-receptor is expressed, particularly during inflammation, and more particularly wherein B1-receptor expression results in diabetic vasculopathy, other diabetic symptoms associated with an insulitis and a post-capillary resistance building as a consequence of the presence of a B1-receptor.

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%.
