Abstract: Methods and compositions are provided for at least slowing the progression of a filovirus mediated disease condition in a host. In the subject methods, an effective amount of an agent that at least reduces the amount of folate receptor mediated filovirus cell entry is administered to the host. The subject methods find use in both the prevention and treatment of filovirus associated disease conditions, including Marburg and Ebola-Zaire virus mediated disease conditions.

Abstract: The invention provided herein describes ligands and methods for modulating a G protein-coupled receptor (GPCR), designated G2A, a lymphocyte expressed receptor whose genetic ablation results in the development of autoimmunity. The present disclosure teaches that lysophosphatidylcholine (LPC) is a high affinity ligand for G2A and that sphingosylphosphorylcholine (SPC) is a lower affinity ligand for G2A. As G2A activation is shown to be involved in a variety of physiological processes including cell proliferation, autoimmunity and inflammation, methods which modulate its activity have a variety of diagnostic and therapeutic applications.

Abstract: A protein designated TRAIL receptor binds the protein known as TNF-Related Apoptosis-Inducing Ligand (TRAIL). The TRAIL receptor finds use in purifying TRAIL or inhibiting activities thereof. Isolated DNA sequences encoding TRAIL-R polypeptides are provided, along with expression vectors containing the DNA sequences, and host cells transformed with such recombinant expression vectors. Antibodies that are immunoreactive with TRAIL-R are also provided.
