Abstract: The present invention describes compositions for both diagnostic and therapeutic applications. In one embodiment, the present invention contemplates a method of identifying an active M. tuberculosis infection. In another embodiment, the present invention contemplates a method of monitoring a M. tuberculosis infection. In yet another embodiment, the present invention contemplates a method of monitoring a patient's response to treatment for an active M. tuberculosis infection. In a further embodiment, the present invention contemplates a method of monitoring a patient's response to treatment for an active M. tuberculosis infection.

Abstract: This invention relates to vaccine formulations comprising the Yersinia pestis YopE peptide antigen or subparts thereof. The invention also relates to methods of vaccinating subjects at risk of Yersinia pestis infection as well as assays for measuring immune response to plague vaccines.

Abstract: The present invention describes compositions for both diagnostic and therapeutic applications. In one embodiment, the present invention contemplates a vaccine formulation comprising an antigen and IL12R?1 isoform 2. In some embodiments, this invention relates to a method of quantifying the ratio of IL12R?1 transcript and a splice variant thereof in a sample, including but not limited to at the cDNA level. In other embodiments, this invention relates to a method of augmenting an immune response by administering, inhibiting and/or inducing IL12R?1 isoform 2.

Abstract: The present invention relates to methods for modulating the migratory activity of cells expressing CD38 for the treatment of disorders including, but not limited to, inflammation, ischemia, asthma, autoimmune disease, diabetes, arthritis, allergies, infection with pathogenic organisms, such as parasites, and transplant rejection. Such cells include, for example, neutrophils, lymphocytes, eosinophils, macrophages and dentritic cells. The invention further relates to drug screening assays designed to identify compounds that modulate the ADP-ribosyl cyclase activity of CD38 and the use of such. compounds in the treatment of disorders involving CD38 modulated cell migration. Additionally, the invention relates to the isolation and characterization of a CD38 homologue from the parasitic flatworm, Schistosoma mansoni.

The invention further relates to drug screening assays designed to identify compounds that modulate the ADP-ribosyl cyclase activity of CD38 and the use of such compounds in the treatment of disorders involving CD38 modulated cell migration. The invention is based on the discovery that CD38 ADP-ribosyl cyclase activity is required for chemotaxis. Furthermore, the invention relates to methods for identifying compounds that modulate the enzyme activity of the S. mansoni CD38 homologue and using those compounds in the treatment of pathologic disorders caused by helminth infection.
