We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Regulation of Immune Responses by Interleukin-23 @ University of North Texas Hlth Sci Ctr
[unreadable] DESCRIPTION (provided by applicant): Interleukin- 23 (IL-23), which belongs to the IL-12 family of cytokines, has previously been described as having either redundant functions with IL-12 or promoting the differentiation of a novel CD4 T cell subset that produces IL-17. However, our data is the first to indicate that IL-23 can also negatively regulate the secretion of IFN-gamma that is induced by IL-12. Furthermore, we have also shown that IL-23 is involved in promoting IL-17 secreting CD8T cells. Our results have led us to hypothesize that IL-23 plays a novel and important role in CD8 T cell immunity against pathogens by antagonizing IL-12 induced effector functions and promoting the secretion of IL-17. In specific Aim I, we will determine which CD8 T cell effector functions are regulated by IL-23 and whether or not IL-23 plays a role in regulating IFN-gamma production in response to infections. Specific Aim II will identify the mechanisms and signaling pathways involved in IL-23 mediated regulation of IL-12 induced effector functions. Finally, specific Aim III will determine the role of IL- 23 in promoting the secretion of IL-17 from CD8 T cells. The information gathered from these specific aims will increase our knowledge of how IL-23 can regulate early immune responses against pathogens, by decreasing IFN-gamma production and other CD8 T cell effector functions. These studies will also delineate how IL-23 can impact the generation of adaptive immune responses by promoting IL-17 secreting CD8 T cell responses. The results of the experiments outlined within this proposal will further our knowledge of the role of cytokines, particularly IL-23, in immune responses to infectious pathogens. Understanding immune responses to disease causing microbes will enable us to more efficiently control these diseases. [unreadable] [unreadable] [unreadable]
