This syndrome occurs during numerous chronic diseases, such as cancer, cirrhosis, congestive heart failure, and rheumatoid arthritis. While mechanisms of cachexia are still not well understood, our lab and others demonstrated that inflammation within distinct brain regions can cause signs and symptoms similar to those observed during cachexia. Specifically, inflammation in the mediobasal hypothalamus can drive aberrant activation of the weight- and activity-mediating neurons in the region, causing decreased food intake, loss of skeletal muscle, and decreased locomotor activity. Mechanisms by which inflammation generated in the periphery is translated to inflammation in the brain have yet to be elucidated. Furthermore, cellular sources of neuroinflammation during cachexia are not known. The purpose of this dissertation was to identify and characterize the role of immune cells in the brain during cancer cachexia. 000007484 542__ $$fIn copyright - single owner 000007484 650__ $$aCachexia$$015945 000007484 650__ $$aMicroglia$$030120 000007484 650__ $$aNeutrophils$$022885 000007484 650__ $$aPancreatic Neoplasms$$023517 000007484 650__ $$aBrain$$015788 000007484 6531_ $$aneuroimmunology 000007484 691__ $$aSchool of Medicine$$041369 000007484 692__ $$aVollum Institute$$041509 000007484 7001_ $$aBurfeind, Kevin 000007484 8564_ $$9d5d3b183-34e6-4378-a458-654c55a28838$$s109844421$$uhttps://digitalcollections.ohsu.edu/record/7484/files/burfeind.kevin.2019.pdf 000007484 905__ $$a/rest/prod/69/69/z1/30/6969z130f 000007484 909CO $$ooai:digitalcollections.ohsu.edu:7484$$pstudent-work 000007484 980__ $$aTheses and Dissertations
