Altered Leptin Signaling On Dendritic Cells As A Potential Mechanism For Cancer Immunotherapy, Lorena Y. De Los Santos
Altered Leptin Signaling On Dendritic Cells As A Potential Mechanism For Cancer Immunotherapy, Lorena Y. De Los Santos
Open Access Theses & Dissertations
Leptin is a pleiotropic hormone synthesized primarily by white adipocytes and its receptors are expressed in a variety of tissues and cells such as in the hypothalamus and cells of the immune system. Multiple cell types can produce a considerable amount of leptin such as skeletal muscle, placenta, and osteoblasts to name a few and its synthesis has been shown to be regulated by sex hormones and a broad range of inflammatory mediators. Although leptin has been shown to directly affect immune response, we are interested in how leptin affects dendritic cell function and their ability to induce a proper …

Lysophosphatidic Acid Production And Signaling In Platelets, Zachary Bennett Fulkerson
Theses and Dissertations--Physiology
Lysophosphatidic acid (LPA) belongs to a class of extracellular lipid signaling molecules. In the vasculature, LPA may regulate platelet activation and modulate endothelial and smooth muscle cell function. LPA has therefore been proposed as a mediator of cardiovascular disease.
The bulk of circulating LPA is produced from plasma lysophosphatidylcholine (LPC) by autotaxin (ATX), a secreted lysophospholipase D (lysoPLD). Early studies suggest that some of the production of circulating LPA is platelet-dependent. ATX possesses an N-terminal somatomedin B-like domain suggesting the hypothesis that ATX interacts with platelet integrins which may localize ATX to substrate in the membrane and/or alter the catalytic …

INTRACELLULAR SIGNALING AND INTEGRATION ABNORMALITIES IN SCHIZOPHRENIA Adam J. Funk DEPARTMENT OF NEUROBIOLOGY ABSTRACT The pathophysiology of schizophrenia is complex and diverse, with many classes of receptors, neurotransmitters, and brain regions implicated in this illness. The many hypotheses proposed have yet to fully explain the heterogeneity of the genetic, postmor-tem, and clinical evidence. It is the goal of this dissertation to integrate the current hy-potheses of schizophrenia into a unified hypothesis of abnormal intracellular signaling and signal integration. Inconsistencies in genetic and postmortem findings suggest that the development of schizophrenia is multifaceted, and the heterogeneity of symptoms supports the hypothesis …
