Dynorphins are endogenous opioid peptides that have been implicated as initiators ofimmune and inflammatory response through upregulation ofinflammatory cytokine and chemokine production, as well having a role in glutamate-induced neuro-inflammation and neurotoxicity. Being extremely potent peptides, the physiologic concentrations of dynorphins are very low ranging from 0.16 pg/mL during the absence of a stimulus to 23.5 pg/mL when stimulated in disease condition. Previously published HPLC-mass spectrometry techniques have insufficient detection capabilities for quantification and detection ofdynorphins. As a result, immunoassay quantification has been the most utilized technique for analysis of dynorphins in physiologic samples. Although being sensitive, immunoassays have some …

Thrombomodulin (TM) is a transmembrane glycoprotein that is primarily expressed on the surface of endothelial cells, where it serves as a receptor of thrombin for protein C activation, which regulates coagulation and inflammation. Research has revealed that TM is also expressed in immune cells, including monocytes and macrophages, however, its function is unclear. In this dissertation study, the TM expression in THP-1 monocytes upon their differentiation to macrophages was profiled. Due to the beneficial roles of TM, the protein has caught the attention to be used as a therapeutic. A recombinant form of TM can be expressed that contains EGF-like …
