SIGNED:~~ 4 ACKNOWLEDGEMENTS I would like to first acknowledge my parents Jim and Linda Vanderah for their support throughout my college education and for teaching me how to be responsible in accomplishing my goals. I am grateful to my grandfather, Roger O'Toole, who has continually enlightened me and stimulated my desire to learn more about the world around us. I would also like to thank my brother, Tony and my sisters Kari and Nicole for encouraging me to continue my education. I would like to especially acknowledge Dr. Frank Porreca for his guidance and support. Dr. Porreca has been nothing less than a father to me, setting an example of what I can only hope to achieve in the future. His brilliance in science and teaching is something I will cherish throughout my career. I would like to extend my appreciation to both Dr. Porreca and his wife, Gabriella, who have been extremely kind and generous to me and my family. I would like·to thank Dr. Yamamura for his leadership and assistance in the field of molecular pharmacology, as well as for helping me receive my first National Institute of Health fellowship. Dr. Yamamura has given me continual and strong encouragement in my school and experimental studies. A sincere thanks is in order for my other committee members, including Dr. Roeske, Dr. Laird and Dr. Lai, for their input and assistance in helping me achieve my doctorate degree. Lastly, I would like to thank numerous friends and family for helping me in my studies, experiments and for support. First, I would like to thank Drs. Robert Horvath, Ken Wild, Antonia Mattia, Qi Jiang, as well as Pam Peterson, Kent Menkens, Rob Bernstein and Ed Bilsky for their help in my experiments for this dissertation. I would also like to thank several other friends that have helped make life during graduate school bearable including, Nick Perrotta, Mike Nichols, Carl Kovelowski, Wanda Hauglum, Russ Ingersoll, Steve Stratton, Tom Ziegler, Mike Ossipov, John McCormick, Chuck Bian, Kathy Dillon, Kim Mayfield, Tracy Crook, Peg Davis, Rebecca Craft, John Murphy, Roland Cooper, Pierre-Louis LIeu, Sue Maxwell, Kathy Lee, Vanna Santoro, Eva Varga, Ichiro Sora, Richard Knapp, Ewa Malatynska, Jeremy Richman, Irene De Leon, Elizabeth Babin, Terri Vorholzer, Anita Russell, Rita Wedell, Jane Ageton, Karla Hayes and Sandy Sledge. I would also like to thank the support relatives gave me including Dr. John Jansheski and his wife Andree, Gloria Felice, Randy Gingerelli and Mark Jansheski. A very special thanks is in order for those who have helped in preparing and proof-reading this dissertation including Dr. Porreca, Sue Waite, Gina Jansheski, Mike Nichols, Ed Bilsky and Dr. Ossipov. 5 DEDICATION I would like to dedicate this dissertation to my wonderful wife, Gina Jansheski, and my beautiful children, Jordan, Jared and Ryan. My wife and children have continually supported and encouraged me throughout my college career. Although there have been times were I have been extremely busy at work, my wife and family understood and never discouraged me from completing my degree. Over the past four years my family has done more for me than I can ask for in a lifetime. Therefore, it is only proper that I dedicate this dissertation to them. 6 TABLE OF CONTENTS Page LIST OF ILLUSTRATIONS ................................. 9 LIST OF TABLE ............•.......................... 16 ABSTRACT ..........•..•............................ 17 INTRODUCTION . • . • . • . 19 Background ...•....•.....•...................... 1 9 Nociception and Pain Pathways ........•........•. 20 Opiates .................................... 25 Pain and the Medicinal Use of Opiates . 26 Opioid Receptors and Endogenous Opioids . .. 28 Endogenous Opioids and Stress . 36 Cloning and Molecular Mechanisms of Opioid Receptors .. 38 Delta Opioid Receptors and Their Relationship to Pain .... 53 Evidence for Opioid Delta Receptor Subtypes . .. 60 Modulatory Effects on Mu Agonists . 67 Hypothesis of the Dissertation . 71 METHODS ........................................... 75 Animals ........................................ 75 Chemicals ....................................... 75 Antisera ........................................ 76 Injection Techniques ............................... 77 Intracerebroventricular Injections . 77 Spinal Injections . • • . 77 Subcutaneous and Intraperitoneal Injections . .. 77 7 Intraplantar Injections .......................... 78 Tail-Flick Assay . 78 Evaluation of Hyperalgesia ........................... 79 Cold-Water Swim-Stress ............................. 80 Cold-Water Swim-Stress Modulation .................... 80 Experimental Procedures ............................. 81 Agonist/Antagonist Studies ...................... 81 Administration of Oligodeoxynucleotides . .. 85 Tolerance and Cross-Tolerance Studies . 87 Body Temperature . 89 Statistics ....................................... 90 Cloning of an Orphan Receptor ........................ 90 Expression and Characterization of the Orphan Receptor . .. 93 Delta Receptor Subtype Studies Results ......................................... 95 Summary ...................................... 101 Cold-Water Swim-Stress Studies Results . 1 06 Summary ...................................... 1 33 Cold-Water Swim-Stress Modulation Studies Results . 141 Summary ... .. 1 50 8 Delta Receptor Modulation Studies in
