Sandweiss 3 ACKNOWLEDGEMENTS The following text would not exist without the support of many individuals. First, Dr. Todd Vanderah, who offered me a position in the lab as an undergraduate while I attempted to figure things out about life and my future. On the same track as every other premed, I joined the lab to help myself get into medical school-- and maybe learn a few things along the way. It didn’t take long while working in this lab before I switched gears and deeply considered a career as a Ph.D. The science was fascinating. The process of asking the right questions and knowing how to answer them was intriguing. Watching the critical thinking unfold in others was awe-inspiring. All the cool stuff in the lab had this nerd hooked: I was going to be a scientist. But the prospect of not seeing patients and having a direct influence in their care bothered me. This naïve undergrad pondered how one could combine two careers into one. Dr. Vanderah lent a great deal of effort and time to help me reach my goals, starting with acceptance into medical school via the MD/Ph.D. program. It was easy to see why every single student in medical school likes Dr. Vanderah. He is inviting. He loves to teach, and he loves seeing the “ah-ha!” moment. He is non-judgmental. And he knows the brain! I hope one day, in my future career as a physician- scientist, professor, and mentor, I can be half as well-respected as Dr. Vanderah. This text likewise would not exist if it weren’t for Dr. Tally Largent-Milnes. As an undergrad, I contacted her (then Tally) and asked if she could help me find a lab to join, since she was my sister’s college roommate and good friend (now 4 great family friend). She had me in the lab by the end of the week and told me about these great peptides she was characterizing to inhibit pain. I asked “what the heck is a peptide?” She has seen me grow into the medical student and Ph.D. student I have become, and I have seen her grow into the magnificent scientist and mentor she has become. Thank you Tally; I wouldn’t be in the extremely lucky position I’m in without you. The members of my committee, Dr. Naomi Rance, Dr. Raj Khanna, Dr. Ed French, and Dr. Victor Hruby, have been extraordinarily helpful along the way. They have all provided great wisdom, sometimes scientific, sometimes philosophical. I have realized how important BOTH are to the success of a Ph.D. and M.D. After all, it’s called a ‘Doctor of Philosophy’ for a reason. The M.D./Ph.D. program director, Dr. Kenneth Ramos, has been instrumental in my success as well. He has asked extremely pertinent question regarding my project, helped with my NIH grant application, and has done a superb job reinvigorating the program here at the University of Arizona. The following text describes one of four major projects I spent much of my time participating in during my Ph.D. The other three major projects I worked on relate to migraine, conducting a clinical pilot study, and traumatic brain injury. The migraine project has come a long way; it was my first project in the lab as an undergraduate working with the now Dr. David Skinner. In addition, the TBI project was a very relevant/exciting project that I knew I wanted to be a part of to gain additional experience in the neurosciences, learn new scientific techniques, 5 and begin the networking process with those on the other side: the physicians. Dr. Bellal Joseph and Dr. Kareem Ibraheem have helped in my development into a physician-scientist more than they probably know. The pilot clinical study is related to my thesis written here. It would have fit nicely into this manuscript, but just as clinical research has gone for decades, we haven’t been able to recruit enough patients just yet. This is a critical skill I have learned from Dr. Kai Schoenage in the Department of Anesthesiology; a necessary component of my training as a physician-scientist that I would not have otherwise received. Thank you to each of you. I would like to acknowledge all of the other students in the Vanderah lab, past and present, graduate, undergraduate, and medical students. Dr. Kat Hanlon, Dr. Alysia Ondoua, Dr. Ashley Simons, Dr. Lauren Slosky, Warren Wang, Shaness Grenald, Karissa Cottier and Hong Zhang, all who will make excellent scientists as they complete their degrees. Dr. Aswini Giri has been a great friend and colleague to have in the chemistry department. The first undergraduate to help me on my project was Martin Faridian. He is now finishing up pharmacy school and will make an outstanding pharmacist. Likewise, Jackie Hu and Saul Ortega are finishing up their pharmacy degrees and Josh Stark provided vital assistance. Dr. Alex Podolsky is on his way to becoming an excellent neurologist at the prestigious University of Michigan. Mary McIntosh has been the most helpful undergraduate student to grace a lab. Her tireless 6 work ethic and devotion to doing good for the world will make her an outstanding doctor one day. Of course I wouldn’t have gotten through this phase in my life without my family. My mom, dad, Rebecca, Joshy-poo (supplied the Fruigees), Howie, and the lovely Dr. Dana McKee have pushed me and supported me along the way. Fruigees will be a household name soon and Dana will make an awesome Ob/Gyn, delivering babies tirelessly for the next 4 years. 7 DEDICATION This manuscript is dedicated to my grandparents. My late grandmother Jan Hyman was one of the kindest people I ever knew. She has a lasting impression on me with her gratitude, selflessness, and warm personality. She cared so much about her grandchildren and the future they would have. She died in 2005 when I was sixteen. The last thing she said to me--while on high dose morphine-- was “your skin hasn’t cleared up yet!” It’s cleared up now grandma, I promise. My grandpa Ed couldn’t wait until I was 13 so he could take his first son/grandson to the shooting range to teach me how to aim and shoot a 0.22. I’ve had my sights on the target ever since. My dad’s dad died before I had the chance to meet him but I’m told I get many of my superficial traits including my left-handedness and musicality from him. That was very right of him. My Bubbe is a super-grandma. She has so many grandchildren and now great grandchildren I don’t know how she keeps up with all of it. She’s constantly calling her children, grandchildren, and greatgrandchildren to hear what’s up. She suffers from a painful hip, one of the things that drives me in this field.

Wheat gluten proteins were assessed for the 6 presence of opioid peptides on the basis of tyrosine and proline within their sequence. Eleven 7 peptides were identified and occurrence of predicted sequences or their structural motifs were 8 analysed using BIOPEP database and ranked using PeptideRanker. Based on higher peptide 9 ranking, three sequences YPG, YYPG and YIPP were selected for determination of opioid 10 activity by cAMP assay against µ and κ opioid receptors. Three peptides inhibited the 11 production of cAMP to varied degree with EC50 values of YPG, YYPG and YIPP were 5.3 12 mM, 1.5 mM and 2.9 mM for µ-opioid receptor, and 1.9 mM, 1.2 mM and 3.2 mM for κ- 13 opioid receptor, respectively.

Since its discovery as an uncharacterized transmembrane protein in human fibroblasts, TRPA1 has become one of the most intensively studied ion channels. Its function has been linked to regulation of heat and cold perception, mechanosensitivity, hearing, inflam- mation, pain, circadian rhythms, chemoreception, and other processes. Some of these proposed functions remain controversial, while others have gathered considerable experimental support. A truly polymodal ion channel, TRPA1 is activated by various stimuli, including electrophilic chemicals, oxygen, temperature, and mechanical force, yet the molecular mechanism of TRPA1 gating remains obscure. In this review, we discuss recent advances in the understanding of TRPA1 physiology, pharmacology, and molecular function.

  • Cannabinoid Receptor and Inflammation
    Cannabinoid Receptor and Inflammation Newman Osafo1, Oduro Yeboah1, Aaron Antwi1, and George Ainooson1 1Kwame Nkrumah University of Science and Technology September 11, 2020 Abstract The eventual discovery of endogenous cannabinoid receptors CB1 and CB2 and their endogenous ligands has generated interest with regards to finally understanding the endocannabinoid system. Its role in the normal physiology of the body and its implication in pathological states such as cardiovascular diseases, neoplasm, depression and pain have been subjects of scientific interest. In this review the authors focus on the endogenous cannabinoid pathway, the critical role of cannabinoid receptors in signaling and mediation of neurodegeneration and other inflammatory responses as well as its potential as a drug target in the amelioration of some inflammatory conditions. Though the exact role of the endocannabinoid system is not fully understood, the evidence found leans heavily towards a great potential in exploiting both its central and peripheral pathways in disease management. Cannabinoid therapy has already shown great promise in several preclinical and clinical trials. 1.0 Introduction Ethnopharmacological studies have shown the use of Cannabis sativa in traditional medicine for over a thousand years, with its widespread use promoted by its psychotropic effects (McCoy, 2016; Turcotte et al., 2016). The discovery of a receptor within human body, that is selectively activated by cannabinoids suggested the presence of at least one endogenous ligand for this receptor. This is confirmed by the discovery of two endogenously synthesized lipid mediators, 2-arachidonoyl-glycerol and arachidonoylethanolamide, which function as high-affinity ligands for a subfamily of cannabinoid receptors ubiquitously distributed in the central nervous system, known as the CB1 receptors (Turcotte et al., 2016).

Since the use of opioids has escalated in recent years, it is increasingly important to understand biological mechanisms that can increase the probability of opioid-associated adverse events occurring in patient populations. This is emphasized by the current opioid epidemic in the United States where opioid analgesics are frequently abused and misused. It has been established that the effectiveness of opioids is maximized when these drugs readily access opioid receptors in the central nervous system (CNS). Indeed, opioid delivery to the brain is significantly influenced by the blood-brain barrier (BBB). In particular, ATP-binding cassette (ABC) transporters that are endogenously expressed at the BBB are critical determinants of CNS opioid penetration. In this review, we will discuss current knowledge on the transport of opioid analgesic drugs by ABC transporters at the BBB.

Classical inflammation is a well-characterized secondary response to many acute disorders of the central nervous system. However, in recent years, the role of neurogenic inflammation in the pathogenesis of neurological diseases has gained increasing attention, with a particular focus on its effects on modulation of the blood-brain barrier BBB. The neuropeptide substance P has been shown to increase blood-brain barrier permeability following acute injury to the brain and is associated with marked cerebral edema. Its release has also been shown to modulate classical inflammation. Accordingly, blocking substance P NK1 receptors may provide a novel alternative treatment to ameliorate the deleterious effects of neurogenic inflammation in the central nervous system. The purpose of this paper is to provide an overview of the role of substance P and neurogenic inflammation in acute injury to the central nervous system following traumatic brain injury, spinal cord injury, stroke, and meningitis.
