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.
