Full textOpiates, such as morphine, are still the most powerful drugs in the management of pain. However, their chronic use induces tolerance, compelling to increase drug dose to obtain the same pharmacological effects and consequently raising the risk of adverse side effects, such as respiratory depression. As m-opioid receptors, d-opioid receptors are involved in analgesia and could participate to the development of tolerance. Accumulating evidence, indicate that tolerance could be initiated by a well-known cell process : desensitization. We conducted our study on the desensitization mechanisms of the human d-opioid receptor, endogenously expressed in the neuroblastoma SK-N-BE cells, activated by distinct opioid agonists. We demonstrated that : - d selective agonists (DPDPE, deltorphin I, SNC-80, AR-M1000390) induced a rapid desensitization (9̃0% for 30 min-pretreatment period) of d opioid receptor compared to non-selective agonists (etorphine, enkephalins) - selective agonists but AR-M1000390, that does not induce receptor sequestration, promoted internalization of d-opioid receptors followed by their degradation in the lysosomal compartment, whereas non-selective agonists induced mainly a recycling after internalization - etorphine-induced desensitization involves PKC and GRK2, while tyrosine kinases are required for desensitization produced by DPDPE and deltorphin. Conclusions : 1 - we demonstrated that d-opioid receptors undergo a differential desensitization, largely depending on the agonist selectivity 2 - the desensitization rate is rather depending on the fate of the opioid receptor, once internalized, than its sequestration from the plasma membrane 3 - the recruitment of different kinases would underlie the differential desensitization induced by selective and non selective agonist

Full textPain management is an urgent, unmet need. The International Association for the Study of Pain argues that pain is a public health issue as it is pervasive, disabling yet under-treated and very often under-diagnosed. It is estimated that 20% of adults experience moderate-to-severe pain, with pain being the leading cause of long-term disability. In addition, it is estimated that only 7.5% of people globally have access to adequate opioid analgesics when in need. Similarly, Zin notes that 92% of opioids globally are consumed by 17% of population. This is despite the fact that up to 2016, the use of opioids doubled every 10 years. This is a stark division of resources, often displayed as harmful overuse of opioid analgesics in some countries and harmful underuse in others.The inequities of pain treatment are well documented. The main causes of these inequities are lack of education, diverse access to treatments, and disproportionate use of pain treatments. Therefore, while pain treatment protocols may be developed, the underlying barriers to care must be addressed. Specifically, there is a lack of access to analgesics, but especially opioids, an essential medicine, in low- and middle-income countries. In many African countries, cancer incidence is increasing, and pain with it. Yet, access to certain treatment options such as opioid analgesics is severely restricted. Cleary et al. note that from their research on 25 of the 52 African countries “all of the surveyed countries in Africa have <10% of the anticipated Adequacy of Consumption Measure (ACM) for opioids”.The paucity of research on pain treatment in Africa is significant, and especially French-speaking Africa. The burden of disease, specific focus on cancer pain and the barriers to treatment in this context is under-researched. Significantly, this will continue to impact access to treatment, the development of policy and regulation to provide comprehensive care, and as disease burdens increase, the impact to social and economic development will persist. There is a need to understand how pain is assessed, treated, and managed in French-speaking Africa. A base of comprehensive data on which to design protocols, policies and programmes is lacking

Full textPain is a major problem in people with cancer. It is often under-reported, under-assessed and under-treated. This thesis aims, through two quantitative and qualitative approaches, to enrich the body of knowledge on the problem of undertreatment of pain in people with cancer and to explore the role of social and medical determinants in access to opioids. The results show a still high prevalence of pain, even 5 years after diagnosis, probably due to an undertreatment by opioids. They also show significant associations between patients’ socio-demographic and medical profile and access to opioids and palliative care. Our results therefore suggest the need to take into account the multidimensional nature of pain as well as the profile of patients in order to ensure comprehensive, multidisciplinary and equitable care

Full textPainful sensation is a hallmark of the inflammatory response induced by the infection by pathogens or tissue damage. Pro-inflammatory mediators released during inflammation directly activate primary sensory neuron to initiate painful message. This painful message is regulated in situ via the secretion of opioids by effectors CD4+ T lymphocytes generated in response to the pathogen. The analgesic properties of the CD4+ T lymphocytes are acquired upon activation by antigen loaded-dendritic cells in the draining lymph nodes via the de novo synthesis of enkephalin. Enkephalins are released by effector CD4+ T lymphocytes upon their arrival at the site of inflammation after new antigen stimulation with the cognate antigen. A defective regulation of CD4 + T cells in the intestinal mucosa can lead to the development of inflammatory bowel disease (IBD). My work shows in mice that Th1 and Th17 effector CD4+ T lymphocytes that are associated with IBD produce enkephalins. Using colorectal distension, I demonstrate that, during the acute phase of colitis, characterized by the activation of innate immune cells, mice exhibit visceral hypersensitivity. This hypersensitivity disappears in the later stages of the disease, when T cells infiltrate the inflamed mucosa. This inhibition of visceral hypersensitivity is dependent on the activation of the peripheral opioid receptors by the local release of enkephalins by CD4+ T cells. The intensity of visceral hypersensitivity appears to correlate with the rate of infiltration of the mucosa by T cells rather than the extent of tissue damage. This observation led us to develop a new anti-nociceptive strategy based on the recruitment of T cells at the early phase of colitis. The strategy that we adopted to accelerate the recruitment of T cells to the site of inflammation, was based on the establishment of a secondary immune response. I showed immunization of mice allowed, during a second exposure of to the antigen in the inflammatory site, reduce inflammatory visceral pain. This analgesic strategy was effective in both models of visceral pain that I have studied, the DSS-induced colitis in mice, and the cyclophosphamide-induced interstitial cystitis in rats. The use, in my protocol, of vaccines commonly used in human medicine allows considering rapid application in humans

Full textPainful sensation is a hallmark of the inflammatory response induced by pathogens or tissue damage. A large spectrum of molecules released within the inflamed tissue including neuropeptides, prostaglandins, or proteases induces pain by stimulating primary afferents in situ. Painful messages conveyed by primary sensitive fibers are modulated by peripheral endogenous regulatory mechanisms involving local opioïd release by leukocytes infiltrating the inflammatory site. Endogenous opioïd peptides belong to three families: endorphins, enkephalins, and dynorphins, which are derived from protein precursors encoded by three distinct genes: the proopiomelanocortin, the proenkephalin, and the prodynorphin genes, respectively. The biological activities of the opioïd neuropeptides are mediated by three types of seven transmembrane segment G-protein-coupled receptors named µ- (MOR), d- (DOR), and κ- (KOR) opioid receptors. ß-endorphin and enkephalins bind to both MOR and DOR, whereas dynorphin interacts only with KOR. Among immune cells infiltrating the inflammatory site, T lymphocytes have been described to be more efficient to relieve pain. We have quantified the expression level of mRNA encoding for all three opioïd precursors in dendritic cells, CD4+ and CD8+ T lymphocytes, B lymphocytes and macrophages in mice. We found that cell activation up-regulates proenkephalin mRNA level only in dendritic cells and CD4+ T lymphocytes. In activated CD4+ T lymphocytes, proenkephalin mRNA level were the highest, reaching more than 50% of that measured in brain, the main enkephalins producing organ. The role of T cell-mediated immunity in regulation of inflammatory pain was first appreciated by comparing nociceptive response to mechanical stimuli. T cell-deficient nude mice are more sensitive to inflammatory pain than wild-type mice. Normal sensitivity is restored by injection of naïve CD4+ T lymphocytes specific to the antigen responsible for inflammation. Analgesic property of CD4+ T lymphocytes is acquired in response to their specific antigen within draining lymph nodes, by de novo synthesis of enkephalins. Enkephalins production is irrespective of effector CD4+ T cell functions and is dependent upon specific antigen recognition at the inflammatory site. CD4+ T cell-induced analgesia is dependent on DOR activation on primary afferents. Enkephalins release by effectors CD4+ T cells within inflammatory site could also decrease dendritic cells migration to draining lymph nodes that contribute to T lymphocytes response reduction

Full textOpioid analgesics continue to be the cornerstones for treating moderate to severe pain. However, upon chronic administration, their efficiency is limited because of prominent side effects, such as tolerance and dependence. One hypothesis for the occurrence of these side effects is that the chronic stimulation of the opioid system may trigger its endogenous counterparts, anti-opioid systems, producing hyperalgesia and analgesic tolerance. Previous data from our lab and others suggest that RF-amide peptide receptors can modulate pain signalling through cross-interactions. We developed cell lines expressing fluorescent RF-amide receptors for the study of functional crosstalk and heterodimerization between RF-amide peptide receptors, i.e. GPR103 and NPFF1R. Through a productive collaboration with two teams of chemists, we identified and characterized multitarget peptidomimetic compounds that combined G protein-biased agonism and NPFFR antagonism. In accordance with in vitro results, we observed that acute subcutaneous administration of this compound produced long-lasting antinociceptive effects with less respiratory depression in mice. No hypersensitivity nor analgesic tolerance developed after chronic administration. Altogether, this molecule showed potent antinociceptive effect with limited side effects upon acute and chronic administration

Full textOpioids are still nowadays the most efficacious pharmacological compounds available to treat the different types of pain, and therefore provide a therapeutic analgesia. However, repeated administration of those compounds lead to major secondary effects like respiratory depression, tolerance, but also it was shown that some opioid compounds could induce seizures. From a therapeutical point of view, there is a serious need for new and better analgesic treatments that do not elicit such adverse effects. Our lab has been studying for years the signaletics of G-protein coupled receptors like the opioid receptors, and their capacity for functional selectivity, especially more recently the one of the delta opioid receptor (DOP). Indeed, this receptor elicits fewer adverse effects compared to the mu opioid receptor (MOP) that is the main target of all clinically used opioids such as morphine. However, it seems like the DOP itself would be responsible for the pro-epileptic states previously described. Thus, despite initial promises of the delta agonists towards reducing adverse effects whilst providing analgesia, the pro-convulsive effects that some seem to elicit have induced a loss of interest towards the DOP, and so far none of its agonists have gone further than pre-clinical trials. However, it has been shown that not all of those DOP agonists had those pro-convulsive adverse effects. How to explain such a phenomenon? This is the question which the present research will be asking. Thus our goal is to obtain and compare pharmacological signatures of the agonists known for being pro-convulsive versus those that are not ; regarding the transduction of signals through the delta opioid receptor and its heterotrimeric G-Protein ; and also regarding one of its main effectors to induce analgesia, an inwardly rectifying potassium channel. This comparison will be done according to the classical parameters of pharmacology, such as efficacy and potency ; but also according to the newest operational model, with parameters such as affinity and transduction coefficients. In order to do so, bioluminescence resonance energy transfer or BRET, will be used in order to characterize and quantify the signalling pathways there implicated. This research is embedded in a vast collaboration context, in between laboratories around the world, and within those laboratories as well, in hope to be able to one day synthesize, better pharmacological compounds, capable of targeting only the pathways responsible for the desired effects, here analgesia ; without triggering the associated adverse effects, here pro-convulsive states. The culmination of this research could allow to impact the lives of millions of people throughout the world, and this is why it is more than important for us to keep on pursuing it.
