Project description:The illicit use of synthetic opioids such as fentanyl has led to a serious public health crisis in the United States. People with opioid use disorder are more likely to contract infections such as HIV and viral hepatitis. While several drugs of abuse are known to enhance viral replication and to suppress immunologic responses, the effects of synthetic opioids on HIV pathogenesis have not been investigated thoroughly. Thus, we examined the impact of fentanyl on HIV-susceptible and HIV-infected cell types and chemokine receptor expression in vitro. TZM-bl and HIV-infected lymphocyte cells were incubated with fentanyl at concentrations of 1 ng, 100 ng, and 10 ug. Expression levels of the CXCR4 and CCR5 chemokine receptors were measured in cell lysates, and HIV p24 antigen was quantified in culture supernatants by ELISA. HIV proviral DNA was quantified in cells using SYBR RT-PCR targeting the pol gene. Cell viability in the presence of drug was detected by the MTT Cell Proliferation Assay. RNA-seq and miRNAseq was performed to characterize cellular gene regulation in the presence of fentanyl. Fentanyl enhanced expression of CXCR4 and CCR5 protein levels in a dose-dependent manner in HIV-susceptible and HIV-infected cells. Similarly, fentanyl induced viral expression in HIV-exposed TZM-bl cells and in multiple HIV-infected lymphocyte cell lines. Multiple genes associated with apoptosis, antiviral / interferon response, chemokine signaling, and NFκB signaling were differentially regulated by fentanyl. These data demonstrate that the synthetic opioid fentanyl impacts HIV replication and chemokine co-receptor expression in HIV-susceptible and HIV-infected cells. Increased virus levels also suggest that opioid use may increase the likelihood of transmission to others and accelerate disease progression.

Project description:Here we examined virulence activation in Pseudomonas aeruginosa in response to the synthetic kappa opioid agonist U-50, 488 in nutrient poor media where growth conditions are limited and density dependent quorum sensing is not activated. We used a microarray to define the virulence-related genes in P. aeruginosa grown in liquid poor nutrient medium to determine the effect of kappa-opioid receptor agonist on virulence/lethal phenotype All biological samples for gene expression analysis were prepared in triplicate. P. aeruginosa MPAO1 cells collected from liquid culture at 7 hrs of growth in 1.) 0.1xTY medium containing tryptone 1 g/L and yeast extract, 0.5 g/L, or 2.) 0.1xTY+25 mM potassium phosphate buffer, pH 6.0, or 3.) 0.1xTY+200 uM U-50,488, or 4.) 0.1xTY+ 25 mM potassium phosphate buffer, pH 6.0+ 200 uM U-50,488 were used for RNA isolation. Microarray analysis was performed using Affymetrix P. aeruginosa GeneChips (Affymetrix, Santa Clara, CA) at the University of Chicago Functional Genomics Facility

Project description:To study the relationship between microRNAs and μ-opioid receptor (MOR) signaling, we examined microRNA expression after chronic morphine or fentanyl treatment in rat primary hippocampal neurons and in mouse hippocampus. Mouse cerebellum region was also tested as a negative control to eliminate microRNA expression changes unrelated to MOR signaling, as the cerebellum is essentially devoid of MOR. We identified a number of microRNAs that altered their expression upon treatment with both morphine and fentanyl in the rat and mouse systems. There were, however, some microRNAs that changed in response to morphine, or fentanyl, but not both. Keywords: Expression profiling There are up to three biological replicates (indicated by 1, 2, and 3) of primary hippocampal neurons from new born rats and the cerebellum and hippocampus regions from adult mice treated for three days (control, morphine, and fentanyl). The biological replicates were from experiments performed on different dates. Each biological replicate contained cells or tissues collected from multiple animals so that enough RNA could be extracted for RNA analysis. RNA was labelled with a green dye, mixed with a reference DNA sample labelled with a red dye. The reference DNA contained a number of synthetic DNA oligos with mature microRNA sequences that served to verify microarray hybridization. RNA signals were in ch1, DNA signals ch2.

Project description:Background: Opioid withdrawal is a key driver of opioid addiction and an obstacle to recovery. However, withdrawal effects on opioid reinforcement and mesolimbic neuroadaptation are understudied and the role of sex is largely unknown. Methods: Male (n=13) and female (n=12) rats responded under a fentanyl-vs.-food “choice” procedure during daily 2h sessions. In addition to the daily choice sessions, rats were provided extended access to fentanyl during 12h self-administration sessions. After two weeks of this selfadministration regimen, the nucleus accumbens (NAc) and ventral tegmental area (VTA) of a subset of rats were subjected to RNA sequencing. In the remaining rats, a third week of this self-administration regimen was conducted, during which methadone effects on fentanyl-vs.-food choice were determined. Results: Prior to opioid dependence, male and female rats similarly allocated responding between fentanyl and food. Abstinence from extended fentanyl access elicited similar increases in somatic withdrawal signs in both sexes. Despite similar withdrawal signs and extended access fentanyl intake, opioid withdrawal was accompanied by a maladaptive increase in fentanyl choice in males, but not females. Behavioral sex differences corresponded with a greater number of differentially expressed genes in the NAc and VTA of opioidwithdrawn females relative to males. Methadone blocked withdrawal-associated increases in fentanyl choice in males, but failed to further decrease fentanyl choice in females. Conclusions: These results provide foundational evidence of sex-specific neuroadaptations to opioid withdrawal, which may be relevant to the female-specific resilience to withdrawal-associated increases in opioid choice and aid in the identification of novel therapeutic targets.

Project description:Opioids analgesics are frequently prescribed in the United States and worldwide. However, serious side effects such as addiction, immunosuppression and gastrointestinal symptoms limit their use. It has been recently demonstrated that morphine treatment results in significant disruption in gut barrier function leading to increased translocation of gut commensal bacteria. Further study indicated distinct alterations in the gut microbiome and metabolome following morphine treatment, contributing to the negative consequences associated with opioid use. However, it is unclear how opioids modulate gut homeostasis in the context of a hospital acquired bacterial infection. In the current study, a mouse model of C. rodentium infection was used to investigate the role of morphine in the modulation of gut homeostasis in the context of a hospital acquired bacterial infection. Citrobacter rodentium is a natural mouse pathogen that models intestinal infection by enteropathogenic Escherichia coli (EPEC) and enterohemorrhagic E. coli (EHEC) and causes attaching and effacing lesions and colonic hyperplasia. Morphine treatment resulted in 1) the promotion of C. rodentium systemic dissemination, 2) increase in virulence factors expression with C. rodentium colonization in intestinal contents, 3) altered gut microbiome, 4) damaged integrity of gut epithelial barrier function, 5) inhibition of C. rodentium-induced increase in goblet cells, and 6) dysregulated IL-17A immune response. This is the first study to demonstrate that morphine promotes pathogen dissemination in the context of intestinal C. rodentium infection, indicating morphine modulates virulence factor-mediated adhesion of pathogenic bacteria and induces disruption of mucosal host defense during C. rodentium intestinal infection in mice. This study demonstrates and further validates a positive correlation between opioid drug use/abuse and increased risk of infections, suggesting over-prescription of opioids may increase the risk in the emergence of pathogenic strains and should be used cautiously. Therapeutics directed at maintaining gut homeostasis during opioid use may reduce the comorbidities associated with opioid use for pain management.

Project description:Opioid abuse poses significant risk to individuals in the United States and epigenetic changes are a leading potential biomarker of opioid abuse. Current evidence, however, is mostly limited to candidate gene analysis in whole blood. Here, we provide Illumina HumanMethylationEPIC array data generated in dorsolateral prefrontal cortex tissue from 153 deceased invidiuals: 72 who died of acute opioid intoxication, 53 psychiatric controls, and 28 normal controls. Using these data, we conducted an epigenome-wide association study and identified one CpG site within a gene (NTN1) that may be related to opioid use. We also detected accelerated PhenoAge in opioid samples compared to control samples.
