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:The illicit use of synthetic opioids such as fentanyl has led to a serious public health crisis in the US. People with opioid use disorder are more likely to contract infections such as HIV and viral hepatitis and experience more severe disease. 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 macrophage cell line U937 and monocyte derived macrophage cells and chemokine receptor expression in vitro.

Project description:Opioid use is associated with worse outcome in HIV-infected patients. The exacerbated disease progression by opioids is mainly driven by increased epithelial damage and less regenerative response. The present study investigates how opioids potentiate HIV disease progression by impairing intestinal epithelial self-repair. Abnormal intestinal morphology and reduced epithelial proliferation were observed in HIV-infected humanized mice, which were exposed to opioids. For this study, we had 4 groups of BLT humanized mice- (A) Untreated, (B) Morphine treated, (C) HIV infected and (D) HIV infected + Morphine treated. HIV infection was done for 4 weeks and Morphine treatment was done for 7 days. Morphine treatment was done via subcutaneous implantation of slow-release morphine pellet in individual mouse in the appropriate groups. In other groups, a matching Placebo pellet was implanted.

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:Due to the current opioid epidemic, a better understanding of genetic and environmental factors that contribute to opioid addiction is warranted. To explore the potential causative role of VitD in opioid addiction , we used multiple pharmacologic approaches and genetic mouse models. We used profiled the transcriptome of key brain reward regions upon morphine treatment in vitamin D receptor KO and wild type mice. Our results highlight the role of VitD deficiency in the development of addiction and suggest a potential therapeutic benefit of VitD supplementation for VitD deficient individuals in the prevention and management of addiction.

Project description:Opioids are commonly prescribed to patients with advanced clear cell renal cell carcinoma for extended periods of time in assistance for pain management. Because extended opioid exposure has been shown to affect the vasculature and to be immunosuppressive, we investigated how it may affect the metabolism and physiology of advanced clear cell renal cell carcinoma. RNA sequencing of archived patient’s specimens with extended opioid exposure or non-opioid exposure were peformed.

Project description:The opioid receptors are important regulators of pain, reward, and addiction. Limited evidence suggests the mu and delta opioid receptors form a heterodimer (MDOR), which may act as a negative feedback brake on opioid-induced analgesia. However, evidence for the MDOR in vivo is indirect and limited, and there are few selective tools available. We recently published the first MDOR-selective antagonist, D24M, allowing us to test the role of the MDOR in mice. We thus co-treated CD-1 mice with D24M and opioids in tail flick, paw incision, and chemotherapy-induced peripheral neuropathy pain models. D24M treatment enhanced oxymorphone anti-nociception in all models by 52.3%-628%. This enhancement could not be replicated with the mu and delta selective antagonists CTAP and naltrindole, and D24M had a mild transient effect in the Rotarod test, suggesting this increase is selective to the MDOR. However, D24M had no effect on morphine or buprenorphine, suggesting that only specific opioids interact with the MDOR. To find a mechanism we performed phosphoproteomic analysis on brainstems of mice. We found that the kinases Src and CaMKII were repressed by oxymorphone, which was restored by D24M. We were able to confirm the role of Src and CaMKII in D24M-enhanced anti-nociception using small molecule inhibitors (KN93, Src-I1). Together these results provide direct in vivo evidence that the MDOR acts as an opioid negative feedback brake, which occurs via the repression of Src and CaMKII signal transduction. These results further suggest that MDOR antagonism could be a means to improve clinical opioid therapy.

Project description:The heterogeneity and rarity of HIV-1-infected cells hampers effective cure strategies. We used single-cell DOGMA-seq to simultaneously capture transcription factor accessibility, transcriptome, 156 surface proteins, HIV-1 DNA, and HIV-1 RNA from six HIV-1+ individuals during viremia and after suppressive antiretroviral therapy. We identified 252 transcriptionally inactive (HIV-1 DNA+ RNA–) and 270 transcriptionally active (HIV-1 RNA+) HIV-1-infected cells from 82,549 memory CD4+ T cells. We identified increased transcription factor accessibility in HIV-1 DNA+ RNA– cells (RORC) and HIV-1 RNA+ cells (IRF and AP-1), in addition to CNC and MAF in both. Both HIV-1 DNA+ RNA– and HIV-1 RNA+ cells upregulate IKZF3 (Aiolos) that correlates with proliferation of HIV-1-infected cells. We revealed that the heterogeneous HIV-1-infected T cells comprise four distinct immune programs driven by epigenetic regulators – IRF-activation, Eomes-cytotoxic effector, AP-1-migration, and cell death. Our study revealed the single-cell epigenetic, transcriptional, and protein states of transcriptionally inactive and active HIV-1-infected cells.
