001). [3H]GR65630 binding also increased in the ipsilateral entopeduncular nucleus and thalamus of 6-OHDA-lesioned rats with severe AIMs (75 % and 88 %, P less then 0.05). AIMs scores negatively correlated with [3H]GR65630 binding in the ipsilateral dorsolateral striatum and contralateral subthalamic nucleus (P less then 0.05). These results suggest that alterations in 5-HT3 mediated neurotransmission may contribute to the pathophysiology of l-DOPA induced dyskinesia.Cancer Immunotherapy relies on harnessing a patient's immune system to fine-tune specific anti-tumor responses and ultimately eradicate cancer. Among diverse therapeutic approaches, oncolytic viruses (OVs) have emerged as a novel form of cancer immunotherapy. OVs are a naturally occurring or genetically modified class of viruses able to selectively kill cancer cells, leaving healthy cells unharmed; in the last two decades, the role of OVs has been redefined to act beyond their oncolytic activity. Indeed, the immunogenic cancer cell death mediated by OVs induces the release of tumor antigens that in turn induces anti-tumor immunity, allowing OVs to act as in situ therapeutic cancer vaccines. Additionally, OVs can be engineered for intratumoral delivery of immunostimulatory molecules such as tumor antigens or cytokines to further enhance anti-tumor response. Moreover, OVs can be used in combination with other cancer immunotherapeutic approaches such as Immune Checkpoint Inhibitors and CAR-T cells. The current review first defines the three main mechanisms of action (MOA) of OVs currently used in cancer therapy that are i) Oncolysis, ii) OV-induced cancer-specific immune activation, and iii) Exploiting pre-existing anti-viral immunity to enhance cancer therapy. Secondly, we focus on how OVs can induce and/or improve anti-cancer immunity in a specific or unspecific fashion, highlighting the importance of these approaches. Finally, the last part of the review analyses OVs combined with other cancer immunotherapies, revising present and future clinical applications.In order to further elucidate the role of mesolimbic peptides in the expression of ethanol reward, the present study investigated the effects of ghrelin and glucagon-like peptide-1 (GLP-1) on ethanol intake, in addition to ethanol intake stimulated by systemic d-amphetamine or cocaine treatment. While a number of studies suggest that ghrelin plays an important role in mesolimbic reward, emerging data now indicate that GLP-1 receptor mechanisms inhibit reward signaling, possibly by directly or indirectly inhibiting ghrelinergic activity within the mesolimbic system. In the present study all rats were initially habituated to a 6% ethanol solution. We then demonstrated that intraperitoneal injections of d-amphetamine and cocaine increased ethanol intake compared to the vehicle condition. In subsequent testing we examined the effects of ventral tegmental area (VTA) ghrelin or vehicle paired with a fixed dose of d-amphetamine or vehicle. In separate rats we then investigated the impact of the GLP-1 agonist exendin-4 (Ex-4), injected into the VTA, on ethanol intake alone, or when Ex-4 was co-administered with d-amphetamine or cocaine. Our results indicated that VTA ghrelin significantly increased ethanol intake, and most importantly, potentiated the effect of d-amphetamine and cocaine on ethanol consumption. Conversely, VTA Ex-4 inhibited ethanol intake and antagonized the stimulatory effect of d-amphetamine and cocaine on ethanol consumption. Protoporphyrin IX mw In a final study we further demonstrated that VTA Ex-4 treatment significantly inhibited the combined stimulatory effects of ghrelin paired with d-amphetamine or ghrelin paired with cocaine. Overall our findings are consistent with a critical role for both ghrelin and GLP-1 receptor mechanisms in mesolimbic ethanol reward circuitry. Moreover, our results further suggest that ghrelin and GLP-1 modulate the stimulatory effect of psychostimulants on ethanol intake.Due to the financial burden and undesired side effects of treatment options, researchers have begun exploring alternative methods of treating autism spectrum disorder (ASD). Based on research suggesting impressive health benefits of engaging in physical activity, exercise treatment to alleviate symptoms could be a more cost effective alternative to pharmaceutical interventions. This study examined the effects of physical exercise on nociceptive responses and social interactions in an autism mouse model (BTBR T+ Itpr3tf/J). Subjects (n = 32) were separated into groups (BTBR vs B6 controls) based on the genetic strain and activity condition they were assigned. When compared to B6 controls, the BTBR mice demonstrated thermal hypoalgesia that normalized following 5 weeks of voluntary wheel running. However, exercise did not significantly attenuate social interaction deficits in BTBR mice, despite scores trending toward a positive direction. These results suggest that exercise could serve as a potential additive to other therapies for abnormal nociception in individuals with Autism Spectrum Disorder.Solvent additives, including NaCl, arginine hydrochloride (ArgHCl), glycine and sucrose, are used to enhance protein stability or reduce protein aggregation. Here, we studied the effects of these additives on proteins using agarose native gel electrophoresis. Since these additives are used at relatively high concentration, we first confirmed that they do not interfere with the performance of the native gel electrophoresis. Agarose native gel electrophoresis showed that aggregation of bovine serum albumin (BSA) induced by heating was slightly reduced by NaCl and ArgHCl. On the contrary, glycine and sucrose had marginal effects. ArgHCl and NaCl promoted heat aggregation of monoclonal antibody (mAb), while glycine and sucrose stabilized the native mAb. Arginine methyl ester inhibited heat aggregation of lysozyme and, to a much lesser extent, BSA. These results show that agarose native gel electrophoresis can be used to analyze the effects of solvent additives on proteins subjected to heat stresses. SYPRO Orange that stains only unfolded proteins confirmed unfolded structures of soluble aggregates.Here, we present highly porous, cellulose-based microspheres using (2,2,6,6-tetramethylpiperidine-1-oxyl) TEMPO-oxidized cellulose fibers (TOCFs) as starting materials. The TOCFs were first dissolved in a NaOH/urea solvent and transformed into microspheres via an emulsification method. The carboxyl groups on the surface of TOCFs were successfully carried on the cellulose-based microspheres, which provides them numerous reacting or binding sites, allowing them to be easily functionalized or immobilized with biomolecules for multi-functional applications. Furthermore, the introduction of magnetic nanoparticles awards these microspheres magnetic properties, allowing them to be attracted by a magnetic field. As a proof of concept, we demonstrate the application of using these carboxylate cellulose-based microspheres for enzyme immobilization. The cellulose-based microspheres can successfully create stable covalent bonds with enzymes after the activation of carboxyl groups. The enhanced pH tolerance, thermal stability, convenient recovery, and reusability position the emulsified microspheres as promising carriers for enzyme immobilization.Risk factors for cytomegalovirus (CMV) reactivation and the impact of CMV reactivation on patient outcomes have been extensively investigated after matched related or unrelated donor transplantation, but little is known in the setting of haploidentical stem cell transplantation (Haplo-SCT) with post-transplantation cyclophosphamide (PT-Cy), in which recipients are considered more severely immunocompromised. We retrospectively analyzed a cohort of 554 consecutive patients undergoing Haplo-SCT with PT-Cy at 3 different centers. Early CMV reactivation (occurring within the first 120 days post-transplantation) occurred in 242 patients, for an estimated cumulative incidence of 44%. Among those patients, 74 (30%) had recurrent CMV and 20 (8%) had CMV disease. On multivariable analysis, positive recipient CMV serostatus (hazard ratio [HR] >2.5; P less then .001), disease histology (lymphoid versus myeloid HR, 0.66; P = .003) and increasing recipient age (HR, 1.01; P = .015) were independent predictors of CMV reactivation. At a 4-month landmark analysis, CMV reactivation was associated with higher 1-year and 5-year cumulative incidence of nonrelapse mortality (NRM) relative to patients without reactivation 13% versus 5% and 22% versus 9%, respectively (P less then .001). On multivariable analysis, CMV reactivation was an independent negative predictor of NRM (HR, 2.69; P less then .001) and was close to statistically significant for overall survival (HR, 1.38; P = .062). Our results suggest that CMV reactivation plays an important role at determining NRM. Because patient CMV serostatus is the main predictor of CMV reactivation, it should be considered when evaluating strategies for preventing CMV reactivation. 2022 American Society for Transplantation and Cellular Therapy. Published by Elsevier Inc.The 2-step graft engineering approach has been the main platform for allogeneic hematopoietic cell transplantation (allo-HCT) at Thomas Jefferson University since 2005. We have previously described separating donor lymphocyte infusion followed by cyclophosphamide for bidirectional tolerization from CD34-selected hematopoietic grafts in haploidentical and matched related donors. Here we analyzed 60 patients with high-risk lymphoid malignancies who underwent a 2-step allo-HCT between 2008 and 2020. The majority of patients received haploidentical stem cell grafts (82%), and 20% of patients received matched related donor stem cell grafts. The patients underwent allo-HCT for diffuse large C cell lymphoma (n = 17; 28%), chronic lymphoblastic leukemia (n = 10; 17%), follicular lymphoma (n = 8; 13%), and Hodgkin lymphoma (n = 7; 12%). Eight patients (13%) had received prior high-dose chemotherapy. Thirty patients (50%) had a Hematopoietic Cell Transplantation Comorbidity Index ≥3, and 20 patients (33%) had a Center s in high-risk lymphoid malignancies, with rapid neutrophil and platelet recovery.Rapid advances in the field of hematopoietic cell transplantation (HCT), as well as the advent of immune effector cell therapy (IEC), have resulted in an increasing number of patients undergoing these therapies and an increasing level of expertise required to manage them. Previous guidelines for the training of HCT physicians were last published in 2012. In recognition of the expanding knowledge base and increasing skill set essential to the delivery of these treatment modalities, the American Society for Transplantation and Cellular Therapy Committee on Education has updated these guidelines to reflect nearly a decade of new knowledge in the field of HCT, as well as the evolution of IEC from an experimental modality to a widely used and mainstream therapy. The resulting document reflects the Committee on Education's recommended educational structure for programs engaged in the training, evaluation, and mentorship of HCT/IEC trainees.Fluoroquinolone prophylaxis during allogeneic hematopoietic stem cell transplantation (allo-HSCT) reduces bloodstream infections. However, this practice affects the gut microbiome and potentially increases dysbiosis, which is closely related to transplantation outcomes, and lower gastrointestinal (GI) tract acute graft-versus-host disease (GVHD). This study assessed the impact of omitting ciprofloxacin prophylaxis on GI GVHD, clinical outcomes, and microbiome composition in patients undergoing allo-HSCT. In this single-center, retrospective study comprising recipients of allo-HSCT performed between 2018 and 2020, routine ciprofloxacin prophylaxis (the exposure variable) was stopped in December 2018. The primary outcome was acute lower GI GVHD within 100 days post-transplantation; secondary outcomes were 1-year overall survival, nonrelapse mortality, relapse, and overall acute GVHD. Outcomes were compared using univariate and multivariate analyses and Kaplan-Meier/competing-risk analyses. Sequential stool samples were collected prospectively from a subpopulation of recipients, and the microbiome composition was analyzed.
