Hydroquinone (HQ, 1,4-benzenediol) is a hydroxylated benzene metabolite with various biological activities, including anti-oxidative, neuroprotective, immunomodulatory, and anti-inflammatory functions. However, the anti-cancer activity of HQ is not well understood. In this study, the in vitro and in vivo anti-cancer activity of HQ was investigated in various cancer cells and tumor-bearing mouse models. HQ significantly induced the death of A431, SYF, B16F10, and MDA-MB-231 cells and also showed a synergistic effect on A431 cell death with other anti-cancer agents, such as adenosine-2',3'-dialdehyde and buthionine sulfoximine...

PURPOSE: We performed a systematic review to quantify the amount of evidence-based data available on patient-reported outcomes (PRO) in Relapsed/Refractory Multiple Myeloma (RRMM) patients and to examine the added value of such studies in supporting clinical decision-making. METHODS: We conducted a search in PubMed/Medline and the Cochrane Library to identify studies published between January 1990 and May 2017. All studies, regardless of the design, including patients with RRMM and also evaluating PRO were considered...

Impaired healing of the skin is a notable cause of patient morbidity and mortality. In diabetic individuals, dysregulated inflammation contributes to delayed wound healing. Specific immunomodulatory agents may have a role in the treatment of diabetic wounds. One of these molecules is interleukin-1 receptor antagonist (Anakinra; Amgen Corp.). Although interleukin-1 receptor antagonist (Anakinra; Amgen Corp.) is approved by the Food and Drug Administration (FDA) for the treatment of rheumatoid arthritis and neonatal-onset multisystem inflammatory disease, little is known about the local use this drug in cutaneous wound healing...

Steroid-refractory chronic graft-versus-host disease (SR-cGVHD) remains a major cause of morbidity and mortality following allogeneic transplantation. Innovative immunotherapeutic strategies are urgently needed for the treatment of SR-cGVHD. We conducted a phase I clinical trial to evaluate the safety, efficacy, and immune effects of abatacept, a novel immunomodulatory drug that acts as an inhibitor of T cell activation via co-stimulatory blockade, in the treatment of SR-cGVHD. The study followed a 3+3 design with two escalating abatacept doses: 3 mg/kg and 10 mg/kg, with an expansion cohort treated at 10 mg/kg...

There is mounting scientific evidence showing the importance of innate biological rhythms on disease onset and progression. Perhaps the most important of these is the circadian rhythm, a cycle of oscillations lasting approximately 24 hours. Recent work has shown that circadian rhythms are intrinsically linked to the immune system in a bidirectional fashion, and disruption of these cycles can contribute to changes in pathology and quality of life (including fatigue, mood, and disability). This is particularly true in diseases of the nervous and immune systems...

Protein analysis in bone marrow samples from patients with multiple myeloma has been limited by the low protein concentration obtained after CD138+ selection. A novel approach based on capillary nano-immunoassay could make it possible to automatically quantify dozens of proteins from each myeloma sample. Here, we present a method for the accurate and robust quantification of the expression of multiple proteins extracted from CD138-purified multiple myeloma samples frozen in RLT Plus buffer, which is commonly used for nucleic acid preservation and isolation...

INTRODUCTION: Antigen-specific immunotherapy could provide a targeted approach for the treatment of multiple sclerosis that removes the need for broad-acting immunomodulatory drugs. ATX-MS-1467 is a mixture of four peptides identified as the main immune-dominant disease-associated T-cell epitopes in myelin basic protein (MBP), an autoimmune target for activated autoreactive T cells in multiple sclerosis. Previous animal studies have shown that ATX-MS-1467 treatment prevented the worsening of signs of disease in experimental autoimmune encephalitis (EAE) in the humanized (DR2 × Ob1)F1 mouse in a dose-dependent fashion...

The fecal microbiota is a rich source of biomarkers that have previously been shown to be predictive of numerous disease states. Less well studied is the effect of immunomodulatory therapy on the microbiota and its role in response to therapy. This study explored associations between the fecal microbiota and therapeutic response of Crohn's disease (CD) patients treated with ustekinumab (UST; Stelara) in the phase 2 CERTIFI study. Using stool samples collected over the course of 22 weeks, the composition of these subjects' fecal bacterial communities was characterized by sequencing the 16S rRNA gene...

Mutations in the cereblon ( CRBN ) gene cause human intellectual disability, one of the most common cognitive disorders. However, the molecular mechanisms of CRBN -related intellectual disability remain poorly understood. We investigated the role of CRBN in synaptic function and animal behavior using male mouse and Drosophila models. Crbn knockout (KO) mice showed normal brain and spine morphology as well as intact synaptic plasticity; however, they also exhibited decreases in synaptic transmission and presynaptic release probability exclusively in excitatory synapses...

BACKGROUND: The teratogenic effects of immunomodulatory and certain antimicrobial therapies are described in small rodents and humans. While the described teratogenic effects in small rodents have been extrapolated to make conclusions about its use in the pregnant dam, teratogenic effects of prednisone and doxycycline have not yet been reported in the dog. Here we report and describe midline defects observed in a litter of golden retriever puppies exposed to mid-gestational immunosuppressive and antimicrobial therapy...

Dry eye disease (DED), also known as keratoconjunctivitis sicca, is an ocular surface disease characterized by T-cell-mediated inflammation. Current therapeutics, such as immunosuppressive agents, act to suppress the clinical signs and inflammation. However, long-term usage of these treatments can cause severe side effects. In this study, we present an alternative therapeutic approach that utilizes a histone deacetylase inhibitor (HDACi) to regulate transcription of a variety of immunomodulatory genes. Specifically, HDACi have emerged as a potential anti-inflammatory agent, which can modulate the functions of a subset of suppressive T lymphocytes known as regulatory T cells (Tregs), enhancing FoxP3 acetylation and subsequently guarding the transcription factor from proteasomal degradation...

Nanoparticles create exciting platforms for anticancer immunotherapy and vaccination, though their inherent immunomodulatory properties have remained underexploited. Ammonio methacrylate copolymers (AMC) are well-established excipients in pharmaceutical industry and components of controlled-release oral formulations. Here, we demonstrate that nanoscaling of type A and B AMC (Eudragit® RL and RS) endows these inactive ingredients immunostimulatory properties exploitable for cancer therapy. The particles induce the secretion of various pro-inflammatory cytokines and chemokines from the cells of innate immunity...

4-(Nitrophenyl)hydrazone derivatives of N-acylhydrazone were synthesized and screened for suppress lymphocyte proliferation and nitrite inhibition in macrophages. Compared to an unsubstituted N-acylhydrazone, active compounds were identified within initial series when hydroxyl, chloride and nitro substituents were employed. Structure-activity relationship was further developed by varying the position of these substituents as well as attaching structurally-related substituents. Changing substituent position revealed a more promising compound series of anti-inflammatory agents...

Infection with seasonal influenza A virus (IAV) leads to lung inflammation and respiratory failure, a main cause of death in influenza infected patients. Previous experiments in our laboratory indicated that Bruton's tyrosine kinase (Btk) plays a substantial role in regulating inflammation in the respiratory region during acute lung injury (ALI) in mice, therefore we sought to determine if blocking Btk activity had a protective effect in the lung during influenza induced inflammation. A Btk inhibitor (Btk Inh...

Mucosal-associated invariant T (MAIT) cells are T cells that recognise vitamin-B derivative Ag presented by the MHC-related-protein 1 (MR1) antigen-presenting molecule. While MAIT cells are highly abundant in humans, their role in tumour immunity remains unknown. Here we have analysed the frequency and function of MAIT cells in multiple myeloma (MM) patients. We show that MAIT cell frequency in blood is reduced compared to healthy adult donors, but comparable to elderly healthy control donors. Furthermore, there was no evidence that MAIT cells accumulated at the disease site (bone marrow) of these patients...

BACKGROUND: Multiple myeloma (MM) is a plasma cell tumour with an approximate annual incidence of 4500 in the UK. Therapeutic options for patients with MM have changed in the last decade with the arrival of proteasome inhibitors and immunomodulatory drugs. Despite these options, almost all patients will relapse post first-line autologous stem cell transplantation (ASCT). First relapse management (second-line treatment) has evolved in recent years with an expanding portfolio of novel agents, driving response rates influencing the durability of response...

Aplastic anemia (AA) is generally considered as an immune-mediated bone marrow failure syndrome. Several studies show that bone marrow mesenchymal stem cells (BM-MSCs), as key cellular components of the bone marrow microenvironment, are also involved in the pathogenic mechanism of AA. Cyclosporin A (CsA) is a classic immunosuppressive drug for AA, and it specifically inhibits mammalian T cells by preventing activation of transcription factors involved in cytokine gene expression. However, little is known about the effect of CsA on the BM-MSCs...

PURPOSE OF REVIEW: Multiple myeloma treatment regimens consist of proteasome inhibitors (bortezomib, carfilzomib, and ixazomib), immunomodulatory drugs (thalidomide, lenalidomide, and pomalidomide), and steroids. In this paper, we will review the pathophysiology and associated cardiotoxicities of the different multiple myeloma therapeutic modalities and present methods to mitigate the development of cardiovascular complications. RECENT FINDINGS: Although proteasome inhibitors and immunomodulatory drugs have led to significant improvements in oncologic outcomes, there is increasing evidence of serious cardiovascular side effects which may be exacerbated in the setting of underlying cardiovascular risk factors or disease...
