Curcumin reduces Hodgkin's lymphoma (HL) cell growth in vitro, but its unfavorable pharmacokinetics highlight the need for novel in vivo delivery systems. Thus, we explored whether formulation of curcumin in solid lipid nanoparticles (SLN-curc) or d-α-Tocopheryl polyethylene glycol 1000 succinate (TPGS) nanoparticles (TPGS-curc) could enhance its efficacy in mice. Curcumin formulated in SLN and in TPGS resulted in higher curcumin plasma levels in mice. Compared to vehicle-treated controls, SLN-curc and TPGS-curc reduced HL xenograft growth by 50...

BACKGROUND: The proinflammatory cytokine interleukin-1β (IL-1β) drives pain by inducing the expression of inflammatory mediators; however, its ability to regulate sodium channel 1.7 (Nav1.7), a key driver of temporomandibular joint (TMJ) hypernociception, remains unknown. IL-1β induces cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2). We previously showed that PGE2 upregulated trigeminal ganglionic Nav1.7 expression. Satellite glial cells (SGCs) involve in inflammatory pain through glial cytokines...

Highly active anti-retroviral therapy (HAART) is very effective in suppressing HIV-1 replication in patients. However, continuous HAART is required to prevent viral rebound, which may have detrimental effects in various tissues, including persistent neuroinflammation in the central nervous system (CNS). Here, we show that quercetin (3,5,7,3',4'-pentahydroxy flavones), a natural antioxidant used in Chinese traditional medicines, suppresses the neuroinflammation that is induced by chronic exposure to Zidovudine (azidothymidine, AZT), a nucleoside reverse transcriptase inhibitor (NRTI) that is commonly part of HAART regimens...

Voltage-gated calcium channels (VGCCs) play a critical role in neuroinflammatory diseases, such as multiple sclerosis (MS). CTK 01512-2 is a recombinant version of the peptide Phα1β derived from the spider Phoneutria nigriventer, which inhibits N-type VGCC/TRPA1-mediated calcium influx. We investigated the effects of this molecule in the mouse model of experimental autoimmune encephalomyelitis (EAE). The effects of CTK 01512-2 were compared to those displayed by ziconotide-a selective N-type VGCC blocker clinically used for chronic pain-and fingolimod-a drug employed for MS treatment...

Intranasal vaccination of pigs with poly lactic-co-glycolic acid and polyanhydride nanoparticles delivered inactivated influenza virus provides cross-reactive T-cell response, but not antibody response, resulting in incomplete protection and no reduction in nasal virus shedding. Expression of BAFF and Th2 transcription factor GATA-3 were downregulated in lungs of pigs vaccinated with influenza nanovaccine, but in mice it upregulated the expression of BAFF and cytokine TGFβ in cervical lymph nodes. However, the intranasal iNKT cell adjuvant, α-Galctosylceramide upregulates the expression of BAFF in pig lungs...

Mycobacteriosis and nocardiosis in cultured fish caused by infections with acid-fast bacteria, are responsible for large economic losses globally. In this study, we suggest a novel adjuvant using glycolipids that activates host immune systems. The immune response to glycolipids stimulation was investigated using ginbuna crucian carp. Ginbuna vaccinated with FKC (formalin-killed cells) + glycolipids isolated from Mycobacterium sp., upregulated inflammatory- and Th1-related cytokines, and a DTH (delayed-type hypersensitivity) response was confirmed only in ginbuna vaccinated with FKC + glycolipids...

BACKGROUND: For head and neck squamous cell cancer (HNSCC), standard therapy consists of surgery, radiation, and/or chemotherapy. Antineoplastic immunotherapy could be an option in an adjuvant setting and is already in palliation. A functional immune system is a prerequisite for successful immunotherapy. However, effects of the standard-of-care therapy on the patients' immune system are not fully understood. METHODS: Peripheral blood mononuclear cells (PBMC) were collected from patients with HNSCC (n = 37) and healthy controls (n = 10)...

Cachexia in cancer patients, characterized by marked involuntary weight loss and impaired physical function, is associated with a poor prognosis in response to conventional treatment and with an increase in cancer-related mortality. Prevention of skeletal muscle loss under cancer-induced cachexia via inhibition of pro-cachectic factors, as well as a reduction in tumor mass, has been considered reasonable pharmacological and nutritional interventions to treat cancer patients. In this study, we constructed a novel herbal formula, SGE, which contains Ginseng Radix alba, Atractylodis Rhizoma alba , and Hoelen , examined its anti-cancer and anti-cachexia efficacies...

Approximately 5% of the healthy adult population respond inadequately to the commercial recombinant hepatitis B vaccines. As the recombinant vaccines all have an aluminum-based adjuvant, we tried to enhance the immune response by adding a cytokine-based adjuvant. This new adjuvant AI20, containing 20μg recombinant human IL-2 attached to 20μg aluminum hydroxide, was added to HBVaxPro©-10μg (HBAI20). In a double-blind randomized controlled trial (RCT), 24 naïve subjects were randomized to receive either HBAI20 or commercial HBVaxPro©-10μg vaccine...

The aim of this study was to evaluate the immunogenic and immunoprotective activities and to determine the neuroprotective capacity of the tetravalent vaccine containing selected recombinant T. gondii antigens (ROP2 + ROP4 + SAG1 + MAG1) administered with safe adjuvants (MPL and alum) using male and female inbred mice. The tested antigenic combination provided partial protection against brain cyst formation, especially in males (reduction in cyst burden by 72%). The decrease in cyst burden was observed for the whole brain as well as for specified brain regions associated with natural defensive behaviors, emotion processing and integration of motor and sensory stimuli...

REVIEW
Natalia Muñoz-Wolf, Ed C Lavelle
Growing awareness of the multiplicity of roles for the IL-1 family in immune regulation has prompted research exploring these cytokines in the context of vaccine-induced immunity. While tightly regulated, cytokines of the IL-1 family are normally released in response to cellular stress and in combination with other danger/damage associated molecular patterns (DAMPs), triggering potent local and systemic immune responses. In the context of infection or autoimmunity, engagement of IL-1 family receptors links robust innate responses to adaptive immunity...

Rheumatoid arthritis (RA) is a systemic inflammatory and autoimmune disease. In this research, we estimated the protective effects of Dihydromyricetin (DMY) on RA induced by Complete Freund's Adjuvant (CFA). We found that DMY effectively relieved rheumatoid arthritis symptoms, such as body weight change, paw swelling and rheumatoid arthritis scores. In addition, we also observed that DMY significantly lowered the immune organ indexes (including thymus and spleen) and exhibited the anti-inflammatory effect in CFA-induced rheumatoid arthritis...

BACKGROUND: Immunotherapy for food allergies involves progressive increased exposures to food that result in desensitization to food allergens in some subjects but not tolerance to the food. Therefore new approaches to suppress allergic immunity to food are necessary. Previously, we demonstrated that intranasal immunization with a nanoemulsion (NE) adjuvant induces robust mucosal antibody and TH 17-polarized immunity, as well as systemic TH 1-biased cellular immunity with suppression of pre-existing TH 2-biased immunity...

Development of a safe and efficacious vaccine for brucellosis is a long standing challenge for scientists. Recognizing potential antigens towards developing vaccine candidate is crucial. Omp25c, a porin protein of Brucella, is a paralog of two previously identified promising vaccine candidates namely, Omp25 and Omp31, with notable sequence identity. Also, Omp25c is conserved in all major Brucella species. This highlights the possibility of employing this protein in multivalent subunit vaccine based approach of Brucella management...

Cytokines are often used as adjuvants to improve vaccine immunogenicity, since they are important in initiating and shaping the immune response. The available commercial modified live-attenuated vaccines (MLVs) against porcine reproductive and respiratory syndrome virus (PRRSV) are unable to mount sufficient heterologous protection, as they typically induce weak innate and inadequate T cell responses. In this study, we investigated the immunogenicity and vaccine efficacy of recombinant PRRSV MLVs incorporated with porcine cytokine IL-15 or IL-18 gene fusing to a glycophosphatidylinositol (GPI) modification signal that can anchor the cytokines to cell membrane...

BACKGROUND: Epithelial ovarian cancer (EOC) remains the most lethal gynecologic malignancy. Primary cytoreductive surgery with adjuvant taxane-platinum chemotherapy is the standard treatment to fight ovarian cancer, however, their side effects are severe, and chemoresistance emerges at high rates. Therefore, EOC clinic urges for novel treatment strategies to reverse chemoresistance and to improve the survival rates. Metformin has been shown to act in synergy with certain anti-cancer agents, overcoming chemoresistance in various types of tumors...

Cytokines play vital roles in mounting immune responses and activating host defense network. In this study, the expression plasmid pcDNA3.1 (pcN3) encoding four flounder (Paralichthys olivaceus) cytokines including IL-1β, TNF-α, IL-8 or G-CSF (pcIL-1β, pcTNF-α, pcIL-8 and pcG-CSF) were successfully constructed, and their adjuvant potential on an Edwardsiella tarda (E. tarda) subunit vaccine OmpV (rOmpV) were comparatively analyzed in vaccinated flounder model. Results revealed that flounder vaccinated with rOmpV plus pcIL-1β, pcIL-8 or pcG-CSF produced the relative percent survivals (RPS) of 71%, 65% and 49% respectively, which were higher than that in flounder vaccinated with rOmpV plus pcTNF-α (39%) or pcN3 (36%, the control group)...

Autoimmune/inflammatory syndrome induced by adjuvant (ASIA) includes the following conditions: siliconosis, Gulf War syndrome, macrophagic myofasciitis syndrome, and post-vaccination phenomena. Afterward, other syndromes have been recognized, such as in ASIA by mineral oil (ASIA-MO). These conditions are triggered by adjuvants and they are the result of the interplay of genetic and environmental factors. ASIA-MO is defined as the infiltration of oily type modeling substances for cosmetic purposes. It has been reported in many countries and used surreptitiously...
