BACKGROUND: Polyvalent human immunoglobulin G (IgG) preparations produced from the plasma pools of healthy blood donors have been used for the treatment of various autoimmune diseases and allergic diseases because of their anti-inflammatory and immunomodulatory effects. We hypothesized that intramuscular administration of autologous total IgG would induce immunomodulatory effects in patients with allergic diseases, based on the clinical efficacy of autologous blood therapy in patients with atopic dermatitis (AD)...

Nucleos(t)ide analogues (NAs) could successfully suppress hepatitis B virus (HBV) replication in patients with chronic hepatitis B (CHB). However, due to probable development of drug resistance or low/delayed response, these treatments may not be satisfactory. In addition to the HBV DNA polymerase inhibiting activity, these drugs could lead to changes in cytokines profiles. It is important to monitor these changes so that they could be used as target of treatment. Evaluating the previously reported immune responses due to NAs treatments, it was concluded that interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), interleukin-4 (IL-4), and IL-12 increase after the treatment...

Approximately one billion people are currently infected with hookworm. Despite its high prevalence and the concomitant immune suppression seen in infected individuals, little research has been done on the mechanism of immunosuppression by hookworm. Our study focused on characterizing mechanisms utilized by hookworm to suppress the host immune response. Splenocytes and draining lymph node cells from mice injected with hookworm excretory/secretory (ES) proteins showed decreased proliferation in response to both heterologous and species-specific antigens while also having increased nitric oxide secretion...

BACKGROUND & AIMS: Chronic hepatitis affects phenotypes of innate and adaptive immune cells. Mucosal associated invariant T (MAIT) cells are enriched in the liver as compared to the blood, respond to intra-hepatic cytokines, and (via the semi-invariant T-cell receptor) to bacteria translocated from the gut. Little is known about the role of MAIT cells in livers of patients with chronic hepatitis C virus (HCV) infection and their fate after antiviral therapy. METHODS: We collected blood samples from 42 patients with chronic HCV infection who achieved a sustained virologic response after 12 weeks of treatment with sofosbuvir and velpatasvir...

The roots of Euphorbia kansui, which belong to the family Euphorbiaceae, have been used as a traditional medicine for the treatment of various diseases such as diabetes, ascites, and leukemia. Recently, it was reported that the methylene chloride fraction of E. kansui radix (EKC) regulated the differentiation of Th17 cells and alleviated the symptoms of Th17-related inflammatory bowel disease. Imiquimod (IMQ), a TLR7/8 agonist, has been used to induce psoriasis in a mouse model. In this study, we evaluated the effect of EKC in an IMQ-induced psoriasis model...

Interleukin-10 (IL-10) induces an immunosuppressive microenvironment including M2 macrophages, inhibiting anti-tumor immunity. The aim of this study was to evaluate whether serum IL-10 level at diagnosis and tissue infiltration of M2 macrophages could predict survival outcome of patients with angioimmunoblastic T-cell lymphoma (AITL).We measured serum levels of IL-5, IL-10, IL-12, and interferon-gamma (IFN-γ) at diagnosis in AITL and other common subtypes of nodal T-cell lymphoma including peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), ALK-negative anaplastic large cell lymphoma (ALCL) or ALK-positive ALCL between September 2008 and December 2014...

AbstractMore than 2 billion people are infected with parasites globally, and the majority have coinfections. Intestinal protozoa and helminths induce polarizing CD4(+) T-helper cell 1 (Th1) mediated cytokine responses within the host. Such immune polarization may inhibit the ability of the host to mount an adequate immune response for pathogen clearance to concurrent pathogens. The current study evaluated the plasma cytokine profile in Ascaris and Giardia coinfected children compared with Giardia- and Ascaris-only infected children...

Interleukin-12 (IL-12) is formed by the interaction of IL-12p35 and IL-12p40 expressed independently from IL-12A and IL-12B genes. This interleukin plays prominent role in the T-helper type-1 (Th1) response against intracellular pathogens. Variations in IL-12B gene causes disruption of various activities one of them is suppression of Th1 response and is one of the characteristic features observed in patients with active tuberculosis. Hence, in the present study IL-12B gene status was evaluated in 50 new sputum smear-positive pulmonary tuberculosis patients (NSP-PTB) as identified by Ziehl-Nielsen (ZN) staining and 50 apparently healthy control subjects (HCS) who were sputum smear-negative...

Thirty-eight individuals (mean age: 34.8 years old) participating in a 3-month yoga and meditation retreat were assessed before and after the intervention for psychometric measures, brain derived neurotrophic factor (BDNF), circadian salivary cortisol levels, and pro- and anti-inflammatory cytokines. Participation in the retreat was found to be associated with decreases in self-reported anxiety and depression as well as increases in mindfulness. As hypothesized, increases in the plasma levels of BDNF and increases in the magnitude of the cortisol awakening response (CAR) were also observed...

Despite immense efforts, vaccine against visceral leishmaniasis has yet not been developed. Earlier our proteomic study revealed a novel protein, cofactor-independent phoshoglycerate mutase (LdiPGAM), an important enzyme in glucose metabolism, in T helper cells type 1 (Th1) stimulatory region of soluble Leishmania donovani antigen. In this study, LdiPGAM was biochemically and molecularly characterized and evaluated for its immunogenicity and prophylactic efficacy against L. donovani. Immunogenicity of recombinant LdiPGAM (rLdiPGAM) was initially assessed in naïve hamsters immunized with it by analysing mRNA expression of inducible nitric oxide (NO) synthase (iNOS) and other Th1/T helper cells type 2 cytokines, which revealed an upregulation of Th1 cytokines along with iNOS...

Rotavirus-related diarrhoea is considered one of the most important diseases in field animal production. In addition to the classic vaccine strategy, a number of studies have utilised probiotics, such as Lactobacillus rhamnosus GG (LGG), to prevent rotavirus-induced diarrhoea. Although it has been partially revealed that Toll-like receptors (TLRs) are involved in the LGG-mediated protection against rotavirus infection, the details of the underlying immunologic mechanisms remain largely unknown. In this study, three-to-four-week-old female BALB/c mice were divided into three groups and orally administered phosphate buffered saline (PBS), PBS plus rotavirus or LGG plus rotavirus, respectively...

BACKGROUND: Animal African trypanosomiasis (AAT) greatly affects livestock production in sub-Saharan Africa. In Ghana prevalence of AAT is estimated to range between 5 and 50%. Studies have reported serum biochemical aberrations and variability in cytokine profiles in animals during infection. However, information regarding the biochemical parameters and cytokine profiles associated with natural infections are limited. This study was therefore aimed at investigating changes in the levels of serum biochemical parameters and inflammatory cytokines during a natural infection...

Inflammation and the pro-inflammatory cytokines are associated with numerous chronic diseases. Studies suggest that flavonoids, plant polyphenolic compound derivatives from natural origin, have a wide range of putative biological activities. Similar to other flavonoids, chrysin (CH) by its anti-oxidative and anti-inflammatory effects is a potential prophylactic agent in immunopathological and physicochemical injuries. This is an overview on putative immunomodulatory activities of flavonoids and beneficial health effects of these substances particularly, CH in the immune system...

The purpose of this Opinion is to present a case for targeting sphingosine kinase 2 (SK2) in autoimmune/inflammatory disease. Data obtained using Sphk2(-/-) mice suggest that SK2 is an anti-inflammatory enzyme, although this might be misleading because of a compensatory increase in the expression of a second isoform, sphingosine kinase 1 (SK1), which functions as a proinflammatory enzyme. SK2 is involved in regulating interleukin (IL)-12/interferon gamma (IFN-γ) and histone deacetylase-1/2 (HDAC-1/2) signalling and, potentially, retinoid-related orphan receptor gamma t (ROR-γt) stability linked with T helper (Th) 17 cell polarisation...

Dietary choline is essential during lactation, but few studies have examined the implications of feeding a mixture of choline forms on immune function. This study investigates the impact of feeding lactating dams different mixtures of choline forms, similar to those in human diets, on the development and later immune function of suckled offspring. Sprague-Dawley lactating dams (n = 6/diet) were randomized to consume one of three diets, containing 1 g/kg choline: Control (100% free choline (FC)), Mixed Choline (MC: 50% phosphatidylcholine (PC), 25% FC, 25% glycerophosphocholine (GPC)), or High GPC (HGPC: 75% GPC, 12...

BACKGROUND: The signal transducer and activator of transcription-4 (STAT4/Stat4) is a transcription factor known to convey signals from interleukin-12, interleukin-23, and interferon-alpha/beta to the nucleus, resulting in activation of dendritic cells, T-helper cell differentiation and production of interferon-gamma. OBJECTIVE: To demonstrate a novel role for STAT4 in cell mitosis. RESULTS: Phosphoserine STAT4 (pSerSTAT4) is increased in cells undergoing mitosis, and is distributed throughout the cytoplasm during this stage of the cell cycle whilst phosphotyrosine STAT4 (pTyrSTAT4) is confined to the chromosomal compartment...

Platelet transfusion has been reported to modulate the recipients' immune system. To date, the precise mechanism(s) driving poor patient outcomes (e.g., increased rate of mortality, morbidity, infectious complications and prolonged hospital stays) following platelet transfusion are largely undefined. To determine the potential for platelet concentrates (PC) to modulate responses of crucial immune regulatory cells, a human in vitro whole blood model of transfusion was established. Maturation and activation of human myeloid dendritic cells (mDC) and the specialized subset blood DC antigen (BDCA)3(+) DC were assessed following exposure to buffy-coat derived PC at day (D)2 (fresh) and D5 (date-of-expiry)...
