Various species of the genus Pouteria (Elaeoluma) are used by the native population of Brazil because of, among other factors, their anti-inflammatory properties. The anti-inflammatory properties of the extract of the Amazonian plant Elaeoluma nuda were recently identified in prospective pharmacological studies.The objective of this study was to assess the anti-inflammatory effect of phonophoresis...
Irisin has recently been introduced as a novel an exercise-inducible myokine which improves glucose metabolism in mice. However, regulation of circulating irisin in gestational diabetes mellitus (GDM) and in the peripartal period has not been assessed so far.Circulating irisin was quantified in 74 GDM patients and in 74 healthy, pregnant, gestational age-matched controls. In a subset of these patients...
Recently, we reported that extracellular ubiquitin functions as another agonist of CXC chemokine receptor (CXCR)4. Whereas the cognate CXCR4 ligand, stromal cell-derived factor (SDF)-1α, is also a CXCR7 agonist, ubiquitin does not bind to CXCR7. Because both ligands are present in the extracellular environment, co-activation of CXCR4 appears to be physiologically relevant. CXCR4 mediated effects of...
Amongst host genetic factors, cytokine gene polymorphism can be anticipated to be an important factor as qualitative, quantitative and time of secretion play an important role in disease outcome. We have investigated association of cytokine promoter SNPs with risk of Plasmodium falciparum malaria and disease severity in a case control study in malaria endemic Karbi Anglong district of Assam, India...
Our previous study revealed that plasma visfatin levels were lower in pregnant women with gestational diabetes (GDM) than non-GDM independent of prepreganacy BMI. We examined whether central visfatin modulates energy and glucose homeostasis via altering insulin resistance, insulin secretion or islet morphometry in diabetic rats.Partial pancreatectomized, type 2 diabetic, rats were interacerbroventricularly...
Triggering receptor expressed on myeloid cells-1 (TREM-1) is an important receptor involved in the innate inflammatory response and sepsis. We assessed soluble TREM-1 (sTREM-1) in 112 septic neonates (63 culture-positive and 49 culture-negative) and 40 healthy controls as a potential early diagnostic and prognostic marker for neonatal sepsis (NS).Studied neonates were evaluated for early- or late-onset...
Epidemiological research on the relationship between single nucleotide polymorphisms (SNPs) in the IL5RA gene and allergic disorders is limited. We examined the relationship between IL5RA SNPs and risk of rhinoconjunctivitis in young adult Japanese women.Included were 393 women who met the criteria of the International Study of Asthma and Allergies in Childhood (ISAAC) for rhinoconjunctivitis. Controls...
Interleukin 17A (IL-17A) is a cytokine linked to inflammatory bowel disease. We investigated IL-17A expression in human colonic mucosa, whether IL-17A can elicit colonic mucosal damage in a human explant model and modulate gastrointestinal epithelial permeability in cell culture. We also tested if select cannabinoid ligands, shown to be protective in colitis models could attenuate damage caused by...
Circulating levels of leptin are elevated in type-2 diabetes mellitus (T2DM) and leptin plays a role in immune responses. Elevated circulating IL-18 levels are associated with clinical complications of T2DM. IL-18 regulates cytokine secretion and the function of a number of immune cells including T-cells, neutrophils and macrophages and as such has a key role in immunity and inflammation. Pro-inflammatory...
The chronic inflammatory state in sickle cell anemia (SCA) is associated with several factors such as the following: endothelial damage; increased production of reactive oxygen species; hemolysis; increased expression of adhesion molecules by leukocytes, erythrocytes, and platelets; and increased production of proinflammatory cytokines. Genetic characteristics affecting the clinical severity of SCA...
Previous studies identified the variant IFNG +874A/T (rs2430561) in the first intron of the gene in association with mycobacterial infection, especially tuberculosis and leprosy. The aim of this investigation was to analyze the protective role of the T allele in relation to leprosy using a meta-analysis evaluation. Thus, 1573 patients and 1914 controls were included and analyzed in fixed effects model...
Neutrophil microparticles (NMs) are scarce in the circulation but are highly enriched at sites of inflammation and exert profound effects on immune cells. In the present study, we addressed whether NMs modulate cytokine-producing capacity of natural killer (NK) cells. NMs inhibited the production of IFN-γ and TNF-α but enhanced the release of TGF-β1 by IL-2/IL-12-activated NK cells. The inhibitory...
Subgroups of patients with breast cancer may be at greater risk for cytokine-induced changes in cognitive function after diagnosis and during treatment. The purposes of this study were to identify subgroups of patients with distinct trajectories of attentional function and evaluate for phenotypic and genotypic (i.e., cytokine gene polymorphisms) predictors of subgroup membership. Self-reported attentional...
Leg ulcers (LUs) represent one of the main causes of morbidity in sickle cell anemia (SCA). This manifestation has been related to hemolysis, infections predisposition and inflammation that leads cytokines secretion. In this context, our study aimed to evaluate Th17 related cytokines (IL-6, IL-17A, IL-22 and IL-23) in serum and peripheral mononuclear cells culture supernatants with and without lymphoproliferative...
The purpose of this study was to identify the influence of vitamin D status (insufficient vs. sufficient) on circulating cytokines and skeletal muscle strength after muscular injury. To induce muscular injury, one randomly selected leg (SSC) performed exercise consisting of repetitive eccentric–concentric contractions. The other leg served as the control. An averaged serum 25(OH)D concentration from...
Polymorphisms of the interleukin-23 receptor (IL23R) gene have been found to play an important role in the development of several autoimmune diseases. We examined five susceptible (rs10889677, rs1004819, rs2201841, rs11805303, rs11209032), one protective (rs7517847) and two neutral variants (rs7530511, rs1884444) of the IL23R gene in pooled DNA of healthy Roma (Gipsy) and Hungarian population samples...
Aneuploidy, a condition associated with altered chromosome number, hence DNA index, is frequently seen in many diseases including cancers and affects immunity. Iron, an essential nutrient for humans, modulates the immune function and the proliferation of normal and cancer cells. To determine whether impaired immunity seen in iron-deficient subjects may be related to aneuploidy, we measured spleen...
Interleukin-17A (IL-17A) is the prototype of IL-17 family and has been implicated in the pathogenesis of a variety of autoimmune diseases. Therefore its structural and functional properties are of great medical interest. During our research on a recombinant human IL-17A (rhIL-17A) variant, four isoforms were obtained when it was refolded. While isoforms 1 and 2 represented non-covalent dimers, isoforms...
Our group and others have shown that serial intra-lesional injections of common warts with skin testing reagents such as Candida, mumps and Trichophyton are effective in regressing injected and non-injected warts. Anti-HPV T-cell responses appear to be induced. The goal of this study was to understand the mechanisms of how Candida skin testing reagent enhances immune responses.The following immunological...
