Interpreting the Function of the IL-23/IL-17 Axis through Bioinformatics.

Introduction/objective: Bioinformatic analysis is a valuable tool that allows us to collect, archive, analyze, and disseminate biological data for further interpretation. Analysis of the IL-23/IL-17A axis and its receptors will provide us with essential information about their functions, interactions, and relationships with various diseases. This review aims to identify the central genes co-expressed in the IL-23/IL-17A axis and their receptors and to understand their ontology and modifying factors.

Association of polymorphisms in the TNFA, TNFRSF1A and TNFRSF1B genes with lepromatous leprosy in Western Mexican patients.

Introduction: Studies in different populations have shown that single-nucleotide polymorphisms (SNPs) of tumor necrosis factor-alpha (TNFα) and TNF receptors 1 and 2 (TNFR1 and TNFR2) may be involved in the pathogenesis of lepromatous leprosy (LL). To further explore the results in a Mexican population, we compared the frequencies of the polymorphisms in - 308 G>A TNFA (rs1800629), - 383 A>C TNFRS1A (rs2234649), and + 196 T >G TNFSR1B (rs1061622) genes in LL patients (n = 133) and healthy subjects (n = 198).

Methodology: The genotyping was performed with the polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) technique.

IL-23/IL-17 axis and soluble receptors isoforms sIL-23R and sIL-17RA in patients with rheumatoid arthritis-presenting periodontitis.

Background: Rheumatoid arthritis (RA) and periodontitis (P) are chronic inflammatory diseases characterized by joint and radiographic bone loss, respectively. IL-23 and IL-17 have an essential role in the immunopathogenesis of RA, and P. IL-23 stimulates Th17 cells through which produces IL-17, IL-21, and RANKL.

Inverse behavior of IL-23R and IL-17RA in chronic and aggressive periodontitis.

Purpose: Periodontitis is associated with a dysbiosis of periodontopathic bacteria, which stimulate the interleukin (IL)-23/IL-17 axis that plays an essential role in the immunopathogenesis of this disease, leading to alveolar bone destruction through receptor activator of nuclear factor κB ligand (RANKL). IL-23 receptor mRNA (IL-23R) has been identified in periodontitis, and IL-17 receptor A mRNA (IL-17RA) and its protein have not yet been evaluated in patients with periodontitis. In this study was measure IL-23R and IL-17RA in gingival tissue (GT) from patients with generalized chronic periodontitis (GCP) and generalized aggressive periodontitis (GAP) and to explore correlations with clinical parameters.

Innate and adaptive immunity of periodontal disease. From etiology to alveolar bone loss.

Periodontal disease refers to inflammation of the tissues that support the tooth. It is of multifactorial etiology. Innate and adaptive immune cells participate jointly through the release of their molecules and mechanisms of action in order to maintain homeostasis in periodontal tissues, so the host's immune response plays an essential role in defense against microorganisms.

Alteration of cytokines in saliva of children with caries and obesity.

Caries and obesity are multifactorial diseases with inflammatory components, whose processes involve cells and molecules, such as cytokines. Therefore, the objective of this work was to compare the concentrations of IL-6, IL-8, IL-15, and IL-18 in the salivary samples of children with caries and obesity. The study was carried out with 80 children: 43 with a normal weight and 37 with obesity.

Expression of ADAM10, Fas, FasL and Soluble FasL in Patients with Oral Squamous Cell Carcinoma (OSCC) and their Association with Clinical-Pathological Parameters.

ADAM10 has been implicated in the progression of various solid tumors. ADAM10 regulates the cleavage of the FasL ectodomain from the plasma membrane of different cell types, generating the soluble FasL fragment (sFasL). Currently, there are few studies in oral squamous cell carcinoma (OSCC) that correlate levels of ADAM10 and FasL in the tumor microenvironment with clinical parameters of the disease.

Increased number of micronuclei and nuclear anomalies in buccal mucosa cells from people exposed to alcohol-containing mouthwash.

The aim of this study was to evaluate the effects of alcohol-containing mouthwash on the induction of micronuclei and nuclear anomalies in exfoliated buccal cells, including binucleated cells, cells with nuclear buds, and karyolitic, karyorrhectic, condensed chromatin, and pyknotic cells. Buccal mucosa cells were collected from 107 healthy participants who were divided into three groups: control subjects who did not use mouthwash (n = 33), subjects who were exposed for 30 days and two times rinsing with 30 seconds each time to alcohol-containing mouthwash (n = 38; 26% ethanol concentration); and subjects exposed to a non-alcohol-containing mouthwash (n = 36). A slide was used to collect cells from the oral mucosa from the inner lining of both cheeks.

DNA and oxidative damages decrease after ingestion of folic acid in patients with type 2 diabetes.

Background And Aims: Type 2 diabetes mellitus (T2DM) is a chronic degenerative disease that promotes autoxidation of sugars, leading to the production of reactive oxygen species. This damage occurs especially at the level of cellular proteins, carbohydrates, lipids and DNA, thus playing an important role in the pathogenesis of late complications of T2DM. We investigated the effect of folic acid on DNA and oxidative damage in patients with T2DM.

Abnormalities in intracellular processing and expression of interferon-gamma receptor in adherent cells from lepromatous leprosy patients.

Peripheral blood mononuclear cells in lepromatous leprosy (LL) patients produce low levels of interferon-gamma (IFN-gamma) and interleukin-12 (IL-12), and these cells exhibit partial or complete deficiency in the IL-12 receptor. The behavior of the IFN-gamma receptor (IFN-gamma R) has not been described in cells from people with leprosy. We found higher levels of mRNA for IFN-gamma R1 and IFN-gamma R2 in adherent cells stimulated with IFN-gamma and Mycobacterium leprae membrane proteins from LL patients compared with healthy subjects.
