Cytomegalovirus seropositivity correlates with both human β-defensin 1 and IFN-γ downregulation in women with obesity.

Human β-defensin 1 (hBD-1) is a constitutively expressed antimicrobial peptide with antiviral properties. CMV seropositivity has been associated with obesity. It is unknown if hBD-1 levels of are altered in women with obesity and/or CMV seropositivity.

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.

Immunomodulatory Effect of Lactobacillus casei in a Murine Model of Colon Carcinogenesis.

We previously reported beneficial effects of the probiotic strain Lactobacillus casei 393 in hindering colon carcinogenesis in a 1,2-dimethylhydrazine (DMH)-induced BALB/c mouse model of colon cancer. In the present study, we investigated the effect of preventive administration of L. casei 393 on the levels of selected pro- and anti-inflammatory circulating cytokines, as well as subpopulations of splenic T cells.

Adaptive Memory of Human NK-like CD8 T-Cells to Aging, and Viral and Tumor Antigens.

Human natural killer (NK)-like CD8 T-cells are singular T-cells that express both T and NK cell markers such as CD56; their frequencies depend on their differentiation and activation during their lifetime. There is evidence of the presence of these innate CD8 T-cells in the human umbilical cord, highlighting the necessity of investigating whether the NK-like CD8 T-cells arise in the early stages of life (gestation). Based on the presence of cell surface markers, these cells have also been referred to as CD8KIR T-cells, innate CD8 T-cells, CD8CD28KIR T-cells or NKT-like CD8CD56 cells.
