Immunotherapy of gastrointestinal cancers is challenging; however, several lines evidence suggest that adoptive transfer stimulated or modified immune cells support not only protective role in tumor microenvironment, but actively participate the elimination cancer cells.In vivo studies employing cell-derived allograft murine models were performed. The effects T helper (Th) 2 on growth and microenvironment composition using Th2 cells, interleukin (IL)-5 treatment, immunofluorescence,...

The pathogenesis of inflammatory bowel diseases (IBD) seems to be associated with alterations immunoregulation. Several lines evidence suggest that estrogens play a role in the modulation immune responses and may related etiology IBD. purpose this work was examine involvement G protein-coupled estrogen receptor (GPER), α (ERα), β (ERβ) ERα spliced variants ERα36 ERα46 Crohn’s disease (CD) ulcerative colitis (UC). studied group included 73 patients IBD 31 sex age-related controls.

Background: Current treatment of gastroesophageal reflux disease (GERD) is focused on decreasing the gastric acid secretion. However, there still a group patients not responding to conventional therapy. Proteinase-activated receptors and purinergic have been involved in inflammation, visceral hyperalgesia, esophageal hypersensitivity. The aim this study was evaluate expression PAR2 (F2RL1) P2RX2, P2RX3 P2RY2 GERD patients. Methods: studied quantified using real-time PCR biopsies with healthy...

Abstract Background An accumulating data suggest that the adhesion G protein-coupled receptor F5 (ADGRF5) is fundamental for human health and diseases1-3. It was noted ADGRF5 mediates immune response in cancers but its impact on colitis development still unknown. Moreover, recent findings identified mature tethered agonist of which corresponds to Stachel sequence this receptor4. The purpose work design peptides corresponding able activate with higher activity than evaluate them model....

Abstract Estrogens exert immunomodulatory action in many autoimmune diseases. Accumulating evidence highlights the meaningful impact of estrogen receptors physiology and pathophysiology colon. However, significance G protein-coupled receptor (GPER) on Crohn’s disease (CD), one inflammatory bowel (IBD) types, is still elusive. Our study revealed GPER overexpression at mRNA protein levels patients with CD. To evaluate effects activation/inhibition colitis development, a murine 2, 4,...

Cytokines are known to shape the tumor microenvironment and although progress has been made in understanding their role carcinogenesis, much remains learn regarding growth progression. We have identified granulocyte colony-stimulating factor (G-CSF) as one such cytokine, showing that G-CSF is linked with metastasis human gastrointestinal tumors neutralizing a mouse model of colitis-associated cancer protective. Here, we set out identify its receptor, G-CSFR, CD4+ CD8+ T cell responses...

Tumor-associated macrophages (TAMs) in the gastrointestinal tumor microenvironment (TME) are known to polarize into populations exhibiting pro- or anti-tumoral activity response stimuli such as growth factors and cytokines. Our previous work has recognized granulocyte colony-stimulating factor (G-CSF) a cytokine capable of influencing immune cells TME pro-tumoral activity. Here, we aimed focus on how G-CSF regulates TAM phenotype function effects (GI) progression. Thus, wildtype (WT)...

Ruthenium atoms located in the surfaces of carbosilane dendrimers markedly increase their anti-tumor properties. Carbosilane have been widely studied as carriers drugs and genes owing to such characteristic features monodispersity, stability, multivalence. The presence ruthenium dendrimer structure enhances successful use anti-cancer therapy. In this paper, activity generation 1 2 against 1301 cells was evaluated using Transmission Electron Microscopy, comet assay Real Time PCR techniques....

G protein-coupled receptor 30 (GPR30) is a recently de-orphanized estrogen that mediates the effects of estrogens on different cells. It has been postulated in inflammatory bowel diseases (IBD) activation GPR30 blocks pathways dependent pro-inflammatory cytokines.
