Interleukin-1 beta single-nucleotide polymorphism's C allele is associated with elevated risk of gastric cancer in Helicobacter pylori-infected Peruvians.
Enhanced gastric IL-18 mRNA expression in Helicobacter pylori-infected children is associated with macrophage infiltration, IL-8, and IL-1 beta mRNA expression.
Furthermore, nucleofection experiments were established to introduce this inhibitory peptide into the nucleus of IL-1 stimulated human cervical and Helicobacter pylori infected gastric epithelial cells.
Gastric mucosal IL-1β levels were also persistently elevated in group P, and neutralisation of IL-1β reduced the HP-specific IL-17A response of purified CD4(+) T cells to autologous HP-pulsed antigen presenting cells in vitro, suggesting a functional association between IL-1β and the persistent Th17 response in group P patients.
Host genetic factors that control the production of cytokines, including interleukin-1β (IL-1β), possibly affect susceptibility to many Helicobacter pylori-related diseases.
Induction of TNF, CXCL8 and IL-1β in macrophages by Helicobacter pylori secreted protein HP1173 occurs via MAP-kinases, NF-κB and AP-1 signaling pathways.
Inflammasome activation and caspase-1-dependent (CASP1-dependent) processing and secretion of IL-1β and IL-18 are critical events at the interface of the bacterial pathogen Helicobacter pylori with its host.
OPN KD gastric cancer cell lines also showed lower proliferative activity and reduced MAPK activation than shRNA control cells after HP co-culture or after IL-1β and TNF-α treatment.
Our aim was to explore potential interactions among dietary (chili pepper consumption), infectious (Helicobacter pylori) and genetic factors (IL1B-31 genotypes) on GC risk.
Our previous study revealed that a polymorphism of the interleukin (IL) 1B gene, encoding the pro-inflammatory cytokine IL-1 beta, influenced the prevalence of persistent Helicobacter pylori (HP) infection.
Polymorphisms of IL-1 gene cluster are reported to be associated with histological changes and IL-1β expression in the gastric mucosa in adults, especially in Helicobacter pylori-infected subjects.
Polymorphisms of the IL1B gene have been associated with gastric atrophy and increased cancer risk, especially in Helicobacter pylori-infected subjects.
Recent investigations have indicated that produced inflammatory cytokines such as TNF-α and IL-1β in response to gastric infection by Helicobacter pylori play an important role in the development of peptic ulcer.
Role of host interleukin 1beta gene (IL-1B) and interleukin 1 receptor antagonist gene (IL-1RN) polymorphisms in clinical outcomes in Helicobacter pylori-positive Turkish patients with dyspepsia.
