Abstract
Disruption of cellular activities by pathogen virulence factors can trigger innate immune responses. Interferon-γ (IFN-γ)-inducible antimicrobial factors, such as the guanylate binding proteins (GBPs), promote cell-intrinsic defense by attacking intracellular pathogens and by inducing programmed cell death. Working in human macrophages, we discovered that GBP1 expression in the absence of IFN-γ killed the cells and induced Golgi fragmentation. IFN-γ exposure improved macrophage survival through the activity of the kinase PIM1. PIM1 phosphorylated GBP1, leading to its sequestration by 14-3-3σ, which thereby prevented GBP1 membrane association. During Toxoplasma gondii infection, the virulence protein TgIST interfered with IFN-γ signaling and depleted PIM1, thereby increasing GBP1 activity. Although infected cells can restrain pathogens in a GBP1-dependent manner, this mechanism can protect uninfected bystander cells. Thus, PIM1 can provide a bait for pathogen virulence factors, guarding the integrity of IFN-γ signaling.

Abstract
The seroprevalence of IgG antibodies to Helicobacter pylori (Hp-Ab) was studied in 47 patients (29M, 18F, mean age +/- SD: 62.44 +/- 12.63 years) with non-cardia gastric carcinoma using an enzyme-linked immunosorbent assay. Controls were: a) 50 healthy people well-matched with the cancer patients; b) 50 patients with dyspepsia well matched with the cancer patients. Hp-Ab were detected in 72.3% of patients with gastric carcinoma, in 68% of healthy people and in 88% of dyspeptics. No significant associations were found between H. pylori infection and gastric cancer patients as a whole (odds ratio: 1.23, 95% CI: 0.514-2.95). In addition, no significant associations were found between H. pylori infection and the various subsets of cancer patients. These findings do not support an association between H. pylori infection and non-cardia gastric carcinoma in Greece.
