ConclusionsHigh UL111A expression changes the number of infiltrating T cells and is associated with favorable survival. Therefore, UL111A could be used as an independent prognostic biomarker and might be a potential therapeutic target for GC.

Publication date: August 2019Source: Current Opinion in Virology, Volume 37Author(s): Jonathan Stern, George Miller, Xin Li, Deepak SaxenaAlthough bacterial dysbiosis has been previously associated with carcinogenesis and HIV infection, the impact of the virome and these disease states has been less well studied. In this review, we will summarize what is known about the interplay between both the bacterial and the viral components of the microbiome on cancer and HIV pathogenesis. Bacterial dysbiosis has been associated with carcinogenesis such as colorectal cancer (CRC), hepatocellular carcinoma (HCC), lung cancer, breast ...

Conclusions and Future Perspectives It is now evident that NK/ILC family plays a pivotal role in the immune defenses. Recent studies in murine and human settings demonstrated that the expression of several inhibitory checkpoints, that may be detrimental in the tumor context, is not restricted to T lymphocytes, revealing an important, yet poorly appreciated, contribution of their expression on innate immune cells. Thus, in the recent years different immunotherapy approaches, based on the blockade of inhibitory NK cell receptors, have been developed in order to unleash NK cell cytotoxicity. This is particularly important in...

Conclusions Epidemiological studies have repeatedly helped identify definitive triggers for several diseases. As highlighted in this perspective report, previous studies strongly argue for the interplay between intrinsic factors and putative preventable extrinsic triggers/promoters for CTCL. Given the evidence of geographical regional clustering of CTCL patients, CTCL occurrence in unrelated family members and recent evidence implicating S. aureus in the pathogenesis/progression of CTCL, more research is needed to decipher the precise mechanism by which specific environmental exposures may be driving the pathogenesis of t...

The objectives this observational study were to determine the frequency of multiple infections by Helicobacter pylori, Epstein-Barr virus (EBV) and human cytomegalovirus (HCMV) and to relate the infection by EBV and HCMV with H. pylori vacA/cagA genotypes in patients with chronic gastritis or gastric cancer. DNA from H. pylori, EBV and HCMV was detected by PCR in biopsies from 106 Mexican patients with chronic gastritis and 32 from gastric cancer. The cagA status and the vacA genotypes of H. pylori were determined by PCR. In chronic gastritis and gastric cancer EBV was found in 69.8% and 87.5%, HCMV in 52.8% and 53.1%, and...

In conclusion, this is the first report to show that pyroptotic cell death occurs in the aging brain and that the inflammasome can be a viable target to decrease the oxidative stress that occurs as a result of aging. Reducing Levels of Protein Manufacture Slows Measures of Aging in Nematodes https://www.fightaging.org/archives/2018/12/reducing-levels-of-protein-manufacture-slows-measures-of-aging-in-nematodes/ Researchers here demonstrate that an antibiotic slows aging in nematode worms, providing evidence for it to work through a reduction in protein synthesis. Beyond a slowing of aging, one of the con...

Helicobacter pylori and Epstein-Barr virus are well established infections for gastric cancer development. However, the role of cytomegalovirus alone or in combination with other infections is unclear. In this case-control study the prevalence of different infections was evaluated and their frequency was compared with clinicopathologic features among gastric cancer patients and normal volunteers from 2012 to 2017. Approximately two-third (61.9%) of the gastric cancer patients had at least one viral infection, while viral infection prevalence in normal volunteers was only 4.7% (P = 0.021).

Increasing evidence suggests that human cytomegalovirus (HCMV) is associated with many human malignancies. However, its prevalence in gastric cancer (GC) and clinical association remain unknown. HCMV IgG and IgM antibodies in the sera of 80 GC patients and 80 healthy controls were detected using a microparticle enzyme immunoassay. The prevalence of HCMV UL47, UL55, UL56, and UL77 genes among 102 GC tumor tissues and adjacent normal specimens was measured by polymerase chain reaction (PCR) or nested PCR.

This study shows that the frequency of EBV-associated GC is high in Kerman. It also indicates that further studies of associations between GC and CMV are warranted, covering larger samples and populations from different areas of the world. PMID: 27268608 [PubMed - in process]
