Cytokine storm is one of main features during respiratory distress caused by COVID-19 infection. Acute Respiratory Distress Syndrome (ARDS) directly linked with elevated number mortality cases. Extreme amounts pro-inflammatory cells are found in the lung dead patients, mainly macrophages and IL-17 cells. A high level IL-6 was plasma patients indicated severity diseases. Some other chemokines, s...
Human bone stromal cells, after three-dimensional coculture with human prostate cancer (PCa) cells in vitro, underwent permanent cytogenetic and gene expression changes with reactive oxygen species serving as mediators. The evolved stromal cells are highly inductive of human PCa growth in mice, and expressed increased levels of extracellular matrix (versican and tenascin) and chemokine (BDFN, C...
TFF1, a mucin-associated secreted peptide of gastric mucous cells, is known as a protective agent for stomach epithelium under different stimuli, but its role upon Helicobacter infection is still not clear. In this paper we characterized TFFs expression, with particular attention to TFF1, under Helicobacter infection in gastric cell lines. A mouse model was used to distinguish TFF1 mRNA express...
In order to metastasize, cancer cells need to acquire a motile phenotype. Previously, development of this phenotype was thought to rely on the acquisition of selected, random mutations and thus would occur late in cancer progression. However, recent studies show that cancer cells disseminate early, implying the existence of a different, faster route to the metastatic motile phenotype. Using a s...
Aberrant TGFbeta signaling is common in human cancers and contributes to tumor metastasis. Here, we demonstrate that Gr-1+CD11b+ myeloid cells are recruited into mammary carcinomas with type II TGF beta receptor gene (Tgfbr2) deletion and directly promote tumor metastasis. Gr-1+CD11b+ cells infiltrate into the invasive front of tumor tissues and facilitate tumor cell invasion and metastasis thr...
Recruitment of neutrophils into alveolar air spaces is an early event in the pathogenesis of pneumonia due to Streptococcus pneumoniae. This results from chemokines released by activated endothelial and epithelial cells and alveolar macrophages. Culture supernatants of 6 wild-type strains of S. pneumoniae, shown to contain choline-binding protein A (CbpA; clades A and B), induced release of che...
The Th17 cytokine, IL-22, regulates host immune responses to extracellular pathogens. Whether IL-22 plays a role in viral infection, however, is poorly understood. We report here that Il22(-/-) mice were more resistant to lethal West Nile virus (WNV) encephalitis, but had similar viral loads in the periphery compared to wild type (WT) mice. Viral loads, leukocyte infiltrates, proinflammatory cy...
