Interleukin 17 (IL-17) family members are key players in regulating the immune response in mammals. Here, we identified the IL-17C and IL-17D homologs from large yellow croaker (Larimichthys crocea), named LcIL-17C and LcIL-17D, respectively. The deduced LcIL-17C and LcIL-17D proteins possessed the typical IL-17 domain and shared a conserved arrangement of eight cysteine residues. Both LcIL-17C and LcIL-17Dc genes were constitutively expressed in all tissues examined, although at different levels. After challenge with Aeromonas hydrophila, the expression of LcIL-17C and LcIL-17D was significantly increased in gills, head kidney, and spleen...

Neuroinflammation is a pervasive feature of Alzheimer's disease (AD) and characterized by activated microglia, increased proinflammatory cytokines and/or infiltrating immune cells. T helper 17 (Th17) cells are found in AD brain parenchyma and interleukin-17A (IL-17A) is identified around deposits of aggregated amyloid β protein (Aβ). However, the role of IL-17A in AD pathogenesis remains elusive. We overexpressed IL-17A in an AD mouse model via recombinant adeno-associated virus serotype 5 (rAAV5)-mediated intracranial gene delivery...

Increased understanding of the biology of interleukin 17 (IL-17) has revealed that this cytokine is a central player in immunity at the sites most exposed to microorganisms. Although it has been strongly associated with immunopathology, IL-17 also has an important role in host defense. The regulation of IL-17 secretion seems to be shared among various cell types, each of which can concomitantly secrete additional products. IL-17 has only modest activity on its own; its impact in immunity arises from its synergistic action with other factors, its self-sustaining feedback loop and, in some cases, its role as a counterpart of interferon-γ (IFN-γ)...

Shortly after the discovery of interleukin 17 (IL-17)-producing CD4(+) helper T cells (TH17 cells), it was found that γδ T cells can also secrete large amounts of this pro-inflammatory cytokine. A decade later, it is now known that IL-17(+) γδ T cells (γδ17 T cells) are often the main providers of IL-17A in various models of inflammatory diseases, while they also contribute to protective immune responses to infectious organisms. Due to an intricate thymic program of differentiation, γδ17 T cells are able to respond faster than TH17 cells do and thus predominate in the early stages of inflammatory responses...

As children age, they become less susceptible to the diverse microbes causing pneumonia. These microbes are pathobionts that infect the respiratory tract multiple times during childhood, generating immunological memory. To elucidate mechanisms of such naturally acquired immune protection against pneumonia, we modeled a relevant immunological history in mice by infecting their airways with mismatched serotypes of Streptococcus pneumoniae (pneumococcus). Previous pneumococcal infections provided protection against a heterotypic, highly virulent pneumococcus, as evidenced by reduced bacterial burdens and long-term sterilizing immunity...

Increased levels of interferon-γ (IFN-γ) are routinely observed in the respiratory tract following influenza virus infection, yet its potential role remains unclear. We now demonstrate that influenza-induced IFN-γ restricts protective innate lymphoid cell group II (ILC2) function in the lung following challenge with the pandemic H1N1 A/CA/04/2009 (CA04) influenza virus. Specifically, IFN-γ deficiency resulted in enhanced ILC2 activity, characterized by increased production of interleukin (IL)-5 and amphiregulin, and improved tissue integrity, yet no change in ILC2 numbers, viral load or clearance...

Gastric cancer is a world health problem and depicts the fourth leading mortality cause from malignancy in Mexico. Causation of gastric cancer is not only due to the combined effects of environmental factors and genetic variants. Recent molecular studies have transgressed a number of genes involved in gastric carcinogenesis. The aim of this review is to understand the recent basics of gene expression in the development of the process of gastric carcinogenesis. Genetic variants, polymorphisms, desoxyribonucleic acid methylation, and genes involved in mediating inflammation have been associated with the development of gastric carcinogenesis...
