This killifish is capable of migrating overland and it could act as a transmission vector between otherwise isolated populations. Additional genetic markers are needed to confirm the presence of these cryptic Gyrodactylus species complexes, potentially leading to more in-depth genetic, ecological and evolutionary analyses on this
multi-host-parasite system.”
“Cerebral hypoxia/ischemia rapidly induces inflammation in the brain, which is characterized by microglial activation and the release of inflammatory cytokines. We have previously demonstrated that miR-181c can directly regulate tumor necrosis factor (TNF)-alpha production post-transcriptionally. Here, we determined that hypoxia up-regulated TLR4 expression
but down-regulated see more miR-181c expression in primary microglia. We also demonstrated that miR-181c suppresses TLR4 by directly KU 57788 binding its 30-untranslated region. In addition, miR-181c inhibited NF-jB activation and the downstream production of proinflammatory mediators, such as TNF-alpha, IL1b, and iNOS. Knocking down TLR4 in microglia significantly decreased TLR4 expression and inhibited NF-jB activation and the downstream production of proinflammatory mediators, whereas ectopic TLR4 expression significantly abrogated the suppressed inflammatory response induced by miR-181c. Therefore, our study identified an important role for the miR-181c-TLR4 pathway in hypoxic microglial activation and neuroinflammation. This pathway could represent a potential therapeutic target for cerebral hypoxic diseases associated with microglial activation and the inflammatory response.”
“There has been an increase this website in the cases of fungal resistance against many antifungal drugs and an effective alternative mode in the form of immunotherapy is being considered as new hope. The adhesion of Aspergillus fumigatus conidia to the host components is
one of the prime factors to cause aspergillosis. Carbohydrate components or glycoproteins present on the cell surface play an important role in interaction of the organism to the host and leads to adhesion. Any substance which is capable of disrupting this interaction may be a vital tool for the fungal clearance and hence may protect the host from infections caused by the fungus. In this study, a murine monoclonal antibody IgM generated against the secretory antigens of A. fumigatus, was found to be specific to a common epitope containing glycomoieties of the various proteins and exhibited anti-adhesive potential in vitro.
