Almost a decade has passed since the first report of RNA interference (RNAi) in a parasitic helminth. Whilst much progress has been made with RNAi informing gene function studies in disparate nematode and flatworm parasites, substantial and seemingly prohibitive difficulties have been encountered in some species, hindering progress. An appraisal ...

It is now clear that the epidermis has an active role in local immune responses in the skin. Keratinocytes are involved early in inflammation by providing first-line innate mechanisms and, in addition, can contribute to adaptive immune responses that may be associated with clinical disease. Moreover, keratinocytes are capable of ...

A novel murine enzyme, ADP-dependent glucokinase (ADPGK), has been shown to catalyse glucose phosphorylation using ADP as phosphoryl donor. The ancestral ADPGK gene appears to have been laterally transferred from Archaea early in metazoan evolution, but its biological role has not been established. Here, we undertake an initial investigation of ...
