Candida albicans, a dimorphic fungus and an opportunistic pathogen, possesses a myriad of adherence factors including members of the agglutinin-like sequence (Als) family of mannoproteins. The adhesin Als5p mediates adhesion to many substrates, and is upregulated during commensal interactions, but is downregulated during active C. albicans infections[1]. An amyloid forming core sequence at residues 325-331 has been shown to be important for Als5p function, because a single amino acid substitution at position 326 (V326N) greatly reduces Als5p-mediated adherence[2]. We evaluated the role of Als5p in host-microbe interactions, using Caenorhabditis elegans as a host model and feeding them Saccharomyces cerevisiae expressing …

TGF-beta signaling is a conserved signaling pathway among eukaryotes, which controls various normal cellular responses from cell proliferation to cell death. The mutations in its components are found in developmental disorders and cancer. Therefore, this signaling pathway is extensively investigated so that new therapeutic targets could be discovered and novel drugs could be developed. Previous studies suggested the involvement of phosphatases in regulation of TGF-beta signaling, but these studies were performed in cell culture rather than intact organisms. C. elegans is a tractable organism in which to study signaling in vivo. In C. elegans, growth is controled by a conserved …
