Candida albicans is an opportunistic fungal pathogen of humans. The cell wall of the organism defines the interface between the pathogen and host tissues and is likely to play an essential and pivotal role in the host-pathogen interaction. The components of the cell wall critical to this interaction are undefined. Immunoscreening of a lambda expression library with sera raised against mycelial ...

OBJECTIVE To uncover the specificities of autoantibodies to nuclear proteins (ANA) in patients with juvenile rheumatoid arthritis (JRA). METHODS Peptide ligands for ANA were selected by panning random peptide phage display libraries on antibodies binding to HEp-2 cells. Positive phage clones were identified by the immunoscreening technique. RESULTS Groups of peptides were identified, some o...

A mutation in the hydin gene has been recently described as one possible mechanism leading to lethal congenital hydrocephalus in mice, and a similar defect is proposed to be involved in an autosomal recessive form of hydrocephalus in human. Here, we report for the first time on the cancer association and immunogenicity of two HYDIN variants in humans. One is a previously described sequence deri...

Besides abundant oleosin, three minor proteins, Sop 1, 2, and 3, are present in sesame (Sesamum indicum) oil bodies. The gene encoding Sop1, named caleosin for its calcium-binding capacity, has recently been cloned. In this study, Sop2 gene was obtained by immunoscreening, and it was subsequently confirmed by amino acid partial sequencing and immunological recognition of its overexpressed prote...

OBJECTIVES Molecular mechanism of the pathogenicity of Enterococcus faecalis (E. faecalis), a suspected endodontic pathogen, has not yet been adequately elucidated due to limited information on its virulence factors. Here we report the identification of in vivo expressed antigens of E. faecalis by using a novel immunoscreening technique called change-mediated antigen technology (CMAT) and an ex...

P59Nc is a 59-kD polypeptide associated with 8-10-nm diameter cellular filaments in normal Neurospora crassa strains. Abnormally sized and shaped bundles of these structures are present in N. crassa strains carrying mutations at the locus sn (snowflake). By using molecular cloning and restriction fragment length polymorphism (RFLP) segregation analysis strategies we show here that sn is not the...

A cDNA encoding a putative tissue inhibitor of metalloprotease was cloned from an Ancylostoma caninum adult hookworm cDNA library by immunoscreening with anti-hookworm secretory products antiserum. Ac-TMP (A. caninum tissue inhibitor of metalloproteinase) is encoded by a 480-bp mRNA with a predicted open reading frame of 140 amino acids (molecular weight, 16,100 Da) that contains one potential ...

The pEX plasmids are a family of expression vectors for use in £. coB (1). Expression of cloned genes (as cro-lacZ fusion proteins) is controlled by the cI857 repressor gene. These vectors offer a number of dear advantages over other expression vectors; 1. Easy induction of gene expression (2 hours of Incubation at 42 *Q. Z A very high and consistent level of expression with virtually any open ...

BACKGROUND Urease B is an important virulence factor that is required for Helicobacter pylori to colonise the gastric mucosa. Mouse monoclonal antibodies (mAbs) that inhibit urease B enzymatic activity will be useful as vaccines for the prevention and treatment of H. pylori infection. Here, we produced murine mAbs against urease B that neutralize the enzyme's activity. We mapped their epitopes ...

The connecting cilium of photoreceptor cells is the only intracellular link between the morphologically, functionally and biochemically different compartments of the inner and outer segments. The non-motile modified cilium plays an important role in the organization and the function of photoreceptor cells, namely in delivery and turnover of enzymes and substrates of the visual transduction casc...
