  1. 1. Host-Pathogen Responses during Giardia infections

    Författare :Emma Ringqvist; Staffan Svärd; Patricia Johnson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Giardia; parasite infection; host-parasite releationship; immune activation; virulence factor; immune evasion; Cell and molecular biology; Cell- och molekylärbiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Sammanfattning : Giardia lamblia is a eukaryotic parasite of the upper small intestine of humans and animals. The infecting trophozoite cells do not invade the epithelium lining of the intestine, but attach to the brush border surface in the intestinal lumen. The giardiasis disease in humans is highly variable. LÄS MER

  2. 2. Structure, function and metabolic stability of antisense RNAs

    Författare :Fredrik Söderbom; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Sammanfattning : Antisense RNAs usually are small, highly structured, unstable RNAs that control a varietyof different biological processes. They exert their effect by binding to complementarytarget RNAs and thereby inhibit their functions. LÄS MER

  3. 3. Control of Chromosome and Plasmid Replication in Escherichia coli

    Författare :Jan Olsson; Kurt Nordström; Santanu Dasgupta; Måns Ehrenberg; Anders Lobner-Olesen; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Sammanfattning : Life is cellular. Cells grow and divide to give two new cells; this process is called the cell cycle. The chromosome in a bacterium is replicated into two identical copies before the cell divides. DNA replication is a fundamental process common to all forms of life. LÄS MER

  4. 4. CopA and CopT: The Perfect RNA Couple

    Författare :Jacoba G. Slagter-Jäger; Gerhart Wagner; Wolfgang Nellen; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Microbiology; antisense RNA; plasmid; U-turn; four-way junction; RNA-RNA interaction; Hfq; Mikrobiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Sammanfattning : Antisense RNAs regulate gene expression in many bacterial systems. The best characterized examples are from prokaryotic accessory elements such as phages, plasmids and transposons. Many of these antisense RNAs have been identified as plasmid copy number regulators where they regulate the replication frequency of the plasmid by negative feedback. LÄS MER
