  1. 1. Molecular population genetics of inducible defense genes in Populus tremula

    Author : Carolina Bernhardsson; Stefan Jansson; Santiago González-Martinez; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Populus; herbivore defense; adaptation; population genetics; population structure; association mapping; complex traits; evolutionär genetik; evolutionary genetics;

    Abstract : Plant-herbivore interactions are among the most common of ecological interactions. It is therefore not surprising that plants have evolved multiple mechanisms to defend themselves, using both constitutive chemical and physical barriers and by induced responses which are only expressed after herbivory has occurred.

    Abstract : Urinary tract infection (UTI) is among the most common bacterial infections in humans and the majority are caused by Escherichia coli (E. coli). Abundant evidence indicates that nitric oxide (NO) produced by the inducible NO synthase (iNOS) plays an important role in host defense against infection. READ MORE

  3. 3. Multiple stressors in rotifer communities: : Effects of predation, climate change, and brownification

    Author : Huan Zhang; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; community dynamic; brownification; heat wave; inducible defense; rotifer; plasticity; multiple stressors; Predation; prey;

    Abstract : Most organisms on Earth live in an environment where they are exposed to multiple pressures, including predation and climate change. In many aquatic ecosystems, organisms have to handle additional challenges such as brownification, co-occurring with climate warming. READ MORE

  4. 4. Post-Transcriptional Regulation of the Murine Inducible Nitric Oxide Synthase Gene

    Author : Malin Söderberg; Matti A. Lang; Françoise Raffalli-Mathieu; Eeva Moilanen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biochemistry; iNOS; inducible nitric oxide synthase; gene regulation; post-transcriptional; mRNA stability; RNA-protein interactions; dexamethasone; murine; heterogeneous nuclear ribonucleoprotein; hnRNPI; hnRNPL; Farmaceutisk biokemi; Pharmaceutical biochemistry; Farmaceutisk biokemi;

    Abstract : Large amounts of nitric oxide (NO) are produced by the inducible nitric oxide synthase (iNOS) upon inflammatory stimuli. NO is a multifaceted molecule, which may have beneficial effects as an antimicrobial agent in the immune defense, or cytotoxic effects in chronic inflammations, manifested as e.g. arthritis and asthma.

  5. 5. Antibacterial peptides - key players in host defense at epithelial surfaces

    Author : Mette Eliasson; allergologi och palliativ medicin Lungmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucosa; epithelium; pharyngitis; Innate immunity; Streptococcus pyogenes; antibacterial peptides; IFN-gamma; CXCL9 MIG; chemokines;

    Abstract : Innate host defense mechanisms at epithelial surfaces are important to prevent bacterial invasion. Streptococcus pyogenes, group A streptococcus (GAS), has an affinity for epithelial cells and cause pharyngitis. During streptococcal pharyngitis, high concentrations of the chemokines CXCL9/MIG, CXCL10/IP-10, CXCL11/I-TAC were found in tonsil fluid. READ MORE
