  1. 21. Evolutionary genomics of host-microbe interactions

    Författare :Elin Videvall; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; host; microbiota; avian malaria; ostrich; parasite; dual RNA-seq;

    Sammanfattning : The microbes living inside hosts have highly important consequences for host health and fitness. From the host’s perspective, some microbes exhibit mutualistic tendencies, others parasitic, and some commensal, but this is context-dependent and opportunistic lifestyles are widespread in nature.

  3. 22. Avian Malaria and Interspecific Interactions in Ficedula Flycatchers

    Författare :William Jones; Anna Qvarnström; Rebecca Safran; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ficedula; flycatcher; avian malaria; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Sammanfattning : Parasitism is a core theme in ecological and evolutionary studies. Despite this, there are still gaps in our knowledge regarding host-parasite interactions in nature. LÄS MER

  4. 23. Immunological characteristics of recombinant fragments of the Plasmodium falciparum blood-stage antigen Pf332

    Författare :Halima A. Balogun; Klavs Berzins; Lars Hviid; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Plasmodium falciparum; Pf332; antibodies; immunity; growth inhibition; Immunology; Immunologi; immunologi; Immunology;

    Sammanfattning : Effective malaria vaccine might help improve control strategies against malaria, but the complexity of interactions between the parasite and its hosts poses challenges. The asexual blood stage P. falciparum antigen Pf332 has potentials as one of the proteins in understanding the complex host-parasite interactions. LÄS MER

  5. 24. Avian malaria, life-history trade-offs and interspecific competition in Ficedula flycatchers

    Författare :Katarzyna Kulma; Anna Qvarnström; Marlene Zuk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Blood parasites; competitive asymmetry; immunocompetence; interspecific competition; life-history trade-offs; MHC; parasite-driven selection;

    Sammanfattning : This thesis investigates the impact of avian malaria (Haemosporidia) parasites on the outcome of interspecific competition between two closely related bird species, pied (Ficedula hypoleuca) and collared (F. albicollis) flycatchers. LÄS MER

  7. 25. Inflammatory cell death of human macrophages induced by Aggregatibacter actinomycetemcomitans leukotoxin

    Författare :Peyman Kelk; Anders Johansson; Charels A Dinarello; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; leukotoxin; IL-1β; caspase-1; inflammatory cell death; pyroptosis; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Sammanfattning : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a bacterium mainly associated with aggressive forms of periodontitis. Among its virulence factors, a leukotoxin is suggested to play an important role in the pathogenicity. LÄS MER
