  2. 6. NK cell and dendritic cell interactions in innate immune responses

    Author : Catrine M Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NK cells; Dendritic cells; crosstalk; recruitment; activation; CD94 NKG2AQa1; Toxoplasma gondii;

    Abstract : Natural killer (NK) cells are cytotoxic cells of the innate immune system. They have been found to be critical in the defense against infections and also against some tumors. Recent studies have shown that NK cells require signals from accessory cells to induce their recruitment and activation at the site of infection or tumor growth. READ MORE

    Abstract : In allergic disorders, the eosinophilic granulocytes migrate to affected tissues and release granule proteins with cytotoxic, immunoregulatory, and remodeling-promoting properties. Given that degranulation is reflected by a loss in eosinophil granule density of living cells, or by cell membrane rupture and release of intact granules, these morphological changes may represent a biomarker of the allergic disease.

  6. 9. Ljungan Virus Replication in Cell Culture

    Author : Jens-Ola Ekström; Kjell Edman; Glyn Stanway; Högskolan i Kalmar; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ljungan virus; picornavirus; parechovirus; 5 - RACE; 5 -end; infectious cDNA clone; real time PCR; virus purification; virion stability; disinfection; aphthovirus-like 2A; Virology; Virologi; Mikrobiologi; Microbiology;

    Abstract : Ljungan virus (LV) is a recently identified picornavirus of the genus Parechovirus. LV has been isolated from voles trapped in Sweden and also in the United States. LV infected small rodents may suffer from diabetes type 1 and type 2 like symptoms, myocarditis and encephalitis. READ MORE

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

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

    Abstract : 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. READ MORE
