Monocytter, en klasse hvite blodlegemer i blodet, spiller en sentral rolle i kroppens immunforsvar og for blodets evne til å levre seg og danne en blodpropp. De kan ved stimulering, som ved sykelige tilstander, uttrykke vevsfaktor (TF) på celleoverflaten. TF er ansvarlig for å sette i gang blodproppmekanismen. En blodpropp kan dannes i kroppens samleårer (vener – kalles da dyp venøs trombose eller lungeemboli) eller årene som fører blodet ut fra hjertet (arterier - kalles da hjerteinfarkt eller hjerneslag). I denne avhandlingen har man studert hvordan den naturlige hemmeren til TF i monocytter, TFPI, påvirker monocyttenes evne til å sette i gang blodproppmekanismen og hvordan antall monocytter og deres evne til å uttrykke TF er forbundet med risiko for blodpropp. Man fant at monocyttene også uttrykte TFPI og at TFPI i sterk grad regulerte TF sin evne til å fremme blodproppdannelse. Videre fant man at både antall monocytter, deres evne til å uttrykke TF, og evne til å frigi blodproppfremmende mikropartikler var økt blant pasienter som senere utviklet blodpropp. Funnene er svært spennende og gir holdepunkter for at monocyttene og deres evne til å sette i gang blodproppdannelse kan spille en viktig rolle i sykdomsutviklingen av blodpropp. I framtiden kan det tenkes å være et angrepspunkt for medikamentell forebygging av blodpropp.

Prognostic Impacts of Angiopoietins in NSCLC Tumor Cells and Stroma : VEGF-A Impact Is Strongly Associated with Ang-2
Andersen, Sigve; Dønnem, Tom; Al-Shibli, Khalid Ibrahim; Al-Saad, Samer; Stenvold, Helge; Busund, Lill-Tove; Bremnes, Roy M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)Angiopoietins and their receptor Tie-2 are, in concert with VEGF-A, key mediators in angiogenesis. This study evaluates the prognostic impact of all known human angiopoietins (Ang-1, Ang-2 and Ang-4) and their receptor Tie-2, as well as their relation to the prognostic expression of VEGF-A. 335 unselected stage I-IIIA NSCLC-patients were included and tissue samples of respective tumor cells and ... -
The Temporomandibular Joint in Juvenile Idiopathic Arthritis, focusing on Quality of Life, Oral Microbiome and Intervention
Frid, Paula (Doctoral thesis; Doktorgradsavhandling, 2020-10-02)The temporomandibular joint (TMJ) is commonly involved in juvenile idiopathic arthritis (JIA), and may lead to impaired mouth opening, pain and facial growth disturbances. Asymptomatic TMJ arthritis may be diagnosed late in the disease course, thus management is challenging. The overall objectives of this thesis were to provide new knowledge on quality of life (QoL), the oral microbiome and interventions ... -
Humant papillomavirus : en litteraturstudie om HPV, dets relasjon til cancer og tiltak mot videre spredning av virus
Gabrielsen, Endre (Master thesis; Mastergradsoppgave, 2012-06-01)I 1983 oppdaget zur Hausen sammenhengen mellom Humant Papillomavirus (HPV) og livmorhalskreft. På denne tiden visste man ikke at det var HPV som var årsaken til at Helaceller kunne leve in vitro. Ny forskning relaterer HPV til en rekke andre cancertyper. En stor andel anal-, oropharyngeal-, penis-, vaginal-, og vulvacancer skyldes HPV. Det er også påvist HPV i tumorvev fra øsofagus, larynx, lunge, ...
