Reumatologi

Reumatiska sjukdomar är vanliga och orsakas av en oförmåga i immunsystemet att skilja på kroppsegna och kroppsfrämmande ämnen. Detta kan leda till en immunologisk attack på kroppens organ, exempelvis leder, salivkörtlar, hud eller njurar. Det övergripande målet för reumatologins forskargrupp är att förstå de bakomliggande orsakerna till uppkomsten och utvecklingen av olika reumatiska sjukdomar. På sikt kan sådan kunskap leda till bättre diagnostiska metoder och behandlingar och därmed förbättra omhändertagandet och prognosen för dessa patientgrupper.
Beskrivning av vår forskning

Gemensamt för de reumatiska sjukdomarna är att sjukdomsmanifestationerna kan variera stort även inom samma diagnos. Vår forskning syftar bland annat till att identifiera riskfaktorer för de olika organmanifestationerna och de bakomliggande mekanismer som bidrar till att vissa drabbas av svårare sjukdom än andra.
Vi studerar bland annat betydelsen av arvsanlagen, hur dessa regleras och uttrycks i olika celler och vävnader, samt vilka proteiner i blodet som kan vara av betydelse för sjukdomsbilden. Med experimentella analyser studeras sjukdomsmodifierande mekanismer.
Våra huvudsakliga forskningsområden är fokuserade på systemisk lupus erytematosus (SLE), Sjögrens sjukdom, Systemisk skleros samt ANCA-associerade vaskuliter. Mekanismerna bakom den ökade risken för lymfom hos patienter med vissa reumatiska sjukdomar undersöks ur flera aspekter. IgG4-relaterad sjukdom studeras avseende kliniska manifestationer och nya diagnostiska metoder.
Forskargruppen i reumatologi leds av professor Gunnel Nordmark. Seniorprofessor är Lars Rönnblom. Övriga seniora forskare är docenterna Dag Leonard, Maija-Leena Eloranta, Johanna Dahlqvist, Ann Knight och Eva Baecklund. Vidare består forskargruppen av disputerade forskare, post-doktorer, doktorander, studenter, bioinformatiker, forskningsingenjör och en forskningssköterska.
