Rottemodellen af OA induceret af MIA er en veletableret, udbredt model. Intraartikulær injektion af MIA forårsager oprindeligt alvorlig og akut inflammation, hvilket giver anledning til den længere og degenerative fase af OA17,18. I denne forskning målte vi nociceptiv følsomhed ved MWT og TWL og vurderede gangændringer med et billeddannelsessystem. Tidligere rapporter viste, at injektionen af MIA kunne øge følsomheden af afferente knæledsfibre, hvilket f...

Slidgigt (OA) er den mest almindelige ledsygdom i verden og påvirker anslået 10-12% befolkninger hos voksne1. Det mest generelt involverede led er knæet, og OA har en højere forekomst hos ældre voksne, især kvinder2. Som en kronisk sygdom udvikler OA gradvist over årtier til ledsvigt med symptomer som brusktab, synovial inflammation, osteophytose, nedsat funktion og kronisk smerte3. Ifølge Verdenssundhedsorganisationen (WHO) er OA den fjerde mest udbredte sygdom hos kvinder og den ottende mest udbredte sygdom hos mænd. I 2020 kan OA blive den fjerde mest invaliderende sygdom hos mennesker4. Imidlertid behandler aktuelt tilgængelige behandlinger af OA kun symptomer og forlænger tiden indtil ledudskiftningskirurgi5.
Den spontane OA hos humane patienter tager ofte lang tid at producere kliniske symptomer såsom ledrelaterede smerter6. I de tidlige stadier af OA er smerter normalt intermitterende og bliver hyppigere og alvorligere, efterhånden som sygdommen skrider frem, hvilket gør det til den overvejende klage hos patienter7. Derfor er der udviklet omfattende dyremodeller for OA-smerter i løbet af det sidste halve århundrede for at fremme smertelindringsbehandling. OA-modeller er klassisk blevet opdelt i spontane og inducerede modeller. Spontane modeller omfatter naturligt forekommende modeller og genetisk modificerede modeller, som nærmere kan simulere forløbet af primær OA hos mennesker8. Inducerede modeller kan generelt opdeles i to kategorier: 1) posttraumatisk OA induceret af kirurgi eller andet traume; eller 2) intraartikulær injektion af kondrotoksiske eller proinflammatoriske stoffer3. Disse modeller danner grundlag for den patofysiologiske undersøgelse af OA og bidrager i høj grad til udviklingen af lægemidler til at reducere smerte og øge funktionen.
For nylig er den mest anvendte inducer til OA-modellering mono-iodoacetat (MIA). MIA, en hæmmer af glyceraldehyd-3-phosphatdehydrogenase, kan forårsage ændringer i bruskmatrix, nedbrydning, tab af brusk, synovitis og andre ændringer, der ligner de patologiske ændringer af human slidgigt9. Det er blevet bemærket, at intraartikulær injektion af MIA inducerede vedvarende smerter 28 dage efter MIA administration, hvilket indikerer, at MIA modellen kan være nyttig til undersøgelse af kroniske nociceptive smerter10,11,12. I denne undersøgelse modtog hanrotter fra Sprague-Dawley intraartikulære injektioner med 0,5, 1,5 eller 3 mg MIA i knæleddet. Sværhedsgraden af MIA-inducerede ledsmerter blev målt ved vurdering af mekanisk og termisk følsomhed ved 1, 7, 14, 21, 28 og 35 dage efter injektioner. På dette grundlag blev 1,5 mg MIA valgt som den endelige koncentration til evaluering af gangmønstre og histologiske ændringer 28 dage efter injektioner.

osteoarthritis pain model induced by intra-articular injection of mono-iodoacetate in rats

De nuværende dyremodeller for slidgigt (OA) kan opdeles i spontane modeller og inducerede modeller, som begge sigter mod at simulere de patofysiologiske ændringer af human OA. Men som det vigtigste symptom i den sene fase af OA påvirker smerter patienternes daglige liv, og der er ikke mange tilgængelige modeller. Den mono-iodoacetat (MIA) -inducerede model er den mest anvendte OA smerte model, hovedsagelig anvendt i gnavere. MIA er en hæmmer af glyceraldehyd-3-phosphatdehydrogenase, som forårsager chondrocytdød, bruskdegeneration, osteofyt og målbare ændringer i dyreadfærd. Desuden kan ekspressionsændringer af matrixmetalloproteinase (MMP) og proinflammatoriske cytokiner (IL1 β og TNF α) detekteres i den MIA-inducerede model. Disse ændringer er i overensstemmelse med OA patofysiologiske tilstande hos mennesker, hvilket indikerer, at MIA kan fremkalde en målbar og vellykket OA smertemodel. Denne undersøgelse har til formål at beskrive metoden til intraartikulær injektion af MIA hos rotter og diskutere den resulterende smerterelaterede adfærd og histopatologiske ændringer.

Med denne metode etablerede vi en OA-smertemodel hos rotten og opdagede de resulterende ændringer. MWT og TWL reflekterede henholdsvis mekanisk allodyni og termisk hyperalgesi. Som vist i figur 1 var MIA induceret mekanisk allodyni og termisk hyperalgesi til stede på en dosisafhængig måde. Bemærkelsesværdigt nåede faldet i MWT et højdepunkt fra 21 dage til 28 dage og steg derefter igen, hvilket tyder på, at fælles reparation kan forekomme på dette stadium, men MWT på 3 mg MIA-gru...
