A máj által termelt fetuin-A (eredeti nevén α2-Heremans–Schmid-glikoprotein) szerteágazó funkciókkal bíró molekula. Bár negatív akutfázis-fehérje, szerepe a szubklinikus gyulladásban vitatott. Gátolja az inzulinreceptor autofoszforilációját, szérumkoncentrációja korrelál az inzulinrezisztenciával. A zsírsejtek működészavarát okozza. Szérumszintje összefügg az elhízással és a nem alkoholos zsírmájbetegséggel. Bár ezen tulajdonságai alapján azt várnánk, hogy az atherosclerosis progresszióját segíti, cardiovascularis betegségekben játszott szerepe ennél összetettebb. A fetuin-A a szöveti és a vascularis kalcifikáció természetes gátlómolekulájaként az atherosclerosisban védő szerepet tölt be. A szerzők a fetuin-A artériakalcifikációban és cardiovascularis betegségekben betöltött szerepét és prognosztikai értékét tekintik át, kitérve az ellentmondásosnak tűnő irodalmi eredmények magyarázatára és a lehetséges jövőbeni kutatási irányokra is.
