In order to evaluate their ability to rescue autoimmune hepatitis (AIH) symptoms, the present work attempted to administer sMHCII molecules to an in vitro as well as in vivo concanavalin A (ConA)\u2010induced AIH model.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The in vitro AIH model consisted of splenocyte stimulation with ConA in the presence or absence of serum\u2010isolated sMHCII molecules. An in vivo ConA\u2010modified model with or without sMHCII treatment was developed. The cytokine profile in culture supernatants and serum was tested by ELISA. Cell markers were evaluated by immunofluorescence, while cell proliferation by tritiated thymidine uptake. AIH symptoms were assessed by daily observations for the establishment of a disease severity scoring system and liver histology was evaluated using a biomolecular imager.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The presence of sMHCII molecules in the ConA\u2010stimulated cell cultures leads to a significant reduction of cell proliferation. The administration of sMHCII molecules to the ConA\u2010treated animals showed a significant reduction in the levels of IL\u20102, IL\u20104, and IL\u201010, as well as a decrease in the number of spleen CD4<jats:sup>+<\/jats:sup> and CD8<jats:sup>+<\/jats:sup> cells. Upon development of a scoring system, it was shown that the sMHCII treatment was accompanied by a slower progression of the disease, while rescuing fibrotic liver morphology.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The results presented in this study confirm the ability of sMHCII proteins to alleviate autoimmune hepatitis,
