Immunohistochemical staining exposed a clear induction of vascular Icam1 expression following vaccination towards vimentin (Fig. 5a), in line using the effects of passive antibody treatment (Supplementary Fig. 4c). Though the total Icam1 mRNA expression showed only a small improve, probably on account of Icam1 expressionin non-ECs (Fig. 5b), mRNA expression of your blood vesselspecific adhesion molecule Vcam1 was markedly greater in tumors of vimentin-vaccinated mice (Fig. 5b). Concordantly, staining of B16F10 tumor sections of vimentin-vaccinated mice for Pd-l1 uncovered that vascular expression was reduced (Fig. 5c), as was supported by mRNA evaluation (Fig. 5d).
