Immunohistochemical staining unveiled a clear induction of vascular Icam1 expression following vaccination towards vimentin (Fig. 5a), in line with the effects of passive antibody treatment (Supplementary Fig. 4c). While the complete Icam1 mRNA expression showed only a small increase, almost certainly as a result of Icam1 expressionin non-ECs (Fig. 5b), mRNA expression of your blood vesselspecific adhesion molecule Vcam1 was markedly enhanced in tumors of vimentin-vaccinated mice (Fig. 5b). Concordantly, staining of B16F10 tumor sections of vimentin-vaccinated mice for Pd-l1 unveiled that vascular expression was lowered (Fig. 5c), as was supported by mRNA examination (Fig. 5d).
