6-Sulpho LacNAc dendritic cells (SlanDC) express the histamine receptor H₄R on protein level. CD16 and H₄R expression on M-DC8-positive slanDC were measured by flow cytometry at day 0 and after 1 day in culture. In (a) one representative experiment of four which are summarized in (b and c) is shown. (white: isotype; grey: specific staining; the numbers given in the histograms are mean fluorescence intensity; relative expression levels of CD16 and H₄R were calculated as follows: specific staining times hundred divided by isotype staining).
