Absence of B lymphocytes in CCM lesions in a sensitized murine model after B cell depletion. While CCM lesions harbored numerous brown stained CD45R/B220 positive B cells in untreated Pdcd10+/−Trp53−/− mice (left panel), lesions from the same murine model treated with anti-BR3 antibody contained no B cells (right panel). Scale bars are 50 μm
