Cathelicidin is expressed in NK1.1⁺ and NKp46⁺ cells in the B16 tumor microenvironment. Immunofluorescence staining was performed on paraffin-enbedded sections from B16 tumor-bearing mice for mCRAMP (green), NK1.1 (red), and DAPI (blue). mCRAMP is present in the tumor microenvironment and colocalizes with NK1.1⁺ (AC). mCRAMP expression also colocalized with NKp46⁺ (D and E). The majority of cells that migrated to the B16 tumor were NKp46⁺ but CD3⁻ (F and G). Scale bar: 10 μm.
