The IgSF protein expression profiles in the HaemAtlas. The expression patterns of cell-specific IgSF family members (columns) together with those expressed across several cell types (rows) are depicted, with yellow boxes indicating cells in which genes are expressed. For example, CD8⁺ T cells are the only cell type to express CD8B, whereas FcRLB and LAIR1 are expressed in NK and B cells. The size of the font and the green-to-red color intensity are both indicative of the strength of mean expression across the cells.
