T cell

Small round to nearly spherical T lymphocyte in clean medical illustration style, with a smooth pale cell membrane, a large dense dark purple nucleus occupying most of the cell interior, and only a very thin rim or halo of pale blue cytoplasm. The cell is compact and visually similar to a B cell in overall size and shape, but lacks Y-shaped surface antibodies. The membrane may bear numerous short identical T-cell receptor proteins as small receptor-like projections or forked complexes embedded in the surface, creating a subtly irregular outline. No visible granules or other organelles are shown.
