How CANCER CELLS Hide From Your IMMUNE SYSTEM
Some tumor cells use PD-L1 to engage PD-1 on T cells and dampen their response. This is one immune-evasion example. Target recognition and inhibitory signaling are different interactions.

What the illustration shows
Portrait medical poster titled “How CANCER CELLS Hide From Your IMMUNE SYSTEM.” A prominent subtitle bounds this to one example: PD-L1 on some tumor cells can dampen a T-cell response. At top, a peach illustrative tumor cell on the left and a blue T cell on the right have separate membranes and separate nuclei. A small framed contact is enlarged below. In the magnified interface, the tumor-cell membrane is at left and the T-cell membrane at right. The upper contact is target recognition: membrane-anchored peptide–MHC I on the tumor side meets a T-cell receptor on the T-cell side. A separate lower inhibitory contact shows PD-L1 anchored on the tumor side binding PD-1 anchored on the T-cell side. A cyan arrow points into the T-cell side toward the label “Reduced T-cell response.” Notes explain that recognition and inhibition differ, not all tumors use the same escape mechanism, and “Hide” is a metaphor rather than intention or invisibility. Molecular shapes are explicitly simplified and not to scale. Gold AllHumanBody.com branding and the complete slogan are on a plain navy footer.
How to interpret this poster
- “Hide” is metaphor, not intention, invisibility or inevitable failed recognition. Shapes/counts not measured molecular structures or expression. No immunotherapy recommendation, efficacy, prognosis or patient selection.
- AI-assisted educational illustration; not physician certification, a diagnosis or individualized medical advice.
- Fine annotations require enlargement; preserve the full uncropped illustration and its qualifiers.
