Killer T-Cell: The Immune System’s Elite Fighter Against Infection #2267128 (License: Personal Use)

This stylized illustration depicts a cytotoxic (killer) T-cell as an aggressive, anthropomorphized green immune cell with spiky protrusions, wearing red boxing gloves marked with skull-and-crossbones symbols. Its snarling expression and dynamic pose convey its mission: identifying and eliminating virus-infected or malignant cells through targeted destruction. The image simplifies complex immunology into an engaging, memorable visual metaphor for educational or medical outreach.

Used on health education websites, immunology infographics, vaccine campaign materials, or biology textbooks to explain adaptive immunity; matches user intent seeking accessible explanations of how the immune system fights disease.
