CD8 T Cell Killing Virally-Infected Cell - Immune System Defense Mechanism #2267140 (License: Personal Use)

This scientific illustration depicts the critical role of CD8+ T lymphocytes in cellular immunity: they identify infected cells via MHC-I presentation of viral peptides and induce apoptosis through perforin and granzyme release. The virally-infected cell is shown with internal viral particles (yellow dots), while the CD8 T cell engages at the surface, illustrating targeted immune clearance without harming healthy tissue.

Used in immunology education, medical textbooks, and health websites explaining antiviral immunity; matches user intent for understanding T-cell function, vaccine mechanisms, or autoimmune/infectious disease pathophysiology.
