Abstract:
Memory CD8⁺ T cells play an essential role in controlling pathogenic infections. Therefore generating protective memory CD8⁺ T cells by vaccination is an attractive strategy for preventing and treating a variety of human diseases. Understanding what comprises a protective memory CD8⁺ T cell response will help optimize vaccine-induced CD8⁺ T cell immunity. Here we discuss essential antiviral effector functions and highlight how recall expansion of memory CD8⁺ T cells may affect the primary response.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
