Summary
Chimeric antigen receptor (CAR)-NK cell therapy enhances the immune system's natural killer (NK) cells to target virus-infected cells. This approach offers a promising strategy to overcome limitations of conventional antiviral treatments.
Area of Science:
- Immunology
- Virology
- Cell Therapy
Background:
- Viral infections cause significant global morbidity and mortality.
- Conventional therapies are limited by drug resistance.
- Natural killer (NK) cells are crucial for innate antiviral immunity.
Purpose of the Study:
- Review the role of NK cells in antiviral defense.
- Explore viral immune evasion mechanisms.
- Discuss advancements in Chimeric Antigen Receptor (CAR)-NK cell therapy for viral infections.
Main Methods:
- Review of existing literature on NK cells and viral infections.
- Analysis of viral immune evasion strategies.
- Examination of CAR-NK cell therapy optimization and applications.
Main Results:
- NK cells exhibit potent immunosurveillance and cytotoxic functions against viruses.
- Viruses employ diverse mechanisms to evade NK cell detection.
- CAR-NK cell therapy shows potential to enhance NK cell efficacy against infected cells.
Conclusions:
- CAR-NK cell therapy represents a promising strategy to enhance antiviral immunity.

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
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...

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
