The discovery of inhibitor of apoptosis (IAP) genes in baculoviruses over 20 years ago revolutionized understanding of apoptosis regulation. This review details viral IAP functions and their impact on cellular processes.
Area of Science:
- Molecular Biology
- Virology
- Cell Biology
Background:
- The discovery of the first inhibitor of apoptosis (IAP) genes in baculoviruses marked a significant milestone.
- Over 200 viral IAP homologs are now identified across various invertebrate DNA viruses.
Observation:
- Viral IAPs play crucial roles in regulating apoptosis.
- These proteins may also influence other cellular processes beyond apoptosis.
Findings:
- This review traces the historical discovery of viral IAP genes.
- It synthesizes current knowledge on diverse viral IAP types and their specific functions.
Implications:
- Understanding viral IAPs offers insights into fundamental biological processes.
- This knowledge has implications for both insect and mammalian cell biology and disease research.

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...
