Question
Which are the antimicrobial substances in blood and tissues?
✓
Answer
- There are more than 30 serum proteins, circulating in the blood in an inactive state, which forms the complement system.
- ‘Complement cascade’ is activated by presence of pathogens and thus they eliminate pathogens.
- Cells which are affected by viruses secrete interferons which are a class of cytokines. These soluble proteins attack the pathogens.
- Some leucocytes stimulate other cells to protect themselves from viral infection.
