Infection with HIV can be prevented. Responsible decisions is the most valuable tool for protection against HIV.. Example: Abstinence from sexual activity and injecting drugs reduce your risk.. Chapter 4. Introduction. Molecules recognized as “non-self” are antigens. Several mechanisms to protect itself . First level of protection include physical and biochemical-skin, acid in stomach. Second level of protection phagocytic cells, enzymes, and proteins. The relationship between viruses and the immune system is much more intimate than it is for most bacteria: viruses often modify the cells within which they replicate, thereby rendering them ‘foreign’ and susceptible to attack by sensitized lymphocytes; furthermore, .
