4 reasons why some people cannot get infected with HIV/AIDS.

 

HIV attacks the body by attaching itself to a target cell, then injecting genetic materials which forces the cells to make duplicate of the virus. There are small population of people that are resistance to HIV/AIDS despite repeated exposure to the virus.

 

4 reasons why some people cannot get infected with HIV/AIDS.

1. High Cytokines: Cytokines are proteins that regulate the duration and intensity of immune response. Studies have shown that people who are resistance to HIV/AIDS have high Cytokines which help in reducing viral entry into host cells and decreases the replication of R5 strain of HIV.

2. Strong immune system: Some people’s immune system are strong enough to destroy the virus.

3. Mutation: A genetic mutation known as CCR5-delta 32 hampers HIV’s ability to infiltrate immune cells. A few individual carry this mutation in their CCR5 gene.

4. High cytotoxic T- lymphocytes: Cytotoxic T-lymphocyte protects the body against HIV when there is consistent exposure to the virus.
