How Some People Can Never Get Infected With HIV/AIDS

HIV/AIDS 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.

Four 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.
