HIV/AIDS attacks the body by attaching itself to a target cell, then injecting genetic materials which force the cells to make duplicates of the virus.
There is a small population of people that are resistant to HIV/AIDS despite repeated exposure to the virus.
Below are the 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 resistant to HIV/AIDS have high Cytokines which help in reducing viral entry into host cells and decreases the replication of the R5 strain of HIV.
2. Strong immune system:
Some people’s immune systems 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 individuals carry this mutation in their CCR5 gene.
4. High cytotoxic T-lymphocytes:
Cytotoxic T-lymphocytes protect the body against HIV when there is consistent exposure to the virus.
