Question

Quizplus · Accepted Answer

People who are naturally resistant to HIV infection are believed to have a mutated allele of the CC-CKR5 gene. This mutation prevents the expression of the CC-CKR5 receptor, which is used by the HIV virus to enter T cells. Without this receptor, the virus cannot enter and infect the T cells, leading to the resistance to HIV infection. However, not all individuals who carry this mutation are completely immune to HIV, as some strains of the virus can use alternative receptors to enter T cells.
