Question

Quizplus · Accepted Answer

CXCR4 and CCR5 proteins are cell surface proteins that act as co-receptors for HIV entry into host cells. Animals that lack these proteins, such as some strains of mice, are not susceptible to HIV infection. However, it is important to note that this does not necessarily mean that humans could be genetically engineered to lack these proteins as they play crucial roles in the immune system and trafficking of immune cells in the body.
