Question

Future treatment for disease, such as HIV, involves

A) the removal of receptor proteins from the cell membrane
B) blocking recognition proteins on the HIV virus
C) blocking receptor proteins in the cell membrane
D) adding recognition proteins to the cell membrane

Answer 1

Future treatments for HIV focus on blocking receptor proteins in the cell membrane to prevent the virus from entering and replicating within host T cells.

Step-by-step explanation:

Future treatments for diseases such as HIV involve blocking receptor proteins in the cell membrane (option C). HIV targets T cells by binding to the CD4 receptor on the surface of these cells and then uses the cell's machinery to replicate.

Current treatments for HIV aim to target the virus itself while sparing human cells, using drugs that inhibit viral entry, replication, or the function of virally encoded enzymes that are necessary for the virus to multiply but are not found in normal human cells. One class of such drugs inhibits the HIV virus from entering T cells, effectively blocking the virus's ability to infect and replicate within the host cells.
