A Physician Is Attempting New Therapies for HIV Patients Who

A physician is attempting new therapies for HIV patients who are suffering from an impaired immune response. He decides to try using a recombinant form of colony-stimulating factor cytokine (CSF) . Why?

A) CSF is a strong inducer of antiviral activities in our cells, and may help our immune system fight off the effects of an HIV infection for a longer period of time.
B) CSF will help to stimulate the production of new lymphocytes, the very cells that are affected by HIV. This may help to keep the patients' immune responses "normal" for a period of time.
C) CSF will hyperstimulate the activities of the macrophages, leading to aggressive ingestion and successful destruction of HIV-infected cells.
D) CSF will drive up the production of lactoferrin and transferrin, strong antiviral compounds produced in our mucus membrane secretions that trap and destroy viruses.
E) CSF is a cytokine that allows cells to communicate. If levels of CSF are elevated, HIV-infected cells can alert other healthy cells so that they produce protective IFNs.
