A Physician Is Attempting New Therapies for HIV Patients Who

question 87

Multiple Choice

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.
