Question 10

How does HHV-8 infection in an HIV+ patient cause a malignancy like Kaposi's sarcoma?

Accepted Answer

A)   HHV-8 is a protovirus.
B)   HHV-8 converts normal cells to malignant cells recognized as foreign by a healthy person's immune system and destroyed. The compromised immune system of an HIV patient prevents this from happening and life-threatening Kaposi's sarcoma develops.
C)   HIV infection of the patient's TH cells enhances their activity, triggering the development of Kaposi's sarcoma by HHV-8.
