Which of the following cell types are specific to a latent genital infection with HSV-2 ? (NOT RELATED)
**Core Concept**
Herpes Simplex Virus Type 2 (HSV-2) causes a latent genital infection, characterized by the presence of specific cell types in the affected area. This phenomenon is crucial for the virus's survival and reactivation mechanisms.
**Why the Correct Answer is Right**
During latent HSV-2 infection, the virus resides in the neurons of the dorsal root ganglia, specifically the sacral and lumbar ganglia. The infected neurons, known as **satellite cells**, surround the infected neurons and play a key role in the virus's survival and reactivation. These satellite cells are not present in the infected area during the acute phase of the infection.
**Why Each Wrong Option is Incorrect**
* **Option A:** T cells are involved in the immune response against HSV-2, but they are not specific to latent genital infection.
* **Option B:** Macrophages are also part of the immune response, but they are not specific to latent HSV-2 infection.
* **Option D:** Epithelial cells are the primary cells infected during the acute phase of HSV-2 infection, but they are not specific to latent infection.
**Clinical Pearl / High-Yield Fact**
During latent HSV-2 infection, the virus is not actively replicating, but the infected neurons are still expressing viral proteins, making them a potential target for antiviral therapy.
**Correct Answer:** C. Satellite cells.
