正确原文：Human immunodeficiency virus (HIV) inserts a DNA copy of itself into human immune cells during its lifecycle. Some newly infected immune cells can remain in a state of dormancy, known as the HIV latency period, for a long period of time. A new study published by American scientists in the Journal of Clinical Investigation has confirmed that microglial cells, a type of specialized immune cell in the brain that has a lifespan of up to 10 years, can serve as a stable reservoir of latent HIV. This study provides a new framework for efforts to eradicate HIV.
