Verified step by step guidance1
Understand that HIV primarily targets cells with CD4 receptors, which are crucial for the immune response.
Recognize that helper T cells, also known as CD4+ T cells, are the main targets of HIV due to their CD4 receptors.
Identify that macrophages, which are a type of white blood cell involved in detecting and destroying pathogens, also express CD4 receptors and can be infected by HIV.
Acknowledge that HIV can cross the blood-brain barrier and infect brain cells, particularly microglial cells, which are the resident immune cells of the central nervous system.
Conclude that besides helper T cells, HIV can infect macrophages and brain cells, making them two other types of cells susceptible to HIV infection.
