Which of the following cells are primarily targeted by HIV?
A
Nerve cells
B
Helper T cells
C
Phagocytes
D
Cytotoxic T cells
Explanation: 

Detailed explanation-1: -HIV primarily targets a type of cell in the immune system called the CD4+ T cell. However, many types of these cells exist, and they are not all equally susceptible to infection by HIV.

Detailed explanation-2: -HIV finds the white blood cells, called CD4 cells. HIV gets inside the CD4 cell and makes copies of itself. Then, HIV kills the CD4 cell and the new HIV copies find other CD4 cells to get inside and start the cycle again. HIV kills immune system cells that help the body fight infections and diseases.

Detailed explanation-3: -Role of CD4 T Cells in HIV Infection CD4 cells are the prime targets for this function in the course of an infection. During infection, HIV attaches to these helper cells, emptying its genetic material within so that the host’s genetic coding can be altered to produce other HIV virions (complete virus particles).
