CD4 cells are infection-fighting white blood cells.
<h3>What are CD4 cells?</h3>
White blood cells called CD4 cells also referred to as T cells, are crucial components of your immune system because they combat infection. When a person has HIV, their CD4 count is used to determine how well their immune system is functioning (human immunodeficiency virus).
HIV not only attacks CD4 cells but also makes use of them to spread the infection. HIV uses the CD4 cells' capacity for viral replication to kill CD4 cells by producing more of the virus. The CD4 cells ultimately enlarge and explode as a result of this. HIV weakens the immune system by destroying CD4 cells.
