Hello and thanks for your post.
There are several different types of T (or Thymus-derived) cells. Most T cells are either CD4 or CD8's-- otherwise known as T-helper and T-suppressor cells. HIV infects cells that express the CD4 cell surface protein.
For more information on the immune system and T cells, here's a link to an article on the subject on TheBody.com.
