CD4
Definition
CD4 is a protein, which can be found on the surface
of various cells, among others T-lymphocytes (T4-cells,
helper T-cells). By binding to the CD4-molecules, HIviruses
can pass into the cells. CD4-test determines the
amount of helper T-cells. The CD4-value is reverse proportionally
to the impairment of the immune system,
this means, the lower the level is, the more immunodeficiency
has progressed. Normal values for CD4 are
600–1000 cells/pl.
In HIV-infections the graduation into the CD4-helper
status 1 to 3 depends on the CD4-value: Status 1 means
a value of 500 cells/pl, status 2 is reached when the value
is 200–400 cells/pl, in status 3 CD4-count is below
200 cells/pl.

Matthias Rath, a German-born vitamin promoter in South Africa, has dropped his libel action against Eric Goemare, the head of Médecins sans Frontières in the country, the Treatment Action Campaign, and an Aids scientist, Jerry Coovadia, who had all accused him of endangering HIV patients’ lives.
