T cell Activation does not drive CD4 decline in longitudinally followed HIV-infected Elite Controllers

<p>Abstract</p> <p>Background</p> <p>Elite controllers (EC) are a rare subset of HIV infected individuals who control viral load below 50 copies/ml of plasma without treatment.</p> <p>Methods</p> <p>Thirty four EC were studied. The slope of CD4 c...

The slope of CD4 count change was available for 25 of these subjects.
