What will happen if you lose all of your Tcells?​

This is why Killer T-cells are also called Cytotoxic T-cells. The pieces of destroyed cells and viruses are then cleaned up by macrophages. The other type of T-cell is the Helper T-cell. When a T-cell finds its virus match in your body, it makes many copies of itself to attack that virus.

answer:

there is no cure for hiv, although antiretroviral treatment can control the virus, meaning that people with hiv can live long and healthy lives. most research is looking for a functional cure where hiv is reduced to undetectable and harmless levels in the body permanently, but some residual virus may remain. most commonly hiv-antivirals are taken also known as nucleoside/nucleotide reverse transcriptase inhibitors (nrti's).

oh okay you then
