Treatment

Although there is no cure for HIV/AIDS, but there are things that can help control the virus. It is controlled by interrupting the reproduction of HIV. The virus in specifically attacks helper T-Cells.

Immune Cells

The immune cell involved is CCR5-delta32, mutation results in a smaller protein that is not on the outside of the cell anymore.

Replication

The virus replicates by first by the Lytic Cycle or begins with Lysogenic Cycle and ends with Lytic Cycle.


Steps in the Lytic Cycle


  1. Attaches to host cell.
  2. Entry into the cell.
  3. Synthesis of viral nucleic acid and proteins.
  4. Assembly
  5. Release

Steps in the Lysogenic Cycle


  1. Attaches to host cell.
  2. Entry into the cell .
  3. Phage DNA joins into bacterial chromosome.
  4. Bacteria reproduces, with the daughter cell.
