@moesabimi: HIV infects and destroys LT4 cells, weakening the immune system #Science #system 1️⃣ Attachment and Entry The virus binds to CD4 receptors on the surface of LT4 lymphocytes, then enters the cell. 2️⃣ Genetic Material Conversion The viral genetic material (RNA) is converted into DNA using a special enzyme called reverse transcriptase. 3️⃣ Integration into the Nucleus The viral DNA integrates into the cell’s DNA, becoming part of it. 4️⃣ Replication Inside the Cell The infected cell starts producing new viruses instead of performing its immune functions. 5️⃣ Cell Destruction When new viruses are released, the LT4 cell dies or gradually becomes damaged.
