HIV replication cycle, diagram
HIV replication cycle. Diagram and magnified views showing the retroviral process by which the human immunodeficiency virus (HIV) replicates. Incoming virus particles (far left) attach to cell receptors (view 1) and release their protein core through the cell membrane. The core releases the RNA (ribonucleic acid) which is converted to DNA (deoxyribonucleic acid) by an enzyme (view 2). The viral DNA enters the nucleus (centre) and is added to the cells DNA (view 3) and used to make new RNA (view 4) that leaves the nucleus and directs ribosomes to make new viral proteins (view 5). These make new virus particles (far right, views 6 and 7)

EDITORS COMMENTS
This print showcases the intricate process of HIV replication, providing a detailed diagram and magnified views that unravel the retroviral journey of the human immunodeficiency virus (HIV). At first glance, incoming virus particles can be seen attaching to cell receptors in view 1, followed by their protein core being released through the cell membrane. In view 2, an enzyme converts RNA (ribonucleic acid) into DNA (deoxyribonucleic acid), which then enters the nucleus at the center of the image. View 3 reveals a crucial step as viral DNA merges with the host cell's own DNA, becoming integrated within it. This integration allows for new RNA synthesis in view 4, which subsequently exits the nucleus and directs ribosomes to produce new viral proteins in view 5. These proteins play a pivotal role in generating fresh virus particles depicted on far right views 6 and 7. The remarkable artwork not only highlights this complex replication cycle but also emphasizes its significance within biology and medicine. It serves as a visual representation of how HIV infects cells, replicates itself using cellular machinery, and ultimately leads to acquired immune deficiency syndrome (AIDS). This scientifically accurate illustration provides valuable insights into virology and molecular biology while shedding light on critical aspects such as biochemistry and cell biology. With its meticulous attention to detail and comprehensive depiction of each stage involved in HIV replication, this print from Science Photo Library is an invaluable resource for researchers studying this devastating disease.
