HIV particles in infected cell, TEM
HIV particles. Coloured transmission electron micrograph (TEM) of human immunodeficiency virus (HIV) particles (orange) in a host cell. HIV causes the disease AIDS. The virus attacks CD4+ T- lymphocytes (pink), white blood cells that are a crucial part of the bodys immune system. It enters the cell and hijacks the cells machinery to copy itself. The cell dies when the virus clones burst from it, which weakens the immune system, making the AIDS patient susceptible to otherwise harmless secondary infections.

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate world of HIV particles within an infected cell. In this coloured transmission electron micrograph (TEM), we witness the orange HIV particles invading a host cell, highlighting the destructive nature of this virus that causes AIDS. The image beautifully illustrates how HIV targets CD4+ T-lymphocytes, crucial white blood cells responsible for our immune system's defense. Upon entry into the cell, HIV hijacks its machinery to replicate itself relentlessly. Eventually, as these virus clones burst forth from their host, they cause the death of the cell itself. This process weakens the immune system and renders AIDS patients vulnerable to otherwise harmless secondary infections. With a magnification of 48,000x when printed at 10 centimeters across, every detail is brought to life in this micrograph. The inset in the bottom right corner provides an even more astonishing view at 161,000x magnification. This image not only serves as a testament to scientific advancements but also acts as a stark reminder of the ongoing battle against infectious diseases like HIV/AIDS. It underscores both the complexity and fragility of our biological systems while emphasizing why continued research and medical interventions are essential in combating such pathogens.
