HIV
The Human Immunodeficiency Virus (HIV) seems to only infect the CD4 (or T-helper) cells of the immune system. The CD4 cells are responsible for activating and directing other immune system cells. HIV also infects macrophages and microglial cells that express the CD4 molecule on their surface. The virus can also infect a subtype of myeloid dendritic cells MDC-1.
No, HIV primarily infects and targets cells of the immune system, specifically CD4 T cells. However, it can indirectly impact the nervous system by causing inflammation and affecting immune function, leading to HIV-associated neurological complications.
The immune system, specifically the innate immune system, works to destroy microorganisms that enter the body through the skin. Components such as phagocytes and natural killer cells help to identify and target these invaders for destruction.
HIV, the virus that leads to AIDS, infects cells by attaching to a protein on the surface of immune cells called CD4. Once attached, HIV then enters the cell, where it replicates and spreads to other cells. This leads to a weakening of the immune system, eventually progressing to AIDS.
Measles is a viral infection caused by the measles virus, which primarily infects and replicates in immune cells such as T lymphocytes and macrophages in the respiratory system.

The immune system identifies, remembers, attacks and destroys disease-causing invaders or infected cells.
HIV infects only the CD4 cells of the immune system, and it destroys lymphocytes.
No, HIV primarily infects and targets cells of the immune system, specifically CD4 T cells. However, it can indirectly impact the nervous system by causing inflammation and affecting immune function, leading to HIV-associated neurological complications.
HIV infects cells in the central nervous system and the immune system. HIV's main target cell is the T helper lymphocyte. These cells play a crucial role in the immune system, by coordinating the actions of other immune system cells. A large reduction in the number of T helper cells seriously weakens the immune system3
Type 1 diabetes
It attacks the cells in the immune system and simultaneously weakens or even destroys the whole system.
HIV attacks and destroys the immune system, specifically the white blood cells that fight infection.

When HIV enters a person's bloodstream, it targets and infects CD4 T cells, which are crucial for the immune system's function. The virus integrates its genetic material into the host cells, leading to the gradual depletion of these immune cells. This process weakens the immune system over time, making the individual more susceptible to infections and diseases. If untreated, HIV can progress to AIDS, where the immune system is severely compromised.
