For survival reasons or otherwise, the immune system would save a "file" of certain intruders and threats based on traits and characteristics. The protein, called Lck, is what "teaches" T-cells (white blood cells that attack viruses and other threats) to identify the characteristics of pathogens, whether clearly or vaguely identified within the body. As a result, Lck helps prevent the body's immune system from being constantly weighed down by a "biological hard drive" remembering all cell and invader statuses.

Oh yes. Your immune system is what fights infections and with out your immune system you will get all kinds of infection and it can be fatal.
That would be the immune system
When someone has AIDS there adaptive immunity (the immunity that remembers previous infections) is severely compromised. The adaptive immunity is responsible for remembering previous infections and dealing with them. Since the immune system is so weak and has a bad memory of previous infections it takes a much longer time for your body to defend against new pathogens along with previous pathogens that your body currently has and is no longer able to manage.
Because the HIV virus weakens the immune system of the body.
This system is the immune system.
The immune system fights HIV by killing the opportunistic infections.
Your immune system cant produce antibodies for infections/viruses if it is not exposed to them.
To fight off infections.
The immune system.
Yes
When the immune system is compromised, it is known as an immunodeficiency. This condition can result from various factors, including genetic defects, certain medical treatments, or infections like HIV/AIDS. Individuals with immunodeficiency are more susceptible to infections and may have difficulty fighting off diseases that a healthy immune system would typically manage. Treatment often focuses on managing infections and supporting the immune system.
