HIV is the human immunodeficiency virus. Causer of AIDS, it attacks the immune system, responsible for defending the body from diseases. The most affected cells are CD4+ T lymphocytes. And it is by altering the DNA of that cell that HIV makes copies of itself.

<h3>1. Discuss the pathophysiology of HIV in relation to the reduction of CD4 cells</h3>

HIV binds to a component of that cell's membrane, CD4, penetrating its interior to multiply. As a result, the defense system gradually loses the ability to respond properly, making the body more vulnerable to disease.

<h3>2. Discuss the body's immune response to the virus (HIV)</h3>

The innate immune responses to HIV infection are mainly the intense production of cytokines, such as interleukin (IL)-1 and interferon (IFN)-1, and the activation of natural killer (NK) cells, which can temporarily control HIV replication. through apoptosis of infected cells

<h3>3. Explain the molecular and cellular immune response that leads to the swollen lesion.</h3>

due to the accumulation of primary immune cells and the body's long attempt to fight the infection

<h3>4. Discuss the cellular and molecular immune response that results in enlargement of the spleen and cervical lymph nodes</h3>

An infection from bacteria and viruses, including HIV, can cause swelling of the lymph nodes. The swelling occurs because the infection reaches the nodes through lymph fluid. HIV most often affects lymph nodes around the neck as well as in the armpits and groin.

Why are architects and engineers concerned about surface waves
Ainat [17]

Answer:

Because they are the most destruction waves

Explanation:

Surface waves travel just below the earth’s surface.  Examples of surface waves are Rayleighs and Long waves. Rayleighs cause ripples on the ground while long waves move the ground horizontally perpendicular to the direction of travel of the wave. Therefore, these waves are capable of destroying the foundations of structures and hence causing their collapse. Studying these waves allow these professionals to design foundations strong enough to withstand these waves.
