HIV cripples the immune system by infecting and killing helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells. These cells hold crucial roles in the immune system in identifying and destroying antigens (foreign invaders). Over time, this destruction of the immune system causes the Acquired Immunodeficiency Syndrome (AIDS).

What is the immune disorder that occurs when the production or activity of immune cells or complement is abnormal?
The immune disorder that occurs when the production or activity of immune cells or complement is abnormal is called primary immunodeficiency. It is a group of genetic disorders that affect the immune system's ability to effectively defend the body against infections. This can lead to recurrent or severe infections and other immune-related complications.
What is an Immune suppressing drug?
Anything that reduces the activity of the immune system
How does methotrexate affect leukocytes in the body?
Methotrexate is an immunosuppressive medication that inhibits the proliferation of leukocytes, particularly lymphocytes, by interfering with DNA synthesis and cell division. It specifically targets rapidly dividing cells, which include both cancerous cells and immune cells. This reduction in leukocyte activity can help manage autoimmune conditions and certain cancers but may also increase the risk of infections due to decreased immune response. Overall, methotrexate alters the balance and function of the immune system by dampening leukocyte activity.
What is a immunostimulant?
Immunostimulants are substances that trigger increased immune activity. An example would be the compound called adjuvant that is found in most vaccines.
What cells suppress the immune response in order to prevent over activity?
Regulatory T cells (Tregs) are a type of immune cell that suppress the immune response to prevent overactivity. They play a crucial role in maintaining immune tolerance and preventing autoimmunity by controlling and regulating the activity of other immune cells.
What is Ampligen?
It a drug which stimulates the immune system and has antiviral activity
Does bortella pertussis produce exotoxin?
Yes, Bordetella pertussis produces an exotoxin called pertussis toxin. This toxin plays a key role in the pathogenesis of whooping cough by interfering with the host's immune response and contributing to the characteristic symptoms of the disease.
Why does a person with AIDS have a suppressed immune system?
The HIV virus attacks white blood cells, suppressing immune activity.
What is the Study of the immune system called?
Immunology is the study of the immune system.
What is involved in a variety of processes such as cell signaling immune response and enzyme activity?
proteins
What is involved in a variety process such as a cell signaling immune response and enzyme activity?
proteins
Which types of T cells are a critical component of the immune system because it stimulates and enhances the activity of other components of the immune system?
T -helper cells
