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).
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.
Anything that reduces the activity of the immune system
Immunostimulants are substances that trigger increased immune activity. An example would be the compound called adjuvant that is found in most vaccines.
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.
It a drug which stimulates the immune system and has antiviral activity
The HIV virus attacks white blood cells, suppressing immune activity.
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.
