What else can I help you with?
What is the name of an inappropriate immune response?
Autoimmunity or hypersensitivity.
What has the author Guido Kroemer written?
Guido Kroemer has written: 'Mechanisms of immunological self-tolerance' -- subject(s): Immunology, T-Lymphocytes, Autoimmunity, Immunological tolerance, B-Lymphocytes, Immune Tolerance
How is sympatric similar to allopatric speciation?
They both are mechanisms by which new species arise grad point
Condition whereby low level of autoimmunity can be beneficial?
A low level of Autoimmunity is beneficial, period. High autoimmunity means a person is allergic to himself or herself. The immune system begins to destroy the person it should protect. It is thought to cause arthritis, diabetes, and a host of other diseases.
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.
Does it mean you have an auto immune disease if you have had a positive ana test?
A positive ANA test does not necessarily mean the patient has an autoimmune disease. An ANA test is not specific for autoimmunity, but is a sign of inflammation that is often specific to autoimmunity. Specific antibodies are usually tested for to determine if a patient has an autoimmune disease.
What is the condition in which the immume system mistakenly attacks the thyroid?
When the immune system mistakenly attacks a normal part of the body, this is known as autoimmunity. Autoimmunity that causes hypOthyroidism (low thyroid) is called Hashimoto's Thyroiditis. This condition can also cause hypERthyroidism as well. There are specific antibodies in patients with Hashimoto's. Autoimmunity that causes hypERthyroidism is usually a condition known as Graves' Disease. There are specific antibodies in patients with Graves' Disease.
How are regulatory T cells activated and what role do they play in the immune response?
Regulatory T cells are activated by recognizing specific antigens presented by other immune cells. Once activated, they suppress excessive immune responses to prevent autoimmunity and maintain immune tolerance. They play a crucial role in controlling inflammation and preventing immune reactions against self-tissues.
If cd4 is high in blood will this affect implantation of embryos?
CD4 T cells are a type of white blood or immune cell. Elevated levels suggest an immune response is underway. Most likely this is due to a mild infection but could also indicate autoimmunity (immune reaction against yourself).
How is sympatric speciation similar allopatric speciation?
They both are mechanisms by which new species arise
Does aids stand for autoImmunodeficiency Syndrome?
AIDS stands for Acquired Immune Deficiency. It is caused by a virus. It is not autoimmune. They are they exact opposite. In autoimmunity, the immune system is over active and mistakenly attacks the healthy self. In AIDS the immune system is extremely weakened and attacks next to nothing.
What role do cytokines, proteins that regulate immune responses, play in the body's defense mechanisms?
Cytokines are proteins that help regulate the immune system by signaling between cells. They play a crucial role in coordinating the body's defense mechanisms, such as inflammation and immune responses, to fight off infections and diseases.
