Which cells of the immune system are affected by HIV and leukemia and what parts of the immune response do these cells influence?
HIV primarily targets CD4+ T cells, which are crucial for orchestrating the immune response by helping activate B cells and cytotoxic T cells. In leukemia, particularly acute lymphoblastic leukemia (ALL), abnormal proliferation of lymphoid progenitor cells affects various immune cells, including B and T lymphocytes, leading to impaired immune function. Both conditions compromise the body's ability to mount effective immune responses, increasing susceptibility to infections and impacting overall immunity.

Leukemia is a cancer of the?
Leukemia is a cancer that affects the blood and bone marrow. It is characterized by the abnormal production of white blood cells, which are essential for the immune system. In leukemia, the bone marrow produces large numbers of abnormal white blood cells that do not function properly. These leukemia cells can crowd out normal blood cells, leading to problems with blood clotting, anemia, and a weakened immune system. There are different types of leukemia, and they are classified based on the type of white blood cell affected (lymphoid or myeloid) and whether the disease is acute or chronic. Acute leukemia progresses rapidly and requires immediate treatment, while chronic leukemia progresses more slowly and may not cause symptoms for many years. Common types of leukemia include acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), and chronic myeloid leukemia (CML). The specific type of leukemia and its classification influence the treatment approach and prognosis for individuals affected by the disease.
What parts of an immune response is directly affected by HIV and AIDS?
cd4 receptos
Which hormone helps the body control stress regulate metabolism and influence an immune response?
Ephinephrine
Is an allergy a circulatory system response?
No, an allergy is an immune system response to a substance that the body perceives as harmful. It is not directly related to the circulatory system, although allergic reactions can sometimes involve increased blood flow and inflammation in the affected area.
How is bone density affected by leukemia?
Leukemia is a type of cancer that usually starts in blood forming tissues (bone marrow) that makes the body inefficient in fighting with infections. Due to leukemia cancer body produces abnormal white blood cells that makes the immune system weak. It affects the bones adversely by reducing the density of bone and increasing the chances of fracture.
Which part of a specifics immune response?
Looking for antigens is part of a specific immune response.
Which is more rapid primary or secondary immune response?
Secondary Immune Response is more rapid.
What is the function of adjuvant in immune response?
When mixed with an immunogen, it enhances the immune response against the immunogen
How are antibodies and antigens related in the immune response?
Antibodies are proteins produced by the immune system in response to antigens, which are foreign substances that trigger an immune response. Antibodies bind to antigens to help neutralize or eliminate them from the body, playing a crucial role in the immune response.
What does the medical abbreviation FeLV mean?
FeLV stands for Feline Leukemia Virus, a retrovirus that causes leukemia in infected cats and undermines their immune systems.
How does stroke affect the immune system?
Stroke can significantly impact the immune system by triggering a systemic inflammatory response. This response can lead to the activation of immune cells and the release of pro-inflammatory cytokines, which may contribute to further brain injury and complications. Additionally, stroke can cause immune suppression, making the body more susceptible to infections, particularly in the respiratory and urinary tracts. Overall, the dual nature of the immune response following a stroke can complicate recovery and influence long-term outcomes.
What is an abnormal increase in WBC?
An abnormal increase in the number of WBCs can signal the sign of different conditions or issues in the body. These include infection, stress, inflammation or immune response to viruses or bacteria. It can also indicate the presence of leukemia.
