What else can I help you with?
What percentage of thymus cells contain DNA?
All cells contain DNA (even cells with no nuclei have mithcondria which encode their own genome). thymus cells have an especially high amount of DNA since they serve as a place where T cells mature.
Lymph node that contain t cells and b cells?
T-cells and B-cells are both initially made in the bone marrow. T-cells mature in the thymus. They both freely float around in all lymph nodes and the various lymph organs (e.g., tonsils, spleen...).
Do activated Tc cells only turn in to cytotoxic T-lymphocytes or do Tc differentiate into memory cells as well?
Activated Tc cells can differentiate into both cytotoxic T-lymphocytes, which directly kill infected or cancerous cells, and memory T cells, which are long-lived and provide a rapid response upon re-exposure to the same pathogen. This differentiation allows the immune system to mount a faster and more efficient response upon encountering the same threat in the future.
An immune response in which t cells destroy antigens?
This process is called cell-mediated immunity. T cells, specifically cytotoxic T cells, recognize and destroy cells that are infected with a pathogen or abnormal cells, such as cancer cells. This immune response is crucial for clearing infections and providing immunity against future exposures to the same antigen.
How do T-Cells fight infection?
Helper T cells activate killer T cells.
What percentage of thymus cells contain DNA?
All cells contain DNA (even cells with no nuclei have mithcondria which encode their own genome). thymus cells have an especially high amount of DNA since they serve as a place where T cells mature.
What is the structure of T lymphocytes?
T lymphocytes are characterized by a round or oval nucleus with a small amount of cytoplasm. They have cell surface receptors that can recognize specific antigens presented by antigen-presenting cells. T lymphocytes differentiate into various subsets such as helper T cells, cytotoxic T cells, regulatory T cells, and memory T cells.
Lymph node that contain t cells and b cells?
T-cells and B-cells are both initially made in the bone marrow. T-cells mature in the thymus. They both freely float around in all lymph nodes and the various lymph organs (e.g., tonsils, spleen...).
Where do t cells come from?
All T-cells originate in the same place in humans. They originate from hematopoietic stem cells which are located in the bone marrow.
Are plasma cells and helper t cells the same thing?
No, plasma cells and helper T cells are different types of immune cells. Plasma cells are a type of B cell that produces antibodies, while helper T cells are a type of T cell that helps activate other immune cells, including B cells.
How much persent of the blood consist of the solid part?
you have to count the amount of platilets and blood cells and white blood cells and T-cells
What does the medullary cords of a lymph node contain?
The medullary cords of a lymph node contain: reticular cells, lymphocytes, macrophages and plasma cells. It is important to understand that lymphocytes include both B cells and T cells. Note also that plasma cells derive from B cells. If asked a correct answer could be B cells and also plasma cells depending on the level of the material.
Which cells parts contain the most a t p?
Mitochondria are the organelles within cells that contain the highest concentration of ATP, which is the primary energy source for cellular processes. Mitochondria produce ATP through the process of cellular respiration.
Do activated Tc cells only turn in to cytotoxic T-lymphocytes or do Tc differentiate into memory cells as well?
Activated Tc cells can differentiate into both cytotoxic T-lymphocytes, which directly kill infected or cancerous cells, and memory T cells, which are long-lived and provide a rapid response upon re-exposure to the same pathogen. This differentiation allows the immune system to mount a faster and more efficient response upon encountering the same threat in the future.
What do T cells do What do b cells do?
t cells are killer cells b cells are antibodies
