What else can I help you with?
What t lymphocytes can kill invading organisms?
Cytotoxic
Are lymphocytes that directly kill virus- infected cells?
T cytotoxic cells
Which major class of lymphocytes become cytotoxic T cells?
CD8+ T lymphocytes, also known as cytotoxic T cells, become cytotoxic when they are activated by presenting antigens on major histocompatibility complex class I molecules. These cells play a key role in the immune response by directly killing infected or abnormal cells.
Which immune cells are attracted to the chemicals secreted by helper T cells?
Cytotoxic t cells and b lymphocytes!
What immune system cells are attracted to the chemicals secreted by helper T cells?
Cytotoxic t cells and b lymphocytes!
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.
Which type of white blood cells is produced in the thymus and destroys the cell membranes of bacteria?
The primary function of the thymus is the processing and maturation of special lymphocytes (white blood cells) called T-lymphocytes or T-cells, which are associated with antibody production. T-lymphocytes migrate from the bone marrow to the thymus, where they mature and differentiate until activated. in short the thymocytes present in the thymus produces the T lymphocytes
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.
T-lymphocytes are produced in?
T-lymphocytes are produced in the bone marrow from hematopoietic stem cells. They mature in the thymus, hence their name "T cells."
Which cell produces perforin?
Perforin is produced by cytotoxic T cells (CD8+ T cells) and natural killer (NK) cells. It is used in these cells to induce cell apoptosis in target cells, such as infected or cancerous cells.
Where are lymphocytes produced and stored?
The thymus is responsible for the t cell production.
What are lympthocytes?
Lymphocytes are types of White Blood Cells in the immune system. There are two main types of lymphocytes,B lymphocytes,T lymphocytes.Plasma B lymphocytes produce large amounts of antibodies when you have a bacteria, virus or fungi.Memory B lymphocytes remember things you've already had and change into Plasma B lymphocytes to then produce certain antibodies that can kill the bacteria before it turns into a disease.The T lymphocytes are much more aggressive though,things like cytotoxic T lymphocytes will destroy cells that are infected with a virus. Hope I helped. :)
