Db-gp33-specific CD8 T cells are cytotoxic CD8 T-cells which can specifically recognize the gp33 epitope when presented in the context of the mouse MHC class I complex, H-2Db. The gp33 epitope is comprised of the sequence of amino acids in positions 33-41 of the glycoprotein from LCMV (Lymphocytic Choriomeningitis Virus).

Which major class of lymphocytes become cytotoxic T cells?
CD8 cells become cytotoxic T cells.
What is the difference between T-cells and killer T-cells?
Cytotoxic T-cells are just a specialized subset of T-cells that express CD8 (a co-stimulatory molecule). In general, there are two types of T-cells, helper T-cells that express CD4 and cytotoxic T-cells that express CD8. As the name implies, cytotoxic T-cells have the role of killing any infected cells.
What is meant CD8 or cytotoxic T cells?
A cytotoxic T-cell is a form of lymphocyte that is the "killer" T-cell. This cell engulfs damaged or viral/bacterial cells to stop them from infecting the blood.
What are the 3types of t cells?
Cytotoxic CD8 T cell Helper (Th1) CD 4 T cell Helper (Th2) CD 4 T cell
How many cells are in white blood cells?
There are seven (7) main types of white blood cells. These are the Neutrophil, Eosinophil, Basophil, Lymphocyte, Monocyte, Macrophage, and Dendritic cells.-Neutrophils- Target bacterial and fungal pathogens.-Eosinophils- Target larger parasites and modulate allergic inflammatory response-Basophils- Release histamines for inflammatory response-Lymphocytes- There are three (3) subtypes of lymphocytes:-B Cells- Release Antibodies and assist activation of T Cells-T Cells-Th (Helper) T Cells- Activate and regulate T and B cells-CD8+ Cytotoxic T Cells- Target virus infected and tumor cells -Gamma Delta T Cells (γδ T cells)- Help modulate adaptive immunity-Suppressor T Cells- Returns immune system to regular state after destruction of pathogen-Natural Killer Cells- Target virus infected and tumorous cells in conjunction with CD8+ Cells-Monocytes- Divide into Macrophages and Dendritic Cells and serve as a carrier of Macrophages and Dendritic Cells to site of immune activity.-Macrophages- Phagocytosis (Cell Eating or Consumption) of foreign particles such as debris or pathogenic agents. They also stimulate lymphocytes to respond to a pathogen.-Dendritic Cells- Activate T-Lymphocytes
Which major class of lymphocytes become cytotoxic T cells?
CD8 cells become cytotoxic T cells.
Are cytotoxic T cells a type of T cell clone?
Yes, cytotoxic T-cells are a subset of T-cells that in contrast to helpter T-cells express CD8.
How are cytotoxic T lymphocytes produced?
CD8+ T cells divide and differentiate into cytotoxic T lymphocytes.

What does T in T cells stand for?
The T in T-cells stands for the thymus gland. Lymphocytes produced in the bone marrow are either become B-cells or they are matured in the thymus gland and are "trained" to be either Natural Killer T-cells, CD4 (Helper T-cells), CD8 (Suppressor T-cells).

Cytotoxic CD8 T cell Helper (Th1) CD 4 T cell Helper (Th2) CD 4 T cell
Suppressor T cells are associated with?
T-suppressor cells: T cells that express the CD8 transmembrane glycoprotein (CD8+ T cells). They close down the immune response after invading organisms are destroyed. Suppressor T cells are sensitive to high concentrations of circulating lymphokine hormones, and release their own lymphokines after an immune response has achieved its goal. This signals all other immune-system participants to cease their attack. Some memory B-cells remain after this signal to ward off a repeat attack by the invading organism. Also known as T-8 cells.
How do the helper T cells first become part of the immune response to invasion by a virus?
T helper cells (CD4 T cells) serve to guide the development of adaptive (acquired) immune responses. Once they are activated and instructed by cells of the innate (natural) immune system, they "help" to activate cytotoxic (CD8) T cells and B cells (antibody producers). In the case of viruses T helper cells, once polarized, will produce signaling molecules (such as IL-2) that alert the CD8 T cells to the infection and will help activate B cells and will instruct them as to which flavor or antibody is best to produce. The CD4 T cells will also release other signaling proteins (such as Interferons) that help get rid of the virus.

When an antigen binds to a Class 1 MHC molecule it stimulates what cell?
Class I MHC molecules present antigens to cytotoxic T-cells (which are CD3+CD8+).
How many types of Non-Hodgkin Lymphoma are there?
There are at least 10 types of non-Hodgkin's lymphomas.
