No, T cells do not express MHC II. MHC II molecules are primarily found on antigen-presenting cells, such as dendritic cells, macrophages, and B cells, and are involved in presenting antigens to T cells for immune responses. T cells, on the other hand, express MHC I molecules, which present antigens to other immune cells.
cells that replenish the lining of the gut
yes
No, NK cells are not CD3 positive. NK cells do not express the CD3 marker, which is typically found on T cells.
Muscle cells and liver cells have the same DNA, but they express different genes. This differential gene expression determines the unique characteristics and functions of each type of cell. Muscle cells express genes related to movement and contraction, while liver cells express genes related to metabolism and detoxification.
Yes they do. MHC 1 are expressed by all nucleated calls (except neurones) and platelets. MHC 11 are expressed by B-cells, macrophages and dendtitic cells. Therefore, some cells express both types.
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.
The symbol for iShares FTSE EPRA/NAREIT North America Index Fund in NASDAQ is: IFNA.
Cells that are part of a multi-cellular organism typically have the same metabolic functions as single-celled organisms, however differences exist. Multicellular cells will have a specialized function, typically do not have to independently gather food and will express target genes selectively rather than all of the genes necessary for survival that a single-celled organism might express.
All body cells have the same DNA. They all play different roles because the brain sends them signals to do so. You can't have them all doing the same thing. Ex: If you only have skin cells, then what cells will make up your heart or liver or bones?
