1. T cell

   A T cell is a type of lymphocyte. T cells are one of the important white blood cells of the immune system and play a central role in the adaptive immune response. T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface. T cells are born from hematopoietic stem cells, found in the bone marrow. Developing T cells then migrate to the thymus gland to develop (or mature). T cells derive their name from the thymus. After migration to the thymus, the precursor cells mature into several distinct types of T cells. T cell differentiation also continues after they have left the thymus. Groups of specific, differentiated T cell subtypes have a variety of important functions in controlling and shaping the immune response. One of these functions is immune-mediated cell death, and it is carried out by two major subtypes: CD8+ "killer" (cytotoxic) and CD4+ "helper" T cells. (These are named for the presence of the cell surface proteins CD8 or CD4.) CD8+ T cells, also known as "killer T cells", are cytotoxic – this means that they are able to directly kill virus-infected cells, as well as cancer cells. CD8+ T cells are also able to use small signalling proteins, known as cytokines, to recruit other types of cells when mounting an immune response. A different population of T cells, the CD4+ T cells, function as "helper cells". Unlike CD8+ killer T cells, the CD4+ helper T (TH) cells function by further activating memory B cells and cytotoxic T cells, which leads to a larger immune response. The specific adaptive immune response regulated by the TH cell depends on its subtype (such as T-helper1, T-helper2, T-helper17, regulatory T-cell), which is distinguished by the types of cytokines they secrete.Regulatory T cells are yet another distinct population of T cells that provide the critical mechanism of tolerance, whereby immune cells are able to distinguish invading cells from "self". This prevents immune cells from inappropriately reacting against one's own cells, known as an "autoimmune" response. For this reason, these regulatory T cells have also been called "suppressor" T cells. These same regulatory T cells can also be co-opted by cancer cells to prevent the recognition of, and an immune response against, tumor cells.

1. t cell

   A T cell is a type of white blood cell that plays a crucial role in the immune system, particularly in the adaptive immune system. They are named after their place of maturation, the thymus. T cells have a variety of roles including killing infected host cells, activating other immune cells, producing cytokines, and regulating immune responses. They are also responsible for cellular immunity and assisting in the body's defense against pathogens and potentially malignant cells.

1. T cell

   T cells or T lymphocytes are a type of lymphocytes that play a central role in cell-mediated immunity. They can be distinguished from other lymphocytes, such as B cells and natural killer cells, by the presence of a T-cell receptor on the cell surface. They do not have antigen-presenting properties. They are called T cells because they mature in the thymus. There are several subsets of T cells, each with a distinct function.

Examples of T cell in a Sentence

1. Bob Carter:

   At Toyota, we believe that when good ideas are shared, great things can happen, the first generation hydrogen fuel cell vehicles, launched between 2015 and 2020, will be critical, requiring a concerted effort and unconventional collaboration between automakers, government regulators, academia and energy providers.

2. Jennifer Trilk:

   Mitochondrial function is important to almost every cell in the human body, so when you don't have mitochondrial function or when you have mitochondrial dysfunction, you have dysfunction of cells, so from a molecular standpoint, you start seeing cellular dysfunction years before you start seeing the global effect, which ends up coming out as symptoms of diseases: diabetes, cancers and cardiovascular disease.

3. Chris Collins:

   Is there anything to worry about ? The short answer is no, if people are not worried about current cell phone technology, they should be worried even less about 5G.

4. William Schaffner:

   I think what they're saying is virus number one initiates an inflammatory response which then acts as a barrier to the second virus, i think there are also some data to suggest Vanderbilt University's two viruses can not simultaneously infect the same cell.
