This may be debatable and/or depend on recent research. I want your opinion and evidence for that.
T cells are a type of white blood cell that play a critical role in the immune system. They are responsible for recognizing and attacking foreign invaders, such as viruses and bacteria, and also help regulate immune responses.
Antigen presenting cells are specialized immune cells that present foreign antigens to T cells. This process is essential for activating T cells and initiating an immune response against the specific antigen.
No, T cells are not considered antigen presenting cells. They do not have the ability to directly present antigens to other T cells, but they do rely on APCs to present antigens to them in order to become activated.
T cells play a crucial role in immunity by recognizing and attacking foreign invaders, as well as regulating immune responses. They can also differentiate into various types of T cells, such as helper T cells and cytotoxic T cells, to target specific threats.
T cells have specific receptors on their surface called T cell receptors (TCRs) that can recognize and bind to specific antigen fragments presented by APCs. This triggers a series of events that activate the T cell and initiate an immune response against the antigen.
