During a primary immune response to new pathogens or antigens, naive T cells are activated, and undergo proliferative expansion and differentiation into effector cells. Although most effector cells die after antigen clearance, some persist as memory T cells. The identity and functional properties of ...
Anyway, that’s why we call'em that—they come from the thymus. And T cells are a part of the body's immune system. They can recognize and eliminate cells from outside the body that might cause disease. FEMALE STUDENT: But why“ naive”? I mean, we might call people naive if they...
A cytotoxic T cell (CTL) is a type of T lymphocyte cell that is able to kill cancer cells, virus-infected cells, or other damaged cells that require elimination. From:International Journal of Biological Macromolecules,2021 Also in subject areas: ...

Turning to chimeric antigen receptor (CAR) T-cell therapy, “though promising, especially in B-cell lymphomas,” Barta said, “the approach does have its challenges in T-cell lymphomas, primarily because the antigens that are being targeted are also shared by normal T cells.” Cancer cells ...
come from studies in mouse models. Studies of Treg in humans are further complicated by the fact that the expression of Foxp3 and other surface markers of Treg can be transiently induced at low levels on conventional T cells upon stimulation of the T cell rec...
Programmed cell death (PCD) of T cells has been proposed to explain CD4 + T cell loss and impaired T cell function in HIV infection. Several laboratories have demonstrated that T cells from HIV-infected individuals indeed die upon cultu... L Meyaard,F Miedema - 《Current Topics in Microbio...
Most T cells only work in the person who made them. Your T cells fight threats by responding to molecular fragments that belong to a pathogen—but only when these molecules are bound with markers that come from your own tissues. Your influenza-fighting T cells can't help your neighbor, and...
T-cells are the immune system's security force. They seek out pathogens and rogue cells in the body and put them out of action. Their precursors are formed in the bone marrow and migrate from there into the thymus. Here, they mature and differentiate to perform a variety of tasks. Scient...
