During the elimination phase, immune effector cells such as natural killer cells, with the help of dendritic and CD4+ T-cells, are able to recognize and eliminate tumor cells (left). As a result of heterogeneity, however, tumor cells which are less immunogenic are able to escape immunosurveillance (right).
T cells' functional capacity is most influenced by aging effects. Age-related alterations are evident in all T-cell development stages, making them a significant factor in immunosenescence. [27] T-cell function decline begins with the progressive involution of the thymus, which is the organ essential
In cell biology, a lymphokine-activated killer cell (also known as a LAK cell) is a white blood cell, consisting mostly of natural killer, natural killer T, and T cells that has been stimulated to kill tumor cells, but because of the function in which they activate, and the cells they can successfully target, they are classified as different than the classical natural killer and T lymphocyte ...
Immune cells such as T-cells are usually isolated from patients for expansion or engineering purposes and reinfused back into patients to fight diseases using their own immune system. A major application of cellular adoptive therapy is cancer treatment, as the immune system plays a vital role in the development and growth of cancer. [ 1 ]
The diagram above represents the process of chimeric antigen receptor T-cell therapy (CAR), this is a method of immunotherapy, which is a growing practice in the treatment of cancer. The final result should be a production of equipped T-cells that can recognize and fight the infected cancer cells in the body.
Longitudinal studies on T SCM dynamics in patients undergoing hematopoietic stem cell transplantation (HSCT) have shown that donor-derived T SCM cells were highly enriched early after HSCT, differentiated directly from Tn, and that Tn and T SCM cells (but not central memory or effector T cells) were able to reconstitute the entire heterogeneity of memory T cell subsets including T SCM cells.

Possible senolytic agents are under preliminary research, including some which are in early-stage human trials. [6] [7] [clarification needed] The majority of candidate senolytic compounds are repurposed anti-cancer molecules, such as the chemotherapeutic drug dasatinib and the experimental small molecule navitoclax.
The premise of CAR-T immunotherapy is to modify T cells to recognize cancer cells in order to target and destroy them. Scientists harvest T cells from people, genetically alter them to add a chimeric antigen receptor (CAR) that specifically recognizes cancer cells, then infuse the resulting CAR-T cells into patients to attack their tumors.
