How actin aids T cell action

Researchers have discovered that actin forms wavefronts around the synapse centre, actively transporting TCR microclusters towards the cell edge. This process rescues TCRs from endocytosis and enables T cells to bind to multiple APCs in succession.

T-Cell: Unlocking immunity with new insights into activation

Researchers at the Hebrew University of Jerusalem developed a Bayesian metamodeling technique to analyze T-cell activation, revealing intricate patterns in early signaling. The study sheds light on the molecular processes behind T-cell activation and has implications for improving treatments for various diseases.

T cells use force to destroy cancer cells

Researchers at UNSW Sydney discovered that T cells use mechanical forces to propel lytic granules towards cancer cell membranes. The study found that the shape of the target membrane plays a crucial role in T cell-mediated cancer cell killing, with a bias towards outwardly curved membranes.

Researchers solve the mystery of a key structure in immune system cells

Researchers identified a bull's eye-shaped structure between white blood cells that enhances sensitivity to antigens but cuts off signaling beyond a threshold, preventing T-cell death. This adaptive control device enables the immune system to respond to signs of infection over a wide range of magnitudes.
