A cluster of recent studies has sharpened the scientific picture of how T cells switch on, tracking the molecular signals that launch immune responses with resolution measured in seconds. By combining ...

T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of the ...

The activation and regulation of T cells are fundamental to immune homeostasis and effective defence mechanisms. Ubiquitin ligases, such as c-Cbl and Cbl-b, serve as pivotal regulators by targeting ...

Efficient T-cell engineering is crucial for the success of CAR T-cell therapy research, but it requires multiple labor-intensive steps, including T-cell isolation, activation, and transduction.

Metabolism guides the activation states of regulatory T cells, the immune cells that prevent inappropriate activation of the immune system. St. Jude Children's Research Hospital scientists recently ...

Scientists have discovered that T cell receptors activate through a hidden spring-like motion that had never been seen before. This breakthrough may help explain why immunotherapy works for some ...

Lymph nodes, considered the command centers of our immune system, often get swollen and stiff when fighting infection. Now, a UC Berkeley-led team of researchers has discovered that this mechanical ...

A new immunotherapy drug has demonstrated early promise in a recent prostate cancer clinical trial. The drug, called VIR-5500, is a "masked T-cell engager." This type of immunotherapy ignites our own ...

For decades, cancer immunotherapy has focused primarily on CD8+ cytotoxic T lymphocytes as the main executors of tumor cell ...

CD8 + cytotoxic T lymphocytes (CTLs) serve as central effectors in cancer immunotherapy by directly eliminating tumor cells. However, current clinical therapies face significant limitations. These ...
