T Cell Receptors

Discovering the first steps in transcription-coupled repair

Scientists have discovered the roles of two proteins in recognizing blockages in transcription and initiating efficient repair. Their results suggest a previously unsuspected mechanism for the repair process, shedding light on Cockayne Syndrome, a fatal form of accelerated aging.

How do you spell recognition? C-O-R-E-C-E-P-T-O-R

Researchers describe the interaction between T-cell receptors and coreceptors during an immune response. They found that T-cell receptors and CD8 coreceptors are brought together during antigen sensing, increasing their interaction with endogenous non-stimulatory peptides.

Fox Chase study shows that weakened T-cell receptor signals change T-cell lineage

Weakened T-cell receptor signals shift T-cell lineage towards the gamma-delta pathway, enabling immune surveillance against external disease-causing agents. Gamma-delta T cells appear particularly adept at combating skin cancers and may play a role in detecting potential cancers.

Researchers Engineer A Way To Improve T-Cell Receptors

University of Illinois scientists developed a method to improve T-cell receptor properties, allowing for manipulation of the immune system's recognition molecules. This breakthrough could lead to new therapeutic approaches for diseases such as AIDS, cancer, and multiple sclerosis.
