The immune system of vertebrates is a powerful weapon against external pathogens and cancerous cells. T cells play a crucial role in this context. They carry a special receptor called the T-cell ...

T cells are our immune system’s customized tools for fighting infectious diseases and tumor cells. On their surface, these special white blood cells carry a receptor that recognizes antigens.

Sometimes a cell may need to toggle a receptor on and off, so there must be some other way of doing it. Araç's lab has been working for 11 years to reveal the structure of full-length aGPCRs, ...

By comparing an antigen-bound receptor image with that of an unbound receptor, the researchers could evaluate structural differences. The team utilized a T-cell receptor commonly used in immunotherapy ...

A T cell (pictured) can have many roles in the immune system. (Image courtesy NIAID) Scientists wouldn't normally expect to see a nuclear receptor such as RARα playing this role outside the cell ...

T cells are able to detect and respond to specific peptide antigens by virtue of the unique T cell receptor (TCR) complexes they express on their cell surface (see image). The TCR of conventional ...

Amino acids play a fundamental role in regulating how cells respond to drugs. These molecules, which form proteins, act like ...

G-protein-coupled receptors and their G protein partners are studied by single-molecule imaging in living cells, which reveals hot spots on the cell membrane where receptors and G proteins ...

During animal development, cells divide and arrange themselves in a coordinated way, eventually forming the embryo. The cells ...
