Signaling is fundamental to how cells sense and respond to their environment—but in immune cells, those signals must be ...

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 ...

Intracellular peptides, generated predominantly via the ubiquitin–proteasome system, have emerged as critical modulators of cell signalling. These peptides play multifaceted roles, ranging from ...

Cell signaling is crucial for cells to communicate and function correctly. Disruptions in these pathways, caused by genetic mutations or environmental factors, can lead to uncontrolled cell growth, ...
