Interferons (IFNs) are a group of signalling proteins that are produced and released from cells in response to viral infection and other stimuli such as normal and tumour cell survival and

Cell Signalling · Kinase CascadesMAPK Signaling: The Pathway of Mitogen StimulationThe mitogen-activated protein kinase (MAPK) pathway is one of the most important signalling cascades in biology, conv

The T-cell receptor is the most finely calibrated detector in immunology. It must discriminate an agonist peptide present at a few dozen copies from a self peptide present at tens of thousands, and i

Cell Signalling · EnzymologyProtein Kinases: Function, Classification, Structure and InhibitorsProtein kinases transfer a phosphate group from ATP onto specific residues of target proteins, switching

HER2 has no ligand. HER3 has no kinase. Together they are the most potent signalling pair in human biology. That single sentence explains most of what is strange about this receptor family and all of

The ERK signal transduction pathway stands as a fundamental mechanism in cellular biology, orchestrating a wide array of physiological processes, including cell division, differentiation, and surv

A chimeric antigen receptor is a synthetic protein wired into a real signalling pathway. The extracellular half is an antibody fragment; everything below the membrane is borrowed from the T-cell rece
