Platelet activation plays a pivotal role in hemostasis, the process that stops bleeding and initiates wound healing. Central to this process is the activation of G protein-coupled receptors (GPCRs

Interleukin signaling is involved in a number of biological processes, including cell growth and differentiation, inflammation and immunity. Interleukins are glycoproteins which act on hema

Low-dose IL-2 expands regulatory T cells. High-dose IL-2 expands the cells they exist to restrain. Same cytokine, same receptor family, opposite clinical intent — and the explanation is a receptor su

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

Cell Signalling Cell signalling pathways have an important role in integrating a plethora of extracellular and intracellular signals to produce a controlled optimal o

Katherine Edwards, PhD Student, Queen’s University Belfast Cytokines play a vital role in immune responses enabling cross-talk between different cell types a

Cell Signalling · MetabolismInsulin Signalling & Receptor Tyrosine KinasesInsulin controls metabolism and growth through the insulin receptor — a receptor tyrosine kinase that branches into the

An agonist antibody does not activate its receptor. It gets held still by something else, and the receptors underneath cluster because they are crowded. That sentence sounds like a technicality and i

Chemokines are small signaling proteins that play a crucial role in the immune system by directing the movement of cells, orchestrating immune responses, and maintaining tissue homeostasis. The

Cell Signalling · CytokinesJAK-STAT Signalling: Mechanism, Regulation and InhibitorsJAK-STAT is the shortest route from a cytokine outside the cell to a change in gene transcription — receptor engagem

Almost all of the TGF-β in a tissue is already there, and almost none of it is active. That single fact reorganises how the pathway should be studied. Unlike most cytokines, TGF-β is deposited into t

The angiotensin pathway is a pivotal hormonal system that plays a crucial role in regulating blood pressure and maintaining fluid and electrolyte balance within the body. This complex biochemical

Phagocytosis is a subtraction, not a switch. A macrophage engulfs when its activating signals exceed its inhibitory ones, and every awkward result in the myeloid checkpoint field falls out of that on

Cell Signalling · Growth FactorsGrowth Factors: Families, Receptors and Signalling PathwaysGrowth factors are secreted proteins that instruct cells whether to divide, differentiate, migrate or survive
