In most solid tumours the largest immune population is not a T cell. It is a myeloid cell that has been recruited, expanded and re-educated by the tumour itself. Tumour-associated macrophages and mye

A T cell does not choose which tissue to defend. The tissue chose it, during priming. A naive T cell has no tropism at all; it acquires one from the dendritic cell that activates it, and the instruct

Signal 1 tells a T cell what it is looking at; signal 2 tells it whether to care. The same peptide–MHC engagement that launches a productive effector response can just as easily install an anergy pro

The neutrophil is the most heavily armed short-lived cell in the body. It leaves the marrow with its weapons already made — granules preloaded with elastase, myeloperoxidase and defensins — and spend

PI3K does not switch on a protein — it rewrites a membrane. Everything downstream follows from one chemical event: the 3-hydroxyl of a phosphoinositide is phosphorylated, PIP₂ becomes PIP₃, and every

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

In the periphery, co-stimulation rescues a T cell. In the thymus, the same molecules kill it. A peripheral T cell that engages its receptor without CD80 and CD86 becomes anergic; engage them and it r

Biomarkers · InflammationC-Reactive Protein (CRP): Structure, Function and Clinical UseCRP is the most widely measured marker of inflammation in medicine — fast to rise, fast to fall, and entirely non

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

Acute pancreatitis (AP) is a condition in which activated enzymes and inflammatory mediators released from the pancreas cause damage to the pancreas and surrounding tissues. AP is furt

Natural killer (NK) cells are a crucial component of the innate immune system and play a significant role in eliminating tumor cells. Unlike T cells, NK cells can recognize and kill cance

BDNF Overview Brain-derived neurotrophic factor (BDNF) is a central mediator of neuroplasticity, a term used to describe the ability of neurons
