Most immunology is written as though a T cell must first be told what to look for. Three lineages did not read that memo. γδ T cells, invariant NKT cells and MAIT cells leave the thymus with their ef

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

Introduction Tumorigenesis, the process by which normal cells transform into cancer cells, is a multifaceted and complex event influenced by various internal and external factors. Among the

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

An antibody's variable domains decide what it binds. Its Fc decides what happens next — and that is not a detail of formulation, it is half the mechanism. Which Fcγ receptor the constant region engag

A neuron is a cell that processes and transmits information through electrical and chemical signals. There are trillions of them in the human brain, which is able to carry out so many complex

The inflammasome is one of the few innate pathways that destroys the cell it activates. A macrophage that assembles NLRP3 has committed to a decision it cannot reverse: a priming signal through TLR4

Enzyme-Linked Immunosorbent Assay (ELISA) is a powerful analytical biochemistry assay that utilizes antibodies and color change to identify a substance. It is widely used in the field of immunolog

A T-cell engager does not give the T cell an instruction. It gives it an address. A bispecific antibody with one arm on CD3 and the other on a tumour antigen forces two membranes into contact and let

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

Immunology · Innate LymphocytesNatural Killer Cells: Receptors, Subsets and FunctionNK cells kill without prior sensitisation and without antigen-specific receptors, using a balance of activating and

A chemokine gradient does not move a leukocyte anywhere. It only tells one that has already stopped which way to go. That sentence is the whole map. Trafficking is a four-step cascade and the steps a

The antigen tells a CD4 T cell to respond; the cytokine tells it what kind of response to make. A naive CD4⁺ T cell leaving the thymus is uncommitted. Within about seventy-two hours of engaging TCR/C

Toll-like receptors are the reason a milligram of endotoxin can kill a mouse. They are the fastest, least discriminating layer of immunity: germline-encoded sensors that read conserved microbial chem
