The most abundant immunosuppressive molecule in a solid tumour is not a protein. It is adenosine — a metabolite, produced from ATP in two enzymatic steps, at concentrations orders of magnitude above

Interleukin 12 in COVID-19 Prophylactics Interleukin 12 is a cytokine with wide-reaching effects in the innate and adaptive immune system. Of

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

Introduction to TNFRSF9 and Its Role in Immune ActivationTNFRSF9, also known as 4-1BB or CD137, is a co-stimulatory receptor expressed on the surface of T cells, natural killer (NK) cells

Not one immune cytokine on this pathway touches bone. TNF, IL-1β, IL-6 and IL-17A all act on osteoblasts, osteocytes and synovial fibroblasts, and it is those stromal cells that decide between RANKL

CD155 is read by four different receptors, and only one of them turns the killing programme on. The nectin and nectin-like ligands induced on stressed and transformed cells are simultaneously an acti

Immunology · Cell BiologyCells of the Innate Immune System: Types, Functions and MarkersThe innate immune system responds within minutes, without prior exposure, using cells that recognise conserved m

The complex interplay between chemokines and cytokines is fundamental to the immune system's function, orchestrating the body's response to infection, inflammation, and injury. This detailed analy

Immunology · Innate ImmunityInnate Immunity: Components, Functions & First Line of DefenceThe innate immune system is the body’s first line of defence — a fast, non-specific response built from physic

PD-1 does not switch a T cell off; it moves the threshold. Engagement of PD-1 by PD-L1 recruits a single phosphatase into the immunological synapse, and that one recruitment event is enough to collap

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

Transplant rejection is the fastest, most violent adaptive immune response a body can mount — and it is a response to a molecule rather than to a pathogen. Somewhere between one and ten per cent of a
