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

Quick answer A researcher running a Rat Eotaxin/CCL11 (Eotaxin) sandwich ELISA saw sample readings sit above the top standard and wells turn colour the instant TMB was added — even aft

NF-κB is not one pathway, it is two clocks running at different speeds. The canonical arm fires within minutes of TNF-α, IL-1β or LPS reaching the surface, peaks, and is switched off by feedback it e

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

Quick answer A researcher's colorimetric adenosine assay looked broken — the standard curve came out with a negative slope and the calculated values made no sense. The assay itself wa

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

Two drugs aimed at the same axis can give opposite results in the same disease. Blocking IL-23p19 is highly effective in psoriasis and works in Crohn’s disease. Blocking IL-17A directly is highly eff

For decades, the brain has been considered an immune sanctuary, protected by the formidable blood-brain barrier. This intricate defense system, while vital for safeguarding our most complex organ, ha

Double-stranded DNA in the cytosol is always a mistake. A virus has uncoated, a mitochondrion has ruptured, a micronucleus has burst, or a chromosome has been broken and left unrepaired. cGAS treats

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

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

CXCL16 CXCL16, a unique member of the CXC chemokine family, stands at the crossroads of immune modulation and vascular biology. Initially discovered as a chem
