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

What is Immunometabolism? Immunometabolism is an exponentially growing, multi-disciplinary field of research aiming at deciphering the dynamic cellular and mole

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

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

Immune Regulation in COVID-19: Immunomodulatory Mechanisms against SARS-CoV-2 Infection What is COVID-19?

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

Immunology · Myeloid CellsGranulocytes: Neutrophils, Eosinophils and BasophilsGranulocytes are the leukocytes with cytoplasmic granules and lobed nuclei — neutrophils, eosinophils and basophils. They

What is Wnt Signalling? The Wnt signalling pathway is an evolutionarily conserved pathway that plays critical roles in the regulation of determining cell fate, polari

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
