CD4+ T cells are central to the immune system, functioning as coordinators of immune responses and regulators of immune tolerance. These cells are divided into two primary subtypes: Helpe

1. What is a Biosimilar? A biosimilar is a biologic medical product that is highly similar to an already-approved reference biologic. While minor differences in clinically inactive compon

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

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

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

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

Toll-Like Receptors The innate immune response has come under the spotlight in recent years due to its central role in propagating the pathogen

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
