In most solid tumours the largest immune population is not a T cell. It is a myeloid cell that has been recruited, expanded and re-educated by the tumour itself. Tumour-associated macrophages and mye

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

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

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

Introduction Discover the multifaceted role of CD33, a critical player in immune function and disease, shaping our approach to treating cancers and neurodegenerative conditions

Understanding Lag-3, Tim-3, and TIGIT: Key Players in T Cell RegulationThe immune system's ability to regulate T cell responses is crucial for maintaining homeostasis and combating diseases such as ca

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

Antigen's are foreign molecules recognised by the immune system. Antigens can be protein, carbohydrate, lipid or nucleic acid molecules. Examples include viruses and bacteria as well as fr

Imagine a world where cancer treatment is no longer a blunt instrument but a precision-guided surgical strike, executed by the body's own immune system. For years, we have dreamed of 'smart' cells th

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

Natural killer (NK) cells are a crucial component of the innate immune system and play a significant role in eliminating tumor cells. Unlike T cells, NK cells can recognize and kill cance

If your knockout showed a type 2 phenotype and you attributed it to Th2 cells, there is a reasonable chance you were looking at something else. Innate lymphoid cells run T-bet, GATA3 and RORγt — not

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
