Cell Signalling · InflammationMAPK Signalling in Inflammatory Cytokine PathwaysMAPK cascades convert receptor engagement into changes in gene expression, and in inflammation they do it in both directi

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

The germinal centre is where antibody quality is made. A naive B cell that binds antigen does not become a source of protective, high-affinity IgG by accident. It passes through a tightly choreograph

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

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

What is a Macrophage? Macrophages are indeed a type of phagocyte, responsible for engulfing and destroying foreign particles and cellular debris. They are larger cells with more cytoplasm an

Blocking TNF cures rheumatoid arthritis in some patients and triggers demyelination in others. That is not a dosing problem, and it is not a patient-selection problem. It is the direct consequence of

Quick answer A researcher preparing a Human IL-18 ELISA wasn't sure whether the protocol's “300-fold” HRP-Streptavidin step meant adding 40 µL of concentrat

V-domain Ig suppressor of T cell activation (VISTA) is an emerging immune checkpoint receptor that plays a key role in suppressing T cell activity within the tumor microenvironment (TME).

Toll-like receptors are the reason a milligram of endotoxin can kill a mouse. They are the fastest, least discriminating layer of immunity: germline-encoded sensors that read conserved microbial chem

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

PI3K does not switch on a protein — it rewrites a membrane. Everything downstream follows from one chemical event: the 3-hydroxyl of a phosphoinositide is phosphorylated, PIP₂ becomes PIP₃, and every

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

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

In the periphery, co-stimulation rescues a T cell. In the thymus, the same molecules kill it. A peripheral T cell that engages its receptor without CD80 and CD86 becomes anergic; engage them and it r

Cancer immunotherapy has revolutionized treatment options, offering strategies to harness the immune system to target and destroy tumors. One emerging area of interest is the use of OX40
