What You Need to Know About DupilumabWhat is Dupilumab?Dupilumab is a fully human monoclonal antibody designed to treat various chronic inflammatory diseases by inhibiting key cytokines

Regulatory T cells (Tregs) play a crucial role in maintaining immune balance by suppressing excessive immune responses that could lead to tissue damage. However, in the context of cancer,

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

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

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

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

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

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

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

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

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

The neutrophil is the most heavily armed short-lived cell in the body. It leaves the marrow with its weapons already made — granules preloaded with elastase, myeloperoxidase and defensins — and spend

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
