CD40, a member of the tumor necrosis factor receptor (TNFR) superfamily, plays a pivotal role in regulating immune responses, particularly in activating antigen-presenting cells (APCs) an

What You Need to Know About IscalimabWhat is Iscalimab?Iscalimab (CFZ533) is a monoclonal antibody targeting CD40, a key protein involved in immune system regulation.What is the mechanis

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

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

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

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

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

Immunology · ImmunophenotypingCD Markers on B Cells: Development, Subsets and ImmunophenotypingB cells change their surface marker profile at every stage from bone marrow progenitor to antibody-secret

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

The mast cell is loaded long before the allergen arrives. IgE bound to FcεRIα is not waiting to be recruited the way an antibody waits for antigen in a serum assay — it is already installed on the ce

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

The human body is a complex and intricate system where various components work together to maintain health and combat potential threats. Among these essential players are the TNF cyt

Transplant rejection is the fastest, most violent adaptive immune response a body can mount — and it is a response to a molecule rather than to a pathogen. Somewhere between one and ten per cent of a

Interleukin-9 (IL-9) plays a critical role in the immune system, influencing a variety of biological functions across different immune cell types. This article provides an in-depth look at the sig

What is a Plasma Membrane? The plasma membrane, also known as the cell membrane, is a vital component of all cells. It is a thin, semi-permeable barrier that separate

Immunophenotyping by Flow Cytometry Immunophenotyping is a technique used in the field of immunology and cell biology to identify and classify cells based on the specific proteins o

By Charlotte O'Donnell PhD The genes of the IL-36 family members are located in a cluster on chromosome 2 [1]. All three activating ligands, IL-36α, IL-36β a
