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

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

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

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

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

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
