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

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

What You Need to Know About InebilizumabWhat is Inebilizumab?Inebilizumab is a humanized monoclonal antibody that targets CD19, a protein expressed on B cells, to treat autoimmune diseas

You can remove almost every B cell from an animal and barely move its antibody titre. That is not a failed experiment — it is the expected result, and it follows from one fact: CD20 is switched off a

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

Tocilizumab reverses cytokine release syndrome within hours, and it never touches the cell that started it. That sentence contains the whole mechanism. The trigger is a T cell — engaged by a CAR, a b

Immunology · Antigen PresentationDendritic Cells: Markers, Activation and SubtypesDendritic cells are the professional antigen-presenting cells that decide whether an immune response happens at all. T

A depletion experiment is only as good as the depletion you can prove. Injecting a functional-grade antibody and assuming the population is gone is the most common failure mode in in vivo immunology.

Immunology · Cell IsolationPeripheral Blood Mononuclear Cells (PBMCs): Composition, Isolation and UseMononuclear cells are the leukocytes with a single, unlobed nucleus — lymphocytes and monocytes. Is

B Cell Types, Antigen Recognition & Activation A comprehensive guide to B cells! Introduction B cells, a vital component of the immune system, play

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

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 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
