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

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

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

Regulatory T cells cannot make the cytokine they depend on. FOXP3 represses the Il2 locus, so every Treg lives on IL-2 secreted by the conventional T cells it exists to restrain. That asymmetry expla

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

CB6, also known as Etesevimab, is a monoclonal antibody that targets the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein. It neutralizes the virus by preventing it from bind

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

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

CD25, a key molecule in immune regulation, is integral to the function of activated lymphocytes and regulatory T cells. It's central in mediating immune responses, with implications in autoimmune

Antibodies, or immunoglobulins, stand as critical components of the immune system, orchestrating the identification and neutralization of pathogens like viruses and bacteria. This extensive artic

An antibody's variable domains decide what it binds. Its Fc decides what happens next — and that is not a detail of formulation, it is half the mechanism. Which Fcγ receptor the constant region engag

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

For decades, the fight against cancer has been a relentless battle of incremental gains. While immunotherapies like CAR-T cell therapy have offered revolutionary hope, their personalized nature, high

For decades, the fight against cancer has been a grueling battle of attrition, with treatments often as harsh as the disease itself. But a revolutionary approach, chimeric antigen receptor (CAR)-T cel
