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

Almost any inflammatory phenotype in a mouse can be assigned to a cytokine by taking that cytokine away. Neutralisation is the most direct causal test immunology has: inject a functional-grade antibo

Dozens of cytokines converge on four kinases and seven transcription factors. That compression is the problem JAK–STAT has to solve, and it is why this map is drawn as receptor, kinase and STAT colum

Both interferon families run through STAT1, and that single shared subunit is why they are so often conflated — and why conflating them is a mistake. Type I interferon assembles STAT1 into a three-pa

As atherosclerosis is a complex inflammatory disease, there are many influential biomarkers that contribute to the disease’s progression as well as biomarkers from atherosclerosis related di

Every T-cell response begins with a protein being taken apart. Before a CD8 or CD4 T cell can see anything, an antigen has to be degraded into peptides of the right length, delivered to the right com

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 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.

Non-Human Primate (NHP) Multiplex ELISA & Cytokine Panels | Assay Genie

Double-stranded DNA in the cytosol is always a mistake. A virus has uncoated, a mitochondrion has ruptured, a micronucleus has burst, or a chromosome has been broken and left unrepaired. cGAS treats

PD-1 gets the attention, but it is one brake among many — and the others do not work the same way. The co-inhibitory receptors are routinely drawn as interchangeable stop signs on a T cell. They are

The antigen tells a CD4 T cell to respond; the cytokine tells it what kind of response to make. A naive CD4⁺ T cell leaving the thymus is uncommitted. Within about seventy-two hours of engaging TCR/C

CD155 is read by four different receptors, and only one of them turns the killing programme on. The nectin and nectin-like ligands induced on stressed and transformed cells are simultaneously an acti

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
