Introduction Discover the multifaceted role of CD33, a critical player in immune function and disease, shaping our approach to treating cancers and neurodegenerative conditions

Key Facts About GemtuzumabWhat is Gemtuzumab?Gemtuzumab is an antibody-drug conjugate (ADC) targeting CD33, a protein expressed on the surface of myeloid cells. It is widely recognized f

The most abundant immunosuppressive molecule in a solid tumour is not a protein. It is adenosine — a metabolite, produced from ATP in two enzymatic steps, at concentrations orders of magnitude above

What is CD31? CD31, also known as PECAM-1, was originally described as a cell surface antigen present on platelets and megakaryocytes. CD31 is

Quick Info Section: Key Facts About CevostamabWhat is Cevostamab?Cevostamab is an investigational monoclonal antibody targeting CD47, a cell surface protein that helps cancer cells evade

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

Quick Info Section: Key Facts About TalquetamabWhat is Talquetamab?Talquetamab is a novel monoclonal antibody being developed for the treatment of multiple myeloma and other cancers. It

Introduction to CD39 and Cancer Immunosuppression CD39 is an ectonucleotidase enzyme that plays a crucial role in generating adenosine, a powerful immunosuppressive molecule within the tu

Key Facts About BrentuximabWhat is Brentuximab?Brentuximab is a monoclonal antibody targeting CD30, commonly used in the treatment of Hodgkin lymphoma and systemic anaplastic large cell

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.

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

The T-cell receptor is the most finely calibrated detector in immunology. It must discriminate an agonist peptide present at a few dozen copies from a self peptide present at tens of thousands, and i

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

PD-1 does not switch a T cell off; it moves the threshold. Engagement of PD-1 by PD-L1 recruits a single phosphatase into the immunological synapse, and that one recruitment event is enough to collap

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

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

PI3K does not switch on a protein — it rewrites a membrane. Everything downstream follows from one chemical event: the 3-hydroxyl of a phosphoinositide is phosphorylated, PIP₂ becomes PIP₃, and every

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

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
