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

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

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

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

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

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 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

Low-dose IL-2 expands regulatory T cells. High-dose IL-2 expands the cells they exist to restrain. Same cytokine, same receptor family, opposite clinical intent — and the explanation is a receptor su

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

Most immunology is written as though a T cell must first be told what to look for. Three lineages did not read that memo. γδ T cells, invariant NKT cells and MAIT cells leave the thymus with their ef

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

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

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
