Antigen's are foreign molecules recognised by the immune system. Antigens can be protein, carbohydrate, lipid or nucleic acid molecules. Examples include viruses and bacteria as well as fr

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

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

In 2006, upon completion of the Human Genome Project, it was discovered that nearly 8% of the human genome is made up of viral DNA. These viral remnants are composed of ancient germl

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 are MHC Class I molecules? The MHC class I is a glycoprotein that is expressed on all nucleated cells of the human body. MHC class I are important in disease defense against viruses, ba

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
