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

Neuroscience · BiomarkersA Guide to Tau Proteins & TauopathiesTau keeps the neuronal cytoskeleton standing up. When its phosphorylation goes wrong, the same protein becomes the aggregate that defines

The tau protein is a hot topic in the scientific world right now. This little-known protein has been linked to Alzheimer's disease, Parkinson's disease, and other neurodegenerative disea

Cell Cycle · KinasesCyclins and Cyclin-Dependent Kinases: Regulation, Substrates and Mitotic ControlCDKs are inactive on their own. They require a cyclin partner, and because cyclin levels rise and fa

Cell Death · BiomarkersCleaved Caspase-3: Activation, Function and Detection in ApoptosisCaspase-3 sits at the point where apoptotic signalling becomes irreversible. It is made as an inactive proenzym

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

Cell Signalling · EnzymologyProtein Kinases: Function, Classification, Structure and InhibitorsProtein kinases transfer a phosphate group from ATP onto specific residues of target proteins, switching

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

Almost all of the TGF-β in a tissue is already there, and almost none of it is active. That single fact reorganises how the pathway should be studied. Unlike most cytokines, TGF-β is deposited into t
