Flow Cytometry · Cell SortingGuide to Fluorescence-Activated Cell Sorting (FACS)Fluorescence-activated cell sorting (FACS) is a specialised form of flow cytometry that physically isolates individual c

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

Immunophenotyping by Flow Cytometry Immunophenotyping is a technique used in the field of immunology and cell biology to identify and classify cells based on the specific proteins o

Immunology · T LymphocytesCD8+ T Cells: Cytotoxic Mechanisms, Memory and ExhaustionCD8+ T cells kill infected and transformed cells directly, and they do it with a specificity nothing else in the immu

Mouse monoclonal antibodies are a valuable tool in the biomedical field. They can be used for a variety of applications, from research to clinical diagnostics. In this blog post, we will di

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

Flow Cytometry · GatingExcluding Doublets in Flow Cytometry: Pulse Geometry and Gating StrategyTwo cells passing the laser together are recorded as one event, with roughly double the signal. In DNA co

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

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

Immunology · Innate LymphocytesNatural Killer Cells: Receptors, Subsets and FunctionNK cells kill without prior sensitisation and without antigen-specific receptors, using a balance of activating and
