Techniques · Flow CytometryFlow Cytometry Gating: A Comprehensive GuideGating is how flow cytometry data is turned into meaningful results — a series of regions drawn on scatter and fluorescence plots

Ionotropic glutamate receptors (iGluRs) are pivotal in the fast excitatory synaptic transmission in the mammalian central nervous system (CNS). These receptors are not only crucial for normal brai

For decades, the brain has been considered an immune sanctuary, protected by the formidable blood-brain barrier. This intricate defense system, while vital for safeguarding our most complex organ, ha

What are Toll Like Receptors? Toll-like receptors (TLRs) are a class of proteins that play a crucial role in the immune system's defense against microbial invaders.

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

Immunology · NeuroscienceHistamine Receptors: H1, H2, H3 & H4 ExplainedHistamine receptors are the G protein-coupled receptors through which histamine controls allergy, gastric acid secretion, neurotr

Immunology · Flow CytometryT Cell Immunophenotyping: Markers, Subsets and Panel DesignImmunophenotyping identifies cell populations by the proteins on their surface. For T cells that means resolving n

Flow cytometry is a powerful analytical technology employed in cell biology, immunology, and oncology research. It enables the rapid measurement of physical and chemical characteristics of cells o

Immunology · Antigen PresentationDendritic Cells: Markers, Activation and SubtypesDendritic cells are the professional antigen-presenting cells that decide whether an immune response happens at all. T

Immunology · ImmunophenotypingCD Markers on B Cells: Development, Subsets and ImmunophenotypingB cells change their surface marker profile at every stage from bone marrow progenitor to antibody-secret

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

If your knockout showed a type 2 phenotype and you attributed it to Th2 cells, there is a reasonable chance you were looking at something else. Innate lymphoid cells run T-bet, GATA3 and RORγt — not

The inflammasome is one of the few innate pathways that destroys the cell it activates. A macrophage that assembles NLRP3 has committed to a decision it cannot reverse: a priming signal through TLR4

Immunology · Cell IsolationPeripheral Blood Mononuclear Cells (PBMCs): Composition, Isolation and UseMononuclear cells are the leukocytes with a single, unlobed nucleus — lymphocytes and monocytes. Is

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

Immunology · Cell BiologyCells of the Innate Immune System: Types, Functions and MarkersThe innate immune system responds within minutes, without prior exposure, using cells that recognise conserved m

Imagine a world where cancer treatment is no longer a blunt instrument but a precision-guided surgical strike, executed by the body's own immune system. For years, we have dreamed of 'smart' cells th

Glutamate receptors are pivotal in mediating excitatory neurotransmission in the central nervous system (CNS), playing crucial roles in synaptic transmission, plasticity, learning, and memory. The

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

Neuroscience · Myelin BiologyA Quick Guide to MyelinMyelin is the lipid-rich insulating sheath wrapped around nerve axons. Made by oligodendrocytes in the central nervous system and Schwann cells in t

Immunology · Myeloid CellsGranulocytes: Neutrophils, Eosinophils and BasophilsGranulocytes are the leukocytes with cytoplasmic granules and lobed nuclei — neutrophils, eosinophils and basophils. They

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

A neuron is a cell that processes and transmits information through electrical and chemical signals. There are trillions of them in the human brain, which is able to carry out so many complex

In most solid tumours the largest immune population is not a T cell. It is a myeloid cell that has been recruited, expanded and re-educated by the tumour itself. Tumour-associated macrophages and mye

Novel Gene Therapies for Cystic Fibrosis Cystic Fibrosis Cystic fibrosis (CF) is an autosomal recessive, life-limiting disease resulting from gene mutations that encode the cystic fibr

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.
