Block one receptor and more than 90% of the microglia in a mouse brain are dead within a week. Not impaired — gone. Stop the block and they come back, repopulating from the survivors within another w

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

Quick Facts About BasiliximabWhat is Basiliximab?Basiliximab is a monoclonal antibody targeting the CD25 subunit of the IL-2 receptor, primarily used to prevent organ transplant rejectio

Immunotherapy has transformed the landscape of cancer treatment by leveraging the body’s immune system to target and destroy cancer cells. A key player in this process is Inducible T-cell

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

What is a Macrophage? Macrophages are indeed a type of phagocyte, responsible for engulfing and destroying foreign particles and cellular debris. They are larger cells with more cytoplasm an

You can remove almost every B cell from an animal and barely move its antibody titre. That is not a failed experiment — it is the expected result, and it follows from one fact: CD20 is switched off a

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

A T cell does not choose which tissue to defend. The tissue chose it, during priming. A naive T cell has no tropism at all; it acquires one from the dendritic cell that activates it, and the instruct

Blocking TNF cures rheumatoid arthritis in some patients and triggers demyelination in others. That is not a dosing problem, and it is not a patient-selection problem. It is the direct consequence of

Toll-like receptors are the reason a milligram of endotoxin can kill a mouse. They are the fastest, least discriminating layer of immunity: germline-encoded sensors that read conserved microbial chem

An agonist antibody does not activate its receptor. It gets held still by something else, and the receptors underneath cluster because they are crowded. That sentence sounds like a technicality and i

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

In the periphery, co-stimulation rescues a T cell. In the thymus, the same molecules kill it. A peripheral T cell that engages its receptor without CD80 and CD86 becomes anergic; engage them and it r

The neutrophil is the most heavily armed short-lived cell in the body. It leaves the marrow with its weapons already made — granules preloaded with elastase, myeloperoxidase and defensins — and spend

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

Double-stranded DNA in the cytosol is always a mistake. A virus has uncoated, a mitochondrion has ruptured, a micronucleus has burst, or a chromosome has been broken and left unrepaired. cGAS treats

Cell Signalling · InflammationMAPK Signalling in Inflammatory Cytokine PathwaysMAPK cascades convert receptor engagement into changes in gene expression, and in inflammation they do it in both directi

In the intricate tapestry of the immune system, macrophages play a pivotal role, orchestrating a wide range of biological responses that protect the body against pathogens, remove cellular debris,

Inflammasomes are complex intracellular structures that play a pivotal role in the immune response by detecting pathogenic microorganisms and sterile stressors. Their activation is a critical step

A macrophage does not decide to eat; it counts votes. Every particle it touches carries a mixture of pro-phagocytic and inhibitory ligands, and engulfment follows only when the activating tally clear
