Explore the complexities of Interleukin-10 (IL-10) signaling and regulation, a crucial aspect in immune response modulation and its dual roles in cancer development and therapy. Key Takeaways:

Ubiquitin is a small, highly conserved protein found in eukaryotic cells that plays a crucial role in regulating various cellular processes. The process of ubiquitination involves the covalent att

Understanding Myeloid Cell Networks in Cancer ImmunotherapyImmunotherapy has revolutionized cancer treatment, yet its effectiveness in re-establishing original immune responses post-therapy remains li

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

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

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

A chimeric antigen receptor is a synthetic protein wired into a real signalling pathway. The extracellular half is an antibody fragment; everything below the membrane is borrowed from the T-cell rece

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

Almost any inflammatory phenotype in a mouse can be assigned to a cytokine by taking that cytokine away. Neutralisation is the most direct causal test immunology has: inject a functional-grade antibo

Nuclear Factor Erythroid 2–Related Factor 2 (NRF2) orchestrates a principal defense mechanism against oxidative stress and plays a pivotal role in inflammation and disease pathogenesis. This artic

Signal 1 tells a T cell what it is looking at; signal 2 tells it whether to care. The same peptide–MHC engagement that launches a productive effector response can just as easily install an anergy pro

In the intricate landscape of the immune system, toll-like receptors (TLRs) play a fundamental role in the first line of defense against pathogens. These receptors, essential components of the inn

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

Every leukocyte that reaches an inflamed tissue has solved the same mechanical problem. It must stop, in under a second, against a shear flow that would otherwise sweep it past the site of infection.

CD155 is read by four different receptors, and only one of them turns the killing programme on. The nectin and nectin-like ligands induced on stressed and transformed cells are simultaneously an acti

Apoptosis is not one pathway but three routes into the same execution machinery. A death ligand at the surface, a mitochondrion that loses outer-membrane integrity, and a granzyme delivered by a cyto

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

The germinal centre is where antibody quality is made. A naive B cell that binds antigen does not become a source of protective, high-affinity IgG by accident. It passes through a tightly choreograph

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

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
