Immunology · Cytokine SignallingTNF-alpha and Inflammation: Structure, Signalling & TherapyTumour necrosis factor alpha (TNF-α) is one of the most important pro-inflammatory cytokines in the body. Sig

The human body is a complex and intricate system where various components work together to maintain health and combat potential threats. Among these essential players are the TNF cyt

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

Introduction to TNFRSF9 and Its Role in Immune ActivationTNFRSF9, also known as 4-1BB or CD137, is a co-stimulatory receptor expressed on the surface of T cells, natural killer (NK) cells

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

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

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

As atherosclerosis is a complex inflammatory disease, there are many influential biomarkers that contribute to the disease’s progression as well as biomarkers from atherosclerosis related 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

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

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

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

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

A natural killer cell decides by subtraction. It carries no rearranged antigen receptor and no memory of what it has seen. It presses a panel of germline-encoded receptors against a target and integr

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

The complex interplay between chemokines and cytokines is fundamental to the immune system's function, orchestrating the body's response to infection, inflammation, and injury. This detailed analy
