Quick Facts About EmapalumabWhat is Emapalumab?Emapalumab is a fully human monoclonal antibody that neutralizes interferon-gamma (IFN-γ). It is the first FDA-approved therapy for primary

Dozens of cytokines converge on four kinases and seven transcription factors. That compression is the problem JAK–STAT has to solve, and it is why this map is drawn as receptor, kinase and STAT colum

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

Every T-cell response begins with a protein being taken apart. Before a CD8 or CD4 T cell can see anything, an antigen has to be degraded into peptides of the right length, delivered to the right com

Both interferon families run through STAT1, and that single shared subunit is why they are so often conflated — and why conflating them is a mistake. Type I interferon assembles STAT1 into a three-pa

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 antigen tells a CD4 T cell to respond; the cytokine tells it what kind of response to make. A naive CD4⁺ T cell leaving the thymus is uncommitted. Within about seventy-two hours of engaging TCR/C

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

Understanding the immune system's intricacies requires models that accurately reflect its complexity. The rat, as a model organism, plays a crucial role in immunological research, particularly in

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

Tocilizumab reverses cytokine release syndrome within hours, and it never touches the cell that started it. That sentence contains the whole mechanism. The trigger is a T cell — engaged by a CAR, a b

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

The CD28 molecule plays a crucial role in amplifying T cell activation, which is critical for mounting effective immune responses against tumors. By engaging with co-stimulatory molecules

Cytokine-Storm-Panel: Analyten, Auswahl und Interpretation Ein Cytokine-Storm-Panel ist ein vorvalidiertes Multiplex-Assay, das aus einem einzigen Probenaliquot mehrere pro- und antiinflammatorische

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

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

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

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

Not one immune cytokine on this pathway touches bone. TNF, IL-1β, IL-6 and IL-17A all act on osteoblasts, osteocytes and synovial fibroblasts, and it is those stromal cells that decide between RANKL

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

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

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

CD4+ T cells are central to the immune system, functioning as coordinators of immune responses and regulators of immune tolerance. These cells are divided into two primary subtypes: Helpe

Immunotherapy has become a central pillar in the fight against cancer, with a focus on enhancing the body’s natural defenses. Among the molecules at the forefront of immunotherapeutic res

Cancer immunotherapy has revolutionized treatment options, offering strategies to harness the immune system to target and destroy tumors. One emerging area of interest is the use of OX40

IntroductionCancer cells have developed sophisticated mechanisms to evade the immune system, particularly through the inhibition of T-cell responses. One such mechanism involves the progr

Complete T Helper Cell Guide: Th1, Th2, Th17 & Functions - Your Ultimate Resource from Assay GenieIn this guide, we will explore the differences between TH1 and TH2 cells, their crucial r

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

Natural killer (NK) cells are a crucial component of the innate immune system and play a significant role in eliminating tumor cells. Unlike T cells, NK cells can recognize and kill cance

T cell immunoglobulin and mucin-domain containing-3 (TIM-3) is an immune checkpoint receptor that plays a pivotal role in T cell exhaustion, a state where T cells lose their ability to ef

Regulatory T cells cannot make the cytokine they depend on. FOXP3 represses the Il2 locus, so every Treg lives on IL-2 secreted by the conventional T cells it exists to restrain. That asymmetry expla

Introduction to SLAMF7 in Cancer Immunotherapy SLAMF7, also known as Signaling Lymphocytic Activation Molecule F7, is a surface receptor found on natural killer (NK) cells, T cells, plasm

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

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

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

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

Exploring the Role of TIM-3/Gal-9 in Antiparasitic ImmunityIntroductionThe immune system is a complex network of cells and molecules that work together to defend the body against pathogens, including

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

V-domain Ig suppressor of T cell activation (VISTA) is an emerging immune checkpoint receptor that plays a key role in suppressing T cell activity within the tumor microenvironment (TME).

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

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,

Immune evasion is one of the hallmarks of cancer, where tumor cells employ various strategies to suppress immune responses and prevent destruction by the body’s defense systems. CD200, a
