10806 results for 'IL-2'

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

Quick Facts About FezakinumabWhat is Fezakinumab?Fezakinumab is a human IgG1-lambda monoclonal antibody that targets interleukin-22 (IL-22), a cytokine involved in inflammatory responses

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

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

Quick Facts About CanakinumabWhat is Canakinumab?Canakinumab is a human monoclonal antibody that targets interleukin-1 beta (IL-1β), reducing inflammation associated with various disease

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

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

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

CD25, a key molecule in immune regulation, is integral to the function of activated lymphocytes and regulatory T cells. It's central in mediating immune responses, with implications in autoimmune

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

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

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

IL-8 Overview Interleukin-8 (IL-8), also known as CXCL8, was discovered over 30 years ago as a small molecule that could promote chemotaxis and induce the production

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

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

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

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).

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

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.
