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

Anticorps pour Western : comment choisir sans se tromper Pour un Western fiable, privilégiez un anticorps validé qui reconnaît spécifiquement l’épitope dénaturé de votre cible, avec un monoclonal si

Nod-like receptors Nod like receptors (NLRs) are a versatile family of relatively recently discovered intracellular receptors which have a br

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

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

Introduction Cellular senescence is a fascinating phenomenon that plays a crucial role in the aging process and various age-related diseases. It is essential to explore the cellular

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

Cell Biology · PathologyNecrosis: Types, Causes, Mechanisms and How It Is MeasuredNecrosis is cell death accompanied by membrane rupture and release of intracellular contents — which is what makes it

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

Acetylation, a chemical process characterized by the addition of an acetyl functional group to a molecule, stands as a cornerstone in both biochemical and biological landscapes. Its significanc
