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

ELISA in 10 Minuten prüfen: Praxisleitfaden für Forschende mit Checkliste Wenn Ihre ELISA-Platte kein Signal zeigt, prüfen Sie zuerst die Positivkontrolle und die Lagerung der Reagenzien. Diese beide

In the dynamic landscape of biomedical research, organoids have emerged as a groundbreaking tool, offering three-dimensional (3D) models that mimic the complex architecture and functionality of hu

In the relentless fight against cancer, immunotherapy has emerged as a beacon of hope, harnessing the body's own defenses to combat malignant cells. Yet, predicting which patients will respond to the

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

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

Quick Facts About TiragolumabWhat is Tiragolumab?Tiragolumab is an anti-TIGIT monoclonal antibody developed to enhance immune responses against cancer cells. It is currently under invest

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

Techniques · Gene DeliveryTransduction vs Transfection: Understanding Gene Delivery TechniquesTransduction and transfection are the two main routes for introducing genetic material into cells. Transdu

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

Dendritic cells (DCs) are pivotal in the immune system, orchestrating innate and adaptive immune responses. Understanding their developmental lineage pathway is crucial in immunology, particularly

Shane O’Grady, PhD student, RCSI Cancer is a disease that will, unfortunately, touch all of our lives at some point, directly or indirectly. Despite decades

Understanding Zonulin: Key Regulator of Intestinal Barrier Function Zonulin is a crucial physiological modulator of intercellular tight junctions, playing a significant role in regulating intestinal

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

Immunology · Flow CytometryT Cell Immunophenotyping: Markers, Subsets and Panel DesignImmunophenotyping identifies cell populations by the proteins on their surface. For T cells that means resolving n

A depletion experiment is only as good as the depletion you can prove. Injecting a functional-grade antibody and assuming the population is gone is the most common failure mode in in vivo immunology.
