Enhancing PD-L1 Stability: The Role of EZH2 InhibitionIn recent years, the role of PD-L1 (Programmed Death-Ligand 1) in cancer immunotherapy has garnered significant attention, particularly regarding

The T-cell receptor is the most finely calibrated detector in immunology. It must discriminate an agonist peptide present at a few dozen copies from a self peptide present at tens of thousands, and i

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

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

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

Exploring LAG-3: A Key Regulator in T Cell ImmunityLAG-3 (Lymphocyte Activation Gene-3) is an inhibitory receptor that plays a crucial role in modulating T cell activation and effector functions. This

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

For decades, the brain has been considered an immune sanctuary, protected by the formidable blood-brain barrier. This intricate defense system, while vital for safeguarding our most complex organ, ha

For decades, immunologists believed that only adaptive immunity—the sophisticated system of T cells and B cells—could form lasting memories of past infections. The innate immune system, our body's fir

The choice of appropriate cell culture supplements emerges as a crucial factor in ensuring the efficacy and consistency of experimental results. Among the various options available, two commonl

Western blotting, a cornerstone technique in molecular biology, biochemistry, and immunogenetics, is pivotal for detecting specific proteins in a sample. Its applications span various scientific f

Imagine a highly trained soldier, elite and effective, sent to the front lines of a relentless war. Day after day, they fight without rest, their supplies dwindle, and the enemy never stops coming. Ev

A chemokine gradient does not move a leukocyte anywhere. It only tells one that has already stopped which way to go. That sentence is the whole map. Trafficking is a four-step cascade and the steps a

Two asthma biologics have opposite effects on the blood eosinophil count, and both of them work. Mepolizumab empties the eosinophil compartment; dupilumab can transiently raise it. If that seems cont

Imagine a battlefield where the enemy doesn't just hide from soldiers—it actively sabotages their weapons. In the tumor microenvironment, cancer cells have evolved a devious strategy: they transfer th

The Role of CD25+FOXP3+CD45RA- Treg Cells in Cancer PrognosisIntroductionRegulatory T-cells (Treg cells) are a specialized subset of T-cells that play a pivotal role in maintaining immune homeostasis

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

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

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.

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
