Glutamate receptors are pivotal in mediating excitatory neurotransmission in the central nervous system (CNS), playing crucial roles in synaptic transmission, plasticity, learning, and memory. The

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

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

Introduction to KIR Blockade in Cancer ImmunotherapyNatural killer (NK) cells are crucial components of the innate immune system, responsible for recognizing and destroying virally infec

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

Lymphocyte Activation Gene-3 (LAG-3) is an immune checkpoint receptor that plays a critical role in regulating T cell function. In recent years, LAG-3 has emerged as a potential target fo

The germinal centre is where antibody quality is made. A naive B cell that binds antigen does not become a source of protective, high-affinity IgG by accident. It passes through a tightly choreograph

What are Toll Like Receptors? Toll-like receptors (TLRs) are a class of proteins that play a crucial role in the immune system's defense against microbial invaders.

In the realm of immunology, the terms "immunoglobulin" and "antibody" often find themselves used interchangeably, sparking confusion among those keen on understanding the immune system's fine deta

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

In most solid tumours the largest immune population is not a T cell. It is a myeloid cell that has been recruited, expanded and re-educated by the tumour itself. Tumour-associated macrophages and mye

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

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

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 advent of immune checkpoint targeting marks a significant milestone in the oncological field, offering a beacon of hope for patients battling cancer. This innovative approach leverages the bod

The neutrophil is the most heavily armed short-lived cell in the body. It leaves the marrow with its weapons already made — granules preloaded with elastase, myeloperoxidase and defensins — and spend
