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

QUICK ANSWER If your ELISA returns sample concentrations that are orders of magnitude too high, the assay itself is usually fine — the error is almost always in data analysis. The most

The antigen tells a CD4 T cell to respond; the cytokine tells it what kind of response to make. A naive CD4⁺ T cell leaving the thymus is uncommitted. Within about seventy-two hours of engaging TCR/C

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 Microtubules are key components of the cytoskeleton and are composed of alpha and beta tubulin. These dimerise in a head to tail fashion to form 13 linear protofilaments.

Since I am from Ireland I thought I would give as comprehensive view as possible for Research Universities in Ireland. By now you are probably considering looking for a PhD or PostDoc positi

Two drugs aimed at the same axis can give opposite results in the same disease. Blocking IL-23p19 is highly effective in psoriasis and works in Crohn’s disease. Blocking IL-17A directly is highly eff

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

Imagine a microscopic sniper, capable of delivering a lethal blow to a single cancer cell while leaving its healthy neighbors virtually untouched. This is the promise of targeted alpha therapy, a rev

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
