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

Immunology · Cell BiologyCells of the Innate Immune System: Types, Functions and MarkersThe innate immune system responds within minutes, without prior exposure, using cells that recognise conserved m

By Eoin Mac Réamoinn Toll-like receptors (TLRs) are renowned for their fundamental roles in innate sensing and initiating inflammatory responses. TLRs acco

Block one receptor and more than 90% of the microglia in a mouse brain are dead within a week. Not impaired — gone. Stop the block and they come back, repopulating from the survivors within another w

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

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

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

Biomarkers · InflammationC-Reactive Protein (CRP): Structure, Function and Clinical UseCRP is the most widely measured marker of inflammation in medicine — fast to rise, fast to fall, and entirely non

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

Immunology · Antigen PresentationDendritic Cells: Markers, Activation and SubtypesDendritic cells are the professional antigen-presenting cells that decide whether an immune response happens at all. T

Endocrinology · ImmunologyCortisol and the Immune ResponseCortisol is the body’s primary stress hormone — a glucocorticoid released by the adrenal gland that powerfully shapes the immune system. Actin
