Double-stranded DNA in the cytosol is always a mistake. A virus has uncoated, a mitochondrion has ruptured, a micronucleus has burst, or a chromosome has been broken and left unrepaired. cGAS treats

The inflammasome is one of the few innate pathways that destroys the cell it activates. A macrophage that assembles NLRP3 has committed to a decision it cannot reverse: a priming signal through TLR4

Inflammasomes are complex intracellular structures that play a pivotal role in the immune response by detecting pathogenic microorganisms and sterile stressors. Their activation is a critical step

HMGB1 Functional Overview High mobility group box 1 ( HMGB1), a member of the high-mobility group (HMG) family, was first identified in the thymus in 1973 an

The STING (Stimulator of Interferon Genes) pathway plays a pivotal role in the innate immune system's response to cancerous cells and DNA viruses. Exploiting this pathway through STING activators

An antibody–drug conjugate is not a targeted drug. It is a delivery problem with an antibody bolted to the front of it. Binding is the easy part, and it is almost never the part that fails. What deci

RIG-I: Antiviral Properties in COVID-19 (SARS-CoV-2) Infection Key Points RIG-I is a cytosolic RNA h

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

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

Understanding the dynamics of sodium and potassium ions within biological systems is crucial for deciphering cellular processes and developing therapeutic strategies. Sodium and potassium indicato

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

Biochemistry · Cell SignallingPhosphorylation: Types, ATP Synthesis and Cell SignallingAdding a phosphate group is how cells both store energy and switch proteins on and off. The same chemistry underl
