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

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

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

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

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

Explore the complexities of Interleukin-10 (IL-10) signaling and regulation, a crucial aspect in immune response modulation and its dual roles in cancer development and therapy. Key Takeaways:
