Chronic Inflammation: Introduction

22
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

  • To explore therapeutic strategies based on microglial response understanding.

Main Methods:

  • Literature review of microglial cell function and activation.
  • Analysis of molecular mechanisms regulating microglial inflammatory responses.
  • Synthesis of recent research on microglial pathways in CNS diseases.

Main Results:

  • Microglial cells play multifaceted roles in CNS health and disease.
  • Dysfunctional microglia exacerbate CNS inflammatory and neurodegenerative diseases.
  • Specific molecular pathways can modulate microglial activity.

Conclusions:

  • Understanding microglial activation is key to developing novel CNS therapies.
