Immunopathogenesis of endometriosis - a novel look at an old problem.

This review aims to cast a look at endometriosis as a chronic and progressive gynecological disease.Endometriosis-affected tissues show a variety of pathologic features: alterations in cell growth, apoptosis, activation, angiogenesis, cell adhesion, and cytokine production. Fresh endometriotic lesions are associated with induction of an inflammatory reaction represented by overproduction of prostaglandins (PGE2), metalloproteinases (MMP-2, -3, -9), cytokines (IL-1β, IL-8, IFN-γ, TNF-α, MCP-1 and MIF) and adhesive molecules (ICAM-1, VCAM-1) and activation of synthesis of reactive oxygen and nitrogen species.

Apoptosis and secondary necrosis of neutrophils and monocytes in the immunopathogenesis of rheumatoid arthritis: a cohort study.

Rheumatoid arthritis (RA) is a progressive chronic inflammatory and autoimmune joint disease. Neutrophils and monocytes are the main target cells of innate immune defense that modulate the course of inflammatory rheumatic diseases. Dysfunctional phagocytosis is a common feature in RA.
