NLRP7 (NLR family pyrin domain containing 7) is a member of the NOD-like receptor family with roles in innate immunity and inflammation. Primarily studied in reproductive biology where it is crucial for placental development, NLRP7 is also expressed in immune cells and may have roles in neuroinflammation. It is characterized by an N-terminal pyrin domain (PYD), a central NACHT domain, and C-terminal leucine-rich repeats (LRRs).
NLRP7 has several cellular functions:
- Inflammasome Regulation: Can form inflammasome complexes regulating inflammatory responses
- Cytokine Processing: Involved in processing pro-inflammatory cytokines
- Immune Cell Function: Regulates macrophage and monocyte inflammatory responses
- Reproductive Biology: Essential for early embryonic development and placental formation
- Bacterial Response: Recognizes bacterial components and initiates inflammatory responses
- NLRP7 mutations cause recurrent hydatidiform mole, a rare reproductive disorder
- Mutations lead to abnormal trophoblast differentiation
- Autosomal recessive inheritance pattern
- Expressed in brain immune cells
- Potential role in neuroinflammatory conditions
- May contribute to chronic neuroinflammation in neurodegenerative diseases
NLRP7 shows distinct expression patterns:
- Uterus: High expression in endometrial tissue
- Placenta: Very high expression in trophoblast cells
- Blood: Expression in monocytes and macrophages
- Brain: Lower expression in brain tissue, primarily in microglia
