Abstract:
Peritoneal resident macrophages (PRMs) have been a prominent topic in the research field of immunology due to their critical roles in immune surveillance in the peritoneal cavity. PRMs initially develop from embryonic progenitor cells and are replenished by bone marrow origin monocytes during inflammation and aging. Furthermore, PRMs have been shown to crosstalk with other cells in the peritoneal cavity to control the immune response during infection, injury, and tumorigenesis. With the advance in genetic studies, GATA-binding factor 6 (GATA6) has been identified as a lineage determining transcription factor of PRMs controlling the phenotypic and functional features of PRMs. Here, we review recent advances in the developmental origin, the phenotypic identity, and functions of PRMs, emphasizing the role of GATA6 in the pathobiology of PRMs in host defense, tissue repairing, and peritoneal tumorigenesis.
Insights
Peritoneal resident macrophages (PRMs) are crucial for immune surveillance. The transcription factor GATA6 regulates their development, function, and role in diseases like cancer.
Area of Science:
- Immunology
- Cell Biology
- Developmental Biology
Background:
- Peritoneal resident macrophages (PRMs) are key immune cells in the abdominal cavity.
- They originate from embryonic progenitors and are replenished by monocytes.
- PRMs interact with other cells to regulate immune responses.
Purpose of the Study:
- To review recent advances in PRM development, identity, and function.
- To highlight the role of GATA-binding factor 6 (GATA6) in PRM biology.
- To discuss GATA6's influence on host defense, tissue repair, and peritoneal tumorigenesis.
Main Methods:
- Literature review of recent immunological and genetic studies.
- Analysis of developmental origins and cellular replenishment of PRMs.
- Examination of GATA6's function as a lineage-determining transcription factor.
Main Results:
- GATA6 is identified as a critical regulator of PRM phenotype and function.
- PRMs play diverse roles in immunity, repair, and cancer.
- GATA6 influences PRM pathobiology in host defense and tumorigenesis.
Conclusions:
- GATA6 is essential for establishing and maintaining PRM identity and function.
- Understanding GATA6's role offers insights into peritoneal diseases.
- Targeting GATA6 pathways may have therapeutic implications for peritoneal conditions.
