Supplementary information

The progesterone-induced blocking factor (PIBF) is a protein with a molecular mass of approximately 90 kDa. It has important roles linked to cell division and immune response regulation. PIBF is produced in larger quantities in pregnancy tissues particularly by decidual and trophoblastic cells but normal lymphocytes also express it when stimulated by progesterone. Researchers often study its activity because of its potential relevance in pregnancy and immune system interactions.

Biological function summary

Researchers already documented that PIBF plays a role in modulating immune responses during pregnancy. It acts as part of a complex involving progesterone and cytokines working to prevent the mother's immune system from rejecting the fetus. PIBF achieves this by influencing the Th1/Th2 cytokine balance increasing anti-inflammatory cytokines and decreasing pro-inflammatory cytokines like IL-6 and IL-12. This helps to maintain a tolerogenic environment during pregnancy.

Pathways

The PIBF significantly affects pathways involving immune regulation and inflammation. It interacts with the hormonal pathway of progesterone linking it to the immune-modulatory functions controlled by cytokine action. The balance between these pathways ensures immune tolerance in the placenta. PIBF also shares a functional pathway with proteins such as interleukin-10 (IL-10) as they both modulate immune responses to support successful pregnancies.

PIBF has significant associations with pregnancy-related conditions and certain cancers. Abnormal PIBF levels may relate to pregnancy complications such as recurrent spontaneous abortion where immune tolerance gets disrupted. Additionally PIBF can impact tumor growth because it promotes an immunosuppressive environment similar to that observed in pregnancy potentially benefiting malignant cells. This connection suggests that PIBF along with related proteins like IL-10 could serve as a target for therapeutic interventions in these conditions.

Target data

Plays a role in ciliogenesis.. Isoform 1. Pericentriolar protein required to maintain mitotic spindle pole integrity (PubMed : 21224392). Required for the centrosomal accumulation of PCM1 and the recruitment of centriolar satellite proteins such as BBS4. Via association with PCM1 may be involved in primary cilia formation (PubMed : 23110211). Required for CEP63 centrosomal localization and its interaction with WDR62. Together with CEP63 promotes centriole duplication. Promotes the centrosomal localization of CDK2 (PubMed : 26297806).. Isoform 4. The secreted form is a mediator of progesterone that by acting on the phospholipase A2 enzyme interferes with arachidonic acid metabolism, induces a Th2 biased immune response, and by controlling decidual natural killer cells (NK) activity exerts an anti-abortive effect (PubMed : 12516630, PubMed : 14634107, PubMed : 3863495). Increases the production of Th2-type cytokines by signaling via the JAK/STAT pathway. Activates STAT6 and inhibits STAT4 phosphorylation. Signaling via a not identified receptor seems to implicate IL4R and a GPI-anchored protein (PubMed : 16393965, PubMed : 25218441).
