The Claim

Hyaluronan, a damage-associated molecular pattern, increases the expression of NLRP1 and NLRP3 inflammasomes and inflammatory cytokines in monocytes isolated from women with preeclampsia, while progesterone and vitamin D reduce this effect in vitro.

Source: Progesterone and vitamin D downregulate the activation of the NLRP1/NLRP3 inflammasomes and TLR4-MyD88-NF-κB pathway in monocytes from pregnant women with preeclampsia.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works

1 study reviewed

In plain English

In women with a pregnancy complication called preeclampsia, a substance called hyaluronan makes immune cells more inflamed, but two other substances—progesterone and vitamin D—can calm that inflammation down in lab tests.

See the scientific wording

Hyaluronan, a damage-associated molecular pattern, increases expression of NLRP1/NLRP3 inflammasomes and inflammatory cytokines in monocytes from women with preeclampsia, while progesterone and vitamin D counteract this effect in vitro.

What the research says

1 study

Study: Progesterone and vitamin D downregulate the activation of the NLRP1/NLRP3 inflammasomes and TLR4-MyD88-NF-κB pathway in monocytes from pregnant women with preeclampsia.
In a lab test with blood cells from women with preeclampsia, a substance called hyaluronan made the cells more inflamed, but giving them progesterone or vitamin D calmed them down — just like the claim says.
