-   IL-1beta increased activin betaA (INHBA) and follistatin (FST) mRNA expression in human foreskin fibroblasts [PMID: 21828177].
-   The activin betaA mRNA level was increased in mouse peritoneal macrophages by LPS [PMID: 10975808].
-   Follistatin is a candidate endogenous negative regulator of activin A in experimental allergic asthma [PMID: 16839410].
