IL1B and hydrops fetalis: Pharmacological inhibition of autophagy by using phosphotidyl inositol 3 kinase inhibitors 3-methyl adenine (3-MA) or Wortmannin [33,34], lysosomal inhibitor Bafilomycin A1, or knockdown of autophagy gene ATG16L1 in macrophages resulted in elevated levels of IL-1β in LPS plus HF–stimulated cells compared to their controls (Fig 4G–4I and S9B Fig).
