Anggota famili POP (pyrin-only protein) termasuk POP116 dan POP216 mengeblok perakitan inflamasom dengan mengikat ASC dan menghambat perekrutan ASC ke NLRP3.<ref>{{Cite journal|last=de Almeida|first=Lucia|last2=Khare|first2=Sonal|last3=Misharin|first3=Alexander V.|last4=Patel|first4=Rajul|last5=Ratsimandresy|first5=Rojo A.|last6=Wallin|first6=Melissa C.|last7=Perlman|first7=Harris|last8=Greaves|first8=David R.|last9=Hoffman|first9=Hal M.|date=2015-08-18|title=The PYRIN Domain-only Protein POP1 Inhibits Inflammasome Assembly and Ameliorates Inflammatory Disease|url=https://pubmed.ncbi.nlm.nih.gov/26275995|journal=Immunity|volume=43|issue=2|pages=264–276|doi=10.1016/j.immuni.2015.07.018|issn=1097-4180|pmc=4666005|pmid=26275995}}</ref><ref>{{Cite journal|last=Ratsimandresy|first=Rojo A.|last2=Chu|first2=Lan H.|last3=Khare|first3=Sonal|last4=de Almeida|first4=Lucia|last5=Gangopadhyay|first5=Anu|last6=Indramohan|first6=Mohanalaxmi|last7=Misharin|first7=Alexander V.|last8=Greaves|first8=David R.|last9=Perlman|first9=Harris|date=2017-06-05|title=The PYRIN domain-only protein POP2 inhibits inflammasome priming and activation|url=https://pubmed.ncbi.nlm.nih.gov/28580931|journal=Nature Communications|volume=8|pages=15556|doi=10.1038/ncomms15556|issn=2041-1723|pmc=5465353|pmid=28580931}}</ref> Molekul regulator negatif yang menyasar pada penghabisan ion, fungsi mitokondria, dan pensinyalan ROS juga dapat mengeblok aktivasi inflamasom NLRP3.
