PLAAT4 and brucellosis: Cytoplasmic danger receptors that belong to the NLR protein family such as nucleotide-binding oligomerization domain-like receptor family leucine-rich repeat protein (NLRP) 1, NLRP3, and NLR family caspase recruitment domain containing 4 (NLRC4), or other types of danger receptors such as AIM2 (absent In melanoma 2), IFI-16 (interferon gamma inducible protein 16), RIG-1 (retinoic acid inducible gene-1), and MEFV (mediterranean fever) induce the formation of multi-protein inflammasomes in response to engagement by according ligands [3].
