Background: Ulcerative colitis (UC) is inflammatory bowel disease (IBD), characterized by chronic inflammation episodes within mucosal layer of the intestine mostly affecting colon and rectum. As the role of innate immunity in pathogenesis of disease and important role of NLRP3, the aim of this study is to investigate the association of NLRP3 SNPs with UC in Iranian patients.
Methods: Blood samples from 45 UC patients and 56 healthy subjects were tested for single nucleotide polymorphisms in rs10754558, rs3806265, rs4612666, and rs35829419 of NLRP3 gene, using real-time PCR method.
Results: Among the investigated SNPs, "GG" genotype of rs10754558 have been 2.48 times more common among UC patients (P=0.04), while "CG" genotype has indicated protective effect against UC, as more frequently found in healthy subjects.
Conclusion: Despite no significant association between three investigated SNPs and disease, "GG" and "CG" genotypes of rs10754558 have been significantly associated with disease.

Hepatocellular carcinoma (HCC) is a global health concern, ranking as the fourth leading cause of cancer-related deaths worldwide. However, the role of piwi-interacting RNAs (piRNAs) in HCC processes has not been extensively explored. Through small RNA sequencing, our study identified a specific piRNA, pir-hsa-216911, which is highly expressed in HCC cells.

Purpose: BMS-986299 is a first-in-class, NOD-, LRR-, and pyrin-domain containing-3 (NLRP3) inflammasome agonist enhancing adaptive immune and T-cell memory responses.
Materials And Methods: This was a phase-I (NCT03444753) study that assessed the safety and tolerability of intra-tumoral BMS-986299 monotherapy (part 1A) and in combination (part 1B) with nivolumab, and ipilimumab in advanced solid tumors. Reported here are single-center results.

Most of the pyroptosis inhibitors targeted Gasdermin D (GSDMD) are functioning by restraining GSDMD-N (p30) oligomerization. For the first time, this work discovered a pyroptosis inhibitor taking effect by degrading p30 and GSDMD. As the principal bioactive constituent in Erigeron breviscapus, scutellarin (SCU) assumes a pivotal role in the realm of anti-inflammatory processes.

Obesity is a global epidemic often associated with serious medical complications such as diabetes, hypertension and metabolic dysfunction-associated steatohepatitis. Considering the multifactorial nature of these diseases, medicinal plants could be a valuable therapeutic strategy as their phytoconstituents interact with multiple and relevant biological targets. In this context, Ilex paraguariensis emerges as a potential alternative to treat obesity and associated metabolic diseases since several studies have demonstrated its anti-inflammatory, anti-obesity and anti-diabetic effects.
