Ulcerative colitis (UC) is characterized by chronic inflammation of the large intestine with involvement of Th17 cells and interleukin (IL)-17A. The role of IL17A and IL17A receptor (IL17RA) variants in pathophysiology of UC still remains inconclusive. The aim was to evaluate the association between IL17A and IL17RA variants with susceptibility, IL-17A plasma levels, and endoscopic activity in UC.

Interleukin (IL)-18 is a pro-inflammatory cytokine that seems to play a role in migraine pathophysiology, and its genetic variants could potentially impact susceptibility to migraine.
Objective: To investigate the association between IL18 rs360717 and rs187238 genetic variants with migraine diagnosis and its clinical characteristics.
Purpose: The study evaluated the relationship between the CTLA4 rs231775 (+49A>G) and rs231779 (+1822C>T) variants and susceptibility, stage, prognosis and response to treatment of the urothelial bladder cancer (UBC).
Methods: A total of 140 patients with UBC and 145 controls were enrolled. The patients were stratified as non-muscle invasive bladder cancer (NMIBC) and muscle invasive bladder cancer (MICB), metastasis, recurrence, low/moderate/high/very high risk.
The extracellular matrix surrounding the tumor undergoes changes in its organization during the metastasis process. The present study aims to quantify total collagen, collagen I (Col I) and collagen III (Col III), analyze the alignment of collagen fibers and assess the basement membrane integrity in samples from patients with metastatic and non-metastatic prostate cancer. Tissue samples from 60 patients were classified into groups based on prognostic parameters: better prognosis (n = 20), worse prognosis without metastasis (n = 23) and metastatic (n = 17).
