Titanium Detected in Liver, Kidney, Spleen, and Intestine Is Not Related to Dose, Time, or Route of Exposure to Titanium Dioxide: A Systematic Review

Environmental Toxicology, Volume 41, Issue 8, Page 537-548, August 2026.
ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

Thrombospondin‐4 is upregulated in abdominal aortic aneurysm: A vasoprotective response with potential therapeutic relevance

British Journal of Pharmacology, Volume 183, Issue 12, Page 3321-3339, June 2026.
TSP4 is upregulated in human and experimental AAA. TSP4 knockdown accelerated AAA formation and exacerbated both vascular inflammation and remodelling, emphasizing that TSP4 upregulation may represent a protective response against AAA. Our findings suggest that preserving TSP4 could be a useful strategy in the clinical management of AAA.
