TLR2 as a Key Mediator: Bergamottin Protects Against Lead‐Induced Renal Toxicity by Modulating Oxidative Stress and Pyroptosis Pathways

open access: yesFood Science &Nutrition, Volume 13, Issue 11, November 2025.
Bergamottin protects against lead‐induced renal damage by reducing oxidative stress and pyroptosis in C57BL/6 mice. The protective effects of BGM are mediated through TLR2 modulation, as silencing TLR2 enhances its efficacy, while overexpressing TLR2 weakens its protective action in HK‐2 cells.

The Effect of Clay‐ and Yeast‐Based Mycotoxin Binder on Performance, Lymphoid Organs, Blood Parameters, Immune Response and Haematology Parameters of Broilers Exposed to Aflatoxin B1

open access: yesVeterinary Medicine and Science, Volume 11, Issue 6, November 2025.
Broilers fed diets contaminated with 200 µg/kg AFB1 showed poor growth performance throughout the period. These adverse effects of aflatoxicosis may be associated with liver dysfunction, immune dysfunction and inflammation of immune organs. However, supplementation of 1 g/kg MAG counteracted the negative effects caused by AFB1, reducing liver ...
