Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

open access: yesFlavour and Fragrance Journal, Volume 41, Issue 4, Page 908-922, July 2026.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.

Humanin Mitigates Aβ‐Induced Retinal Pigment Epithelium Injury via AMPK‐Beclin1‐Dependent Mitophagy

open access: yesAging Cell, Volume 25, Issue 7, July 2026.
Humanin (HN) enhanced the clearance of Aβ‐accumulated mitochondria in the RPE while preserving retinal function and RPE barrier integrity. HN activated AMP‐activated protein kinase (AMPK), leading to phosphorylation of ULK1 and Beclin1, which promoted the interaction between Beclin1 and Parkin and their translocation to mitochondria.

Thymus and Leishmania at the Crossroads: Autoimmunity and Cancer

open access: yesImmunology, Volume 178, Issue 3, Page 377-386, July 2026.
Conceptual ‘Crossroads Model’ linking Leishmania, thymic infection and immune dysregulation: an integrative model is proposed in which Leishmania infection disrupts thymic architecture and stromal–thymocyte interactions. These alterations converge to promote defective tolerance, increased autoimmune risk and a microenvironment permissive to malignant ...
