Regulatory T Cells and Nanomaterials: Dual Perspectives in Therapeutics and Immunomodulation

Small Science, Volume 6, Issue 1, January 2026.
Tregs control immune tolerance but can also enable tumor escape. Nanomaterials can now expand or stabilize Tregs to treat autoimmunity and support transplantation or conversely disrupt tumor Tregs to boost antitumor immunity. We also discuss unintended Treg modulation by nanoparticles, safety and manufacturing challenges, and future translational ...

How Are Adolescents Participating in the Transformation of Healthy Food Environments? A Scoping Review of Empirical Research

Obesity Reviews, Volume 27, Issue 1, Page 1-19, January 2026.
ABSTRACT Adolescence (10–19 years) is a pivotal life stage, presenting both risks and opportunities for optimizing nutrition. There are global calls advocating for adolescents to play a central role in transforming food environments. The extent to which adolescents have participated in research to improve food environments is unknown.

On Non-Gaussianity in the Curvaton Scenario [PDF]

, 2003
Since a positive future detection of non-linearity in the cosmic microwave background anisotropy pattern might allow to descriminate among different mechanisms giving rise to cosmological adiabatic perturbations, we study the evolution of the second ...

Therapeutic Targeting of Endothelial Ligands for L-selectin (PNAd) in a Sheep Model of Asthma [PDF]

The American Journal of Pathology, 2005
The homing of lymphocytes to peripheral lymph nodes is initiated by an adhesive interaction between L-selectin on lymphocytes and PNAd, a set of sialomucins that are constitutively displayed on high endothelial venules of lymph nodes. PNAd is defined by monoclonal antibody MECA-79 that recognizes a sulfated oligosaccharide carried by the sialomucins ...
