Targeting complement with an inhibitor may prevent preterm birth and protect the baby’s brain

A research team at the Medical University of South Carolina reports in Cells that the complement system, part of the body's natural immune defenses, is a key driver of inflammatory responses that contribute to fetal brain inflammation and preterm birth, the latter of which is the leading cause of complications and death in newborns.

Healthy grain foods linked to improved diet quality and metabolic markers

With so much confusion around what makes a grain food truly healthy, new research now offers a clearer picture: a combination of grain foods can support better nutrition and metabolic health when they deliver on nutrient density.

New insights into pathogenic T cells offer hope for Crohn's disease treatment

The research group led by Drs. Mitsuru Arase, Mari Murakami, and Prof. Kiyoshi Takeda (Graduate School of Medicine/ Immunology Frontier Research Center at The University of Osaka) revealed that transcription factors RUNX2 and BHLHE40 play crucial roles in inducing T cells involved in Crohn's disease.

Shifts in meal timing predict health and longevity in older adults

As we age, what and how much we eat tends to change. However, how meal timing relates to our health remains less understood. Researchers at Mass General Brigham and their collaborators studied changes to meal timing in older adults and discovered people experience gradual shifts in when they eat meals as they age.

Neuritin 1 unlocks new pathway to treat obesity without reducing food intake

Is it possible to treat obesity without reducing food intake? A new study co-led by Dr. Antonio Zorzano and Dr. Manuela Sánchez-Feutrie at the Institute for Research in Biomedicine (IRB Barcelona) suggests that this might be a possibility, at least in animal models.
