A groundbreaking new study has revealed the essential role of an immune molecule, interleukin 34 (IL34), in fine-tuning brain development—a discovery that could reshape understanding of neurodevelopmental and neurodegenerative disorders. Conducted by researchers at Duke University and published in the journal Immunity on July 2, 2025, the study finds that IL34 acts as a key messenger, directing the brain’s own immune cells, known as microglia, on when and how to “prune” connections between neurons in early life. This process of synaptic pruning is fundamental, as it creates stronger, more efficient neural pathways underlying emotion, decision-making, and learning abilities (Duke University Medical School).

A new study identifies interleukin-34 (IL-34) as a critical cue that guides early brain development by directing microglia, the brain’s immune cells, on when to prune synapses. Proper IL-34 timing helps build resilient neural networks and supports later emotional health, learning, and cognition. Researchers describe IL-34 as a signal that tells microglia when to start and stop pruning during infancy.

Traditionally, microglia were seen mainly as defenders against infection. The findings now show they actively shape brain architecture as well. Supported by national health research funding and dementia-focused philanthropic support, the work demonstrates that normal IL-34 signaling enables microglia to engage at the right moments. When IL-34 functions correctly, pruning proceeds in a balanced, developmentally appropriate way.

A new study published in Developmental Psychology highlights how responsive parenting can shape the emotional brain of babies with sensitive or turbulent temperaments. When caregivers consistently attune to a baby’s cues, the developing brain shows patterns linked to better emotional regulation and empathy. The findings hold significance for Thai families and global parenting practices alike, suggesting adaptive caregiving supports long-term resilience.

About 20% of newborns are naturally highly sensitive—quick to startle, easily upset, and slow to settle. If these traits are not buffered by positive caregiving, they can increase the risk of later emotional challenges, including anxiety. In Thailand’s context, where harmony and self-control are valued, supporting healthy emotional development is a priority for parents and educators, and aligns with public health goals to reduce behavioral and academic difficulties.

A new study published just days ago in “Developmental Psychology” has spotlighted the remarkable impact of responsive parenting on infants born with sensitive or “turbulent” temperaments—a revelation with far-reaching significance for Thai families and global parenting practices alike (Neuroscience News). Researchers report that attuned caregiving, in which parents accurately and consistently respond to a baby’s cues, can “rewire” the developing brain to foster better emotional regulation and empathy, especially in babies most at risk for later anxiety and emotional difficulties.

A growing body of international research shows that grandparents are shouldering unprecedented levels of childcare—transforming not only family relationships but also the way societies must support both the elderly and the youngest generations. Recent reports, including one from The Atlantic published in April 2025, highlight “an age of peak grandparenting,” with nearly 60% of American grandmothers providing childcare for grandchildren, and more than 40% seeing a grandchild weekly. Experts warn that the consequences of this shift are profound, shaping retirement, family bonds, and child development not just in the West but across Asia—including Thailand, where traditional family structures and rapid societal changes intersect in unique ways.

Grandparents are taking an increasingly central role in childcare worldwide, reshaping family life and pressuring social systems to adapt. Recent research highlights a trend toward “an age of peak grandparenting,” with many grandparents providing regular care and support for working parents. In Thailand, rapid urbanization, shifting family structures, and an aging population mean grandparent involvement has grown in both importance and complexity.

Why this matters for Thai readers. Traditionally, Thai families relied on multigenerational support, with grandparents passing down culture and often stepping in to care for children. As more parents work outside the home and cities expand, older family members frequently shoulder caregiving duties, sometimes due to limited affordable formal care. In Bangkok and rural areas alike, data from UNICEF Thailand indicate that a notable share of young children live with grandparents or other extended family. This pattern affects child development, elder health, and household finances, underscoring the need for effective support systems.
