They evaluated biomarkers of inflammation and immune activation in 53 people, ages 25 to 40, who grew up in poor families. Those whose mothers expressed warmth toward them showed less production or activity of three pro-inflammatory factors, compared with those who grew up in similar settings but whose mothers treated them with less warmth, said the researchers, in July issue of Molecular Psychiatry.

This study suggests the possibility that the detrimental immunologic effects of low socioeconomic environments early in life may be partly offset by life in a supportive family.
