How the Social Gets Under the Skin: From the Social as Signal to Society as a Metabolic Milieu

Abstract

Inflammation has risen to the forefront of biomedical research into many chronic diseases prevalent in industrialized countries, including mental, metabolic, and postviral conditions. For sociologists, the rise of inflammation in explanatory models of chronic disease is an opportunity to grasp a historical shift in thinking about how society gets under the skin as new modes of conceptualization of the relationship between societies and bodies emerge in this domain. Highlighting two historical conjunctures between epidemiology and molecular biology concerning hormones and fat, this paper thereby contrasts an older cybernetic model of the social as a signal transduced via the brain and hormonal signaling system to become a biological accretion of stress or adversity with an explanatory trajectory centered on chronic inflammation. Rather than transducing the social environment, the inflammatory body emerging from the studies of adiposity and diabetes is produced by metabolizing material and psychosocial conditions. Inequalities in the social world are thereby reflected as inflammatory states that exist upstream of, not downstream to, the kinds of social signals previously deemed important to health and health disparities. Signals still matter, but they are not their own key determinant in terms of action or impact—that is a contextual matter within the chronicity of the processual metabolic life of a cellular and bodily milieu.
