| 總結: | Malnutrition, which encompasses under- and over-nutrition, is responsible for an enormous morbidity and mortality burden globally. Malnutrition results from disordered nutrient assimilation but is also characterised by recurrent infections and chronic inflammation implying an underlying immune defect. Defects emerge before birth via modifications in the immunoepigenome of malnourished parents, which may contribute to intergenerational cycles of malnutrition. This review summarises key recent studies from experimental animals, in vitro models, and human cohorts and proposes that immune dysfunction is both a cause and a consequence of malnutrition. Focusing on childhood undernutrition, we highlight gaps in current understanding of immune dysfunction in malnutrition, with a view to therapeutically targeting immune pathways as novel means of reducing morbidity and mortality.
