With gradual ban on the use of antibiotics, the deficiency and excessive use of trace elements in intestinal health is gaining attention. In mammals, trace elements are essential for the development of the immune system, specifically T-cell proliferation,and differentiation. However, there remain significant gaps in our understanding of the effects of certain trace elements on T-cell immune phenotypes and functions in pigs. In this review, we summarize the specificity, development, subpopulations, and responses to pathogens of porcine T cells and the effects of functional trace elements(e.g., iron, copper, zinc, and selenium) on intestinal T-cell immunity during early-life health in pigs. Furthermore, we discuss the current trends of research on the crosstalk mechanisms between trace elements and T-cell immunity. The present review expands our knowledge of the association between trace elements and T-cell immunity and provides an opportunity to utilize the metabolism of trace elements as a target to treat various diseases.

Several potential oxidative agents have damaging effects on mammalian reproductive *** study was conducted to investigate the effects of glutamate(Glu)and aspartate(Asp)supplementation on antioxidant enzymes and immune defense systems in the outer scrotum of boars injected with H2O2.A total of 24 healthy boars were randomly divided into 4 treatment groups:control(basal diet,saline-treated),H2O2(basal diet,H2O2-challenged outer scrotum(1 m L kg^–1 BW)),Glu(basal diet+2%Glu,H2O2-challenged),and Asp(basal diet+2%Asp,H2O2-challenged).Our results showed that both Glu and Asp supplementation improved testicular morphology and decreased the genital index in the H2O2-treated *** and Asp administration increased the antioxidant enzyme activities and affected the testicular inflammatory cytokine secretion but had no effect on sex hormone ***,the m RNA expression of CAT,Cu Zn SOD,and GPx4 was altered in the testes and epididymis of boars treated with Asp and *** and Asp supplementation also modulated the expression of TGF-β1,IL-10,TNF-α,IL-6 and IL-1βin the testis and *** results indicate that dietary Glu and Asp supplementation might enhance antioxidant capacity and regulate the secretion and expression of inflammatory cytokines to protect the testes and epididymis of boars against oxidative stress.
