Withholding iron dextran treatment normally given to pigs at 1-3 days of age to prevent anemia resulted also in neutropenia. Polyinosinic acid:polycytidylic acid (poly I:C) at 0.5 mg/kg IV at 25 days of age resulted in induction of putative interferon 2 to 24 hours later, with significantly (P less than 0.05) lower concentrations in iron-deficient (Fe-) female pigs than in iron-supplemented (Fe+) female pigs. Poly I:C caused several transient toxic manifestations, including elevations in blood urea nitrogen, creatinine, aspartate aminotransferase, potassium (K), total bilirubin and phosphorus (P), marked leukopenia (both neutropenia and lymphopenia), and declines in serum albumin, calcium, cholesterol, glucose and globulin. Certain blood chemistries before poly I:C were significantly (P less than or equal to 0.05) different: albumin, globulin, cholesterol and K were higher in females than in males; albumin, globulin, glucose, P and K were higher in Fe- than in Fe+ pigs; and total carbon dioxide was higher in Fe+ than in Fe- pigs.

The antiviral restriction factor IFN-induced transmembrane protein 3 (IFITM3) inhibits cell entry of a number of viruses, and genetic diversity within IFITM3 determines susceptibility to viral disease in humans. Here, we used the murine CMV (MCMV) model of infection to determine that IFITM3 limits herpesvirus-associated pathogenesis without directly preventing virus replication. Instead, IFITM3 promoted antiviral cellular immunity through the restriction of virus-induced lymphopenia, apoptosis-independent NK cell death, and loss of T cells. Viral disease in Ifitm3-/- mice was accompanied by elevated production of cytokines, most notably IL-6. IFITM3 inhibited IL-6 production by myeloid cells in response to replicating and nonreplicating virus as well as following stimulation with the TLR ligands Poly(I:C) and CpG. Although IL-6 promoted virus-specific T cell responses, uncontrolled IL-6 expression in Ifitm3-/- mice triggered the loss of NK cells and subsequently impaired control of MCMV replication. Thus, IFITM3 represents a checkpoint regulator of antiviral immunity that controls cytokine production to restrict viral pathogenesis. These data suggest the utility of cytokine-targeting strategies in the treatment of virus-infected individuals with impaired IFITM3 activity.
