Abstract
Malaria is caused by Plasmodium parasites and is one of the most
life-threatening infectious diseases in humans. Infection can result in severe
complications such as cerebral malaria, acute lung injury/acute respiratory distress
syndrome, and acute renal injury. These complications are mainly caused by P.
falciparum infection and are major causes of death associated with malaria.
There are a few species of rodent-infective malaria parasites, and mice infected with such
parasites are now widely used for screening candidate drugs and vaccines and for studying
host immune responses and pathogenesis associated with disease-related complications. We
found that mice of the NC/Jic strain infected with rodent malarial parasites exhibit
distinctive disease-related complications such as cerebral malaria and nephrotic syndrome,
in addition to a rapid increase in parasitemia. Here, we focus on the analysis of host
genetic factors that affect malarial pathogenesis and describe the characteristic
features, utility, and future prospects for exploitation of the NC/Jic strain as a novel
mouse model for malaria research.

Abstract
Dysregulated immune responses to infection, such as those encountered in sepsis, can be catastrophic. Sepsis is typically triggered by an overwhelming systemic response to an infectious agent(s) and is associated with high morbidity and mortality even under optimal critical care. Recent studies have implicated unconventional, innate-like T lymphocytes, including CD1d- and MR1-restricted T cells as effectors and/or regulators of inflammatory responses during sepsis. These cell types are typified by invariant natural killer T (iNKT) cells, variant NKT (vNKT) cells, and mucosa-associated invariant T (MAIT) cells. iNKT and vNKT cells are CD1d-restricted, lipid-reactive cells with remarkable immunoregulatory properties. MAIT cells participate in antimicrobial defense, and are restricted by major histocompatibility complex-related protein 1 (MR1), which displays microbe-derived vitamin B metabolites. Importantly, NKT and MAIT cells are rapid and potent producers of immunomodulatory cytokines. Therefore, they may be considered attractive targets during the early hyperinflammatory phase of sepsis when immediate interventions are urgently needed, and also in later phases when adjuvant immunotherapies could potentially reverse the dangerous state of immunosuppression. We will highlight recent findings that point to the significance or the therapeutic potentials of NKT and MAIT cells in sepsis and will also discuss what lies ahead in research in this area.

Augmentation of LPS-induced vascular endothelial cell growth factor production in macrophages by transforming growth factor-β1. Innate Immun 2013; 20:816-25.

Abstract
The effect of LPS on the production of vascular endothelial growth factor (VEGF) was examined using RAW 264.7 macrophage cells. LPS induced VEGF production in RAW 264.7 cells and mouse peritoneal cells. LPS induced VEGF production via the expression of hypoxia inducible factor-1α and LPS-induced VEGF production was dependent on the activation of p38 MAPK and NF-κB activation· Transforming growth factor (TGF)-β1 augmented LPS-induced VEGF production, although TGF-β1 alone did not induce VEGF production. The augmentation of LPS-induced VEGF production by TGF-β1 was inhibited by a p38 MAPK inhibitor and was correlated with the phosphorylation of Smad3. The enhancing effect of TGF-β1 on LPS-induced VEGF production was observed in vivo in the skin lesions of mice receiving a subcutaneous injection of LPS. Taken together, it is suggested that LPS induced the VEGF production in macrophages and that it was augmented by TGF-β1 in vitro and in vivo.
