Development of the hypertension disorders in pregnant women is associated with the increase of the functional activity of innate immunity cells. RT-PCR assessment of the MMP-2 and TIMP-1 synthesis by peripheral blood phagocytes showed the significant elevation of the MMP-9 mRNA expression by neutrophils in women with chronic arterial hypertension (CAH) and TIMP-1 and TIMP-2 mRNA expression by monocytes in women with CAH and preeclampsia.

Health becomes an important topic today. One current problem was how to treat the effects of metabolic diseases, such as diabetes mellitus (DM). Thus, this study used an ethanolic extract of propolis (EEP), to test their ability as the supplement in the diabetes treatment to reduce inflammation, through proinflammatory factor response, especially nuclear factor κB (NF-κB). The streptozotocin- induced diabetes mellitus (SID) mice model was used, and expression of an proinflammatory factor was analyzed in their innate immunity cells with 3 doses of EEP, i.e. 50 mg/kg body weight, 100 mg/kg body weight, and 200 mg/kg body weight. Treatment of EEP in SID with three doses treatment decrease the number of macrophages with NF-κB expression significantly with DM control group. The results of B cells with NF-κB expression showed that EEP treatment in SID could decrease in dose 1 and dose 3, but not in dose 2. Proinflammatory cytokines expression of macrophage, especially Tumor Necrosis Factor-α and Interferon-γ, with EEP treatment in SID could decrease in three doses. This study suggests that EEP could reduce inflammation by inhibiting the development of NF-κB in innate immunity cells.

Abstract The nuclear pregnane X receptor (PXR) plays a central role in regulating xenobiotic metabolism. We now report a novel role for PXR as a critical negative regulator of innate immunity after infection. Pxr −/− mice exhibited remarkably elevated pro-inflammatory cytokine and chemokine production following infection with Listeria monocytogenes (Lm). Despite the more robust innate immune response, Pxr −/− mice were highly susceptible to Lm infection. Surprisingly, disruption of the Toll-like receptor 4 (TLR4) but not TLR2 signaling restored the inflammation to normal levels and the ability to clear Lm in Pxr −/− mice. Mechanistically, the heightened inflammation in Pxr −/− mice resulted in the death of inflammatory monocytes that led to the enhanced susceptibility to Lm infection. These data demonstrated that PXR regulated pathogen-induced inflammation and host defense against Lm infection through modulating the TLR4 pathway. In summary, we discovered an apical role for PXR in regulating innate immunity. In addition, we uncovered a remarkable negative impact of the TLR4 pathway in controlling the quality of the inflammatory response and host defense against a gram-positive bacterial infection.

Guanylate-binding proteins (GBPs) have recently emerged as central orchestrators of immunity to infection, inflammation, and neoplastic diseases. Within numerous host cell types, these IFN-induced GTPases assemble into large nanomachines that execute distinct host defense activities against a wide variety of microbial pathogens. In addition, GBPs customize inflammasome responses to bacterial infection and sepsis, where they act as critical rheostats to amplify innate immunity and regulate tissue damage. Similar functions are becoming evident for metabolic inflammatory syndromes and cancer, further underscoring the importance of GBPs within infectious as well as altered homeostatic settings. A better understanding of the basic biology of these IFN-induced GTPases could thus benefit clinical approaches to a wide spectrum of important human diseases.
