Systems Biology Analysis of the Effect and Mechanism of Qi-Jing-Sheng-Bai Granule on Leucopenia in Mice
Conclusion In summary, our data reveal the therapeutic mechanism of QJSB by integrative application of transcriptomics-based network pharmacology and metabolomics technologies. QJSB exerts protective effect against leucopenia in mice through participating in multi-pathways, mainly including accelerating cell proliferation and differentiation, regulating metabolism response pathways and modulating immunologic function. Ethics Statement All animal studies were performed according to the institutional ethical guidelines of animal care and were approved by the Committee on the Ethics of Animal Experiments of the Second Mili...

Early Blood Profile of C57BL/6 Mice Exposed to Chronic Unpredictable Stress
This study demonstrates that CUS leads to early and clinically relevant blood profile and biochemical changes in C57BL/6 mice that are readily detected in live animals following 10 days of CUS. While behavioral assessments are often employed to determine the impact of CUS on depressive and anxious response, interpretation of results can be challenging due to strain-specific responses (26), and these changes can take 4–8 weeks to manifest (18), particularly in C57BL/6 mice. In this study, stress response was verified based on corticosterone levels, wherein we demonstrate an acute elevation in corticosterone following...

Osteoporosis and Sarcopenia Increase Frailty Syndrome in the Elderly
Conclusions World population is aging and the increase in life expectancy is often unhealthy. In particular, musculoskeletal aging, which leads to sarcopenia and osteoporosis, has several causes such as changes in body composition, inflammation, and hormonal imbalance. Sarcopenia, osteoporosis, and more frequently, sarcopenic obesity are commonly associated with aging and frequently closely linked each other, often leading to the development of a frailty syndrome. Frailty syndrome favors an increased risk of loss function in daily activities, for cardiovascular diseases, cancers, falls, and mortality. As the number of eld...

Markers of Pulmonary Oxygen Toxicity in Hyperbaric Oxygen Therapy Using Exhaled Breath Analysis
Conclusion In this study, after daily HBOT for 6 days, we identified 11 VOCs which could be divided into two PCs. PC1 (inflammation) showed no significant changes over time, PC2 (methyl alkanes) was significantly reduced after daily exposure for 5 days, to approximately 60% after 2 days’ rest. This suggests that daily HBOT does not induce cumulative damage to the pulmonary system of healthy volunteers, but triggers an adaptive response. Additional studies including more treatment sessions, and perhaps additional systemic parameters on radical oxygen scavengers and inflammatory markers, are necessary to substantiate...

Contribution of Non-immune Cells to Activation and Modulation of the Intestinal Inflammation
Conclusions As the intestinal mucosa surface constitutes the major surface of the body which is in direct contact with the outer environment, intestinal immune homeostasis must be accurately regulated. The interplay between commensal microbiota, intestinal stromal cells, and the mucosal immune system components should guarantee the intestinal homeostasis to avoid a sustained inflammation that could induce tissue damage. However, several factors can lead to inflammation through homeostasis breakdown. Figure 1 summarizes the main points that have been reviewed here. We have described what it is known so far about the role o...

Innate Lymphoid Cells in Helminth Infections —Obligatory or Accessory?
Conclusion ILC2s are clearly an inherent feature of the immune response to helminth infection, and in all probability their evolution has been driven by the threat of parasites. While in experimental model systems they are not always found to be essential, they are often center stage, particularly in the early phases of infection of each helminth system so far analyzed. They also form an important conceptual and mechanistic link with the allergic response that will allow us to understand in more detail the genesis and control of allergic disorders. In this respect, a much fuller analysis of ILC biology and function in the...

Dietary Vitamin D3 Deficiency Increases Resistance to Leishmania (Leishmania) amazonensis Infection in Mice
Conclusion Altogether, our results indicate that dietary VitD deficiency is able to decrease lesion growth and provide an increase in Th1 response in C57BL/6 and BALB/c mice upon L. (L.) amazonensis infection, although it does not decrease parasite burden in either of the murine models used. Thus, VitD may contribute to host susceptibility to murine tegumentary leishmaniasis. Further studies on the influence of immunonutrition in the leishmaniases are needed to better understand the immunobiology of these diseases. Author Contributions HdMG conceived and designed the experiments. GO-S, DB, MM, JEP, JCP, TR, AdF-M, and L...

Qingpeng Ointment Ameliorates Inflammatory Responses and Dysregulation of Itch-Related Molecules for Its Antipruritic Effects in Experimental Allergic Contact Dermatitis
Conclusion Via a HPLC system and a BATMAN-TCM platform, for the first time we performed detailed HPLC fingerprint analysis and network pharmacology studies of QP ointment. By in-depth animal and molecular analysis, we identified a number of chronic dermatitis-associated Th1/2 cytokines, itch mediators, and cellular signaling pathways in the skin, DRG and serum for QP to treat the inflammation and chronic itch associated with ACD. Our data clearly suggested, upon stimulation, cytokines and itch-related mediators are released from the skin and neuronal tissues, and QP could effectively work on both the skin and sensory neur...

Effects of Orally Ingested Arsenic on Respiratory Epithelial Permeability to Bacteria and Small Molecules in Mice
Conclusions: Peroral arsenic has little effect on local airway immune responses to bacteria but compromises respiratory epithelial barrier integrity, increasing systemic translocation of inhaled pathogens and small molecules. https://doi.org/10.1289/EHP1878 Received: 09 March 2017 Revised: 14 August 2017 Accepted: 16 August 2017 Published: 28 September 2017 Address correspondence to M.B.
