Asthma is a chronic inflammatory disease of the airway that comprises a variety of etiologies and inflammatory phenotypes. Clinically, there is a wide range of patients with varying severities and responses to individual drugs. The introduction of inhaled corticosteroid therapy has dramatically changed the treatment of asthma. Recent development of new therapies suggests the possibility of another breakthrough. These can be categorized as follows: anti-cytokine therapies that usually target eosinophilic inflammation, sublingual immunotherapy, and bronchial thermoplasty. In this paper, we will review the major articles related to asthma treatment that were published in 2013.

Recent studies suggest that inflammatory events are implicated in a variety of human diseases including cancer and neurodegenerative diseases. It has been reported that expression of inducible cyclooxygenase (COX) and nitric oxide (NO) synthase and subsequent production of prostaglandins (PG)s and NO, respectively are elevated in many inflammatory disorders.(omitted)

Fecal calprotectin (FC) is a calcium- and zinc-binding protein of the S100 family, mainly expressed by neutrophils and released during inflammation. FC became an increasingly useful tool both for gastroenterologists and for general practitioners for distinguishing inflammatory bowel disease (IBD) from irritable bowel syndrome. Increasing evidences support the use of this biomarker for diagnosis, follow-up and evaluation of response to therapy of several pediatric gastrointestinal diseases, ranging from IBD to nonspecific colitis and necrotizing enterocolitis. This article summarizes the current literature on the use of FC in clinical practice.

The immune system is finely balanced by the activities of pro-inflammatory and anti-inflammatory mediators or cytokines. Unregulated activities of these mediators can lead to the development of various inflammatory diseases. A variety of safe and effective anti-inflammatory agents are available with many more drugs under development. Of the natural compounds, the sesquiterpenes (nootkatone, ${\alpha}$-cyperone, valencene and ${\alpha}$-selinene) isolated from C. rotundus L. have received much attention because of their potential antiinflammatory effects. However, limited studies have been reported regarding the influence of sesquiterpene structure on anti-inflammatory activity. In the present study, the anti-inflammatory potential of four structurally divergent sesquiterpenes was evaluated in lipopolysaccaride (LPS)-stimulated RAW 264.7 cells, murine macrophages. Among the four sesquiterpenes, ${\alpha}$-cyperone and nootkatone, showed stronger anti-inflammatory and a potent NF-${\kappa}B$ inhibitory effect on LPS-stimulated RAW 264.7 cells. Molecular analysis revealed that various inflammatory enzymes (iNOS and COX-2) were reduced significantly and this correlated with downregulation of the NF-${\kappa}B$ signaling pathway. Additionally, electrophoretic mobility shift assays (EMSA) elucidated that nootkatone and ${\alpha}$-cyperone dramatically suppressed LPS-induced NF-${\kappa}B$-DNA binding activity using 32Plabeled NF-${\kappa}B$ probe. Hence, our data suggest that ${\alpha}$-cyperone and nootkatone are potential therapeutic agents for inflammatory diseases.

본 연구에서는 HMGB1 의해 증가되는 각종 염증관련물질에 대해 라이코펜이 가지는 저해 역할을 규명하고 하였다. 라이코펜은 HMGB1에 의해 증가되는 MCP-1, IL-8, sPLA2-IIA, PGE2의 발현을 NF-${\kappa}B$ 그리고 TNF-${\alpha}$의 활성를 저해함으로써 감소시켰다. 특히, 1 mM에서 그 효능이 통계적으로 유효하였다. 결론적으로 HMGB1에 의해서 발생하는 각종 혈관염증질환에서 라이코펜은 증가하는 각종 염증관련물질을 저해하였고, 결국 라이코펜이 패혈증을 포함하는 염증질환을 효과적으로 치료할 수 있는 방법에 있어 많은 방향성을 제시할 것으로 기대한다.

Background: Korean ginseng (Panax ginseng) plays an anti-inflammatory role in a variety of inflammatory diseases such as gastritis, hepatitis, and colitis. However, inflammation-regulatory activity of the calyx of the P. ginseng berry has not been thoroughly evaluated. To understand whether the calyx portion of the P. ginseng berry is able to ameliorate inflammatory processes, an ethanolic extract of P. ginseng berry calyx (Pg-C-EE) was prepared, and lipopolysaccharide-activated macrophages and HEK293 cells transfected with inflammation-regulatory proteins were used to test the anti-inflammatory action of Pg-C-EE. Methods: The ginsenoside contents of Pg-C-EE were analyzed by HPLC. Suppressive activity of Pg-C-EE on NO production, inflammatory gene expression, transcriptional activation, and inflammation signaling events were examined using the Griess assay, reverse transcription-polymerization chain reaction, luciferase activity reporter gene assay, and immunoblotting analysis. Results: Pg-C-EE reduced NO production and diminished mRNA expression of inflammatory genes such as cyclooxygenase-2, inducible NO synthase, and tumor necrosis factor-${\alpha}$ in a dose-dependent manner. This extract suppressed luciferase activity induced only by nuclear factor-${\kappa}B$. Interestingly, immunoblotting analysis results demonstrated that Pg-C-EE reduced the activities of protein kinase B (AKT)1 and AKT2. Conclusion: These results suggest that Pg-C-EE may have nuclear-factor-${\kappa}B$-targeted anti-inflammatory properties through suppression of AKT. The calyx of the P. ginseng berry is an underused part of the ginseng plant, and development of calyx-derived extracts may be useful for treatment of inflammatory diseases.

Objectives : This study was conducted to investigate the research trends of herbal medicine prescriptions and herbal medicines with anti-inflammatory effects. Methods : Among the papers published in oriental medicine from 2015 to 2020(1st half), experimental papers to reveal anti-inflammatory effects were collected, and finally 198 papers were selected. The anti-inflammatory effects of each herb were summarized, and were analyzed by year, journal, experimental subjects and experimental types. Results : 1. Of the 198 papers, there were 186 papers proving anti-inflammatory drug efficacy, 6 papers comparing efficacy between drugs, and 6 papers comparing the efficacy of packaging or storage of drugs. 2. The number of anti-inflammatory drug articles published from 2015 to the first half of 2020 was 35(2015), 35(2016), 38(2017), 44(2018), 34(2019), 12(2020). 3. Papers were published in a total of 18 journals, of which 58(29.3%) were published by the Korea Journal of Herbology. 4. There were 101 papers on single herbs(51.0%) and 78(39.4%) papers on combination drugs. 71 types of single herbs were used in a total of 101 papers, of which Cheongyeol was the most common with 28. 5. Of the 198 papers, 87 in vivo papers and 125 in vitro papers were published, and 14 papers were both conducted. In vitro experiments demonstrated the efficacy of anti-inflammatory drugs in various inflammatory indicators such as NO, PGE2, and in vivo experiments demonstrated the efficacy of anti-inflammatory drugs in various inflammatory diseases such as musculoskeletal, digestive, dermal diseases.

Innate lymphoid cells (ILCs) are the most recently discovered family of innate immune cells. ILCs can be categorized into three groups on the basis of the transcription factors that direct their functions and the cytokines they produce. Notably, these functions parallel the effector functions of T lymphocytes. ILCs play a frontline role in host defense and tissue homeostasis by responding rapidly to environmental factors, conducting effector responses in a tissue-specific manner, and interacting with hematopoietic and non-hematopoietic cells throughout the body. Moreover, recent studies reveal that ILCs are involved in development of various inflammatory diseases, such as respiratory diseases, autoimmune diseases, or cancer. In this review, we discuss the recent findings regarding the biology of ILCs in health and inflammatory diseases.

Hepatic macrophages are key immune cells associated with the broad ranges of liver diseases including steatosis, inflammation and fibrosis. Hepatic macrophages interact with other immune cells and orchestrate hepatic immune circumstances. Recently, the heterogenous populations of hepatic macrophages have been discovered termed residential Kupffer cells and monocyte-derived macrophages, and identified their distinct population dynamics during the progression of various liver diseases. Liver injury lead to Kupffer cells activation with induction of inflammatory cytokines and chemokines, which triggers recruitment of inflammatory monocyte-derived macrophages. To understand liver pathology, the functions of different subtypes of liver macrophages should be regarded with different perspectives. In this review, we summarize recent advances in the roles of hepatic macrophages under liver damages and suggest hepatic macrophages as promising therapeutic targets for treating liver diseases.
