Epidemiology Characteristics of Human Coxsackievirus A16 and Enterovirus 71 Circulating in Linyi, China, from 2009 to 2017.

In China, a rapid expansion of hand, foot, and mouth disease (HFMD) outbreaks has occurred since 2004, and HFMD has become an important issue in China. There are more than 20 types of enterovirus causing HFMD, of which coxsackievirus A16 (CA16) and enterovirus 71 (EV71) are the most common. This study aimed to analyze the epidemiological characteristics of HFMD caused by EV71 and CA16 in Linyi, Shandong province, China, from 2009 to 2017. The stool specimens and throat samples of 5,324 patients with HFMD were obtained for nucleic acid detection of enterovirus. A total of 4,040 HFMD cases were caused by viral pathogens. Of these, 1,706 cases were positive for EV71 and 1,266 were positive for CA16. These 2 virus strains appeared alternately in Linyi city. The incidence of EV71-positive and CA16-positive cases was highest in children aged 0-5 years, with male patients being predominant. This outbreak of HMFD caused by EV71 and CA16 mainly occurred between April and July and appeared alternately between the years 2011 and 2017. These results demonstrated that the epidemiological analysis of EV71 and CA16 can provide a scientific basis for the prevention and treatment of the disease.

TBK1 inhibitors: a review of patent literature (2011 - 2014).

INTRODUCTION: TANK-binding kinase 1 (TBK1) is a noncanonical IκB kinase family member that regulates the innate immune response. Misregulation of TBK1 activity can promote inflammatory disorders and oncogenesis; therefore, TBK1 inhibitors are considered a promising therapy for inflammation and cancer. AREAS COVERED: In this review, the authors provide information on the role of TBK1 in human health and on recently developed inhibitors from patents granted from 2011 to 2014. The reader will gain an understanding of the mechanisms of TBK1 function as well as the structure and biological activity of recently developed TBK1 inhibitors. Google and NCBI search engines were used to find relevant patents and clinical information using "TBK1 inhibitor" as the search term. EXPERT OPINION: The role of TBK1 in various diseases has prompted the further investigation of significant targets. Although research on TBK1 inhibitors has increased over the last few years, only a few inhibitors of this kinase have been identified. In addition, almost all of the chemical inhibitors are modified from different scaffolds and/or chemotypes of pyrimidine. Specifically, compound BX795 is the representative one, which was first patented as a potent TBK1 inhibitor. Even though some compounds have displayed interesting potential inhibition and selectivity of TBK1 in vitro and in in vivo trials, the development of more efficient and selective TBK1 inhibitors is still required.

The regulatory role of activating transcription factor 2 in inflammation.

Activating transcription factor 2 (ATF2) is a member of the leucine zipper family of DNA-binding proteins and is widely distributed in tissues including the liver, lung, spleen, and kidney. Like c-Jun and c-Fos, ATF2 responds to stress-related stimuli and may thereby influence cell proliferation, inflammation, apoptosis, oncogenesis, neurological development and function, and skeletal remodeling. Recent studies clarify the regulatory role of ATF2 in inflammation and describe potential inhibitors of this protein. In this paper, we summarize the properties and functions of ATF2 and explore potential applications of ATF2 inhibitors as tools for research and for the development of immunosuppressive and anti-inflammatory drugs.
