Rie R Yotsu

Trop Med Infect Dis 2018 Nov 14;3(4). Epub 2018 Nov 14.

School of Tropical Medicine and Global Health, Nagasaki University, Nagasaki 852-8102, Japan.

Integration of neglected tropical diseases (NTDs) into the public health agenda has been a priority in global health for the last decade. Because a number of these diseases share not only the geographical distribution, but also a common feature which is skin involvement, bringing together a sub-group of 'skin NTDs' is one way forward to promote further integration among NTDs. With these diseases, which include leprosy, Buruli ulcer, yaws, mycetoma, lymphatic filariasis, and leishmaniasis, patients may be left with life-long deformities and disabilities when diagnosis and treatment are delayed.

Cutaneous Mycobacterial Infections.

Clin Microbiol Rev 2018 Jan 14;32(1). Epub 2018 Nov 14.

Servicio de Dermatología y Departamento de Micología, Hospital General de México, Mexico City, Mexico.

SUMMARYHumans encounter mycobacterial species due to their ubiquity in different environmental niches. In many individuals, pathogenic mycobacterial species may breach our first-line barrier defenses of the innate immune system and modulate the activation of phagocytes to cause disease of the respiratory tract or the skin and soft tissues, sometimes resulting in disseminated infection. Cutaneous mycobacterial infections may cause a wide range of clinical manifestations, which are divided into four main disease categories: (i) cutaneous manifestations of infection, (ii) Buruli ulcer caused by and other related slowly growing mycobacteria, (iii) leprosy caused by and , and (iv) cutaneous infections caused by rapidly growing mycobacteria.

Global Health Institute, École Polytechnique Fédérale de Lausanne, Lausanne, Switzerland

New drugs are needed to control the current tuberculosis (TB) pandemic caused by infection with We report here on our work with AX-35, an arylvinylpiperazine amide, and four related analogs, which are potent antitubercular agents All five compounds showed good activity against and in infected THP-1 macrophages, while displaying only mild cytotoxicity. Isolation and characterization of -resistant mutants to the arylvinylpiperazine amide derivative AX-35 revealed mutations in the gene encoding a subunit of cytochrome oxidase, one of two terminal oxidases of the electron transport chain. Cross-resistance studies, allelic exchange, transcriptomic analyses, and bioenergetic flux assays provided conclusive evidence that the cytochrome is the target of AX-35, although the compound appears to interact differently with the quinol binding pocket compared to previous QcrB inhibitors.

Sec61 blockade by mycolactone: A central mechanism in Buruli ulcer disease.

Biol Cell 2018 Nov 14;110(11):237-248. Epub 2018 Aug 14.

Division of Molecular and Cellular Function, School of Biological Sciences, Faculty of Biology, Medicine and Health, University of Manchester, Manchester, M13 9PT, UK.

Infection with Mycobacterium ulcerans results in a necrotising skin disease known as a Buruli ulcer, the pathology of which is directly linked to the bacterial production of the toxin mycolactone. Recent studies have identified the protein translocation machinery of the endoplasmic reticulum (ER) membrane as the primary cellular target of mycolactone, and shown that the toxin binds to the core subunit of the Sec61 complex. Mycolactone binding strongly inhibits the capacity of the Sec61 translocon to transport newly synthesised membrane and secretory proteins into and across the ER membrane. Read More

PLoS Negl Trop Dis 2018 03 19;12(3):e0006323. Epub 2018 Mar 19.

Department of Infectious Diseases, Austin Health, Heidelberg, Victoria, Australia.

Background: Buruli ulcer (BU) is a geographically-restricted infection caused by Mycobacterium ulcerans; contact with an endemic region is the primary risk factor for disease acquisition. Globally, efforts to estimate the incubation period of BU are often hindered as most patients reside permanently in endemic areas. However, in the south-eastern Australian state of Victoria, a significant proportion of people who acquire BU are visitors to endemic regions. Read More

Subcutaneous Granulomatous Inflammation due to Basidiobolomycosis: Case Reports of 3 Patients in Buruli Ulcer Endemic Areas in Benin.

Case Rep Pathol 2018 10;2018:1351694. Epub 2018 Jan 10.

Institute of Tropical Medicine, Nationalestraat 155, 2000 Antwerpen, Belgium.

Background: Basidiobolomycosis is a rare subcutaneous mycosis, which can be mistaken for several other diseases, such as soft tissue tumors, lymphoma, or Buruli ulcer in the preulcerative stage. Microbiological confirmation by PCR for and culture yield the most specific diagnosis, yet they are not widely available in endemic areas and with varying sensitivity. A combination of histopathological findings, namely, granulomatous inflammation with giant cells, septate hyphal fragments, and the Splendore-Hoeppli phenomenon, can confirm basidiobolomycosis in patients presenting with painless, hard induration of soft tissue.

Inhibition of Sec61-dependent translocation by mycolactone uncouples the integrated stress response from ER stress, driving cytotoxicity via translational activation of ATF4.

Cell Death Dis 2018 Mar 14;9(3):397. Epub 2018 Mar 14.

Department of Microbial Sciences, School of Biosciences and Medicine, University of Surrey, Guildford, Surrey, GU2 7XH, UK.

Mycolactone is the exotoxin virulence factor of Mycobacterium ulcerans that causes the neglected tropical disease Buruli ulcer. We recently showed it to be a broad spectrum inhibitor of Sec61-dependent co-translational translocation of proteins into the endoplasmic reticulum (ER). An outstanding question is the molecular pathway linking this to its known cytotoxicity. Read More
