Wuchereria Bancrofti Filaria Activates Human Dendritic Cells and Polarizes
ARTICLE https://doi.org/10.1038/s42003-019-0392-8 OPEN Wuchereria bancrofti filaria activates human dendritic cells and polarizes T helper 1 and regulatory T cells via toll-like receptor 4 Suprabhat Mukherjee 1,2,4,5, Anupama Karnam 2,5, Mrinmoy Das 2,5, Santi P. Sinha Babu 1 & 1234567890():,; Jagadeesh Bayry 2,3 Interaction between innate immune cells and parasite plays a key role in the immuno- pathogenesis of lymphatic filariasis. Despite being professional antigen presenting cells cri- tical for the pathogen recognition, processing and presenting the antigens for mounting T cell responses, the dendritic cell response and its role in initiating CD4+ T cell response to filaria, in particular Wuchereria bancrofti, the most prevalent microfilaria is still not clear. Herein, we demonstrate that a 70 kDa phosphorylcholine-binding W. bancrofti sheath antigen induces human dendritic cell maturation and secretion of several pro-inflammatory cytokines. Further, microfilarial sheath antigen-stimulated dendritic cells drive predominantly Th1 and regulatory T cell responses while Th17 and Th2 responses are marginal. Mechanistically, sheath antigen- induced dendritic cell maturation, and Th1 and regulatory T cell responses are mediated via toll-like receptor 4 signaling. Our data suggest that W. bancrofti sheath antigen exploits dendritic cells to mediate distinct CD4+ T cell responses and immunopathogenesis of lym- phatic filariasis. 1 Department of Zoology (Centre for Advanced Studies), Visva-Bharati University, Santiniketan 731235, India. 2 Institut National de la Santé et de la Recherche Médicale; Centre de Recherche des Cordeliers, Equipe—Immunopathologie et immuno-intervention thérapeutique, Sorbonne Universités, F-75006 Paris, France. 3 Université Paris Descartes, Sorbonne Paris Cité, F-75006 Paris, France. -

One DALY can be thought of as one lost year of “healthy” life. Taeniasis and cysticercosis have now been added to the list of Neglected Tropical Diseases (NTDs) in the WHO NTD Roadmap 2030. - 1/3 - “Bayer is committed to patients suffering from Neglected Tropical Diseases,” said Stefan Oelrich, Member of the Board of Management of Bayer AG and President of its Pharmaceuticals Division. -

Taeniasis, a Neglegted Tropical Disease in Sumatra Utara Province, Indonesia
Taeniasis, a Neglegted Tropical Disease in Sumatra Utara Province, Indonesia Umar Zein* and Indra Janis Faculty of Medicine, Universitas Islam Sumatera Utara Keywords: Taeniasis, Simalungun Regency, Neglegted Tropical Disease Abstract: Taeniasis is humans and animals infection due to Taenia or tapeworm specieses. The infection that occurs in humans because ingestion of meat and visceral organs that containing cysts as infective stage (Cystecercus larvae). The cause of taeniasis in humans are Taenia solium, Taenia saginata and Taenia asiatica. Taeniasis is one of the neglected diseases and is an unsolved problem in the world because it corelates with human behavior and lifestyle. Material and Methode: The survey was conducted from September 2017 until November 2017 ini Nagori Dolok, Village, Silau Kahaean Sub-district, Simalungun Regency, Sumatra Utara Proince, Indonesia We met some of the people who had been Taeniasis patients and conveyed the purpose of the team's arrival. From 180 patients we suspect as Taenia carriers by clinical signs and physical examination and microscopic examination of eggs and proglottid worm that passing with feces or by anal swab. Result: From 180 suspected taenia carriers, we confirmed 171 patients diagnosed as Taeniasis and we treated by Praziquantel Tablet single dose and laxative. All of patients passing proglottids (segment of the worms), taenia eggs and proglottids strands. The longest proglottids strands that we found were 10.5 meters. Conclusion: Taeniasis (Tapeworm infection) is still widely found in the district Simalungun Regency which is negleted tropical disease that needs to get the attention of the Indonesia government through the Health Office of Regency and Province. -

CDC Center for Global Health 2016 Annual Report
CDC CENTER FOR GLOBAL HEALTH (CGH) 2016 ANNUAL REPORT Photo Credit: Athit Perawongmtha Photo Credit: Ashley Greiner 2016 CENTER FOR GLOBAL HEALTH (CGH) ANNUAL REPORT Message from the Director CDC’s global health work has a clear mission: to protect and improve health globally through science, policy, partnership, and evidence- based public health action. By ensuring that countries have the capabilities to prevent, detect, and respond to or treat health threats within their borders, the Center for Global Health (CGH) helps prevent regional and global health crises that affect health, security, and economic stability abroad and at home. Rebecca Martin In 2016, CGH’s dedicated staff advanced this mission across many Director, Center for Global Health, disease goals and geographic areas around the world. This annual Centers for Disease Control report illustrates the work that has been done in 2016 and provides and Prevention a portrait of CGH’s priorities and achievements, and the work that remains. This report also illustrates why CDC’s global health work is important and how it contributes to protecting people’s health and quality of life, both in the United States and abroad. I am proud of the strategic and impactful work in CGH over the last year, often under difficult and challenging conditions. This report highlights how scientists, epidemiologists, laboratory specialists, and countless other highly-trained experts from CGH were instrumental in achieving immunization of children at risk, in pressing forward in the fight against HIV and tuberculosis (TB), and in leading the efforts to control malaria, Zika, and a collection of other dangerous diseases that still afflict far too many people. -

WHO Technical Consultation to Review the Role of Drugs in Malaria Prevention for People Living in Endemic Settings
Malaria Policy Advisory Committee Meeting 13—14 May 2020, Geneva, Switzerland Background document for Session 5 WHO technical consultation to review the role of drugs in malaria prevention for people living in endemic settings Meeting report, 16–17 October 2019, Geneva, Switzerland Summary On 16–17 October 2019, the World Health Organization (WHO) convened a Technical Consultation to review the use of medicines for malaria prevention in endemic countries and to identify opportunities to increase their impact through review of the flexibility of the recommendations for their deployment. Experts reviewed the policies and use of chemoprevention as currently endorsed by WHO, including intermittent preventive treatment in pregnancy (IPTp), intermittent preventive treatment in infants (IPTi), seasonal malaria chemoprevention (SMC) and mass drug administration (MDA) for the reduction of disease burden in emergency situations. By reviewing these strategies side-by-side for the first time, the meeting was able to consider opportunities for optimization. Additional potential applications of chemoprevention were also reviewed, and key considerations identified to develop a broader role for malaria chemoprevention in malaria-endemic populations. Key conclusions of the meeting included: • There is a need for general guidance on the broader use of chemoprevention. Chemoprevention is an important approach in the package of strategies that countries may use to decrease their malaria burden and/or move towards malaria elimination. Development of broader, more flexible guidance that builds on existing chemoprevention recommendations in specific populations is expected to support the greater, more rational use of chemoprevention and enhance its impact. • Chemoprevention strategies may be tailored to country-specific needs. Guidance should be flexible enough to enable adaptation of strategies according to the needs of different countries and settings. -
