www.saimmunology.org.za April 2015 Update from the Executive Committee: Hi all enthusiastic colleagues… The world of South African immunology is looking ever more exciting, with networking happening through the South African Immunology Society, the Allergy Society of South Africa, the expert Committee for Immunology of the National Health Laboratory Service and academic institutions. The SAIS hopes to be a bridge and communication tool to allow all those with an interest in immunology to grow and build the field in South Africa. With South Africa’s world class academic standing together with our burden of infectious and non-communicable diseases, South Africa is well positioned to emerge as a global leader in immunology research, training, diagnostics and clinical practice. In our newsletter you will find some links to congresses and courses of interest to those working in immunology related fields, as well as funding opportunities and current events. January 2015 Please let us hear from you how to assist you in your niche area. The fields of immunology are numerous in both the basic and clinical sciences, spanning infectious diseases, allergology, vaccinology, autoimmunity, dermatology, paediatrics, medicine, obstetrics, neurology, transplantation and more. This newsletter is the voice of your society – please contribute to it, distribute it and enjoy it. Kind Regards Dr Melinda Suchard Vice president, SAIS We will also start profiling the work done by our members, so that we facilitate networking and knowledge exchange. 1 www.saimmunology.org.za April 2015 Conferences and Courses of interest: EMBO Global Exchange Lecture Course on Frontiers in innate Immunity and drug discovery, Johannesburg 6 - 10 July 2015 Lectures will deal with advances in vertebrate and invertebrate immunity, drug discovery and development. http://events.embo.org/15-innateimmunity/ 24th annual Allergy Society of South Africa (ALLSA) congress incorporating Primary Immune Deficiency School, Port Elizabeth, 3-6 September 2015 , http://www.allsa2015.co.za/index.php/pro gramme 11th Annual African Vaccinology Course, Cape Town, 9-13 November 2015 www.vacfa.uct.ac.za African Society for Immune Deficiency (ASID) conference, Algiers, 29-31 May 2015 asidcongress2015@gmail.com South African Transplantation Society Limpopo, 9-11 October 2015 www.sats.org.za) European Society for Clinical Cell Analysis (ESCCA), Sicily, 30 September-3rd October www.escca.eu January 2015 Funding opportunities: Travel grants for PhD students and post-docs to attend an international conference of choice available from Axol Bioscience (deadline 30 June): http://www.axolbio.com/page/travelgrants Claude Leon post-doc funding application deadline 31 May 2015 http://www.leonfoundation.co.za/ National Research Foundation – 2015 call schedule available at www.nrf.ac.za/division/funding/2015 -call-schedule Call for case studies Submit interesting allergy/ immunology case studies to the journal Current Allergy & Clinical Immunology.

They will only be freed once they have pledged in writing to vaccinate their children. The Taliban prohibit vaccinations and have attacked health workers. The Pakistani government has declared "war" on polio. "We have decided to deal with the refusal cases with iron hands. Anyone who refuses will be sent to jail," said Riaz Khan Mehsud, deputy commissioner of Peshawar. http://www.bbc.com/news/world-asia-31703835 Metabolic disease January 2015 Type 2 diabetes mellitus is endemic in the South African population. This paper examines the link between a population of natural killer cells resident in the visceral adipose tissue and the development of insulin resistance in mice. Stressed adipocytes activated natural killer cells to produce interferon gamma which drives macrophages into a pro-inflammatory (M1) state. Depletion of this natural killer cell population improved glucose tolerance even in mice with no natural B or T lymphocytes.

African Vaccination Week will be running under the theme: ‘Vaccination – A Gift of Life’. This provides an opportunity for countries to strengthen immunization services and systems through advocacy, education and communication tools and activities. Information on an educational symposium to be hosted at the NICD on 30 April is available at www.nicd.ac.za January 2015 Profiling our members’ work…. Each issue we will highlight a different immunology group: Clive Gray’s research lab , IDM at the University of Cape Town World Allergy Week held 13-19 April The World Allergy Association raised awareness on the human and economic burden of allergies during educational activities during this week. For more information visit http://www.worldallergy.org/worldallergyweek/ about.php Amongst a number of research projects, our focus is to understand the balance between immune activation and immune tolerance/regulation and how an imbalance towards inflammation can predispose people to risks of becoming HIV infected. 4 www.saimmunology.org.za My lab has two areas of interest: a) maternalfoetal HIV exposure and b) immune risk in the foreskin/mechanisms of medical male circumcision. With funding from the Canadian Institutes of Health Research (CIHR), we are recruiting 500 mother-infant pairs in Khayelitsha, Cape Town and in Jos, Nigeria. One of the focal points of the study is to examine T cell vaccine immunogenicity of BCG, Rotavirus, Tetanus and Pertussis in HIV exposed uninfected (HEU) and HIV unexposed controls. The hypothesis being explored is that HIV exposure in the newborn infant alters the ability to respond to vaccine immunogens and is a proxy marker of impaired immunity. Another major focus of my lab is the examination of Immune risk of HIV acquisition in the foreskin. We are seeking mechanisms that account for how asymptomatic sexually transmitted infections (STI) result in immune activation in the foreskin. One hundred and fifty adolescent boys (age range 14-24 years) have been recruited from Edendale Hospital, outside Pietmartizburg, and from Chris Hani Baragwaneth Hospital, Soweto. Foreskin tissue is being examined using confocal and epifluoresence microscopy for numbers of Langerhans’ Cells, CD4+ T cells and the number of proliferating Ki67+ cells in relation to keratin thickness (using Filaggrin). April 2015 enhanced risk of HIV infection in uncircumcised males. This is a highly collaborative study with fellow investigators at UCT (Jo-Ann Passmore and Heather 2015 Jaspan);January the Karolinska Institute, Sweden (Francesca Chiodi); Northwestern University, Chicago (Thomas Hope).
