The Yin and Yang of Helminths: What We Learned in Cape Town

Helminths are master manipulators of the host immune system, enabling them to evade immune responses and vaccination strategies to cause chronic, debilitating infection.  Yet at the same time, these immunomodulatory capabilities can temper inflammatory and autoimmune diseases in their hosts, and offer researchers new tools and approaches for drug development against many illnesses.

This week at the Keystone Symposia meeting “Helminths: New Insights from Immunity to Global Health” in Cape Town, South Africa, global leaders from academia, industry, medicine and public health sectors discussed the latest advances in understanding these highly successful parasites.

Topics at the meeting covered a diverse array of basic biology to clinical challenges, spanning the molecular to the epidemiological including:

      • Vaccination challenges and solutions
      • Novel immunomodulatory molecules, drug targets and strategies
      • Microbiome- helminth interactions
      • Protective immune mechanisms and pathways
      • Genomic insights
      • Epidemiology and ecology of transmission

Addressing the Global Helminth Burden

Given the lack of vaccine and drug treatment options against helminths, communities and leaders are turning to public health measures to combat this epidemic—with great success. The World Health Organization is focused on identifying central modes of morbidity and transmission, with the goal of intervening at these critical points to achieve the greatest impact on the global health burden. Public health interventions focus on improving sanitation and access to clean water sources, via both infrastructure and behavioral interventions, which can dramatically reduce helminth infection rates. These include:

    • Building bridges to reduce human contact with helminth infested waters and mud.
    • Installing infrastructure to contain human waste, such as public toilets along rivers.
    • Altering behavioral practices through health education by informing people to excrete away from rivers to reduce the risk of infection in the community.
    • Vector control measures to reduce environmental reservoirs of helminths. (ie. chemotherapy or other controls against snails that harbor helminths)

Combining many of these initiatives is a synergistic and powerful means to control and dramatically reduce helminth infection and transmission rates.

Quote from Nicola Harris: The unique strength of this conference is to bring together scientists with a common interest in helminths, but employing diverse technologies to elucidate diverse aspects of helminth biology and host-immune interactions. As an immunologist, my interactions with colleagues from entirely different domains, for example epidemiology or drug discovery, most often lead to rare but priceless 'eureka' moments, which progresses my own work and ideas, and that of the field in general.
