About this Research Topic

Background

Schistosomiasis continues to be a significant issue impacting public health. Schistosoma sp. is a human parasite that utilizes components from its host blood for nutrition and survival. In order to penetrate the host skin, the aquatic form of Schistosoma, the cercariae, releases serine proteases. The parasitic worm, once fully matured, releases cathepsins or cysteine proteases that play a crucial role in its ability to extract essential nutrients from the host’s blood effectively. This mechanism not only secures the worm’s nourishment but also facilitates its survival and shields it from the host’s immune system. Different cathepsins can be identified that differ in their specificities and share similarities in sequence and structure. Significant distinctions exist among the three species of Schistosoma in terms of the specific types of proteases they possess. Consequently, these differences impact their respective abilities to invade the host and elude immune responses.

This research topic aims to investigate the proteases secreted by different forms of the Schistosoma parasite, with a focus on understanding their role in evading the host’s immune system. The specific objectives are to examine the variations in protease composition among different Schistosoma species and to elucidate how these enzymes strategically function regarding essential components in the host’s blood. Additionally, this article collection seeks to unravel the host’s immune responses aimed at neutralizing these proteases. By understanding the host’s defense mechanisms, valuable insights can be gained to inform the development of efficient therapeutics or remedies for schistosomiasis, specifically targeting the parasite’s proteases.

To gather further insights into the complex interplay between Schistosoma species, their secreted proteases, and the host immune response, we welcome articles addressing, but not limited to, the following themes:

- Schistosoma immune evasion cathepsins types
- Serine proteases differences between Schistosoma sp.
- Evaded immune molecules such as complement molecules
- Host mechanisms and memory innate specific evasion
- Adaptive immune escape immunometabolism during infection

We encourage contributions from experts in Schistosoma species, particularly those with experience in parasite immune evasion, cathepsins, and serine proteases. Additionally, insights into host immune mechanisms, including immune memory, are highly valued to further enrich our understanding of these interactions.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
