Special Issue Information
Dear Colleagues,
At present, drug treatment is the only therapeutic intervention for Chagas disease and human leishmaniasis, as well as for human and animal African trypanosomiasis. These diseases are caused by the single-cell protozoan parasites Trypanosoma cruzi and Leishmania spp., and by T. brucei and a group of trypanosomatids including T. congolense, T. evansi, and T. vivax. All these pathogens are classified in the family Trypanosomatidae (class Kinetoplastea; order: Trypanosomatida); their life-cycles involve an insect vector stage, and usually lead to chronic infections. Biologically, T. cruzi and Leishmania spp. have an obliged intracellular replicative stage in mammals, while the rest are free-living in the bloodstream.
In common with other Neglected Tropical Diseases, antitrypanosomatid chemotherapies either entail long-term regimens of administration and/or have severe toxicity associated, compromising treatment adherence. Additionally, treatment efficacies during the chronic phase can be variable, and the appearance of drug resistances has been documented. Therefore, availability of protective or therapeutic vaccines for them would mean a breakthrough towards controlling their impact, which collectively affects several hundred million people worldwide.
In the last decade, vaccine development efforts have intensified, but the vast majority of the candidates under study have not gone beyond preclinical evaluation. In part, this is due to the fact that trypanosomatid parasites have evolved a plethora of immune evasion mechanisms. Thus, achieving a better understanding of the complex interactions between these pathogens and their hosts´ immune systems could greatly contribute to finding vaccines against them.
Accordingly, Pathogens is launching a Special Issue devoted to “Immunity and Vaccine Development Efforts against Trypanosomatid Parasites”. This Special Issue will welcome both original research and review articles. Potential topics include but are not limited to the following:
- Trypanosomatid parasites–host immunity interactions;
- Identification of pathogenic mechanisms in trypanosomatid diseases;
- Design and evaluation of vaccine candidates;
- Use of novel vaccinology approaches.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pathogens is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
