Skin models for studying vector-borne kinetoplastid infections

Area of Science:

• Parasitology
• Dermatology
• Bioengineering

Background:

• Kinetoplastid infections (Leishmania, Trypanosoma) are major global health issues, particularly in tropical regions.
• The skin is a critical site for parasite entry, persistence, and host interaction, yet mechanistic understanding is limited.
• Traditional in vivo and ex vivo models have limitations in reproducibility and accessibility.

Purpose of the Study:

• To highlight the utility of advanced bioengineered skin models for studying kinetoplastid-host interactions.
• To explore how these models can overcome limitations of existing research systems.
• To investigate parasite development, invasion, dissemination, and immune responses at the skin interface.

Main Methods:

• Development and application of advanced in vitro bioengineered skin models (full-thickness skin equivalents, skin organoids).
• Incorporation of key human skin tissue components, including immune cells and vascular structures.
• Replication of complex human skin architecture at customizable levels of detail.

Main Results:

• Bioengineered models provide a more accessible, reproducible, and anatomically relevant platform compared to traditional models.
• These systems allow for high-resolution studies of parasite-host interactions at the skin interface.
• The models support natural vector transmission and simulation of diverse biological conditions for studying parasite dynamics.

Conclusions:

• Advanced bioengineered skin models are powerful tools for advancing research on kinetoplastid skin infections.
• These in vitro systems offer novel avenues for investigating parasite pathogenesis and host immune responses.
• This approach holds promise for developing new strategies to combat neglected tropical diseases affecting the skin.
