Abstract:
Leishmaniasis is a vector-borne disease that affects several populations worldwide, against which there are no vaccines available and the chemotherapy is highly toxic. Depending on the species causing the infection, the disease is characterized by commitment of tissues, including the skin, mucous membranes, and internal organs. Despite the relevance of host inflammatory mediators on parasite burden control, Leishmania and host immune cells interaction may generate an exacerbated proinflammatory response that plays an important role in the development of leishmaniasis clinical manifestations. Plant-derived natural products have been recognized as bioactive agents with several properties, including anti-protozoal and anti-inflammatory activities. The present review focuses on the antileishmanial activity of plant-derived natural products that are able to modulate the inflammatory response in vitro and in vivo. The capability of crude extracts and some isolated substances in promoting an anti-inflammatory response during Leishmania infection may be used as part of an effective strategy to fight the disease.
Insights
Plant-derived natural products show promise in fighting leishmaniasis, a parasitic disease. These natural compounds can reduce inflammation and parasite load, offering a potential new treatment strategy.
Area of Science:
- Parasitology
- Immunology
- Pharmacognosy
Background:
- Leishmaniasis is a widespread vector-borne disease lacking vaccines and effective treatments.
- Current chemotherapy for leishmaniasis is toxic and its efficacy varies.
- Host immune responses, particularly inflammation, significantly influence leishmaniasis progression.
Purpose of the Study:
- To review plant-derived natural products with antileishmanial activity.
- To explore the anti-inflammatory potential of these natural products in leishmaniasis.
- To assess their efficacy in modulating host-parasite interactions.
Main Methods:
- Literature review of studies on plant extracts and isolated compounds against Leishmania.
- Analysis of in vitro and in vivo data on antileishmanial and anti-inflammatory effects.
- Evaluation of mechanisms of action related to immune modulation.
Main Results:
- Numerous plant-derived natural products exhibit significant antileishmanial activity.
- Many compounds demonstrate the ability to modulate inflammatory responses.
- Crude extracts and isolated substances show potential for reducing parasite burden and disease severity.
Conclusions:
- Plant-derived natural products represent a promising source for novel leishmaniasis treatments.
- Their dual action of direct antileishmanial effects and inflammation modulation is key.
- Further research into these natural products could lead to effective anti-leishmaniasis strategies.
