Effect of glucan on Leishmania major infection in BALB/c mice
Abstract:
The effect of glucan on Leishmania major infection was studied in BALB/c mice, which are highly susceptible to leishmania infection. Glucan (0.45 mg), or isovolumetric dextrose, was administered intraperitoneally 7, 5, 3 and 1 day before infection with L. major promastigotes. At 3, 5, 6, 8 and 10 weeks after infection, animals were killed; the liver and spleen of each animal were weighed and the parasite burden was calculated. A significant (p less than 0.01) reduction in amastigote proliferation in liver and spleen of animals pretreated with glucan was demonstrated 4, 6 and 8 weeks after infection.
Insights
Glucan pretreatment significantly reduced Leishmania major parasite proliferation in BALB/c mice. This study highlights glucan
Area of Science:
- Immunology
- Parasitology
- Pharmacology
Background:
- Leishmania major causes cutaneous leishmaniasis.
- BALB/c mice are a susceptible model for leishmaniasis.
- Glucan is a polysaccharide with immunomodulatory properties.
Purpose of the Study:
- To investigate the therapeutic effect of glucan on Leishmania major infection in mice.
- To evaluate glucan's impact on parasite burden and host immune response.
Main Methods:
- BALB/c mice were infected with Leishmania major promastigotes.
- Glucan was administered intraperitoneally before infection.
- Liver and spleen parasite burden was assessed at multiple time points post-infection.
Main Results:
- Glucan pretreatment significantly reduced Leishmania major amastigote proliferation in the liver and spleen.
- The reduction in parasite burden was observed 4, 6, and 8 weeks post-infection.
- A significant difference (p < 0.01) was noted in glucan-treated versus control groups.
Conclusions:
- Glucan demonstrates a significant protective effect against Leishmania major infection in a susceptible mouse model.
- Glucan may be a potential therapeutic agent for leishmaniasis.
- Further research is warranted to elucidate the mechanisms of glucan's action.
