Dietary Vitamin D3 Deficiency Increases Resistance to Leishmania (Leishmania) amazonensis Infection in Mice
Conclusion
Altogether, our results indicate that dietary VitD deficiency is able to decrease lesion growth and provide an increase in Th1 response in C57BL/6 and BALB/c mice upon L. (L.) amazonensis infection, although it does not decrease parasite burden in either of the murine models used. Thus, VitD may contribute to host susceptibility to murine tegumentary leishmaniasis. Further studies on the influence of immunonutrition in the leishmaniases are needed to better understand the immunobiology of these diseases.
