Introduction:
Encephalitozoon cuniculi (E. cuniculi), a fungus that acts as an intracellular pathogen, causes a marked neurological syndrome in many host species and is a zoonotic concern. Although no well-established treatment for this syndrome is known, previous successful clinical experience using homeopathic phosphorus has been described in which symptom remission with no mortality occurred in 40/42 animals by means of unknown immunological mechanisms. The latter observation was the main motivation for this study.
Objective:
To verify, in an in-vitro model, if macrophages infected with E. cuniculi can change in function after treatment with different potencies of phosphorus.
Materials And Methods:
RAW 264.7 macrophages were infected with E. cuniculi in-vitro and treated with various homeopathic potencies of phosphorus. The vehicle was used as a control solution (0.06% succussed ethanol). After 1 and 24 hours, the following parameters were analyzed: parasite internalization (by the Calcofluor staining method), lysosome activity (by the acridine orange method), cytokine/chemokine production (by the MAGPIX system), and cell ultrastructure. Automatic image analysis was used when applicable, and the experiments were performed in triplicate.
Results:
Treatment with vehicle alone increased interleukin (IL)-6, tumor necrosis factor alpha and monocyte chemotactic protein -1 production (p ≤ 0.05) and reduced the number of internalized parasites (p ≤ 0.001). A progressive and time-dependent increase in RANTES (regulated on activation, normal T-cell expressed and secreted) and lysosome activity (p ≤ 0.002) was observed only after treatment with the highest potency of phosphorus (Phos 200cH), together with decreased apoptosis rate, intense parasite digestion, and the presence of non-internalized spores.
Conclusions:
Phos 200 cH has a modulatory action on the activity of infected macrophages, especially a specific increase in RANTES, a key element in the prognosis of E. cuniculi-infected and of immunosuppressed patients bearing infections.
Insights
Homeopathic phosphorus (Phos 200cH) modulated infected macrophages, increasing RANTES and lysosome activity. This suggests a potential therapeutic mechanism for Encephalitozoon cuniculi infections.
Area of Science:
- Immunology
- Microbiology
- Homeopathic Medicine
Background:
- Encephalitozoon cuniculi (E. cuniculi) is an intracellular pathogen causing neurological disease and zoonotic concerns.
- No established treatment exists, but homeopathic phosphorus showed clinical success via unknown mechanisms.
Purpose of the Study:
- To investigate if in-vitro infected macrophages change function after homeopathic phosphorus treatment.
- To analyze parasite internalization, lysosome activity, cytokine production, and cell ultrastructure.
Main Methods:
- RAW 264.7 macrophages infected with E. cuniculi were treated with varying phosphorus potencies.
- Analysis included parasite internalization, lysosome activity, cytokine/chemokine production, and cell ultrastructure.
Main Results:
- Vehicle treatment increased IL-6, TNF-alpha, MCP-1 and reduced parasite internalization.
- Phos 200cH significantly increased RANTES and lysosome activity over time.
- Phos 200cH also decreased apoptosis, enhanced parasite digestion, and reduced internalized spores.
Conclusions:
- Homeopathic phosphorus (Phos 200cH) modulates infected macrophage activity.
- A key finding is the specific increase in RANTES, crucial for E. cuniculi infection prognosis.
