Summary
A novel lysosomotropic composition of dialdehyde dextran and amphotericin B demonstrated superior therapeutic effects against systemic candidiasis in mice. This formulation improved adrenal gland function and reduced liver damage during granulomatous inflammation.
Area of Science:
- Mycology
- Pharmacology
- Immunology
Background:
- Systemic candidiasis poses a significant health threat.
- Amphotericin B is a key antifungal agent but has limitations.
- Drug delivery systems can enhance therapeutic efficacy.
Purpose of the Study:
- To evaluate the therapeutic efficacy of a novel lysosomotropic composition of dialdehyde dextran and amphotericin B.
- To compare its effects against free amphotericin B in a murine model of systemic candidiasis.
- To assess the impact on adrenal gland function and liver inflammation.
Main Methods:
- Development of a lysosomotropic composition using dialdehyde dextran and amphotericin B.
- Induction of systemic candidiasis in a mouse model.
- Administration of the novel composition and free amphotericin B.
- Assessment of therapeutic effects, adrenal gland function, and liver histopathology.
Main Results:
- The lysosomotropic composition showed greater therapeutic effect than free amphotericin B.
- Adrenal gland glucocorticoid function was normalized by the composition.
- The severity of liver destruction in late-stage granulomatous inflammation was decreased.
Conclusions:
- Lysosomotropic delivery of amphotericin B offers enhanced therapeutic benefits for systemic candidiasis.
- This formulation positively modulates host immune responses, including adrenal function.
- Dialdehyde dextran-based drug delivery holds promise for improving antifungal treatments.

01:15Antifungal Agents
Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
01:20Candidiasis
Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
