Deciphering the Molecular Basis of Systemic Manifestations in Cutaneous Leishmaniasis Using Integrated Bioinformatics...

Area of Science:

• Parasitology
• Bioinformatics
• Molecular Biology

Background:

• Cutaneous leishmaniasis (CL) is a neglected parasitic disease causing skin lesions and potential systemic effects.
• Understanding the molecular basis of CL systemic manifestations is crucial for effective treatment.

Purpose of the Study:

• To identify key molecular markers and mechanisms in cutaneous leishmaniasis systemic disease using bioinformatics.
• To analyze gene expression data from CL patients to uncover pathways driving systemic involvement.

Main Methods:

• Utilized bioinformatics to analyze gene expression datasets from the GEO database.
• Constructed protein-protein interaction and gene regulatory networks using STRING, HIPPIE, and miRTarBase.
• Identified key genes through network centrality analysis and performed functional enrichment using DAVID.

Main Results:

• Identified 221 differentially expressed genes (192 up-regulated, 29 down-regulated).
• Network analysis pinpointed critical genes including ICAM1, CD274, BIRC3, EZH2, and CTLA4.
• Key genes are implicated in apoptosis, autophagy, immune regulation, and TNF signaling pathways.

Conclusions:

• This study provides molecular insights into cutaneous leishmaniasis systemic effects.
• Identified potential biomarkers and therapeutic targets for targeted treatment development.
