Analysis of miR‐10a and IFNG Expression Before and After Treatment for Chronic Schistosomiasis mansoni

open access: yesParasite Immunology, Volume 47, Issue 6, June 2025.
ABSTRACT Mir‐10a acts in signalling pathways regulating transcription, translation, and RNA‐mediated gene silencing, while IFNG acts in the T‐cell receptor signalling pathway. Thus, both can be considered potential targets for understanding regulatory processes in chronic inflammation in patients with schistosomiasis.
