Why in news
NIMHANS researchers reported promising pre-clinical results for a non-invasive intranasal therapy using dental pulp stem cell-derived exosomes to treat Parkinson's disease in rats.
Background
The study was funded by the Indian Council of Medical Research (ICMR) and the Department of Science and Technology. The therapy showed improvements in motor coordination, dopamine levels, neurotransmitter balance, and inflammatory markers in rats.
Facts for Prelims
- S&TExosomes: Extracellular vesicles used in the study derived from dental pulp stem cells.
- BodyICMR: Indian Council of Medical Research, which funded the study.
- FactSubstantia nigra: The specific brain region affected by Parkinson's disease targeted by the therapy.
- S&TIntranasal therapy: A non-invasive delivery method for the stem cell-derived exosomes.
For Mains
