| Abstract |
Many studies reported the neuroprotective effects of angiotensin II type 1 receptor (AT1R) antagonists in Parkinson's disease (PD). However, the role of AT1R blockade on astroglial, in turn, dopaminergic functions in chronic PD is still to be studied. In the present study, telmisartan (TEL; 3 and 10 mg/kg/day; p.o), was used to study the effects AT1R blockade on astrocytic and dopaminergic functions in a chronic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of Parkinsonism (250 mg/kg, i.p, in 10 equally divided doses at 3.5 days interval) in C57BL/6 J mice. TEL significantly downregulated glial fibrillary acidic protein (GFAP), inducible nitric oxide synthase (iNOS), TNFα and IL1β expressions and nitric oxide (NO) content. Significant upregulation glial cell derived neurotrophic factor (GDNF) expression and increased glutathione (GSH) content reveal the ameliorating effects of TEL on astroglial functions. On the other hand, TEL upregulated tyrosine hydroxylase (TH), dopamine transporter (DAT), and vesicular monoamine transporter 2 (VMAT2) expressions. Finally, TEL improved dopamine and its turnover and restored locomotor performance. Present experiment reveals that TEL has the potential to alleviate astroglial functions, apart from restoring dopaminergic functions, at least in part. To conclude, TEL may be a better disease-modifying therapeutic regimen in the management of Parkinsonism, acting primarily via astroglial-dopaminergic functions. |

Attention Score in Context
This research output has an Altmetric Attention Score of 18. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 May 2023.
All research outputs
#1,833,714
of 23,724,077 outputs
Outputs from Neurotoxicity Research
#34
of 892 outputs
Outputs of similar age
#39,400
of 328,032 outputs
Outputs of similar age from Neurotoxicity Research
#1
of 14 outputs
Altmetric has tracked 23,724,077 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 92nd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 892 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.4. This one has done particularly well, scoring higher than 96% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 328,032 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 87% of its contemporaries.
We're also able to compare this research output to 14 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 99% of its contemporaries.
