Glossary Translocator Protein

protein on mitochondria involved in cholesterol transport and stress response

The Translocator Protein (TSPO), formerly known as the Peripheral Benzodiazepine Receptor (PBR), is a protein found on the outer membrane of mitochondria, the energy-producing structures in cells. It plays a crucial role in transporting cholesterol into mitochondria, which is essential for the production of steroid hormones. TSPO is also involved in cellular stress responses and inflammation, making it a target for research in various medical fields, including neurology and oncology.

research Antidepressant-like effect of fluoxetine may depend on translocator protein activity and pretest session duration in forced swimming test in mice

7 citations , October 2017 in “Behavioural Pharmacology”

This study found that the antidepressant-like effect of fluoxetine in mice was only observed when a 5-minute pretest session was conducted, and this effect was blocked by the TSPO antagonist PK11195.

research Cytoprotective effects of paeoniflorin are associated with translocator protein 18 kDa

3 citations , July 2018 in “Biomedicine & pharmacotherapy”

This study suggests that paeoniflorin's protective effects on brain astrocytes may be mediated by TSPO and neurosteroids biosynthesis.

research Ornithine Decarboxylase Expression Leads to Translocation and Activation of Protein Kinase CK2 in Vivo

52 citations , May 1997 in “Journal of Biological Chemistry”

This study suggests that polyamines regulate CK2 enzyme activity and its subcellular distribution, as demonstrated in mouse models and cell cultures with elevated levels of ornithine decarboxylase.

research Overexpression of the 18 kDa translocator protein (TSPO) in the hippocampal dentate gyrus produced anxiolytic and antidepressant-like behavioural effects

25 citations , June 2017 in “Neuropharmacology”

This study observed that overexpressing TSPO in the hippocampal dentate gyrus of mice led to significant anxiolytic and antidepressant-like effects, potentially mediated by increased allopregnanolone synthesis.

research Cyclosporin A Promotes Hair Epithelial Cell Proliferation and Modulates Protein Kinase C Expression and Translocation in Hair Epithelial Cells

45 citations , September 2001 in “Journal of Investigative Dermatology”

This study found that cyclosporin A stimulates growth in cultured murine hair epithelial cells and reduces protein kinase C expression, suggesting that these actions may contribute to its hair-growing effects.

community Hair regrowth without drugs (99% natural) 25M

528 upvotes 4 months ago

A user shared their experience with hair regrowth using supplements like NAC and DIM, and briefly using minoxidil with microneedling. They reported some improvement in hair density, but the community questioned the effectiveness compared to traditional treatments like finasteride.

community The Real Cause Of Androgenetic Alopecia

675 upvotes 1 year ago

Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.

community PYRILUTAMIDE PHASE 3 RESULTS : No statistical significance

124 upvotes 2 years ago

The phase 3 trial results for Pyrilutamide showed no significant difference from the control treatment in increasing hair count, leading to the company halting its development. Users discussed their disappointment and skepticism about hair loss treatments, with some mentioning other treatments like Minoxidil, Finasteride, and RU58841.
