Quantification of TSPO protein in autopsied human brain. (a) Immunoblots of TSPO in the pooled tissue standards, in the commercial N-His-tagged recombinant human TSPO-3462H and in human adrenal samples with monoclonal (EPR5384, 1:100K and MA5-24844, 1:30K dilution) and polyclonal (PA5-75544, 1:10K) antibodies. (b) Standard curves for the recombinant TSPO. Note more abundant TSPO in adrenal than in brain for both EPR5384 and MA5-24844, polymer protein bands of the recombinant TSPO, high molecular weight non-specific reactions for PA5-75544, and detection of a TSPO fragment but not 18 kDa TSPO by PA5-75544 in human adrenal samples.

        Ask a question
        How does TSPO affect neuroprotection? 12/01/2022

        TSPO has an impact on neuroprotection by modulating mitochondrial function to affect the survival and death of nerve cells. Specific mechanisms include inhibition of apoptosis and alleviation of oxidative stress.

        What are the challenges and prospects of current research on TSPO? 05/23/2022

        At present, the research on TSPO faces some challenges, such as the difference in the expression of TSPO in various tissues, the functional changes of TSPO in different disease states, and the interaction between TSPO and other molecules. However, with the continuous advancement of technology and the in-depth understanding of the functions of TSPO, it is expected that there will be greater breakthroughs in drug design and treatment strategies for TSPO in the future.

        How is TSPO involved in the synthesis and transport of cholesterol? 04/25/2022

        This protein regulates the permeability of mitochondrial membranes to cholesterol by binding to cholesterol transporters, thereby affecting cholesterol synthesis and trafficking.

        Is TSPO associated with a variety of diseases, 10/29/2020

        Since TSPO is associated with a variety of diseases,it may be a therapeutic target for a variety of diseases, such as neurodegenerative diseases, cancer, and mental disorders. Some progress has been made in the design and development of drugs for TSPO.

        How to detect the expression and function of TSPO? 04/18/2020

        Commonly used TSPO detection methods include immunohistochemistry, western blotting, flow cytometry, etc. In addition, TSPO ligands can also be used for binding experiments or functional experiments to study their biological functions.

        What circumstances does the expression level of TSPO change? 04/07/2020

        The expression level of TSPO changes in a variety of physiological and pathological conditions, such as hypoxia, ischemia, inflammation, aging, etc. These changes affect the function of the mitochondria, which affects the survival and death of cells.
