translocator protein and neurodegeneration: insights from Alzheimer’s disease

Neural Regeneration Research 2025年第4期20卷 1090-1091页

作者： Arpit kumar Pradhan Rainer Rupprecht Gerhard Rammes Klinik für Anaesthesiologie und Intensivmedizin der technischen Universität München Klinikum rechts der IsarMunichGermany Graduate School of Systemic Neurosciences Ludwig-Maximilians-Universität MünchenMartinsriedGermany Department of Psychiatry and Psychotherapy University RegensburgRegensburgGermany

the 18 kDa translocator protein(tSPO)located on the outer mitochondrial membrane regulates several key cellular processes including mitochondrial homeostasis,cholesterol transport,apoptosis,cell proliferation,and maintenance of mitochondrial health(Rupprecht et al.,2022,2023).tSPO is expressed in both peripheral organs and the central nervous system,with a more pronounced expression in tissues that produce *** main reason why tSPO has garnered so much attention is because it plays a key role in neurosteroidogenesis by transferring cholesterol from the outer to the inner mitochondrial membrane,which is the rate-limiting step in neurosteroid synthesis.A cholesterol-recognizing amino acid consensus domain has been identified in the cytosolic C terminus of the tSPO protein by both in vitro and site-directed mutagenesis experiments(Li et al.,2001).However,the role of tSPO in the process of neurosteroid synthesis has been challenged by several studies,particularly tSPO knockout models,which suggest that tSPO removal does not affect the phenotype or the system’s viability(tu et al.,2014).However,ligands targeting tSPO have been shown to enhance levels of neurosteroids which suggests that neurosteroidogenesis is one of the major functional roles mediated by the tSPO protein.

Airway management of morbidly obese patients is challenging due to inherent anatomical and physiological variations.[1]the frequent association of compromised hemodynamics,hypoxemia,or acidosis in an emergency department(ED)setting adds to the difficulty of the *** airway management position(RAMP),awake fiber-optic guided intubation,use of intubating laryngeal mask airway(ILMA),and video-laryngoscope are a few techniques that have been described to tackle difficult airways in these patients.[2]Studies have shown that the availability of fi ber-optic scopes(3%–60%),videolaryngoscopes(39%–88%),and laryngeal mask airways(LMA)(65%–83%)varies in different ED settings.[3,4]Furthermore,a lack of adequate training and the need for time-bound resuscitation make implementation of the above techniques challenging.
