However, inflammatory processes play a complex role in Alzheimer`s progression, with some aspects of inflammation eliciting beneficial effects, while other aspects accelerate the disease process. In order to develop effective immune therapies for the treatment of Alzheimer`s disease, we are working to identify (i) biomarkers that can distinguish detrimental versus trophic modes of inflammation, and (ii) therapeutic strategies that can inhibit detrimental inflammation whilst promoting beneficial effects.<\/p>\n<h3 style=\"text-align: justify;\"><\/h3>\n<h3 style=\"text-align: justify;\">\u00a0<img loading=\"lazy\" decoding=\"async\" class=\"wp-image-251 alignright\" src=\"https:\/\/neurobiologyaging.com\/wp-content\/uploads\/2016\/06\/web-figure_TSPO-PET.jpg\" alt=\"Microsoft PowerPoint - web figure_TSPO therapeutic\" width=\"594\" height=\"180\" srcset=\"https:\/\/neurobiologyaging.com\/wp-content\/uploads\/2016\/06\/web-figure_TSPO-PET.jpg 2615w, https:\/\/neurobiologyaging.com\/wp-content\/uploads\/2016\/06\/web-figure_TSPO-PET-150x45.jpg 150w, https:\/\/neurobiologyaging.com\/wp-content\/uploads\/2016\/06\/web-figure_TSPO-PET-300x91.jpg 300w, https:\/\/neurobiologyaging.com\/wp-content\/uploads\/2016\/06\/web-figure_TSPO-PET-1024x311.jpg 1024w\" sizes=\"auto, (max-width: 594px) 100vw, 594px\" \/><\/h3>\n<h3 style=\"text-align: justify;\"><strong><a id=\"R1\"><\/a>Aging, neurosteroidogenesis and neuropsychiatric disease<br \/>\n<\/strong><\/h3>\n<p style=\"text-align: justify;\">Neuroactive steroid hormones are potent endogenous neuromodulators affecting complex behaviors including anxiety and depression, altering susceptibility to neuropsychiatric disease and have been implicated in cognitive aging.

Several different ligands for TSPO currently used as PET neuroimaging agents for visualizing inflammatory responses in aging and AD. TSPO ligands have also been\u00a0identified as potential therapeutic agents, eliciting pleiotropic neuroprotective and cognitive benefits. We have\u00a0identified TSPO ligands as a promising therapeutic approach to both prevent and treat Alzheimer`s disease. However, although TSPO expression is closely linked to inflammation in aging and AD, the specific role of TSPO in AD pathogenesis remains poorly understood.
