Nanosuspension (also called nanocrystal suspension or nanocrystal) could significantly enhance the saturated solubility and dissolution of insoluble drugs, and improve their bioavailability by reducing particle size and increasing the specific surface, which could then solve the delivery problems of the poorly soluble active ingredients and effective parts of Chinese materia medica (CMM). Based on the brief summaries of nanosuspension preparation methods, this paper would mainly review the and behaviors of poorly soluble CMM nanosuspension, discuss and analyze its problems, so as to provide reference and thinking for the further study of nanosuspension drug delivery system of poorly soluble CMM and promote the development and perfection of nanosuspension technology in CMM.

Background: Soluble Aβ oligomers (AβOs) induce synapse dysfunction, leading to cognitive impairment and memory deficits in Alzheimer's disease (AD). Our laboratory and several research groups characterized neurexin family members' physiological roles, pivotal synaptic adhesion molecules for development, plasticity, and maintenance. Beyond their normal functions, we found neurexins binding to AβOs causes AβO-induced neurexin dysregulation.

Cholinergic deficiency and neuroinflammation are the two main factors of Alzheimer's disease. Recent studies have shown that water-soluble ginseng oligosaccharides (WGOS) derived from Panax ginseng roots can protect against scopolamine-induced impairments in learning and memory. However, the fundamental mechanisms remain unclear for the most part.

Background: Progranulin (PGRN) haploinsufficiency is a major risk factor for frontotemporal lobar degeneration with TDP-43 pathology (FTLD-GRN). Multiple therapeutic strategies are in clinical development to restore PGRN levels in the CNS, including gene therapy. However, a limitation of current gene therapy approaches aimed to alleviate FTLD-associated pathologies may be their inefficient brain exposure and biodistribution.

Background: The misfolding and aggregation of the tau protein into neurofibrillary tangles constitute a central feature of tauopathies. Traumatic brain injury (TBI) has emerged as a potential risk factor, triggering the onset and progression of tauopathies. Our previous research revealed distinct polymorphisms in soluble tau oligomers originating from single versus repetitive mild TBIs.

Background: Chronic stress has been linked to an increased risk for various health issues, including Alzheimer's disease (AD). While novel therapies for AD have improved disease prognosis, a deeper understanding of the link between stress and AD may delineate potential novel preventative treatments. Within the stress system, corticotrophin-releasing factor receptor 1 (CRFR1) has been shown to influence AD pathological hallmarks.
