Introduction: The aim of this meta-analysis was to evaluate the efficacy and safety of mesenchymal stem cells (MSCs) for the treatment of knee osteoarthritis (OA).
Methods: The PubMed, Embase, Cochrane Central Register of Controlled Trials, Scopus and Web of Science databases were searched from inception to May 6, 2024 to identify randomized controlled trials that compared MSCs and placebo or other nonsurgical approaches for treating OA. Two investigators independently searched the literature and extracted data, and conventional meta-analyses were conducted with Review Manager 5.3. The outcomes included pain relief, functional improvement, and risk of adverse events (AEs).
Results: A total of 18 articles were included. Overall, MSCs were superior to placebo in terms of relieving pain and improving function at the 12-month follow-up. However, the differences in treatment-related AEs were not significant.
Conclusion: MSCs may relieving pain and improving function of OA. The limitations of this study include the high heterogeneity of the included studies. Additionally, the follow-up time in the included studies was relatively short, so more clinical trials are needed to predict the long-term efficacy and safety of MSCs.

Background: Alzheimer's disease (AD) agitation is a distressing neuropsychiatric symptom characterized by excessive motor activity, verbal aggression, or physical aggression. Agitation is one of the causes of caregiver distress, increased morbidity and mortality, and early institutionalization in patients with AD. Current medications used for the management of agitation have modest efficacy and have substantial side effects.

CT1812 reduces the affinity of Aβ oligomers to bind to neurons and exert synaptotoxic effects. This phase 2, multi-center, international, randomized, double-blind, placebo-controlled trial assessed safety, tolerability and effects of CT1812 on cognitive function in individuals with AD.

Background: The DL-3-n-butylphthalide (NBP), a multi-target neuroprotective drug, improving cognitive impairment in patient with vascular cognitive impairment has been confirmed. The efficacy of NBP in patients with cognitive impairment due to Alzheimer's disease (AD) remains unknown. This study aimed to evaluate the efficacy and safety of NBP in patients with mild cognitive impairment (MCI) due to AD though a clinical randomized controlled trail.

Background: Developing drugs for treating Alzheimer's disease (AD) has been extremely challenging and costly due to limited knowledge on underlying biological mechanisms and therapeutic targets. Repurposing drugs or their combination has shown potential in accelerating drug development due to the reduced drug toxicity while targeting multiple pathologies.
Method: To address the challenge in AD drug development, we developed a multi-task machine learning pipeline to integrate a comprehensive knowledge graph on biological/pharmacological interactions and multi-level evidence on drug efficacy, to identify repurposable drugs and their combination candidates RESULT: Using the drug embedding from the heterogeneous graph representation model, we ranked drug candidates based on evidence from post-treatment transcriptomic patterns, mechanistic efficacy in preclinical models, population-based treatment effect, and Phase 2/3 clinical trials.

Background: Tau proteins aggregate in a number of neurodegenerative disorders known as tauopathies. Various studies have highlighted the role of microtubule-binding domains in the intracellular aggregation of Tau protein.
Method: Using a library of synthetic VHHs humanized in collaboration with Hybrigenics, we have developed a number of anti-tau VHHs.
