Enzymatic kinetic resolution of aliphatic and benzylic amines leading to (S)-amides was achieved by using alkaline protease as the catalyst and N-octanoyl glycine trifluoroethyl ester as the acyl donor; enantioselectivity ranged between 4 to 244, while reaction times were dramatically shortened and ranged between 15 min to 6 h.

Background & Aims: Hepatocyte transplantation has shown promise for genetic diseases of the hepatocytes but to date has shown limited efficacy for non-genetic forms of severe liver injury. Limited cell engraftment and poor function of donor hepatocytes in recipient livers impacts the clinical utility of hepatocyte cell therapy. The mechanisms underpinning this are poorly understood.

Background: The molecular etiology of tau-derived neurodegeneration remains poorly understood, reflected in the low success rate of clinical trials. Hence, aquiring a better understanding the molecular basis of tauopathies is a critical need.
Objective: To develop a versatile and reproducible system to study tau aggregation with high spatiotemporal control through optogenetics that will aid in investigating the differences in tau aggregation kinetics, the burden the burden of tau isoforms, and mutations and that will be suitable for high-throughput analysis of tauopathy-related mechanisms.

Background: Knowledge of the chemical composition of amyloid plaques and tau tangles at the earlier stages of Alzheimer's disease (AD) pathology is sparse. This is due to limited access to human brain during life and at the earlier stages of AD pathophysiology and technical limitations in quantifying amyloid and tau species at a subcellular level. Understanding the chemical composition of plaques and tangles, how rapidly they grow and what factors drive growth is important for developing and refining therapeutics.

Background: The ability to profile gene expression at the single-cell resolution offers the unprecedent opportunity to define the complex cellular heterogeneity of the brain in response to pathology. However, single-cell transcriptomics, particularly within the context of postmortem human brain samples, only provide a static snapshot of the underlying transcriptional mechanisms driving the initiation and progression of diseases.
Method: To gain a more comprehensive picture of disease-associated transcriptional programs, our research integrates single-cell genomics with cellular reprogramming techniques for data-driven mechanistic studies with human-based cellular models of the brain.
