Virtually all natural proteins are built from only 20 amino acids, and while this makes possible all the functions they perform, the ability to encode other amino acids selected for specific purposes promises to enable the discovery and production of proteins with novel functions, including therapeutic proteins with more optimal drug-like properties. The field of genetic code expansion (GCE) has for years enabled the production of such proteins for academic purposes and is now transitioning to commercialization for the production of more optimal protein therapeutics. Focusing on , we review the history and current state of the field. We also provide a review of the first generation commercialization efforts, the lessons learned, and how those lessons are guiding new efforts. With continued academic and industrial progress, GCE methodologies promise to make possible the routine optimization of proteins for therapeutic use in a way that has only previously been possible with small-molecule therapeutics.

Alzheimers Dement
December 2024
Instituto Neurológico de Colombia, Medellin, Antioquia, Colombia.
Background: This study examines an exceptional case of CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy), a hereditary cerebrovascular disease caused by a mutation in the notch3 gene. In contrast to typical cases manifesting before the age of 50 with migraines, this report highlights an atypical presentation in a 70-year-old woman with no history of migraines nor cognitive impairment.
Method: The patient, with a history of type 2 diabetes, hypothyroidism, and dyslipidemia, was initially treated for cognitive impairment and behavioral changes under suspicion of autoimmune encephalitis.

College of Medicine, University of Ibadan, Ibadan, Nigeria.
Background: Understanding the genetic underpinnings of Alzheimer's disease is crucial for advancing research and developing targeted interventions. Genomic research in dementia in Africa is of utmost importance based on recent reports from studies in African Americans that African ancestral gene is associated with lower risk effect for developing AD. However, dementia related genetic study is an evolving research in sub-Saharan Africa with peculiar challenges influencing participant recruitment.

According to the Alzheimer's Association (2021), by 2050, people ages 65 and above with Alzheimer's are estimated to grow to 12.7 million-rising in prevalence and severity.

Like the rest of Latin America, it is grappling with the aging of its population and an increase in risk factors. Despite this, there are currently no studies on the incidence of dementia in the national territory.

Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.
Background: Previous studies have reported various prodromal symptoms and comorbidities that precede the development of dementia. In this study, we comprehensively investigate the impact of genetic predispositions to multiple comorbidities on the risk of incident dementia.
Methods: Our study included 377,653 participants of European descent from the UK Biobank, comprising 370,183 controls and 7,470 cases of incident dementia.
