The perfusion culture of primary hepatocytes has been widely adopted to build bioreactors for various applications. As a drug testing platform, a unique vertical-flow bioreactor (VfB) array was found to create the compaction culture of hepatocytes which mimicked the mechanic microenvironment in vivo while maintaining the 3D cell morphology in a 2D culture setup and enhancing the hepatic functions for a sustained culture. Here, we report the methodology in designing and fabricating the VfB to reach ideal bioreactor requirements, optimizing the VfB as a prototype for drug testing, and to demonstrate the enhanced hepatic function so as to demonstrate the performance of the bioreactor. This device enables the modular, scalable, and manufacturable construction of a functional drug testing platform through the sustained maintenance of model cells.

Molecular Identification and Antifungal Susceptibility of Fusarium spp. Clinical Isolates.

Mycoses

January 2025

Clinical Microbiology Laboratory, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mexico City, Mexico.

Background: Accurate identification of Fusarium species requires molecular identification. Treating fusariosis is challenging due to widespread antifungal resistance, high rates of treatment failure, and insufficient information relating antifungal susceptibility to the clinical outcome. Despite recent outbreaks in Mexico, there is limited information on epidemiology and antifungal susceptibility testing (AST).

Immune infiltration plays a significant role in the pathogenesis of rheumatoid arthritis (RA). Cuproptosis, a newly characterized form of programmed cell death, remains insufficiently investigated regarding its genetic regulation of immune infiltration in RA. Data from the GEO database were analyzed to determine the relationship between cuproptosis-related genes and immune infiltration.

Background: Botulinum neurotoxin type A (BoNT/A) is the most potent and prevalent neurotoxin known to cause botulism, and is also widely used in medical and cosmetic applications. The detection of BoNT/A is of great significance for botulism diagnosis and drug potency determination. Currently, the mouse bioassay (MBA) has long been the gold standard method but has disadvantages of ethical concerns, long testing duration, and high costs.

With the rapid development of epidermal growth factor receptor (EGFR) gene testing of lung adenocarcinoma patients has been routinely carried out, EGFR mutations are also possible for some small samples of non-smoking female lung squamous cell carcinoma patients. This increases the opportunity for targeted therapy for this group of patients. However, drug resistance in patients with lung squamous cell carcinoma during targeted therapy is an important factor affecting subsequent treatment.

Point of view: Challenges in implementation of new immunotherapies for Alzheimer's disease.

J Prev Alzheimers Dis

Division of Neurogeriatrics, Department of Neurobiology, Care Sciences and Society, Karolinska Institutet, BioClinicum, 171 64 Solna, Sweden; Theme Inflammation and Aging, Karolinska University Hospital, 141 86 Stockholm, Sweden.

The advancement of disease-modifying treatments (DMTs) for Alzheimer's disease (AD), along with the approval of three amyloid-targeting therapies in the US and several other countries, represents a significant development in the treatment landscape, offering new hope for addressing this once untreatable chronic progressive disease. However, significant challenges persist that could impede the successful integration of this class of drugs into clinical practice. These challenges include determining patient eligibility, appropriate use of diagnostic tools and genetic testing in patient care pathways, effective detection and monitoring of side effects, and improving the healthcare system's readiness by engaging both primary care and dementia specialists.
