Cystic fibrosis arises from loss-of-function mutations in the CFTR gene, disrupting epithelial ion homeostasis and impairing airway mucus clearance. While missense mutations typically lead to minor conformational alterations that can be rectified with pharmacological interventions, nonsense mutations pose a more significant therapeutic challenge. In this research, we established an in vitro model of cystic fibrosis (CF) employing patient-specific induced pluripotent stem cells (iPSCs) that contain the CFTR-S308X n…

In November 2022, 68% of the population received at least one dose of COVID-19 vaccines. Owing to the ongoing mutations, especially for the variants of concern (VOCs), it is important to monitor the humoral immune responses after different vaccination strategies. In this study, we developed a SARS-CoV-2 variant protein microarray that contained the spike proteins from the VOCs, e.g., alpha, beta, gamma, delta, and omicron, to quantify the binding antibody and surrogate neutralizing antibody. Plasmas were collected…

Abstract Objectives RA is an autoimmune disease characterized by chronic inflammation and joint destruction. Biologics are crucial to achieving treat-to-target goals in patients with RA. The global spread and continuous variation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) necessitate the monitoring of variant-specific humoral responses post-vaccination. The aim of this study was to investigate how different biologic treatments for vaccinated RA patients might affect their neutralizing antibodi…
